How many volts does a 72 volt battery have when it is empty
240KW/400KW industrial rooftop - commercial rooftop - home rooftop, solar power generation system.
Yes as others have stated the 2017 Volt''s battery pack is 18.4KWh total with 14KWh usable (for EV operation). Keep in mind that does NOT mean that the other 4.4KWh are totally unused. The Volt also reserves a buffer for hybrid vehicle operation (charge sustain mode). This buffer is likely close to ~1KWh. Also the Volt has a "turtle mode".
