Has anyone ever taken one of these batteries apart? They are the common PSA/Vauxhall/Toyota van line batteries. Their prices have started to come down rapidly.
They exist in 50kWh and 75kWh versions and prices seem to be good here in the UK

What's the price of a 75kwh?
And do you know it's configuration?

Hi Tom,
I've taken apart a 75kWh battery. It is made of 27 modules with a 4S3P configuration for 108S. The cells are from CATL. I've attached some pictures.
The BMS is based on MAX17823B, with nine BMS PSCB in a 12S configuration.
Despite the 50kWh battery, where each module has a BMS with a 75kWh battery, only nine modules have a BMS PCB. Other modules are connected to these with BMS.
The blue module is with BMS, and two grey modules are connected to the blue one.

The 12S BMS PCB.

Ah cool just like the Egolf approach
Thank you for the pictures, you ever have a 50kWh apart?

I have not personally taken apart a 50kWh battery, but I'm familiar with the modules inside.
I've been using them for energy storage projects. They are 6S2P configuration, CATL cells, 2.74kWh, each with BMS PCB based on MAX17823B. Some of the latest batteries use the newer MAX17854.
Here are some info on these batteries:

A lot of pictures:

AFAIK these batteries are glued, which makes opening them a bit hard.

Interesting; it should be compatible with our MAX BMS
6S2P
6S1P
12S1P

Friendly warning.
Do not mix up order of master-slave modules as you going to burn down master (blue) module bms resistors or even max IC. I've Done that.

Does anyone know what order the batteries modules are in
I have a dodgy temperature sensor on one of them (52) that keeps giving me traction error and had enough of Vauxhalls who cannot and won’t fix it so gonna have to do it myself and change the dodgy module
Either that or replace the whole battery myself with one from a written off vehicle

Does the
Master look the same then and is that the first one on the sting
I thought by reading that the main control box was the master bms ?

How hard is it getting the lid off of this please
And what’s the easiest way heat ?
