Battery management system has a very extensive application field. This paper introduces an online system which is available for monitoring electric current, voltage and temperature of power battery group simultaneously. This system adopts the microcontroller and PC as the main controllers, collects the information like voltage, current and temperature of the battery with battery information collection...
One of the most essential and significant aspect of the battery management systems (BMS) is to estimate the state of charge (SOC) accurately, which can provide the judgment basis to system control strategy. In view of the lithium-ion power battery' s properties and its operation condition in electric vehicles, a new method named EKF-Ah that derives from the extended Kalman filtering (EKF) algorithm...
