What is a Battery Management System?

A Battery Management System (BMS) is a device or system for efficiently and safely managing rechargeable batteries and battery packs. BMS applies to various types of batteries and battery packs, including lithium-ion batteries.

The main features of BMS include:
1. Battery status monitoring: BMS monitors parameters such as battery voltage, current, and temperature to understand battery status in real time. This allows you to detect dangerous conditions such as overcharging, overdischarging, and overheating and take preventive measures.
2. Charge/discharge control: BMS controls battery charging and discharging to achieve proper charging and discharging patterns. This can extend battery life and improve safety.
3. Cell balancing: A battery pack consisting of multiple battery cells must be balanced so that the voltage of each cell is equal. BMS provides cell balancing functionality, adjusting the charging and discharging of each cell to optimize the performance of the entire battery pack.
4. Safety features: BMS provides features to ensure battery safety. For example, safety features include the ability to shut down the system when abnormal temperatures or voltages are detected, and overcurrent protection.

Communication interface: BMS provides an interface to communicate with external control and monitoring systems. This allows you to remotely monitor and control battery status and performance. BMS is used in a variety of applications, including electric vehicles, hybrid vehicles, energy storage systems, and industrial battery systems. These systems are essential for maximizing the performance of batteries and using them safely and efficiently.
