Problems solved by technology
In order to improve the safety performance of the battery pack, it is necessary to analyze and test the cause of the thermal runaway of the battery pack. During the thermal runaway test, the battery pack will generate smoke and fire due to high temperature. On the one hand, it will pollute the external environment. On the other hand, it will lead to an unsafe test environment. Therefore, it is urgent to provide a battery pack thermal runaway test protection device that can meet the safety requirements.

The invention provides a battery pack thermal runaway automatic safe evacuation protection device and method. The device comprises a cooling pool, a lifting assembly, a protection cover, a smoke ventilator and a slide rail. The top of the cooling pool is open, and the cooling pool is filled with a cooling liquid. A battery pack is arranged on the lifting assembly, and the battery pack can sink into the cooling liquid of the cooling pool through the lifting assembly. The protective cover is connected to the sliding rail in a sliding mode, the sliding rail stretches across the opening of the cooling pool, a gap is reserved between the protective cover and the cooling pool, and when the protective cover slides to the position above the opening of the cooling pool, the lifting assembly covers the interior of the protective cover. The smoke ventilator is arranged on the protective cover and is used for exhausting smoke and heat generated by thermal runaway of the battery pack. The protection of the thermal runaway test of the battery pack is realized, the safety of test personnel and equipment is protected, the test safety and test efficiency are improved, and the test process is perfected.
Description
technical field [0001] The invention relates to the technical field of performance testing of automobile batteries, in particular to a protection device and method for automatic and safe evacuation of battery pack thermal runaway. Background technique [0002] The phenomenon of thermal runaway is an important factor reflecting the safety of battery packs. The occurrence of thermal runaway in general battery packs means that there is a safety problem in the battery pack, which needs to be dealt with in time to avoid danger and loss. In order to improve the safety performance of the battery pack, it is necessary to analyze and test the cause of the thermal runaway of the battery pack. During the thermal runaway test, the battery pack will generate smoke and fire due to high temperature. On the one hand, it will pollute the external environment. On the other hand, it will lead to an unsafe test environment. Therefore, it is urgent to provide a battery pack thermal runaway test ...
