Abstract
Battery peak power estimation has important theoretical significance and utility value for using battery properly and rising its lifetime; and it is one of important parts for battery management system. To estimate battery peak power under dynamic condition, an estimation algorithm with multi-parameters constrained based on dynamic battery model was developed. And the applicability of equivalent circuit models for Lithium-Ion batteries was analyzed. It is shown that with Thevenin model, the estimation algorithm with multi-parameters constrained could compute real-time peak power of the battery and could provide accurate charge/discharge power capability for electric vehicles so as to use battery correctly and protect battery.
