Hey guys, question for you. Is there a way to isolate a HV powered item from the HV system? I want it to get power from the HV line but I dont want the vehicle's sensitive computers to know its there.

That probably sounds confusing but Ill try to confuse you even more by attempting to better explain it lol

Production EV's computer systems run isolation tests. I have a Tesla battery fluid heater getting power from the HV line of the car. The car didnt like that and threw an isolation fault code.

So is there a product I can buy or some way to isolate the Tesla heater so it gets power but is some how not recognized by the car?
