Electric Cars – Saving Real Money or Arbitrage Opportunity?

Electrek has reported an amazing set of numbers on a Tesla S:

A Tesla Model S hits 300,000 miles in just 2 years – saving an estimated $60,000 on fuel and maintenance

The vehicle is owned by Tesloop, a company that offers rides in Tesla vehicles.

A large part of this difference is due to the fact that the car is being used within an area that has extensive Tesla SuperChargers. So all the electricity is “free” (paid for as part of the purchase price of the vehicle). Also parts of the repairs and maintenance were largely paid for under the warranty. The powertrain warranty is for 8 years and includes unlimited mileage. This means that at the same annual usage rate the warranty would cover 1.2 million miles or 1.93 million kilometres.

The key question here is whether Tesla is losing money on this arrangement. If so, the savings are artificially inflated. The answer to part of that question is in the pricing models that Tesla introduced early in 2017. Before that date all Tesla S vehicles received free power on the Tesla Supercharger Network. After that date only the first 400 kWh per year are free. After that you get charged a fee for your power when charging . The fee varies between locations.

So there is no doubt that Tesla has been heavily subsiding the Tesloop operating costs. A smart business move to spot an arbitrage opportunity.

The 400 kWh is estimated to provide power for 1000 miles of driving (1609 kilometres). In Australia the current (sic) charge on the Tesla Supercharger is A$0.35/kWh.(https://www.tesla.com/en_AU/support/supercharging). so the energy cost per kilometre of driving is approximately 8.7 cents. This compares to my petrol Toyota Corolla Hatch at 8.1 cents per kilometre (combined urban/extra urban mileage claim of 6.7L/100km and fuel at  121 cents per litre). Fuel efficiency is worse in urban driving but the Tesla Superchargers are mainly for highway travel so that this is a fair comparison.

Two other comparisons bear looking at. In Illinois the charging rate is US$0.15 per kWh. This equals A$0.188 (RBA quoted exchange rate August 30th 2017) and changes the per kilometre cost to 4.7 cents.  Secondly, our current at home shoulder and off peak rates are A$0.1257, which reduces the per kilometre cost to 3.12 cents. Of course we would have to pay for a charging unit as well. If we amortise that cost then the total cost might be 4 cents per km. That is half my current fuel costs, or a saving of about $600 a year on 15,000 km.

If we use 4 cents as a reasonable figure then the cost difference for an electric vehicle travelling 100,000 km a year as a car ride service/taxi is $4,000. That is a significant advantage for an electric share vehicle over a fossil fuel vehicle. That number starts to really add up if you own 20,000 of them in a fleet ($80 million a year).

If we go to the non- fuel car costs. RACQ estimates that the private ownership costs of running a medium sized car in Australia are around 65-72 cents per kilometre. More than 50% of these costs are interest costs (about 8.2 cents) and depreciation costs (about 29.5 cents). Registration and insurance and other on road costs are at about 14.9 cents. This leaves about 7.5 cents for repairs and maintenance plus tyres after accounting for fuel costs. The vast majority of that being repairs and maintenance (median is about 7 cents). In the Tesloop case the scheduled repairs and maintenance costs were US$6,900 for 300,000 miles (482,802 km). This equates to A1.79 cents per kilometre. If we go back to my Toyota which has a fixed price service of A$480 a year then that costs is A3.2 cents per kilometre at 15,000 km per year. The reality is that I drive a little less so the cost is 3.7 cents.

If we go back to the RACQ numbers the Tesla Model S 75 version has fuel costs of 4.73 cents per kilometre. It also has maintenance costs of A8.91 cents. This seems high given the Tesla Loop experience but may just be a function of  the much higher mileage.

The Tesla S is a luxury vehicle and so its costs are likely to be higher than a standard vehicle. Lets look at the Chevy Bolt. In this analysis I have been helped by an excellent article by Steven Sinofsky at Learning by Shipping and Insideevs : Chevrolet Bolt Requires Almost No Maintenance For First 150,000 Miles.

The maintenance schedule (H/T Steven Sinofsky) for the Bolt is:

Chevy Bolt maintenance schedule Sinofsky

Insideevs estimates that if you do the very scant maintenance yourself the cost for maintenance for the first 150,000 miles (241,000 km) is US$150 (yes you read that right) while Steven says:

“Yep you read that correctly, during my entire three year lease there’s nothing for me to do. I never have to go to the dealer” – Steven Sinofsky

So one way or another routine maintenance is very low.

