The obvious solution would be for the manufacturers to make their onboard chargers/inverters bidirectional. The problem of the auto industry, utilities, and governments working cooperatively has made this impossible to date. We can always hope. Several manufacturers claim they will have 120 v, and 240 volt outlets in their pickup trucks for running tools.wouldn't it be great if I could tap into the 60 kWh propulsion battery? A modest 3-4 kW's could effectively replace a Fossil Fuel and noisy generator. At the very least, I would like a way to recharge the twelve volt battery with an ignition switched supply.
There is no simple/safe way to DIY tap directly into the traction pack with an inverter. There are relays inside the battery box which isolate the pack from the outgoing power cables when the car is powered down.
I think I recall somebody mentioning that one of the Korean EV makers does allow jumping the 12 volt from the traction battery. Anybody?
