Abstract

As a key issue in EVs (Electric Vehicles) development, Li-ion battery’s thermal safety is focused on in which the thermal abuse model is an important tool. This paper has established a 3-D electro-thermal model taking side reaction into account, in order to study on MGL100Ah lithium manganite battery’s safety issue. This paper firstly states the mechanism of heat generation, types of thermal model, and the mesh model, then analyzes the simulation on the model under the short circuit condition, one of thermal abuse condition. On one hand, the paper verifies the liability of the model, so as to apply the model on other thermal abuse condition in the future; on the other hand, the paper discusses in detail the internal temperature distribution, voltage and current changes under the short circuit condition. Analyzing this typical safety issue in details, this paper can help reduce cost, raise design efficiency and avoid thermal abuse in future development of battery.
