Automobile - All Electric batteries question
 

Need expert to answer how many watts and/or kw's it takes to operate an all electric automobile?

My I suggest that you go to the various existing websites for EV manufacturers. They will typically list the vehicle weight, the electrical HP, the battery capacity in Kwh, the estimated range etc., this will get you some basis information. If you are looking for this information to convert an existing vehicle, I would suggest a Google search. I have seen many conversion article, a lot of these used small trucks due to the weight of the batteries, as I recall Chevy S-10 were a popular choise.
Hope this helps.
