I got some good data from post in https://www.diyelectriccar.com/threads/ ... ost-954522
Mechanically cells are similarily shaped and i think i can make some sheet metal clamping to fasten the cells in previous mountings.I ran water through my batteries (2015 Volt, 12s module) at different temperatures and measured the resistance of the two sensors (one in each module). Resistance values are in thousands of ohms:
Temp °F__R1 kΩ__R2 kΩ
35_______27.1___30.9_
50_______18.5___18.9_
70_______12.5___12.4_
100______6.4____6____
115______4.6____4.2__
130______3.3____2.9__
In first place i need to connect the cells to BICMs and test BMS data output using SimpBMS. When everything is running OK i will move forward and gut our Ampera car and try to use it with BMS in the car.
Original Volt Gen1 BMS connectors are not good for Gen2 because they have plastic extrusions located in the wrong place for them to fit in the socket. However i found out Molex Minifit 5557-18R connectors have correct pin spacing and socket is correctly placed. P/N 39012180.
However connector does not lock in the socket even though it is quite a tight and deep fit. It is not possible to turn connectors incorrectly.
I am expecting Molex Minifit 5557 connectors with crimp pins soon.
