Consider the safety of lithium battery UPS power supply

1. High-quality cell processing and quality control. At present, the world's outstanding lithium battery manufacturers have adopted advanced automated processing lines. Only through high-quality processing technology control can the high quality and high consistency of the cells be guaranteed. Due to the strict quality control of lithium battery UPS and its own cycle life has been greatly improved compared to lead-acid batteries, in the field of data centers, many major brands of lithium batteries can be guaranteed for 10 years. 2. Perfect BMS design The BMS lithium battery management system is the core technology for the safety of the entire lithium battery system. When the UPS battery has any faults such as over-voltage charging, over-current discharge, battery short-circuit, etc., the fault current can be quickly cut off through the BMS to guard against the risk of thermal runaway of the battery. 3. Lithium battery chemical materials. Regarding data center lithium battery UPS, due to its short-time high-current discharge, large discharge power, long-term backup and floating charge, etc., the more suitable ones are lithium iron phosphate, lithium manganate, and NCM. Ternary lithium technology. It is believed that the safety of the lithium battery UPS power system should comprehensively consider the negative electrode material, electrolyte, diaphragm material, cell shell packaging, battery module grouping, BMS, fuse protection, DC circuit breaker, processing and manufacturing process level, quality control, etc. Many factors. 4. Compatibility detection between lithium battery and UPS is different from that of lead-acid battery. Lithium battery comes with BMS. It is a kind of intelligent battery with self-management ability and communicates with UPS host. When the lithium battery overflows, it will automatically disconnect from the UPS charger. The traditional UPS software design may think this is a battery failure and issue an alarm. Therefore, before using the lithium battery UPS, it is necessary to perform strict matching detection with it, and update the firmware of the UPS for this lithium battery.
