Thermal Simulation and Test of Lithium-Ion Battery for Electric Vehicle

摘要

With the aid of thermal model of battery and thermal simulation technology, the thermal behaviour of battery is researched in this paper. Computation of some physical property parameters of a 40Ah LiFePO4 battery is carried before the thermal simulation and test by several kinds of operating conditions. The simulation and test results are compared. The thermal model of lithium-ion battery is verified and the temperature gradient in the thickness direction is obtained. This provides a basis to the design and layout of battery thermal management system (BTMS).