In terms of fuel efficiency the Bolt is rated at 238 miles (383 km) on a 60 kWh battery although city driving has a better range due to regenerative braking, and highway driving is poorer due to a poor drag coefficient.  This results in 6.38 km per kWh and if we use the off peak rate I pay then that is A1.97 cents per kilometre (note Steven was more conservative in his mileage calculations which work out to about A2.39 cents per km using my electricity costs).

This is a lot of figures so as a summary I have made up a small table:

Fuel Costs Maintenance Costs Total
Tesloop Tesla S 0 1.79 1.79
Toyota Corolla Hatch (Mine) 8.1 3.7 11.8
Tesla S (RACQ) 4.7 8.91 13.61
Luxury Vehicle (Ave RACQ) 7.06 10.2 17.26
Chevy Bolt (first 60,000km – but generally representative) 1.97 0 1.97

Now I know that I have not made a fair comparison between the Bolt and the Tesla S. In part because they are completely different vehicles, and because I have only included routine maintenance servicing for the Bolt.  There will be non -routine costs in the maintenance costs. The actual costs of those the owner will be in part determined by warranty systems. The RACQ figures appear to include a capped servicing arrangement with Telstra.

What we can say is that there are significant operating costs for the new electric vehicles, as compared to standard ICE vehicles. Even if we add in the Tesloop Tesla S maintenance costs as an estimate for the Bolt’s costs, the Chevy Bolt’s operating cost for fuel and maintenance is still only 3.76 cents per kilometre, compared to my Toyota costs of 11.8 cents. Even though I have only included my fixed costs servicing which is well below the costs shown in the RACQ figures.
 
That comparison is also unfair as the costs associated with the Tesla S are high due to its luxury model status. You can see the details of the repairs and maintenance receipts by going to : Tesla Model S Hits 300,000 Miles with less than $11,000 maintenance costs  and registering for their Google Docs page. These include warranty repairs done at no cost. I was unable to reconcile the costs to the article description as some costs appear to be missing but what is in there is in the following table:
Date Item Cost
18/08/2016 Replace 12V battery 171.33
24/10/2016 replace brake pads and rotors 1759.42
4/11/2016 Right Rear Door handle 961.96
21/11/2016 left front door handle 962.18
20/02/2017 wheel liner, rear diffuser, front aero shield, water ingress on headlights 2176.2
7/03/2017 Air conditioner , other pages to receipt are missing 2800.12
15/03/2017 Air conditioner, passenger door handle 656.64
Total 9487.85

As you can see the majority of the maintenance costs excluding the issue with the headlights and brake replacements related to the air conditioner and door handles. Some of these are likely to be costs associated with the luxury/technology parts of the doors, and early model issues. I would expect that costs for a standard production model would be much lower.

The point of all this analysis is work for our book to look at adoption timelines and business models for electric and autonomous vehicles.

In this case it is the headline number of how much it takes to run your car. That is because people get this in their face every week whereas the main costs of finance and depreciation are more removed from their experience. Once we move to the full question of costs we have to look at those more closely. we will do that in the next few days. Then we have to look at fleet options versus personal ownership.

We will do some more sophisticated modelling as we firm up the assessment for the book.

I am writing a book on autonomous vehicles with Dr Chris Rice of the University of Texas Austin. It is called Rise of the Autobots: How Driverless Vehicles will Transform our Economies and our Communities. Stay tuned for more excerpts as we finalise the book.

Sell Your Crash Repair Business Now*

*this should not be taken as financial or business advice. If you own a crash repair business please take professional advice before making any decisions.

I am just going through the process of getting some minor damage repaired on our car and have been ruminating on the future of the insurance and repair model when we have driverless (autonomous) cars. This was also prompted by a couple of stories in The Age here in Melbourne:

Crash repair: How Ray Malone became head of ASX-listed company AMA Group

and

Driverless vehicles technology to roll out on the Tulla under trial

 

The first story describes how Ray Malone has built a Australia’s largest crash repair business, and is aiming to grow it even further. That would seem to go against the title of this post but it actually feeds into my thinking because Ray’s company provides wholesale service aftercare which will be vital in the scenario I am describing.

The second story is about how trials of driverless cars are starting here in Melbourne. This follows a large number of trials that are being conducted in various countries around the world.

Once we move to a reasonably widespread adoption of autonomous/driverless cars the local crash repair business will basically disappear except for a few large operators like Ray Malone but even his business could be under threat . The key reasons for this are:

1/ It has been forecast that autonomous cars will significantly reduce the number of car accidents that occur. This is based largely on the statistics that human error causes more than 90% of traffic crashes. So if we can eliminate the crashes caused by idiots, people under the influence of drugs and alcohol, and people driving tired or angry (Police looked into the deaths of 86 people on Victorian roads last year and found that in more than 10 per cent of cases the driver had experienced a traumatic or upsetting event.) we can significantly reduce the number of accidents.

