BMS wiring on Chevy Volt pack
I saw that Riso posted the Chevy Volt pin out here http://www.buggiesgonewild.com/extre...ms-pinout.html
I plan on using a Chargery BMS24T on it and I want to be sure its wired correctly. On my Leaf pack it was simple but the pin out for the Volt only shows 12 + and 3 low ref and 2 temp. Would I just start with the first low ref and then follow the + down the line? |

That's how I would do it. Start with my voltmeter at the first low reference (pin 2) then work my way down the chain of the battery voltage signal in order (pins 11 through pin 8 ).

re: BMS wiring on Chevy Volt pack
Thanks. I was hoping that was it. Now for another question.
If I'm running 2 packs in parallel would I just continue along that same line or would I have to split the wires to run both packs? |

Maybe this diagram with just the B- and cell number connections is easier to read:

re: BMS wiring on Chevy Volt pack
That's super easy...lol so the BMS 24T has 3 plugs - then 8 + . T next plug - go's to the junction for the next in series.
When I go to wire the second pack do I just keep going down the plugs? |

re: BMS wiring on Chevy Volt pack
Since your "serial" packs would be in parallel, You will either need 2 separate BMS units or use the same 12 taps and run the connectors in parallel.
I will defer to someone that has actually tried a single BMS for volt packs in parallel since the cells need to be balanced before the initial connection. |

So charge each module to 48v, verify each cell is very close to each other at 4v, then connect modules in parallel. After that connect cells in parallel and hook up the BMS. |
