Battery management refers to the processes and technologies used to monitor and control the performance of rechargeable batteries. This includes ensuring optimal charging and discharging, maintaining battery health, and extending lifespan. Effective battery management systems (BMS) help prevent issues like overcharging, overheating, and deep discharging, which can damage batteries and reduce their efficiency. A BMS typically includes sensors and software that track various parameters, such as voltage, current, and temperature. By analyzing this data, the system can make real-time adjustments to improve performance and safety. Proper battery management is crucial in applications like electric vehicles, renewable energy storage, and portable electronics.
