A fault tolerant voltage measurement method for battery management systems is proposed for reliable and prompt cell fault and sensor fault detection. The key of the method is that it correlates one voltage sensor reading with multiple cell voltages and vice versa. When a cell fault occurs, fault readings will be revealed by multiple voltage sensor readings. Similarly, when a sensor fault occurs, multiple cell voltages will be influenced. Compared with the traditional one-to-one correspondence voltage measurement, the proposed method increases the credibility of sensor/cell fault decisions. Furthermore, it does not increase the hardware cost, and is easy to be adopted in real applications.
