Home charging problem [in the UK]


New Member

I have a Model 3 SRP and a Polar home charging unit, which is on the Economy 7 circuit. This means charging only starts at 1230 and finishes at 0730; which is fine for me. But every now and then, for no reason I can find, it doesn't charge at all. The storage heaters and the immersion heater are on the same circuit, so I know that it does come on every night. Could anyone suggest a reason why this happens? I wonder if I plug the car in too early and it somehow disengages after several hours waiting for the current to arrive.

Only thing I can think of is possibly if you accidentally set a schedule On the M3 to start charging after it would be complete.

In the US, there are no other devices allowed on a circuit used for charging a car, by code. I have no idea about codes in the UK on this, but heaters usually use a lot of current as well. I dont know if its allowed to be on the same circuit in the UK, but even if it is, I wouldnt want it to be.
