Not at all well. For obvious reasons, dc charging at hundreds of volts is blocked by safeties. Hooking the 12v together could work to charge the dead 12v but doesn't charge the hv battery. You could plug in a charger to a 2kw inverter. Fastest way by far is a tow. Use regenerative braking on dead car and it charges fast. Something like 10km of range for every km towed.Can you "Siphon" from one EV to another with the equivalent of EV jumper cables?
