Battery Heater

[Ukchris]

Hi all, hope you have all been getting MORE positive results from mg regarding delivery dates. The reason I came on is now that it is getting cooler I was wondering if there is any benefit from using the battery heater at any particular time, I would be grateful if you could advise me on this matter.

From what I have read on here, pre-heating the battery prior to rapid charging is beneficial.

But be aware that it only comes on if the battery (or maybe the ambient) temperature is under 10°C. And yes, the idea is to turn it on before getting to a rapid charger.

MG ZS EV Long Range - Rapid Charging Test - 76kW Peak?

Speed seems to bomb out at around 85% SOC on the graph, so I guess 85% is the optimal cut off. (y) Yes. At around 83% SOC the charge rate dropped to 27kW. I would stop a Rapid Charge when it gets to this point unless you really need the extra range and are not holding up anyone else who wants...

Is this an option in the infotainment system and/or app?

Yes I think I’ve seen an option in the screen allowing battery pre heating presumably for charging.

Is the battery heating only for use before you do any charging. Or on a cold day, say an hour before you go out, can you plug in your in home charger and turn on battery heating. Will this heat the battery up so you have a longer range when you leave and go on your journey. Will the power for the pre heating of the battery come from the plugged in charger ?

Wouldn't it be nice if the battery temp was displayed on one of the screen so we would know if the battery heating was required. Just a thought.

Yes, yes and not exactly.
Power to heat the battery will come from the battery itself. If you are plugged in and not outside of a scheduled charge period the charger will replenish the battery at the same time, but depending on how much power the heater draws (which I don't know) it may be at a slower rate.

I read somewhere, the optimum temperature the battery operates at is around or just over 20 deg C, so if the ambient air temperature is less than that then you could apply heating if required.