Against this argument is that autonomous cars supplying a transport service may result in people travelling further and perhaps take more risks. Certainly it will allow elderly people who cannot drive, and young people who do not have a licence to travel in cars more than they otherwise would. There have also been arguments that because we feel safer we may take more risks as pedestrians or cyclists.  If we are conservative and say that only 50% of accidents caused by human behaviour will be eliminated we still have a significant fall in accidents.

2/ It is highly likely that we will see large fleet models emerge where large numbers of people choose not to own a vehicle. If the overall travel costs are lower than owning your own vehicle, and you can get a vehicle anytime you need one then the convenience of transport as a service outweighs the personal ownership model.  The economics for fleet owners are different than for individual owners when it comes to crash repair services. Fleet owners will want large scale service operations to reduce costs or will pay far less for the services of smaller scale operators. This feeds into a large supplier (such as Ray Malone’s company) snapping up more business. Larger scale crash repair businesses will benefit from the economies of scale that allow them to use new technologies such as robotics to increase throughput and reduce costs.

3/ The model for crash repair business location will change. Currently crash repair businesses are located in scattered locations throughout the suburbs and inner city. This is because if I want to take my car in for crash repairs there is a significant time cost for me to take my car to a location that is not near to my house or business. I have to travel to the crash repair business, and then get back to my home or place of work. So I want the crash repair business to be reasonably close. The location is mainly driven by the customer. If my personal driverless car needs crash repairs it can drive itself to the crash repair site, and a fleet service or a shared personal car service can replace my transport needs in the meantime.

If I was asked to drive my car (actual damage pictured below) to a service centre 40 km away I would not be very happy, but if my car can take itself then location becomes much less important and the costs of the business become far more important. Locating the crash repair business in areas of lower property costs with good transport links makes far more sense. It also means that the employees of the business will have lower property costs if they live locally. We already see this model in light manufacturing and food processing/handling facilities locating around hubs on ring roads, away from  inner suburbs with high property prices.

If a fleet ownership model predominates over personal ownership this effect will be even higher as large scale fleets look for cost reductions through economies of scale.

So if we summarise all the factors together if we assume a 45% reduction in total accidents (50% of human error crashes) and a tripling of scale that comes from the changes described above we get an 82% reduction in the number of crash repair businesses in any city.  I believe that the changes in scale may be even higher and we may end up with only 5-10% of the number of current crash repair businesses being economically viable.

If I own a crash repair business in any suburb in any of our major cities I will come under pressure from a high scale panel beater business set up on the fringes of the city with lower property costs.

So, if you are a crash repair business:

  1. Assess whether now is a good time to sell to someone else who does not understand these changes.
  2. If you think I am wrong then you should suspend that thought for just a few minutes and  think about what it means to your business and your assets if I am right. Even if you think that chance is only 5% you should set up a series of questions for yourself to monitor in coming years so that you can change your mind if the changes start to happen. Those questions include:
  • Is the practical outcome of accident reduction matching the rhetoric of the technology experts and the modellers? Look for signs of early change, cities where adoption is at the forefront of the change and make an assessment as to whether the predictions on accident reduction are true (or even going to be exceeded) and then think about the timing of the implications.
  • Look for areas or cities where the first full scale mass adoption of driverless cars might take place. For example Singapore, with a small land mass, and a relatively authoritarian government might be one. This will give you early signs of what larger scale adoption might look like.
  • Is the adoption model going to be a personal one or a mass fleet one? If the model is primarily a personal one then you should be thinking about whether you can become one of the new mega panel beaters on the fringes of the city that will survive the change. If the model looks to be a primarily mass fleet adoption one then there are less possibilities. Those fleet operators will either run their own operations which are standardised and mechanised or they will use their economies of scale to drive down margins in the businesses that supply them. You can still run a good business that way but the opportunities will be limited and will require lots of capital to create the volume throughput and economies of scale required. You will have to compete with the Ray Malone’s of this world.
  • Are any early models of very large scale, city fringe located crash repair businesses starting to emerge anywhere around the world? Are they successful?
  • Are car companies changing their business models for car repairs. For instance electric cars have far less moving parts than internal combustion cars. Does that make a difference to your business model? Are modularised car construction and repair systems emerging that will increase the capacity to adopt robotic repair and maintenance systems that will advantage large throughput car repair and maintenance systems?

