Sleep switch occupancy reservation: Reserve the occupancy slot for the Sleep switch to enable power saving when the device enters sleep mode. Low standby current: The device draws less than 0.1 mA in the idle state, minimizing parasitic loss during standby. Battery aging and voltage balance: With increasing charge-discharge cycles, the rate of capacity loss can become more irregular, which can lead to a serious imbalance in battery voltages. The device helps mitigate this risk by actively balancing the pack. Balancing current and behavior: Balancing current range is 0 A to 5.5 A. When the voltage difference between cells is 0.1 V, the balancing current is 1.0 A. The voltage difference is proportional to the balancing current, so the more imbalanced the cells are, the higher the balancing current. The more balanced the pack, the lower the current required. Balancing voltage accuracy: The balancing voltage is accurate to within 5 mV. Applications and use scenarios: - Multi-cell battery packs in solar power storage systems: Use this device to maintain cell voltage balance over long operating life and varying sunlight conditions. - Off-grid backup power systems: Keep cell voltages aligned during extended standby and cycling, reducing the risk of early cell failure. - Battery test benches and cycling experiments: Employ active balancing to observe and control voltage differences during long-term charge-discharge testing. Performance highlights: - Active balancing with selectable current up to 5.5 A - Precise voltage balancing with 5 mV accuracy - Low idle power to minimize waste during standby - Addresses aging-induced voltage imbalance and prolongs overall pack reliability Notes: - Suitable for battery packs requiring precise cell balancing to maintain pack integrity and performance. - The balancing current responds to cell voltage differences, increasing as imbalance rises and decreasing as balance improves.
