1. Functions and features of BMS:
Battery monitoring and equalization: BMS monitors the battery status in real time by monitoring the voltage, temperature, current and other parameters of the battery, and ensures that the voltage of each single unit remains consistent by equalizing the state of charge between the battery units to improve the overall performance and life of the battery pack.
Charge and Discharge Control: BMS monitors the charging and discharging process of the battery to ensure that the charging and discharging operations are carried out within a safe voltage and current range, in order to prevent over-charging, over-discharging and other situations that may lead to damage to the battery, and to ensure that the performance of the battery is optimized.
Temperature Management: The BMS monitors the temperature of the battery pack and takes measures to control the temperature within a safe range. Too high or too low a temperature will have a negative impact on battery performance and life, so the temperature management function of the BMS is crucial.
Fault diagnosis and safety protection: The BMS is able to detect battery pack faults and take timely measures to diagnose and protect them. When there are abnormal conditions such as over-voltage, under-voltage, over-current and over-temperature of the battery, the BMS will take corresponding measures, such as cutting off the current, alarming, etc., in order to ensure the safe operation of the battery and the whole system.
2. the key role of BMS in power battery:
Improve safety: BMS can effectively prevent potential safety risks, such as overcharging, over-discharging, over-temperature, etc., by real-time monitoring and controlling various parameters of the battery, so as to guarantee the safe operation of the battery and the whole system.
Extend battery life: The equalization function of the BMS can ensure that the state of charge between battery cells is balanced, avoiding too large a difference in capacity between cells, thus extending the life of the battery pack.
Improve energy utilization: The charge/discharge control function of BMS can ensure that the battery operates within the optimal working range, avoiding energy waste and improving the energy utilization of the battery.
Achieve intelligent management: Modern BMS is usually equipped with intelligent algorithms and data analysis functions, which can evaluate and predict the performance and health of the battery, and provide optimization suggestions to achieve intelligent management and optimization of the battery system.
As a key component of the power battery, the BMS plays a vital role in battery monitoring, protection and optimization. By improving safety, extending battery life, increasing energy utilization and enabling intelligent management, the BMS provides critical support for the reliability, performance and economy of power battery systems.
