Battery Management Systems

The charging and discharging process in a battery has a significant influence on the life of the battery. The State of Charge (SOC) and State of Health (SOH) or Deliverable Energy depend on many parameters such as temperature, voltage and current, precise knowledge of these and other parameters are required for proper battery management. The objective of this project is to design and build a Battery Condition Monitoring System, which monitors the state of the battery; communicates with an Energy Management System and a battery charge voltage regulator, to prolong the life of the battery.

Start date: 16th of September 2002. This project has been completed.
