In actuality, that's exactly what's happening - Nothing 'runs off the 12 volt battery' while you're driving the car. It's just there to get it started. The DC to DC converter is quite robust (capable of 70 amps output, IIRC) and it can and does power every 12 volt accessory with plenty left over to recharge the 12 volt battery if it's ever in need of a chargeed5000 wrote:That would be great if they could find a dc to dc converter robust enough to power all the controls and accessories without a lead acid battery. Obviously it would have to be powered up from the traction battery 24/7.
