Hi great project, im wondering have you made any progress with this. any chance someone has a wiring diagram for the connections on the battery ?

i recently purchased a golf GTE battery and would like to power up the contractors and measure the voltage via the can before dismantling it.

Thanks Alan.

If you could send me the pin out off the connector that would be really helpful.

I have received vehicle HV training so hopefully wont zap myself, i wasn't aware the internal can bus could activate the contractors.

from what i know the battery has to receive an external 12v single and the safety ring circuit to allow activation of contractors.

Thanks Alan i received your email. great job on the diagnostic screen, im going to try connecting with my Vcds to the external canbus and see if i get any responses from the controller.

i have decided to open up the pack and take a look inside. that was a good long struggle. if anyone has any good suggestion on how to remove the silicone sealer in the future that would be very handy.

i did try cut away at most of it but not knowing how close the components where to the edge of the case i didn't want to risk it.

i was surprised to see how small the batterys where inside the pack i will add some measurements soon if anyone is interested.

here are some pics of inside the pack.

hi all i managed to connect to the battery via the powertrain canbus. its module 8C which isnt listed on the standard list.

annoyingly if you are connecting you have have to use the new hex-net interface otherwise you wont be able to view alot of information.

big thanks to alan for sharing the pinout. i found it to be very similar to the e-golf / e-up which has helped to identify the remaining pins. i will place the table up once its completed.

from what i read if there is no errors the contractors will switch on with the ignition signal. if that is the case i will then monitor the internal canbus to see what is sent and try identify the activation signal.
