My car has started reducing the charge rate on AC charging. It starts fine at 32A but after a little time (usually 5-10 mins), it drops back to 12A and stays there. I can see from the app that the charger is still advertising 32A (i.e. it displays 12/32). If I look at the car’s screen after the drop has happened, I can see this:
It’s obvious that the car thinks there’s a voltage drop, but I’ve swapped cables with no change in behaviour and have also charged another EV (ID3) on the same charge point and it works without issue. The supply here does show a decent voltage drop when pulling a lot of power (typically 240V down to 222V) but I’ve been charging for almost 18 months without significant problems (although I often see short periods of reduced rate overnight, but it’s usually down to 24A and for a short period only).
Ideas?
