charging rate difference

[rav]

mg zs ev trophy long range charging with ohme pro, whenever I charge, ohme shows charging at 7.18kwh but car only charging at 6.4kwh as per ismart app, where the rest of energy going, being charged for 7.18 by octopus ? Thanks

so the charger shows what's leaving the grid, the car shows what's going into the battery.

The car has to convert the AC to DC to charge the battery, run whatever is live in the car, I think it's also charging the 12v battery. So I guess the answer is into the car and a bit of heat, produced by inefficiencies.

Thanks but my kia e-niro shows charging at exactly same rate the charger supplies, it's only this mg zs ev?

I've no idea about the Niro, but what it reports can't be what's going into the battery, maybe it's reporting what's arriving at it's plug?????

My EV3 in the Kia app shows less than the Octopus/Ohme app due to losses. Not just an MG thing
