Re: Chevy Volt Gen 2 charger 24281923

I've looked high and low but I cant find anywhere the pin layout for the GEN 2 battery charger control plug.
Can someone tell me where Pin 1 is? Or better yet a link to a pinout somewhere would be awesome.
I checked amber's blog and he describes the pins but I really could use the pin layout.
Thanks

Ok, i am away from PC now and cant do much. But observe in my blog how i used all black wires with numbers and single green/yellow wire. Well that is P2 GND (black wire in your photo) wire. P1 is not populated and then you can count wires from there. You only really need 4 wires P2, P4, P9 and P11.
I think you can also download molex connector datasheet to see pinout distribution.

I will draw a schematic when i am home...

Can the Gen2 Charger be controlled by CanBus?

No, gen2 charger needs PWM duty command to start and it reports with PWM duty on dc voltage and power.

Yes it is Volt gen2 charger. The gen1 was 3.3kW but it also had 250W 12V charger inside. So technicaly it was close to 3.6kW all in all.
I think 3.6kWh applies if you consider 9.3A at 380Vdc which i got from it on last try!

DANG! I tried to charge a 104S battery and Gen2 charger just wont work over 400Vdc.
Whereas when i tried with 96S battery it started to charge immediately.
That is a shame!

At the time i was ordering my set they were relatively good priced. Now they are unobtanium. I sold my charger but i was preparing to remove connectors and make alternative flanges with grommets for cables. Maybe model for 3d primter similar to outlander motor?
I think it would be easier to make new connection and seal it with sika or similar sealant.

I tried 378, 388V and 392V.
I also tried 410V and it would only start at 9A and shutdown after 1s.
