kWh. Because even if the charging station may be able to provide a higher amount of power (kW) your EV may not charge that fast. That is one reason that I never charged at a paid public station with my previous EV truck (and probably also not with my new EV truck) since it had a charger that would not take more than about 1.5kW at either 110 or 208V so the per time billing that is common on chargers and geared towards the max Level 2 charging of 6.6 kW consumption, worked out to be a ridiculously high cost per kWh for my EV, so I never bothered to use a paid charger and always found an alternative solution. Tens of thousands of Leaf owners also face the issue that they can only charge at 3kW so why would they have to pay as if they were sucking power at 6kW rate? It would be similar to pull up to a gas station and instead of counting the actual gallons delivered into your tank, it would count how fast it would have been possible to deliver fuel if you would have squeezed the trigger to the max - which you might not if that makes the back-flow detector shut off all the time, so you pull the trigger halfway to refuel slower and as a result your 15 gallons fillup is charged to you as 35 gallons in cost because the pump could have been able to deliver that amount in that time. Seems unfair, no?
So, we should make sure that the delivered energy is counted: gallons delivered for liquid fuel vehicles and kWh of Energy delivered for EVs.

Could be different prices for L2 and fast charging. Once there are enough charging stations in an area, drivers could choose based on price they see, rather than poking around a smartphone app and trying to decipher the various charges online. Might make the cost of charging more competitive and less random.

Their may be some game by reducing weight I don't think aerodynamics is going to play into it unless it's a sports car. Most people purchase a car > For other reasons then economy. Comfort, utility, whatever fits their lifestyle. Weight is the greatest factor in the range of your vehicle. I have two electric vehicles and they both follow the rule of thumb weight/10 = watts per mile. This changes based on how you drive but that's the average again. I believe battery technology will continue to improve for another 10 years. I think the bigger problem is the charging infrastructure. The cars are good enough now and the batteries are good enough now there's just a shortage of places to charge. They shouldn't start charging stations at every gas station preferably fast chargers.they need to quit giving away free energy and start charging for the electricity so that the stations are reliable and maintained by someone making a profit. Then there would be no obstacle as to where you could drive your car and that's coming I'm sure of that. > Sent from my iPhone > >> On Sep 12, 2016, at 10:10 PM, Lawrence Rhodes via EV <ev@lists.evdl.org> wrote: >> >> Clearly the next frontier in electric automobile design is not the battery but the efficiency of the vehicle. If it is lighter and more aerodynamic this will allow the use of smaller packs and longer range. With smaller packs the charging time is reduced taking away the #1 problem with electric cars. The charging time. Currently Solar Cars from the Tesla Crusier Class at the World Solar challenge with out solar assistance have a 400 mile range on 15kw of batteries. Of course the vehicles weigh under 1000 pounds have seating for four and the tires are very narrow. I've been in Stella. It is comfortable and practical. The next electric vehicle I build will be light and efficient.
