That's precisely what I think is happening. The ChargePoint unit is lowering the pilot during the pause, causing the car to resume charging at a reduced rate.

It must be only certain ChargePoint units as I've never experienced anything like this and I frequently use their chargers.

Or maybe your battery is in a state where the BMS doesn't decide to do the pause.

Oops! :oops: That is indeed a pause, which I should have checked for.

I still wonder if it could be charrger firmware related though. [ Edit: for example, your charrger seems to be capable of brief periods of more than 3 kW, whereas kevin1956murray's doesn't seem to do that. ]

My mistake that's not actually a ChargePoint charger, it's a company that has a partnership with them and you can use your Chargepoint card to start a session. I only see such spikes with their chargers.

Here's an actual Chargepoint charge session from a dual head charger.
