How to disassemble an MGZS EV battery

I came across this whilst searching for something completely different!
Not something most of us is likely to be doing but very interesting all the same.
The presenter hasn't done a very good risk assessment so don't assume his safety precautions are anywhere near adequate.

The only problem working on BEV batteries is they're very heavy.

Thanks for sharing!

I was a little disappointed that he didn't open one of the 18 modules (must contain 6 cells, 18 x 6 = 108 cells total). It looks like at least some of the module cases are actually metal!

I don't get why every second module is painted a different colour.

It's a little scary that there is no mid pack disconnect. And at 450 V, the pack is at the upper end of the sub-800 V pack voltages.

Edit: Also, where he said was the half-way point in the pack (bottom right in the "from above" view) was actually 2/3 through the pack, hence the ~285 V reading. Half way is actually at the bottom left of the "from above" view, at the far end from the connector and BMS. "Close enough" he said

Is this the guy who has bought two accident damaged ZS EV's and is effectively making one good car out two ??.
If so, I have been watching his progress - interesting !.

It looked undamaged? So why's he set about it?

I have remember watching these videos' ....... ????????

Let me take a look for them and will get back to you, if I can find them

Here you go !.
A accident damaged white ZS EV and a blue ZS EV are used to form the fix.
Not really a full "cut n shut" as we know it.

Not really just nickking parts from one to fix the other the old cut and shut was 2 halfs weld together that said you can cut out a corner and weld together best practice is to pick a existing seam
