Ensure System Level Reliability . The BMS management system of lithium batteries is particularly important . Multi-level BMS management must be used to identify faults and maintain in advance to control thermal runaway in the early stage to prevent fires . For example :
• The reliability of the cell is predicted by the internal short circuit algorithm .
• The BMS system has the current sharing control function .
Combine With Prevention and Fire Fighting . The reliability of Lithium battery depends on prevention . Once a fire occurs , the impact must be minimised to prevent the fire from spreading in the cabinet . In addition , the cabinet must be equipped with fire extinguishing methods . When a fire occurs , the cabinet can be started to quickly extinguish the fire . In-cabinet fire extinguishing modes can be module-level or cabinet-level .
