Also, Volt components have specific ID codes that are checked each time the car is turned on. If you even attempt to substitute a different charger in place of the original one, the car will not charge or operate until the main ECU is re programmed at a dealer to recognize the new component.
So you are are going to have a lot of serious obstacles to your project. (not saying it can't be done, just that you will have major headaches trying to get it to work without cooperation from GM)
