MG4 Not fully charging

[andrewhs]

I have had an MG 4 trophy for two years zappi charger and octopus electricity supply . recently it will not fully charge ie adding approx 5 khw then stopping . Octopus and Zappi cannot find any faults , I have tried charging the car away from home and it works fine

Has anyone experienced anything similar ? or any thoughts on a fix

Have you charged away from home using a 7kW AC charge point?

Hi, is that using IOG and is it the same when you select 'fast' charge on the Zappi?

no i havent

I suggest you do so, to rule in/out your Zappi as being the problem. (Charging away from home on a DC rapid charger doesn't rule out your car as being the problem, as a DC charge bypasses most of the CCU that is used for AC charging).

PS - where in South Scotland are you? If you're anywhere near me you're welcome to use my home charge point as a test.

At about exactly the same time as yourself I posted on the , Minor CCU connection problem , post, something similar.

Have you tried using the granny charger?

Have you tried using the granny charger?

tried the granny charger yesterday and it charged from 75 to 90 % no problem , so i am thinking its an issue with the zappi

If you haven't done so already double check the settings in the Zappi app also switch the Zappi off at the main fuse board for a couple of minutes before reconnecting so it reboots and installs any pending software updates.

There is a helpful Zappi forum myenergi

Best approach is to check for longer periods:

1. Will it take >50% charge increase on another AC charger?

2. Will it take >50% charge increase on granny charger?

3. Will it take >50% charge increase on Rapid DC charger?

If (1) and (2) fail and (3) works, you probably have a CCU failure (which happened to me) or other fault in the charging system. If it works on other AC chargers then it is probably your Zappi at fault.

The CCU fault develops over a few weeks, it starts as an occasional failure to charge fully on AC, then it happens more and more often until it won't even charge for 10 minutes without stopping.
