VW Golf GTE battery
Hi All,
Heres some pics of the Golf MK7 GTE hybrid battery its 8.7kw watercooled. the bms communates to the battery modules thru canbus.
if any one has a golf GTE or Audi etron near London who wouldn't mind letting me plug my diagnostic into to get the canbus control messages would be mega helpful. i would like to control the linbus controlled ac compressor.

Re: VW Golf GTE battery
Anyone has any info on VW inverter and charger wiring from Golf GTE? HV and LV connector pinout would be appreciated.
I have them sitting here not doing their thing and that frustrates me

Re: VW Golf GTE battery
I have the same pack. Documented on the wiki. There's a dbc file there for the internal battery can bus.
What's missing the the balance command, it would be great if you did manage to get a car to plug your pack in to and charge, see if we can get a log during balancing

Re: VW Golf GTE battery
Hi this is the pinout for the battery external connecter as near as i can figure.
External Pins GTE Battery and E-up
1 Can H Power
2 Can L Power
3 Airbag Crash
4 Pilot (In)
5
6 12v (30a)
7
8 IGN (15a)
9 GND
10 12v Safety (30a)
11 Pilot (out)
12 Airbag Crash
13 Can H Hybrid
14 Can L Hybrid
you need two 75ohm resistors on the pilot line to remove the safety errror

Re: VW Golf GTE battery
On the contactor control board, the left most white wire, and right moat white wire, do you have any clues as to what they are for? Maybe the safety interconnect? I butchered the cabling before checking where they go.
The 2 reds next to it are 12v in, the black can low, white can high(battery can) the next black is GND, the black with a ring terminal had 5v on it, assuming it's used for some isolation tests?

Re: VW Golf GTE battery
The first white appears to be 12v ignition, give it 5v and the other 2 voltage regulators start spitting out 5v. Just one wire left to identify now.
Re: VW Golf GTE battery
it would be great if these contactor control boards can be used on other projects!
I can arrange a few of these units if people want to play with them.

Re: VW Golf GTE battery
I've killed my contactor control board if you have any spare to play with.
Re: VW Golf GTE battery
I have...let's see if the UK is ready for normal shipments :p
Re: VW Golf GTE battery
I don't think so
PM me how much you want and paypal?

From 8:30, hammering of GTE cell module.
Any opinions are my own, unless stated otherwise. I take no responsibility if you follow my way of doing things and it doesn't work. Please double check with someone who knows what they are doing.

Re: VW Golf GTE battery
About what you said..
Basilicly some main points in video are.
- Firemen should not sink an EV, but to get access straight to the heated / on fire modules from top of battery.
- The battery modules should not catch fire very easily and are designed to hold during crash.
The module in video should be with NMC chemistry and 12 x 25Ah cells in the module by Sanyo(Panasonic)

Re: VW Golf GTE battery
I've got a second pack to play with. I've been able to get the contactors to close from the hybrid can thanks to some logs from DomT177
0x3A6 58 02 11 00 00 01 00 00 byte 1 (0 indexed) increaments to 0F and restarts, not yet sure if it cares about that. Byte 0 is always the same, so for 0x02 byte 0 will be 0x58.

This is the pinout of the external connector. To close the contactors 0x09C & 0x3A6 are needed on the hybrid can.0x3A6 58 02 11 00 00 01 00 00 byte 1 (0 indexed) increaments to 0F and restarts, not yet sure if it cares about that. Byte 0 is always the same, so for 0x02 byte 0 will be 0x58.

Hi I have a 2021- AUDI VW CUPRA SKODA 1.4 TSI High Voltage Battery 3Q0804841 3Q0915754 A. pack and like to use it with out hacking it about in side..
has any body manage to crack the can bus data yet for full control i.e. contactors and bms?

Re: VW Golf GTE battery
From the outside, if you replay this log https://github.com/jamiejones85/GolfGTE ... _KeyOn.asc on the hybrid can bus the contactors will close. I didn't look any further though.
