What is lithium battery BMS?
The battery management system, also known as BMS, is used to monitor and maintain the status of energy storage batteries. Its main responsibility is to intelligently manage and maintain each battery unit to prevent overcharging and over-discharging of the battery, thereby extending the service life of the battery.
BMS usually appears as a circuit board or a hardware box. It is one of the core subsystems of the battery energy storage system. It is responsible for monitoring the operating status of each battery in the battery energy storage unit to ensure the safe and reliable operation of the energy storage unit.
The functions of BMS are diverse and comprehensive. The three core aspects include:
The first is perception, which is state management. The basic function of BMS is to sense the status of the battery, which includes status parameters such as battery voltage, resistance, and temperature. We need to know what the status of the battery is, how much energy and capacity it has now, what its health status is, what its power output is now, and what its safety status is.
The second is management, which is balanced management. BMS is regarded as the nanny of the battery. Its responsibility is to manage the battery so that the battery can maximize its performance. This mainly includes balancing management and thermal management to ensure balanced and stable battery performance during use while preventing battery overheating.
Finally, there is protection, which is security management. If there is any abnormality in the battery, the BMS will protect it and issue an alarm. This is to ensure the safe use of the battery and prevent any possible dangerous situations. Through the above introduction, I believe you will have a deeper understanding of BMS.
