Iwọn apo batiri ti dinku, lati bii 10.6 cu ft (300 L) ni iwọn didun ni EV1, si 3.5 cu ft (100 L) ni Volt. Igbakeji Alaga General Motors Robert Lutz sọ pe ọkọ ayọkẹlẹ ere idaraya ẹlẹsẹ meji ti o ni idagbasoke nipasẹ Tesla, Tesla Roadster (2008), ati ilọsiwaju iyara ti imọ-ẹrọ batiri lithium-ion ṣe iwuri fun u lati tẹ awọn ọkọ ayọkẹlẹ lati dagbasoke Volt lẹhin 2006 Detroit Auto Show, bori atako inu. Lutz's initial idea was to develop an all-electric car, but Jon Lauckner, General Motors Vice President for Global Vehicle Development, convinced him that to avoid an expensive battery, range anxiety concerns, and lack of public charging infrastructure, they could use a smaller battery pack with a small petrol engine driving a generator acting as a backup to extend the range, but without a mechanical connection between the petrol engine and the drive wheels, so it would be a pure electrically driven vehicle without many of the limitations General Motors learned from the EV1 experience.
