A battery management system needs to perform the following tasks:
1. Monitor the battery voltage, current, and temperature.
2. Protect the battery from overcharging, over-discharging, and over-temperature.
3. Balance the cells in a multi-cell battery pack to ensure that all cells are within a safe voltage range.
4. Provide accurate state of charge (SOC) and state of health (SOH) information to the user.
5. Control the charging and discharging of the battery to optimize performance and extend the battery life.
6. Provide communication interfaces to allow the user to monitor and control the battery system.
7. Provide fault detection and diagnostic capabilities to identify potential problems and prevent damage to the battery.
8. Ensure compliance with industry standards and regulatory requirements.
