Now a big function from the board is to detect voltage and temperature. Secondly, does each cell mean each parallel cell or each one in a parallel connection. Since the voltages of parallel cells are ultimately the same through charging and discharging each other, detecting any one of them can represent all the cell voltages in a parallel.
The core functions of the BMS:
1) cell monitoring technology: 1) single cell voltage acquisition; 2) single cell temperature acquisition; 3) battery pack current detection;
2) SOC (state of charge) technology: simply how much power is left in the battery;
3) equalization technology.
