What happens if the heat dissipation effect of energy storage system is not good?
If the heat dissipation effect of the energy storage system is not good, it may lead to thermal runaway, which will cause short circuits, bulging, and open flame problems of the battery, which may eventually lead to safety accidents such as fire or explosion.
What are the hazards of battery overcharge and overdischarge?
The hazards of battery overcharge and overdischarge Overcharge: Overcharge means that when the lithium-ion battery is overcharged, the charging voltage exceeds the set voltage, such as the rated voltage of the battery is 3.7V, and the fully charged voltage is 4.2±0.05V.
What happens if the battery voltage reaches the Protection Board?
3) When the battery voltage reaches the voltage set by the protection board, the protection board will cut off the power to protect the battery, but the lithium-ion battery will fall back, and the voltage will rise, which will be a little higher than the voltage set by the protection board. At this time, it can no longer be used.
What is a battery energy storage system?
Battery energy storage systems (BESS) stabilize the electrical grid, ensuring a steady flow of power to homes and businesses regardless of fluctuations from varied energy sources or other disruptions. However, fires at some BESS installations have caused concern in communities considering BESS as a method to support their grids.
How to protect a lithium-ion battery from overcharging?
1) Using a lithium-ion battery with a BMS management system, the protection board can protect the battery from overcharging or over-discharging, and can also communicate with the inverter to automatically set the correct charging and discharging parameter values, which can better protect the battery.
What happened at Dahongmen energy storage power station?
On April 16, , a fire and explosion at the Dahongmen Energy Storage Power Station in Beijing killed one electrician on duty, two firefighters died, and one firefighter was injured.
