Basic use of battery pack management system

1. The basic functions of the battery management system (1) Monitor the working status of the single battery, such as detecting the voltage of the single battery, charging and discharging current, and the ambient temperature of the battery pack; (2) Protect the battery and prevent the battery life from shortening under extreme conditions And the battery is damaged. 2. Important functions of the battery management system (1) Over-voltage protection When the charging voltage of a single battery exceeds the allowable value, immediately stop charging and disconnect the charging device from the battery pack: (2) Over-discharge alarm when the single battery is discharged When the voltage is lower than the warning value, an alarm signal is issued. (3) Over-discharge protection When the discharge voltage of the single battery is lower than the protection value, the discharge is stopped immediately, and the electrical equipment is disconnected from the battery pack, accompanied by an alarm; (4) The over-current alarm is when the battery is input or output When the current exceeds the warning value, an alarm will be issued. (5) Short-circuit protection When the battery is short-circuited, it immediately stops discharging, disconnects the electrical equipment from the battery, and gives an alarm; (6) Over-temperature alarm When the battery temperature or ambient temperature exceeds the warning value, an alarm: (7) ) High temperature alarm When the battery temperature or ambient temperature exceeds the warning value, an alarm is issued. (8) Over-temperature protection When the ambient temperature or the internal temperature of the battery exceeds the protection value, immediately disconnect the charging or the connection between the electrical appliance and the battery pack, accompanied by an alarm. When the ambient temperature or the internal temperature of the battery returns to the allowable value, the battery management function can be restored manually or automatically without affecting the battery discharge function. 3. Estimate the battery SOC state of charge, that is, the remaining battery power. Keep the SOC within a reasonable range, prevent the battery from being damaged due to overcharge or overdischarge, and predict the remaining capacity of the battery at any time; 4. Balanced single battery Because the manufacturing process of lithium iron phosphate battery is complicated, the lithium ion is relatively active, so a single battery pack The battery voltage is not consistent. A single battery in the battery pack can be charged in a balanced manner, which can effectively extend the battery life and greatly improve the efficiency of the battery pack (can be increased or decreased according to user requirements). 5. Parallel communication supply and base station monitoring system communication interface, transmission and display of battery status, alarm, SOC and other information, to achieve remote monitoring and management intervention.
