I can answer this part (only). LEDs are very much polarity sensitive; polarity should be marked on the LED "tape". The wire taps will be positive; car chassis will be negative.

Well, there's that too! :oops: Though you can probably start V2L from "on" mode, I suspect; the contactors would then come on, but it technically would not be "ready" mode, so you would not be able to change out of park "gear", thereby being a tiny bit safer. I assume that the DC-DC would...

Swelling massively is quite scary in a battery, unless it happens gradually over months. It occurred to me that the other reason to get a decent, known-brand jump starter is that these things will have LiPo batteries in them, to be able to crank starter motors. LiPo batteries (Lithium Polymer...

Yeah, the MPPT want's to get the best power transfer from what it assumes is a string of solar panels. It's really not the right equipment for this job. Interesting that you got it to work at all though. It may be possible to patch the inverter's solar charge firmware to take a fixed power from...

True, but even if there is a small deficit (net auxiliary battery drain), it should extend the run time quite significantly. Probably plenty to keep running all night, for example.

My guess is that they use 2 half-bridges to generate single phase alternating voltage. To generate 3-phase output is easy with three half-bridges, but then you don't have a neutral. I think you'd need a fourth half-bridge to generate the neutral. Since 99% of V2L applications would be single...

As far as I know, that's not possible. Could there be a measurement error? Maybe there is inductive coupling involved. But it still makes no sense. It all makes sense (single phase output) except the last measurement. It should be 0V L2 to L3. Edit: Oh, wait. Some of it could work out. L2 and...

Those are the software (maybe firmware) versions for the infotainment system. They are the ones most likely to be region dependent, and hopefully can be updated over the air. There are about 20 other firmwares in the car, which can be accessed via the unofficial Thai app. See the resources...

It certainly listens to CP (the Control Pilot) when charging. I think that pulling CP down to zero volts with respect to Protective Earth helps convince the charging computer that this type 2 plug insertion is not for charging.

There is no standard for this (as yet), so SAIC are free to require whatever network of components there that they choose. I suspect that they thought that by choosing their own resistor value, they'd be able to sell an MG branded cable at a nice mark-up, and drivers would have no choice other...

Yes.

I don't believe it would be in danger of overheating, it would just run the coolant pump a little more, reducing charging efficiency a little. Though the radiator for the on-board charger might be under the foam too.

But won't it melt because of the hot exhaust? ;) Seriously though, the air conditioner's condenser could get pretty hot in summer. It's an intriguing idea though.

Standard pitch for M8 is 1.25 mm. Fine M8 thread pitch is 1.0 mm. Edit: As per for example Bolt Depot - Common Metric Thread Pitches - Standard, Fine, Super Fine, JIS

I'm rather taken with this one, despite the next poster's opinion: https://www.mgevs.com/threads/top-accessories.1023/post-11657

14 V on a nominally 12 V battery is a kind of "surface charge"; it won't stay that high very long. Even 13.4 V is not sustainable, and it was only that high because it was being charged heavily. Most of that fall is because it was no longer being heavily charged by the car's DC-DC converter...

True, but I suspect that the intention is to only use single phase loads on one of the three outputs. Though it would have made more sense to then only enable one output.

Perhaps a software update one day will save the hapless neutral.

You could split the load over the three outputs, thus lowering the current through the phase wires. The poor old neutral however has to take the combined current.
