MG4 Home Charging Issues

[Rob875]

My MG4 SE LR has done 35,000 miles and I usually charge at home using a ProjectEV 7kW charger in dumb mode. I set the timer in the car to charge between midnight and 7am to take advantage of my Economy 7 rate, normally charging to 80%. On locking the car I check through the window that the display is showing "Charging Scheduled".

On a few occasions I have thought the car started charging immediately after setting the scheduled charging, i.e. several hours early and on peak rate electricity, but I was not sure that this had actually happened. Today I have had a smart electricity meter fitted, and plugged the charger in on a scheduled midnight charge to check that the charger was still working working OK with the new meter connections. Despite seeing the "Charging Scheduled" message on the dash, and checking the timer was set with a midnight start time, the car started charging immediately. I then unplugged, reconnected, and then all was OK, with the car showing "Charging Scheduled", but not yet charging.

Has anyone else seen this premature charging issue?

Are you setting the charging times on both the car and on your wall charger?

You only need to set it on one or the other but not both.

I never set charging times on the charger as Project EV were never able to get the charger app working for me

I've charged mine in a similar way at home for over 19 months and never had a premature charging start.

I just double check that scheduled charging is set, as sometimes it isn't after being at relatives' houses with Intelligent EVSE, when I disable scheduling as their EVSE controls start and end.

My own home EVSE is a 6 year old dumb 7kw with no app.

It's just happened again. The car is set to start charging at midnight. I plugged the cable into the charger, then into the car, then locked the car, the display showed "Charging Scheduled", but my new smart meter showed a draw of 7.5kW.

I unlocked the car, which stopped the charging, checked the settings were correct, got out and locked it, and it now is not charging, but it will now start at midnight.

This is very strange.

I'm struggling to see the difference between what you did the first time and the second time.

What time is your charge scheduled to occur between?

Midnight to 7.00am - I have economy 7

It's difficult to know if it's the charger or the car that's causing the problem. Can you try on someone else's charger?
