The diagnostic performance of the model was verified through thermal fault imaging, and the following conclusions were ultimately drawn: Surface temperature can be used to detect thermal faults in lithium-ion batteries, and the proposed diagnostic model can effectively locate battery units in tightly arranged battery packs.
An experimental system for thermal spreading inhibition of lithium-ion battery modules was set up, in order to achieve the goal of zero spreading of thermal runaway between lithium-ion batteries in the module by using thermal insulation layer.
The thermal spreading interval between the thermal runaway battery and the neighboring batteries in the module is increased to an infinite length, and only the thermal runaway battery shows the phenomenon of spraying valve such as fire and smoke. It is expected to have a guidance for the design of thermal insulation in lithium-ion battery modules.
The positive and negative insulation resistance are quantitatively predicted. The condition monitoring and fault diagnosis of the lithium-ion battery system are crucial issues for electric vehicles. The shocks, blows, twists, and vibrations during the electric vehicle driving process may cause the insulation fault.
Integrating a physical thermal model and a deep neural network-based thermal model is a promising route for creating highly accurate thermal models which are necessary for the proposed lithium-ion battery thermal fault detection algorithm.
