Hello,
Can someone explain to me why it takes 11hours+ to charge my BMW i3s (120Ah) on the Source London network?
I realise that the i3s is limited to charge at 7kw, rather than the possible 22kw, but surely then it should charge in less than 5 hours.

Appreciate any explanation for this. Thanks in advance.

It is limited to charging at 11kW on a 22kW charger, so you need to check that your charge settings in iDrive are set to maximum...
This is only possible using the heavy 3 phase cable, so your stated 7kW if you are using a 32A cable would be max...

Ok thank you. When I look online it states the phase 3 cable is only suitable for the 94Ah BMW i3.
I will look at the car settings.

Thanks for your help.

I take it you know about the 11 hour cap, don't you? If you charge from 8pm to 7am, you only pay for 4 hours. Using that with slower charging, might actually be better for battery health, as it won't be sitting at full charge for so long.
