What are the functions of the battery management system for lithium-ion batteries

Li-ion battery BMS management system is not as dispensable as some battery production companies say, but must have. Lithium-ion battery management system has been studied at home and abroad, and has begun to be applied in many fields, which can meet In some markets, the application of lithium power lithium batteries puts forward higher requirements for battery management systems, and ensuring the safety of the power lithium battery pack is the primary task of the lithium power lithium battery management system. The BMS lithium ion battery management system can detect the voltage, current, temperature and other parameters of the power lithium ion battery in real time, realize the thermal management, balance management, high voltage and insulation detection of the power lithium battery, and can calculate the remaining capacity and charge of the power lithium battery. Discharge power and SOCu0026SOH status. The important task of the BMS lithium-ion battery management system is to ensure the design performance of the battery system, which can be broken down into the following three aspects: 1) safety, protect the battery cell or battery pack from damage, and prevent safety accidents; 2) durability , Make the battery work in a reliable and safe area, prolong the service life of the battery; 3) power, maintain the battery to work in a state that meets the requirements of the vehicle. The functions of the BMS lithium-ion battery management system usually include the following main functions: 1) Overcharge protection, lithium-ion batteries are not allowed to be overcharged. According to the characteristics of lithium-ion batteries, the battery is allowed to be charged in a specific voltage range. That is, disconnect the charging circuit to ensure the safety of lithium-ion battery charging. 2) Over-discharge protection. In addition to over-charging for lithium-ion batteries, over-discharging can also cause serious damage to lithium-ion batteries. Over-discharging is similar to over-charging. The trigger switch is set in a low voltage range below this voltage. The value is the sinking and discharging circuit. 3) Overcurrent protection, lithium-ion battery overcurrent protection includes charge current and discharge current protection, 4) Temperature protection, read the temperature value, sink or perform other protection actions when the specified value is reached. 5) Balance charging, which can have a longer service life for lithium-ion batteries, and charge the battery in a balanced manner. 6) Communication function, the communication function is not essential, it is mainly used to record and transmit the battery status data protocol.
