Application
-
Small apartment / rental home energy storage
Adaptation advantages: The stacked design only occupies 0.3㎡ of floor space (about the size of a bedside table), no installation required, can be directly placed on the balcony; 10.24kWh capacity supports the continuous operation of refrigerator + lighting + router for 3-5 days, with temperature resistance of -30℃~50℃, suitable for most areas in the region, covering "small apartment stacked ESS" and "household energy storage".
-
Backup power supply for small commercial places
Adaptation advantages: 20.48kWh capacity can support the operation of convenience store freezers + cash registers for 6-8 hours; modular stacking supports expansion to 30.72kWh, replaceable battery packs avoid waiting for charging during power outages, covering "small commercial stacked energy storage" and "convenience store backup ESS".
-
Outdoor temporary power supply (camping / small-scale construction)
Adaptation advantages: A single module weighs about 25kg and can be manually carried, IP20 dustproof suitable for dry outdoor scenes; 5kW rated output can power electric drills, lighting, portable ovens, replacing fuel generators to achieve noise-free and clean power supply, covering "outdoor temporary energy storage scenarios".
The role of the Battery Management System (BMS).
-
Real-time monitoring:The BMS monitors parameters such as voltage, current, and temperature of each battery cell in real time through sensors to ensure the health status of each cell.
-
Equalization management:The equalization circuit (Balancing Circuit) in the BMS is used to adjust the voltage differences between each battery cell. When a cell voltage is detected to be lower than the set value, the equalization circuit will perform voltage compensation in a passive or active way to make the voltages of all cells tend to be consistent.
Equalization strategies.
-
Passive balancing:Excess charge is dissipated through resistors connected in parallel to the battery cells, thereby making the voltges of each cell tend to be consistent.
The disadvantage is that it can only work during the battery charging process and has a large energy loss. -
Active balancing:Using a bidirectional converter or a dedicated equalization chip to transfer charge between battery cells to achieve energy transfer, thereby making the voltages of each cell consistent.
The advantage is that it can be adjusted bidirectionally. It can equalize during charging and discharging, and has low energy loss.
