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.
In the structure of new energy vehicles, the power battery pack structure is the most important power component, thus, it needs to be designed with a safer and more reasonable structure to meet the requirements of shock resistance and durability.
The results showed that the use of thermal insulation layers can effectively inhibit the thermal spread in the battery module. The average spreading time of each cell in the module with nanofiber insulation increased by 5.27 and 7.36 times, compared with that of the module without insulation.
An inner frame is used to support and fix the battery module and the battery pack box. An insulating plate is mainly laid under the battery pack box as an anti-leakage treatment. A series of temperature sensors are combined and distributed on the insulating plate according to the arrangement.
An insulating plate is mainly laid under the battery pack box as an anti-leakage treatment. A series of temperature sensors are combined and distributed on the insulating plate according to the arrangement. A cooling fan is installed on one side of the box to meet the requirements of circulating heat dissipation inside the battery pack box.
In the analysis of the vehicle side impact test, the rigid column invades the electric vehicle, which deforms the sill beam and the side of the battery pack box. Figure 10 shows the distribution of the stress nephogram of the battery pack box during the collision.
