Morning All,

The cable I use to charge the car won’t charge any higher than 6amps.
According to the instructions if you press button you can cycle between 6 or 8amps. Pressing does nothing,it stays stuck at 6amps.
It’s plugged into a 10amp socket. 8amps was working up till about 6 weeks ago.
Anyone have any thoughts as to what could be the issue?
Cheers
J

Either issue with the house supply, the charger box, or the car charging hardware.

Usually by process of elimation for someone lay like me. Maybe others have better tips.

When I had the same issue it was the house voltage too low.

Unlikely to be the car or the house. it's probably the charger

if you can try it on a different car to see but looking it, it it seems well used.

In many jurisdiction for chargers that are designed to go over 8 amps it in mandatory s to have a temperature sensor to detect if the 3 pin plug is overheating (many sub 8-amp charges retain this feature since they are often designed do 16 amps, but are software limited to 6/8 amps). When the temperature sensor fails, they revert to 6 amps for safety. Some brands with LCD screens will show an over-temp warning when this happens. (this happened on my Charge-amps EVSE).

Is that a Teison? One of those came with my upgraded Leaf. Couldn't stand it and binned it after about 2 days. The instructions explained the circuit design in great detail over pages and pages, but they forgot to explain what the one button on the thing did (I assumed it was for 6/8 amps selection, or maybe to change the lcd display?). The limited instructions it did have, didn't work and seemed to be for a different software version. Maybe the button on mine was dead from the factory and maybe the button on yours has just died?

The charger is part of the car. The external brick and lead is an EVSE not a charger. The combination of EVSE and onboard charger determine the charging current. The EVSE tells the car the maximum available and the car decides how much to draw up to that maximum.

To check it is not the car, plug it into another EVSE; a public AC one at a carpark or whatever, and see what curent you get then. That will give you a good idea as to car or EVSE being the issue.

blah blah blah, everyone calls it a charger, and you knew exactly what I meant.

Yes, I knew what you meant, but what I knew is irrelevant, the OP may not have known and the thread is to try and help them diagnose the problem they face. There's no need to be rude to me for trying to help.

On mine (PHEV)....I have to press the button to up it to 8amps before I plug it into the car.

given the thread title is literally PHEV Charger Issue

yes technically they are called EVSE but everyone, the sellers of the cables, wall boxes etc, the companies that do the DC fast chargers all call them chargers.

Or of course try another car on your EVSE if you know somebody local. Forgot the obvious!
