The battery test methods are the key issues to investigate the energy-storage characteristics and dynamic characteristics of electric vehicle (EV) batteries. In this paper, the research advances of existing battery test methods as well as driving cycles are reviewed. An electric vehicle model that consists of EV dynamics model, battery model and electric motor model is built. The dynamic characteristics of the battery in frequency domain are analyzed. Based on the EV model and the frequency domain characteristics of the battery, a driving cycle test procedure of EV battery is proposed. The battery test procedure is able to reflect the real-world characteristics of EV batteries, and can be used as a universal EV battery test method.
