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.