While these changes may take 15 years to start to significantly impact on the crash repair business, once they become obvious the window to realise the business value by sale will quickly snap shut.

This is just one of the many implications of change from the widescale adoption of driverless cars.I am writing a book on driverless vehicles with Chris Rice (@ricetopher). It is called “Rise of the Autobots: How driverless vehicles will transform our economies and our communities. Stay tuned for more writing as we develop our thinking further.

Electric Cars and the Legacy Issue

Chris Rice and I are currently writing a book on the rise of autonomous vehicles and their widespread effects across our economies (entitled Rise of the Autobots: How Driverless Vehicles will change our Societies and our Economies). One of the keys to looking at what these changes might mean and the rate at which they will occur is the speed of adoption speed of electric cars and autonomous vehicles combined together.

There have been lots of excited announcements about electric cars over the last few months including:

India to make every single car electric by 2030 in bid to tackle pollution that kills millions
The Electric-Car Boom Is So Real Even Oil Companies Say It’s Coming
When Will Electric Cars Go Mainstream? It May Be Sooner Than You Think

The reality is that the adoption of electric cars will have several bottlenecks including but not limited to:

  • Battery availability.
  • Production capacity for manufacturing.
  • The reluctance of people to adopt the technology until they are completely sure that the charging issues and the range issue have been adequately dealt with.
  • The long-term nature of the turnover of the vehicle fleet.

Both battery production and electric car production are ramping up but the last point is very important when we start looking at the critical mass needed to disrupt a range of industries, including petrol stations and their supply chains, maintenance and repair systems, and the electric power grid. Even when it becomes a sensible economic decision to purchase a new electric car over an internal combustion engine (ICE) powered car, someone with a 7 year old vehicle is not going to immediately changeover. This is both due to the capital nature of the change and the fact that if electric cars are more economical than ICE cars the resale value of second hand ICE cars will fall dramatically, reducing the interest and capacity of people to purchase a new vehicle (if purchase is the model). This will be exacerbated if the new electric vehicles also have significant advantages in autonomy.

To illustrate this issue we took a look at the vehicle fleet in New South Wales in Australia If we look at the statistics at the end of the fourth quarter in 2016 it gives us a snapshot of the vehicle legacy issue. The following graph shows the year of manufacture for light vehicles registered in NSW at the end of 2016. The majority are passenger vehicles:

light vehicle registrations in NSW 2016 Q4

Source: http://www.rms.nsw.gov.au/about/corporate-publications/statistics/registrationandlicensing/tables/table113_2016q4.html  – accessed July 24th 2017

While the 2016 manufactured vehicles are under-represented in this graph as many 2016 vehicles are registered in 2017, it nevertheless gives a clear picture of the ownership structure of light vehicles. If we look deeper in the data we see that 20.1% of the registered light vehicles are manufactured prior to 2001.

If we look at heavy vehicles we get a similar picture albeit with different percentages:

heavy vehicle registrations in NSW 2016 Q4

There are some differences in the data between light and heavy vehicles:

  • The first is that there are significantly more 2007 heavy vehicles registered than any other year. This probably relates to GFC issues.
  • The second is that the heavy vehicle curve is lower than the light vehicle curve. This probably reflects a pattern of use where heavy vehicles are sold into a secondary market that will discount vehicles significantly if the economic model is significantly different than the new vehicle one, extending the useful economic life of the vehicles. This means that the percentage of total registered heavy vehicles prior to 2001 is 34.2%, much higher than light vehicles.
  • The third is that there are many more vintage models in the light vehicle category, reflecting the motoring enthusiast and restoration market. So there are 3,379 registered light vehicles manufactured 1900-1949, but only 21 heavy vehicles for the same period.

A very simplistic look at this data says that even if every vehicle sold new in Australia was electric from say 2025 was an electric car, and the purchase patterns remained stable after 5 years we would have between 31% and 40% electric light vehicles on the road and in 10 years it would be somewhere between 50 and 60%. This pattern is highly unlikely and so the real adoption rates will be well short of that. Every year that the purchase pattern is 50% electric and 50% ICE will slow the transition as those ICE cars will be on the road for a long time.

This adoption cycle is complicated by our view that increasing automation will result in more fleet ownership models, and shared car rides, reducing the total sales of new vehicles. While this means that battery and electric car manufacturing do not have to ramp up as much to get to 100% of new sales it changes the adoption curve.

