Hello Drive a 330e and want to charge it at work. Unfortunately, I would have to pull an extension cable from a socket about 8 to 10 meters long. I would use the weather-resistant PUR 1.5 mm2 cable. I would put the BMW charger under the car in rain and connect it under the car with the PUR cable. Does the plan work like this? On the BMW charging cable it says that you cannot use an extension cable. Don’t really see the point in it. Whether wires in the wall or in the Ka bel comes out on the same. By the way, always load on the lowest 6A level. Thanks Gruss
