Abstract

Abstract:

The convective heat transfer coefficient (CHTC) is an important parameter in the process of the lithium-ion battery (LIB) thermodynamic simulation and is usually set to a fixed value during this process. Although satisfactory simulation results can be obtained, the simulation process cannot be consistent with the actual situation, and the temperature rise characteristics during the battery discharge cannot be accurately predicted. The variable CHTC (VCHTC) can change with the battery discharge and improve the simulation process accuracy. This study investigates the temperature rise characteristics of a single LIB (SLIB) under variable ambient temperatures and discharge rates. The battery heat generation optimization model is established using the VCHTC. The comparison results between the simulations and the experiments on the SLIB under normal working conditions show that the simulated process temperature of the VCHTC and the constant CHTC has mean absolute percentage errors of 1.1% and 6.9%, respectively, at various operating conditions.

Key words: convective heat transfer coefficient, lithium-ion battery, thermodynamic simulation, temperature rise characteristics, mean absolute percentage error
