Hello
I know I'm annoying, but you still did not answer my question, Im looking at shematic of 2018 leaf ptc system, and I cannot see any wires that could tell ptc heater how much heat we need so the level of power must be controlled by a power transistor inside battery??
But that is strange?
Please help

Best regards
