la-tsla-fan,
GM had the volt EV for couple of decades and I was interested in as well. I only drove Cad Sevilles for 3 decades. Nissan had the Leaf, among others.
However, I don't think they really cared for them and their driving ranges were like 135 miles or so. My dentist had a Nissan Leaf, a Taurus and Honda, in the 80's. I remember he said the leaf was plugged overnight and still he could go to his office and back home hardly about 40 miles and then was on charge for 12 hrs for his drive. His Taurus was most of the time in the repair shops. He said he depended on his Honda, a work horse for what he got used to.
It seems they never approached EVs seriously from what little I know. But it is understandable when you have so much infrastructure all geared producing ICE vehicles and whole system of manufacturing cars and a whole industry for parts, repair, maintenance in the billions, thinking seriously of changing it all to EV would have seemed crazy... until Elon Musk's Tesla began his pioneering innovative enterprise from scratch!
I think without Tesla and its successful launching of EVs, no one was taking it seriously. And the challenge huge and too costly given their whole systems and foundation was on manufacturing ICE cars and the traditional ways of established methods of operation.
