I am wondering if this can be heat related and the car is slowing down or stopping the charging when its battery gets too hot. On my PacHy the cooling fan will come on periodically when being charged from my home ChargePoint in order to cool the battery down. During a full charge cycle from 0% to 100% this happens two or three times, or twice that often if the weather is hot or if the engine is hot from having been recently driven on gas. I am wondering if there is something wrong with the cooling fan such that it fails to turn on, thereby causing the battery to overheat.
