Analysis of important functions of lithium iron phosphate battery pack management system

When the single battery charging voltage exceeds the allowable value, immediately stop charging and disconnect the charging device from the lithium battery pack: ②Over-discharge alarm When the single battery discharge voltage is lower than the warning value, an alarm will be issued; ③Over-discharge protection When the discharge voltage of the single battery is lower than the protection value, stop the discharge immediately, disconnect the electrical equipment from the lithium battery pack, and an alarm prompt; ④Over-current alarm When the lithium iron phosphate battery pack input or output current When the warning value exceeds the warning value, an alarm will be issued; ③Short circuit protection When the lithium iron phosphate battery pack is short-circuited, the discharge will be stopped immediately, and the connection between the electrical equipment and the lithium battery pack will be disconnected, accompanied by an alarm prompt; When the iron-lithium battery temperature or ambient temperature exceeds the warning value, an alarm will be issued: ⑥Over-temperature alarm When the battery temperature or ambient temperature exceeds the warning value, an alarm will be issued. ⑦Over-temperature protection When it is tested that the ambient temperature or the internal temperature of the lithium battery pack exceeds the protection value, immediately disconnect the charging or electrical equipment from the battery pack, accompanied by an alarm. When the ambient temperature or the internal temperature of the lithium iron phosphate battery pack returns to the permitted value, the battery management function can be restored manually or automatically, but the battery discharge function will not be affected. ⑧ Estimate the battery pack SOCSOC (StateOfCharge, the state of charge of the battery), that is, the remaining battery power. Keep the SOC within a reasonable range. Be wary of damage to the battery due to overcharge or overdischarge, and predict the remaining capacity of the battery at any time. Lithium iron phosphate battery pack management system BMS is the core component of battery protection and management, not only to ensure the safe and reliable use of the battery, but also to give full play to the performance of the battery and prolong the service life, as the backup power for communication, the management system is in It serves as a bridge between the high-voltage DC power supply and the battery. The positive electrode of lithium iron phosphate battery is made of lithium iron phosphate (LiFePO4) material, which has good safety performance and long cycle life; fully intelligent design, equipped with aggregate monitoring module, has four functions (remote measurement, remote signaling, remote control and remote adjustment). Computer management can be achieved by communicating with the remote central monitoring center. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
