I have mentioned before that EV's have a sweet spot in the transportation market at this point. Commute to work from home. Back to home from work. Set your 220Volt charger to power up and charge vehicle overnight during off peak hours. Wash, Rinse, Repeat. It is the demand from consumers for greater travel range and going past the commute that is pushing some of the advancements in battery technology and additional charging stations. The advancement in battery technology of the Sodium battery is one I personally find most interesting. Sodium substitute for Lithium will greatly reduce the cost and environmental impact of EV batteries. They fast charge, do not present a fire danger, do not lose capacity in cold are just a few of the advantages. VW has introduced an EV with Sodium batteries in China. Cost is 10,000 dollars. Only has a range of 150 miles, but will fast charge in 10 minutes. Demand is high. 3 years from now, the EV market will look completely different than it does today. PS. I do not own an EV. My primary driver is a Prius plug in.
