Hello guys,
the project is to obtain the optimal parameters for our battery profile with the CEDV method.
The requirements are:
- 7 amps (lowrate) @ 2.5°C, roomtemperature and 45°C
- 15 amps(highrate) @ 2.5°C, roomtemperature and 45°C
Battery Specs:
- 4 cells in series
-14 cells parallel
- 58 volts end of charge
- 39 volts end of discharge
Now the Problem: If i test the batterypack with 15 amps the BMS switches the battery off, because the cells exceed 60 °C cell temperature, so we do not have a chance to discharge the battery from 100% to 0% SOC. Is it a requirement to make a constant discharge with 15 amps at every temperature or can we vary the current for different temperatures.
Thank you!
