Self-consumption in different working modes:
· Normal Operating Mode: 13mA typical, 18mA maximum self-consumption.
· Sleep Mode: 200μA typical, 300μA maximum self-consumption.
· The system automatically back to normal operating mode from sleeping mode if current is <2A after no communication signal for 60mins.
· The system also will be back from sleep mode to normal operating mode if any charge or discharge activity is detected or if there’s communication signal again
Voltage protection
· As soon as one cell’s voltage exceeds the protection point, the charging process will be interrupted on the whole pack. The protection circuit returns to normal conditions as soon as all the cell’s voltage falls back to normal. Thedischarge will be allowed and the cell balancing will be activated.
· As soon as one cell’s voltage is under the protection point, the discharging process will be interrupted on the whole pack, BMS will be in energy-saving mode, The protection circuit returns to normal operation mode as soon as all the cell’s voltage charged back to normal. When BMS protected up on discharging, the charging processing is still allowed.
Current protection
· Software:
>>As soon as the discharging current exceeds the over current detection current during the detection delay time, the discharging process will be interrupted. The BMS returns to normal conditions after over current detection current released.
· Hardware:
>>As soon as the discharging current exceeds the over current detection current during the detection delay time, the discharging process will be interrupted. The BMS returns to normal conditions after over current detection current released.
ESD:
Battery is protected against electrical discharges:
- 15kV air
- 8kV contact
