Ranger rover 14.7kwh pack bms

Post by pemtek »

Has anyone got the Samsung bms working for the rangerover packs?

They are 12s 37Ah and there are 9 of them.

I am not sure if the bus to the modules is can bus, the lines from the controller seem to be isolated using some transformers. You can see them on the bottom left of the square pcb photo. There is also no can transceiver chip on the individual bms boards that I can see.

I will have to get a scope out and try to see what is going on.

The Samsung SDI BMU panel has the MAX17841 driver chip, while the Jaguar / Range Rover battery has the MAX17823B BMS chip. In principle, they can talk to each other - but of course the factory software is not suitable for this.

OK thanks for that. Pity they didn't just stick to can bus.

Found this - viewtopic.php?f=26&t=1179

Now I am happy.

Thanks again for the info, because of the conformal coating on the chips it is almost impossible to read the text so you helped alot.
