I rarely get to drive our (my wifes) ZS in the dark, so have just been out on some quiet back roads where it's not lit up, and I can see the brake light coming on :) I tried a few different things to try to identify what triggers it exactly, it looks like it is down to it sensing a certain rate...

If you have an obd2 dongle and an app that records it such as ev watchdog, you can see how much energy has been regenerated and how much has been used from the battery. It found it very surprising how much energy was gained from regen in normal everyday driving, I thought it’d be a tiny amount...

Be careful using the energy used by your home charger in certain calculations, the onboard AC-DC converter loses something like 10% in conversion. So you calculation isn't valid: Using 3.2miles/kWh, Real-world range = 42.5 * 3.2 = 136miles. To further complicate things! Regen is included in the...

FYI, have a read here: https://www.mgevs.com/threads/discussions-on-using-ohme-charger-with-the-zs-ev.2334/

I’ve just read the 5 is getting a recall to resolve the issue that the brake lights do not illuminate when the regen causes the car to decelerate past a certain threshold - as specified by law. Anyone heard about the ZS getting a recall too to fix this? It is something that worries me when...

LOL, checking the crash avoidance on a test drive

Agreed, it does it if it's pretty cold too. Regen can pump some 100+ amps / 45+kW into the battery, so it needs to be warm enough to ensure it can handle that kind of power (a bit like when charging on a rapid, it won't go as quick if it isn't warm enough)

I'm not saying you're wrong, but it's never been a reported issue on this forum with the MG. I have no idea about other EVs, but the MG tells you to do an AC charge/rebalance once the imbalance caused by DC charging reaches a set threshold. It is not that uncommon for folk on here using mainly...

I'm not sure that is correct. Yes rapid chargers aren't great for the battery compared to AC chargers, but it's not that bad and I've never heard anyone on the forum here ever say it has caused their imbalance to become so bad that it's taken weeks of AC charging to rebalance them. Only the bad...

The guy was making a joke about not having an app because of the world-wide main media coverage yesterday of Teslas app issues locking folk out of their cars. To clarify though for anyone that doesn't know what happened. Teslas can be unlocked etc using a phone/app instead of having the "key"...

I think you're going about this the wrong way, your car clearly has issues and isn't working correctly. I would suggest you take it back to the dealer and give them 1 chance to fix it or, demand your money back or a new car.

Interesting. I’m guilty of forgetting there will be folks without a driveway for charging. It is/will be much more difficult for them. I wouldn’t buy an EV currently if I didn’t have home charging, not until the infrastructure gets better. I’m not sure if/when cars will come as standard with...

448V is ok. New BMS as Kithmo said. We always say, reset your trips, then the range GOM shown (157 in your example) will be relative to WLTP & comparable.

That's the chap, JW :)

OMG! Did you "discuss" it further with them, maybe they don't understand....

Can you take it to another dealership. I don't know where you are location wise etc, but everyone would recommend Chorleys. I'd try giving them a call and explaining your situation and ask if they would do it, if so a day trip out to take it there.

Well spotted, that’s a good photo to share for folks. There’s a very very good YouTube video series by a very posh sounding electrical engineer who explains all the home regs and how to test them all. One video is about EV earthing, and it’s interesting in how no earth solution really fully...

I don't think we've ever ascertained exactly what the criteria is that triggers the car to warn to slow charge (balance). The very latest BMS has been around for well over 6 months now, so I'd say it is a safe update. The voltage change does not affect the range as it "just" shifts the usable...

I didn't look at the literature that came with it. I studied the official UK/England wiring regulations in regard to what is required for a permanent electric car charging. There's a few websites which document commando based EV charging requirements too. As I've completely re-wired my entire...

60mV imbalance does seem high given you're balancing it regularly. 9 minutes balancing time would mean it's not doing much if any balancing at all, given it takes something like an hour to balance 0.01V. I'd guess it is to do with your BMS version, maybe you should consider getting it updated...