Now both those simplistic analyses assume the normal pattern of car purchases and ownership will remain in place. That is also unrealistic. All we do know is that the adoption rates will be relatively slow because of the legacy issues and the turnover of the vehicle fleet as a whole. Cars are not smartphones. We will be doing some more modelling on the possible scenarios over the next few weeks. Follow us here if you want to see them and help us think through the changes.

Re-Purposed Electric Car Batteries and Its Effects on Electric Car Adoption/Driverless Car Adoption

Last night I attended the Churchill Club event in Melbourne on the future of batteries. There was a great panel presenting and the discussions covered a range of battery technologies, including Ecoult which is commercialising the CSIRO ultracapacitor technology for lead acid batteries.

In particular I was interested in the presentation by Relectrify CEO and Co-Founder Valentin Muenzel who talked about Relectrify’s mission to use electric car batteries that were no longer useful in energy storage applications. This was interesting because as part of my research for a book that Chris Rice and I are writing on the future of driverless cars I had been looking at the adoption rates of electric cars as part of the rise of driverless cars. In that research I had come across an assessment by Ark Investments that had calculated the net present value of an electric car battery in a specific energy storage scenario as shown in the following table:

Ark Invest battery depreciation table

source: https://ark-invest.com/research/ev-batteries-value – accessed June 20th 2017

The basic principle is that while a battery in an electric car might have its performance degrade to a point where it is no longer useful for driving, that battery will still have significant storage capacity (think about your phone battery after 18 months – it still works but its capacity is reduced).  If you can buy that battery cheaply and adapt it to storage use then you have a cost effective solution.

Of course the Net Present Value calculation in the table is for a specified energy reserve use which has a higher price, and nobody buys an asset for its Net Present Value otherwise all you do is get your money back over time. In discussions with Valentin he told me that without giving away commercial secrets the model for them is about 50% of the value of a new battery. This is important because the cost of new car batteries is falling. An analysis of battery prices by Bloomberg New Energy Finance in January showed the pace of that change:

battery prices falling fast from Bloomberg

source: https://www.bloomberg.com/news/articles/2017-01-30/tesla-s-battery-revolution-just-reached-critical-mass  

Now this is the price of the battery itself which is not the same as an installed battery system but the progress has been amazing, and mirrors what we have seen in solar energy. No great basic technology breakthrough, but significant technology improvements driven by the cost learning curve. In a separate report Mckinsey has stated that electric vehicle batteries fell to $227/kWh in 2016 with Tesla claiming to be below $190 per kWh (Electric vehicle battery cost dropped 80% in 6 years down to $227/kWh – Tesla claims to be below $190/kWh) Rumours have also circulated that Tesla has got the battery costs down to $125 per kWh (Tesla is now claiming 35% battery cost reduction at ‘Gigafactory 1’ – hinting at breakthrough cost below $125/kWh) although the truth of that remains to be seen. There is no doubt about the rapid pace of changes occurring, just the quantum of that change.

Valentin and I also discussed the model for autonomous vehicles given that a fleet model or a car sharing model means that cars would travel far more kilometres in a year. For an electric car this means that the battery will reach its degradation limit more quickly as the battery would be charged and discharged more often. Interestingly for Valentin this meant that the battery would be worth more for repurposing, because outside of the energy capacity the battery still retained, its relative newness means the technology is likely to be more advanced, and safety and physical deterioration characteristics would be much better.

Given that storage is likely to become far more important in the future given changes in the energy generation mixes around the world it puts a slightly different complexion on the costs of electric cars. It is our view that the end game for driverless cars is mass fleets supplied as a service with hardly anybody owning a car. If electric car batteries only last 3 years in shared driverless vehicle but have significant re-sale value it lowers the lifetime cost of a kilometre travelled and therefore accelerates us to the point where the cost of running an electric car is lower than running a fossil fuel car. Lifetime cost factors less into individual car ownership decisions but if you own 50,000 cars in a mass fleet in a highly competitive market it becomes it becomes a much more important factor. This changes adoption rates and also the balance between fossil fuel and electric cars.

The effects of this will be lumpy as Valentin advised that different batteries have different degrees of difficulty for repurposing as stationary storage. This is related to the original design decisions made for the battery technology which were originally made with the purpose of electric cars in mind, not stationary storage. For example apparently Tesla has stated that their car batteries will not be repurposed and that is due to the design constraints in their battery technology.

A note of caution:

In a discussion with John Wood (CEO of Ecoult) he quite rightly warned me to be careful of the public statements of battery manufacturers and suppliers on their lifetime use. Given that we are talking about changes in technology and lifetimes of 10-15 years which are therefore untested in the real world, those are wise words.
