Someone posted on a local MG4 FB page their experience with a V2L adapter bought from MGTitan. They were getting 160 V AC output and power output was severely limited. Had one of those stupid universal sockets to fit plugs from various countries. Piece of crap IMO.

That was the no load condition. But then I don't know what V2L adapter they used. We don't get that here, just a simple single outlet and limited to 10 A, ~2.2 kW. To get higher power output requires a custom cable unsupported by MG.

For clarity (since I was quoted), I've made no statement about this. As a general principle though (i.e. not MG or even car specific, this applies to any battery pack with multiple cells) ensuring cells do not get too far out of balance does matter for both useable capacity and for a pack's...

It is required every so often for a complete top balance. Cell capacity differences are really only evident from a full discharge/charge.

The MG4's V2L already has an E-N bond. That's why you can't use it to power a home because there must only be one spot where the E-N bond is made and homes will already have that in their main circuit board. Backup generators without the E-N link are designed for use in powering homes which...

Here's a time earlier this year when I charged to 100% overnight before a long drive. It had been 96 days since I'd done a full 100% charge. Can see the equalisation period took about 2 hours to complete: You can also see that the SOC meter hit 100% well before the battery was actually...

I have a 2023 MG4 Essence (= UK Trophy) with 64 kWh NMC battery. Last time it was charged to 80% and allowed to complete at that set upper SOC charge limit: I have power monitoring on all my home's power circuits, and the charge station used for the MG4 has its own circuit as shown above...

It's definitely doable. It's more a matter of whether one could be bothered.

Because cars with NMC battery packs will perform an equalisation at end of charge no matter the state of charge limit. It's only LFP models which require charging to 100% for equalisation to occur.

In which case the likelihood that the electrical stuff is doubly isolated is higher but frankly I do not know. I would read the specification / user / installation manual for the unit to see if it suitable for use without residual current protection. Here in Oz regulations require small...

Unlike LFP, the NMC charge voltage curve it's not so flat that it prevents the ability to do effective equalisation at a partial state of charge. There is a sufficient voltage gradient and cell voltage differential. But also importantly the deviation from a near linear voltage-SOC relationship...

The Nullarbor is not confined to WA. These are CCS2 stations, however you have to be very careful as not all of them work well. Mundrabilla for instance reports tripping off regularly when used and it shuts power off to the entire roadhouse. At others the charge speeds can be very...

We've since moved home (March this year) and so I no longer have that option as we don't have the off-grid system any more (well I do, all the components are in the shed at our new place). We have a new Sigenergy solar PV and battery system at our new place, so no real need for V2L anymore, at...

Scheduled charging implies a time limit. If the scheduled charge ends before the car reaches its max SOC setting then no, it won't have performed a balance (equalisation). If the car reaches the max SOC target before the end of the schedule, then it will commence balance (equalisation)...

The 51 and 64 kWh models each have 104 cells in series. Difference is 51 is LFP and 64 is NMC. In my 64 at the end of a charge to 80% the charge rate drops down and fluctuates between ~50-100 W indicating a period of balancing. Usually takes about 5 minutes give or take. If it's been a long...

I suspect it's because the MG's V2L is expecting to supply power to isolated loads, not to a system with a main earth - neutral link. The "L" in V2L matters. It is not designed for V2H. You'd get the same problem using a regular generator which has an internal MEN link. That would not resolve...

August update (with August 2024 shown for comparison) Not much driving this month. But it was cheap!

We bought a Dec 2022 ZS EV recently (Excite model with 49 kWh battery). It was basically "new old stock" with 5 km on the odometer. Shortly after getting it home I added it to Home Assistant. This has been the normalised range estimate and economy in the past 90 days: Varies with conditions...

A distraction...

It's been shite.
