Struggling a bit with the EO charger and now a flat 12 volt battery

[mj224]

Elsewhere on this site, I have been moaning about an EO charger that seems to be duff.

Last night, the Charger switched on as per schedule, but did not charge. This morning, the 12 volt was flat enough not to switch on the car. I imagine that the charger switched on the 12V circuits, which then drained it.

So, this morning I charged up the battery with the 12V car charger. That seemed to sort the problem. But later in the day, 30 miles away, and three hours parked, the 12V battery signal said it was very low and I should start the car. Fortunately, the car did start.

I drove to a rapid charger and did an 85% charge. Having arrived home, I continued to charge the 12V battery. The volt meter for what its worth, says the 12V battery is 13 volts when driving, and 12,5 when stationary for a while.

I am wondering if the 12V battery is duff, which might be causing the charging problems..................

I am about to replace the charger, but it would be cruel if the problem is the 12V battery.......

All pointing to the 12V battery. For £100ish, change it for peace of mind

as soon as I read some of the 12V horror stories, I got one, not this model but similar...

Thanks for replies. I have charged the battery a couple of times now. I think the draining of it the other night has damaged it. It seems to hold its charge for a while, but after a run, the warnings come up again.

I am wondering whether the traction battery is charging it.

Anyway, back to Panda Motors on Thursday, and I will ask them to check out the problem, and change the battery if necessary.......

I am wondering whether the traction battery is charging it.

It does that when in ready mode or charging, via the DC-DC converter.

You can tell by the battery voltage going to about 14V soon after going to ready mode.

I would suggest a 12V battery monitor - very useful to check these things. Early on I charged with an old V1 Zappi on my travels and noticed that it drained the 12V after finishing a charge. It hasn't happened since on other chargers (or with any updates the dealer has applied).
