Multiplexed Voltage Measurement for Serial Connected Power Li-Ion Battery String

Abstract:

This paper proposes a new method of multiplexed voltage measurement for serial connected power lithium battery string. The method has some advantages such as simple circuit, the simultaneous measurement and high accuracy. The principle of the voltage measurement circuit is analyzed in this paper, and proposes the solution to the factors affecting the measurement precision of the circuit. Experiments show that this circuit leakage current and temperature drift is small, and also have high precision.
