Hi.

I have an EQA with a PodPoint home charger. Sometimes the car won’t accept a charge from the PodPoint charger, but will when I plug the car into the normal 3 pin plug charger.

there doesn’t seem to be any consistency as to when it does and doesn’t work. PodPoint have run a diagnostic check and say the unit is working as it should.

Anyone got any ideas?

thanks

Try a public charge point that is AC, not CCS, to see if your EQA is accepting charge from other AC power sources. I suspect the PodPoint might have scheduling turned on or something?

Hi did you get to the bottom of the problem? I have just taken delivery of my EQA and have the same problem- can charge from normal domestic plug but trips straight out as soon as i try to use a rapid charge point

I took delivery of my EQA350 4matic two weeks ago and had only done short journeys in it until yesterday. Charging at home (BP Pulse wallbox) had been no problem for the first 164 miles of ownership but having completed a 190 mile round trip this morning I got home with 12% charge remaining so immediately put the car on charge - all seemed as normal, so I closed the garage door. One minute later, my MMe phone app told me that there was a charging error and it had stopped charging. I tried a few times more without success to get it to charge for more than one minute, but failed, so I called MB Roadside Assistance who advised that they would send out a MB specialist (who duly arrived 5 hours later!). In the meanwhile, about 1.5 hours after leaving the car not charging but still plugged into the wallbox, my phone bleeped and told me that the charging had commenced. I did let MB Roadside Assistance know but they said they would not cancel the callout so it could be checked. The MB specialist told me that the battery cannot accept charge when it is too hot or too cold - and mine would have been very hot having just done 88 miles on the motorway. Apparently you can pre-prepare the battery for charging by telling it to heat or cool before arrival at a charging station - he wasn't sure exactly what I had to do to set this up but it is in the navigation system within MBUX - he suggested that I read the owners manual and it must be in there. I wish I had known this, but I wonder if it is what was causing your problem?

Did it get fixed? I have the same issue with an Ohme charger at home and the podpoint charger at work

This thread interests me too. I have an EQA250, which I have been able to charge at home with the standard Mercedes mains 'charger' without any problems - other than the slow rate of charge.

A couple of months ago I had a 16 kW solar system and ZJBeny wallbox-type charger installed at home. Charging with the Beny unit has proven very much hit and miss and my solar installer is continuing to try to resolve the issues, but I understand that support (for my supplier) is minimal at best.

I always charge the car at least 12 hours after the most recent journey and I've tried both scheduled charging and 'plug and play' - and various charging rates from 32 amps down to 6 amps. I have experienced the occasional successful charging session, but more often than not it drops out, sometimes after an hour or more, sometimes, quite quickly: there's no consistent pattern.

I have never - in nearly 5,000 km - used a public charger.

Just for comparison with EQC, which I would have expected to have similar charging protocol implementation, I haven't yet thankfully had any immediately insurmountable problem generally with charging in 3 years of ownership except the odd broken DC charger. Neither have I ever concerned myself with battery temperature. It just all works consistently amazingly well. I use a EO mini ac charger but haven't used podpoint or beny or ohme brands so maybe their protocol implementation is slightly unexpected for the car? It might be worth trying the EO brand or ac public charger or Mercedes brand charger or checking for car firmware updates with Mercedes dealer and also checking for updates for the charger software, and also trying a different cable

Update on my post above (#6): Last week my solar installer returned to fit the 'solar' version of the Beny Dynamic Load Balancer ('DLB') - the Beny 'charger' was supplied with the standard DLB - in the hope that that would resolve my charger drop-outs. We determined immediately that it didn't resolve the issue.

Next step: my installer phoned Beny technical support (in China) and the call was answered by a knowledgeable English-speaking technician. The result: my installer needs to slightly reconfigure our switchboard wiring, which, I understand, is simple, but time-consuming, so he's coming back this week to make those changes (all at no cost).

In the meantime, we disabled the DLB in the Beny App (simple process) and although I've only charged the car once since doing so, the 'charger' worked faultlessly.

Sorry for slow response, I've been away. I haven't had a repeat of that exact problem but my "home charging" setting reset from stopping at 80% to 100% which was annoying, and I couldn't seem to get it back, so I did completely reinstall both the wall box's software and MMe on my phone which wiped all the "special" timer programs etc. and ever since it has behaved perfectly...

Do you have an Ohme box or something different?

No, I have a BP ChargeMaster - also known as BP Pulse - it was part of a deal from MB when I bought my A250e hybrid at the beginning of 2021 (which I chopped in for the EQA350 when hybrids no longer were free in the London congestion zone). The BP box is not very sophisticated and didn't get great review, but it was free, so I took it!
