Important functions of the iron phosphate battery pack management system

A lithium iron phosphate lithium-ion battery management system will allow a group of "dumb" like cells into an intelligent lithium-ion battery pack, management can be split into two sciences, battery monitoring and battery control; monitoring part includes voltage and temperature measurement and battery balancing. These are the basic attributes of lithium-ion iron phosphate battery management system.

Important features of lithium-ion LiFePO4 bms

①Over-voltage protection

When the single battery charging voltage exceeds the allowed value, immediately stop charging and disconnect the charging equipment from the lithium-ion battery pack:

②Over-discharge alarm

To issue an alarm prompt when the discharge voltage of a single battery is below the warning value.

③Over-discharge protection

When the discharge voltage of the single battery is lower than the protection value, immediately stop discharging and disconnect the power-using equipment from the lithium-ion battery pack, accompanied by an alarm prompt.

④Over-current alarm

When the input or output current of lithium-ion iron phosphate battery pack exceeds the warning value, an alarm will be issued.

③ short-circuit protection

When the lithium-ion iron phosphate battery pack short-circuit, immediately stop the discharge, disconnect the power equipment and lithium-ion battery pack, accompanied by alarm prompts; ③ short-circuit protection.

⑥ Over-temperature alarm

When the lithium-ion iron phosphate 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 prompt is issued.

(7) Over-temperature protection

When the ambient temperature or lithium-ion battery pack internal temperature is detected to exceed the protection value, immediately disconnect the charging or power-using equipment from the battery pack, accompanied by an alarm prompt. When the ambient temperature or lithium-ion phosphate battery pack internal temperature returns to the allowable value, the function of battery management can be restored manually or automatically, but does not affect the battery discharge function.

⑧ Estimation of battery pack SOC

SOC (StateOfCharge, the state of charge of the battery), that is, the remaining battery power. Maintain the SOC within a reasonable range. Prevent damage to the battery due to overcharge or overdischarge, and forecast the remaining capacity of the battery at any time.

Lithium iron LiFePO4 BMS is the core component of battery protection and management, not only to ensure the safe and reliable use of the battery. And also to give full play to the performance of the battery and extend the service life, as the backup power for communications, management system between the high-voltage DC power supply and the battery to play a bridge purpose.

Lithium iron phosphate battery cathode using lithium iron phosphate (LiFePO4) material production, good safety performance, long cycle life; full intelligent design, configured with a centralized monitoring module, with four to (telemetry, telematics, remote control and remote control) function, to achieve computer management, can be communicated with the remote central monitoring center.

Lithium-iron phosphate battery pack unit in one, with small size, light weight, safety and environmental protection, high reliability, strong function, flexible configuration, lithium-iron phosphate battery management system is important to the lithium-ion battery working parameters collected as a reference, real-time control to protect the normal work of lithium-ion batteries.
