Hi All,
I bought burned battery pack (14.5kWh) for my c-zero 2016. I have already all new cells but BMU (see the picture) seems completely damaged. I checked BMU from other working battery pack and everything works.
Could anyone help to find new module ?
I will be greatful for any information.

Wow Tom, you're rebuilding that box of cinders? I'll be replacing my battery pack in about 3000 miles with a salvage pack, but want to keep the spares for long-term maintenance. Have you exhausted the salvage yards in your area?

Unfortunately we don't have too many salvage places with electric cars (Poland). Even it's not easy to buy used whole battery pack 14.5 kWh. Readily I would buy it. I have good working cells and would be nice to get only managment for them.

Hi,

That is an interesting component - if that were a 16Kwh battery pack then the circuit board in that location is a ground fault indicator circuit. I'm not totally sure if it does the same job in a 14.5Kwh battery pack as it looks a bit different but most likely it is the same thing.

it is worth contacting Pro-LOX in the Netherlands, he strips down battery packs so he'll have those kind of components.

Thanks,

Gary.
