- All mentioned variables are located in folder

Balancing configuration
Balancing is allowed in states IDLE and greater.
| Parameter | Description |
|---|---|
cellBalVoltage | If voltage of cell is above this value, balancing of that cell is allowed. |
balStartDelta | If the difference between the highest and lowest cell voltage is above this value, balancing is started. |
balEndDelta | If the difference between the highest and lowest cell voltage is below this value, balancing is stopped. |
maxSimBal | Maximum number of cells balanced at one moment. If there is overtemperature of balancer, the BMS will automatically reduce number os balanced cells. |
Balancing states
| State | Description |
|---|---|
balCmd | 1: Balancing is allowed. 2: Balancing is forced (ignoring) cellBalVoltage parameter and BMS state |
balState | 1: At least one cell is balancing 2: Balancer overtemperature 4: Cell overvoltage 8: Cell undervoltage 16: Cell check error 32: Balancer failure 64: Critical undervoltage |
badCells | Signalize bitwise cell with error. - If cell is expected and voltage is below 100mV - If the cell is not expected and voltage is above 100mV |
*All the states are bitwise
