Power Gird or Vehicle issue Limiting AC Charging - Model 3

[eilrahc152]

Hello,

I have an issue when trying to Charge at my workplace. (11kw Charger 3 Phase - 16 AMPS - Andersen)

I am getting the below error message 'Power Gird or Vehicle issue Limiting AC Charging'

I have colleagues who also have Teslas which charge at 11kw with no issue. It just seems to be my vehicle. (Not charger related)

I am under warranty and Tesla are going to do the below

AC Cable - Charge Port to HV Battery (3-Phase) (Remove & Replace) - Remove and Replace - Basic Vehicle Limited Warranty
Charge Vehicle to 100% SOC (China) - Customer Pay


Anyone had an issue like this before? Tesla seemed to think it was the chargers fault.

I'd agree its the charger's fault. I don't have much familiarity with UK HPWCs, but its my understanding that they are delivering three phases of power, presumably all with reference to a common ground wire.

248V at 16A is 3968W(essentially 4kw), and in theory three phases of that would be 12kw. Your screen is showing 8kw, meaning one phase isn't supplying any power. Since you know other Teslas are charging fine at that location it must be the cable or the onboard charger that's failed.

I agree with @Sophias_dad - it's likely that one phase of the 3 phase on-board charger has failed.

Hey Guys, thanks for your suggestions.

In case anyone is interested - Turns out it is a fault within the PCS of the car...
