摘要：
Accurate information regarding the maximum available pulse current can help to determine the power capability of the battery and allow the battery to be operated within the safe operating voltage range. However, although estimation methods of the maximum available pulse current have been developed, they have the drawback of variation in the resistance inside the batteries. In this paper, the state of charge (SOC) and resistance of the battery are estimated from the dual extended Kalman filter (Dual EKF). Furthermore, the lumped resistance, which represents the impedance inside the battery during the predefined time, is calculated using an easy numerical calculation based on the estimated values.
