In this work, a hardware implementation of adistributed Battery Management System was carried out. Thishardware is formed by a current and voltage monitor, a SDcard, and a microcontroller, in which a remaining discharge timeprediction algorithm based on an extended Kalman filter wasprogrammed. The Kalman filter estimates the state of charge andanother dynamic variable that allow to use the Lambert functionto find the remaining discharge time from the end-of-dischargevoltage value. By using a commercial battery, the performanceof the algorithm was evaluated at different discharge rates.The experimental results show that the proposal is suitable tobe implemented on a embedded system or integrated into anapplication specific integrated circuit to be coupled in a batterypack.
