I know this is a press piece, but...
An electric car is more than just a battery, of course. Sophisticated electronics are needed to manage the flow of electrons into and out of the battery as well.
No, there really isn't a need for "sophisticated" electronics. The electronics of a battery charger is quite basic. Apply voltage and limit the charge current.
EVs are extremely simple in operation. It would be nice if manufacturers exploited that fact to bring prices down.
