I wonder if you can run the charger while car is motion.
You could make a pack of say four 16000 mAh li-po packs and run the charger/pack from the trunk. Battery weight is 1290g (2.85 lbs) and around $80 us each. 10c discharge on 4 packs would be over 600 amp capability
So 64000 mAh pack @ 16 volts = 12 pounds. Maybe 5-10 pounds for an 12v to 110 inverter. You could charge this pack up while at work with a 110 volt charger.
Also how are the accessories run, 12 vol motors or higher off the main pack as the accessory pack could help run fans etc and save on keeping the 12 v battery charged(does it have one)
Volts have a normal 12V AGM battery mounted in the trunk. It's charged as needed from the 360V main battery, including when the car is plugged in. All accessories and the computers are run from the 12V AGM with the exception of the resistance heaters, A/C compressor and starter (IIRC). Since 12V charging of a 360V battery is a lossful and non-trivial task, extra 12V storage capacity is of limited usefulness.

In normal weather, with the car turned on but accessories and climate control off, the base load is around 300-350W, btw.
