Seplos Active Balance Board can either be used separately or compatible with Seplos BMS 3.0. When reaching a threshold, BMS sends signals, and the balance board starts work. Thus to keep consistency of all cells in the battery pack. The board gets energy from the battery pack, and 3 circuits can be activated at the same time. Each circuit offers a 2A balance current.
Parameter
| Item | Threshold | Specifications |
Individual cells under voltage trip | 2800mV | The balance will stop 1 minute later if any of the cell voltage is under the threshold. |
Min. Voltage to start balance (the highest cell voltage) | 3000mV | Min. Voltage to start or stop balance is set to ensure balance functions at all statuses when charging, discharging, and standby. |
Min. Voltage to Stop balance (the highest cell voltage) | 2900mV | |
| Voltage difference for balance start | 50mV | Balance starts when the voltage difference is higher than 50 mV. |
| Voltage difference for balance stop | 30mV | Balance stops when the voltage difference is lower than 30 mV. |
| Balance duration | 60S | Balance starts and keeps for 60 seconds, then it will stop for 3s to check if the voltage gets the balance to the start/stop threshold. |
| Balance intermittence | 3S | |
| Balance timeout | 24H | After continuously balancing for 24H, the Balance will stop. |
| Temperature for balance continues | 70℃ | When the balance board temperature exceeds the threshold, the balance function will stop/recover accordingly. |
| Temperature for balance stop | 90℃ | |
| Standby duration | 10H | The balance board will turn off automatically if no balance for over 10 hours. |
| Balance current | 2A | Each circuit gets a 2A balance current. |
| Power consumption | 15mA | Power consumption less than 15mA at standby status. |
