At present, the Lithium-ion battery are the most used batteries in a large number of applications because of its high performances. It is important for Lithium-ion battery to make objective and accurate judgment to its performances before the practical application. A multi-channel high precision Lithium-ion battery test system, which could realize complex measure control, was designed in this paper. The system consists of upper computer (PC) and lower computer (control circuit unit). The communication between upper computer and lower computer is through RS-485 bus. The control circuit unit, which is mainly composed of micro-processor, control circuit, data acquisition circuit and protection circuit, can realize the function of testing Lithium-ion battery performances such as charging, discharging, internal resistance. Furthermore, based on actual use conditions it has shown that the system can accurately measure various Lithium-ion performance parameters and the current measurement accuracy can satisfy the test requirements.

Joint Experiment

According to the demand of vehicle lithium-ion battery pack, the splice equivalent circuit model is constructed. First, a joint experiment of intermittent discharge and hybrid power pulse characterization, basis of the requirements of parameter identification for the model, is designed to identify the parameters. Study shows that it can identify the parameters. Second, the splice equivalent circuit model of vehicle lithium-ion battery pack is simulated by MATLAB/Simulink, which shows the model is feasible to describe the vehicle lithium-ion battery pack. The simulation error of ohmic internal resistance R0 should be less than 0.05 mΩ. Study suggests that the vehicle lithium-ion battery pack has a stable discharge period within the state-of-charge range of [20%, 80%]. However, when stage of charge is below 20%, vehicle lithium-ion battery pack is no longer stable and the parameters of the splice equivalent circuit model change dramatically.
