Got a second pack now to play with.
This is the external connector pin out as far as I've worked out.
I've been replaying some can logs at it taken during charging but haven't been able to get it to close the contactors so far. My main aim is to find the balance command if I can.

EDIT
I've managed to get the pack to close the contactors from the external can interface, the Hybrid Can (pins 13 & 14) IDS 0x09C & 0x3A6, if either stop the contactors open.

Hi,

Do you guys know what is the correct voltage for those lithium polymer cells from the golf gte?

Ive read that they are Lithium nickel manganese cobalt (NMC). And from what i've found they have a 3.7 V nominal voltage with a 4.2 V maximum while charging. This is correct?

Thanks.

Hi,
I bought a VW Golf GTE battery and have been investigating the best way to communicate with the battery via the external plug (without opening the battery).
Any suggestions on what is the best way to communicate?
Is it possible through VCDS to get the voltages from the battery through the external plug?

Thanks
