The Internal Resistance Characteristics of Lithium-Ion Battery Based on HPPC Method

Abstract:

The real time power prediction of power battery pack used in electric vehicles is a difficulty of the battery management system. The internal resistance characteristic of the battery can be used to achieve the prediction of battery power based on the close relationship between the value of real time power and internal resistance. In this paper, the internal resistance characteristic of the power type lithium-ion battery are tested with HPPC(hybrid pulse power characterization) method, the relationship curves between the capacity or internal resistance of the battery and temperature are given, the temperature properties of the capacity and the ohmic resistance of the battery are obtained, and the basis of online resistance identification and peak power computation for the battery pack is provided.
