摘  要:
Battery, as an important part in a hybrid electric vehicle (HEV), its characteristic should be well understood in order to do HEV platform test correctly. However, battery parameters are non linear and very complicated, and the accurate theoretical models of these parameters are very difficult to be set up. A simple and practical method to evaluate the parameter of battery state of charge (SOC) was presented in the paper. The lead acid battery parameter SOC and its effective capacity characteristic were tested on the platform. The data of voltage, current and temperature were collected and monitored. A satisfied parametric evaluation for SOC was obtained from the actual capacity.
