Detailed explanation of the protection function of lithium iron phosphate battery

When the single battery charging voltage exceeds the allowable value, immediately stop charging and disconnect the charging device from the lithium-ion 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, the discharge will be stopped immediately, and the connection between the electrical equipment and the lithium-ion battery pack will be disconnected, accompanied by an alarm; ④Over-current alarm is when the lithium iron phosphate battery pack is input or When the output current exceeds the warning value, an alarm prompt will be issued; ③Short circuit protection When a short circuit occurs in the lithium iron phosphate battery pack, immediately stop discharging, disconnect the electrical equipment from the lithium ion battery pack, and accompanied by an alarm prompt; ⑥ Over-temperature alarm When the temperature of the lithium iron phosphate battery or the ambient temperature exceeds the warning value, an alarm will be issued: ⑥Over-temperature alarm When the battery temperature or the ambient temperature exceeds the warning value, an alarm will be issued. ⑦Over-temperature protection When detecting that the ambient temperature or the internal temperature of the lithium-ion 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 allowable value, the battery management function can be restored manually or automatically, but it does not affect the battery discharge function. 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. Prevent damage to the battery due to overcharge or overdischarge, and predict the remaining capacity of the battery at any time. Lithium iron phosphate battery 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 and the management system 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 centralized monitoring module, with four functions (remote measurement, remote signaling, remote control and remote adjustment) , Realize computer management, can communicate with remote central monitoring center.
