Increasing needs about how to evaluate maximum power of traction battery lead R&D of power test procedure for traction battery by supporting of MLTM(Ministry of Land, Transport and Maritime Affairs). To be adopted KMVSS, This power test procedure would be specific, possibly repeatable and anti-design-regulatable. As a first step for this R&D, other power test procedure for traction battery had been studied even though module level test procedure not a pack level. Traction battery"s dynamic power performance pattern had been also studied. On this paper, the power test procedure Ver. 1.0 developed by this R&D is evaluated by commercialized traction battery.

Successful commercialization of electric vehicle is depended on research and development level of traction battery being main component of Electric vehicle. Standard test procedure for Li-ion traction battery for performance, reliability and safety is under discussion in the standard of ISO-12405. This paper evaluated Energy-Capacity, Power and Energy efficiency at fast charging of Lead-acid and Li-ion battery pack in the view of ISO/DIS 12405-2. By the tests, This paper confirms the certain performance gap between commercialized Pb-acid and Li-ion traction battery pack. This performance gap would be caused by different material characteristic including chemical potential and internal resistance. The result of this paper could be applied to basic data when designing Battery Management System of traction battery pack. Also this paper evaluated the validity of test procedures of ISO/DIS 12405-2 by actual test.
