Re: The charger numbers seem a bit low.
Charging fast enough to do 200 miles from a 15 minute charge puts a lot of stress on the battery shortening its lifespan. If the charge rate is limited to half or less of the maximum discharge rate then the lifespan will be much longer than if it is charged at a very high rate.
If you have to have an EV then follow the rules below for maximum battery life when possible
1) Use a low rate overnight charge (7kW or below) rather than fast chargers
2) Do not discharge the battery below 20% (lithium ion batteries last much longer when they are not fully discharged)
3) If possible terminate the charge below 95% capacity (again this is much kinder to lithium ion batteries)
I know that the above rules are not always practical but when they are the battery lifespan will be much longer.
