A friend is quite interested in Chevy Bolt, but has only a 30A dryer outlet and a 15A 120V outlet available for charging in his rented garage. Chevrolet website gives no useful info about charging. Local Chevy dealership people are all clueless, even the service and parts departments Aerovironment 30A EVSE demands NEMA 6-50. costs $540 to $750 Jukebox 40A demands NEMA 14-50 (not a good idea on a 30A circuit.) cost $550 to $600 What would he need to charge off his 30A 240V circuit (not sure whether 10-30 or 14-30)? Apparently, the Bolt has no onboard charger, so can't be plugged directly into any 240V outlet.
