Abstract

The invention provides a sealing verification device of power battery, and relates to the technical field of power battery protection and verification. The verification device comprises a water tank,a bearing structure and a fixation part; the bearing structure bears a battery pack to be verified; the fixation part can move close to or far from the water tank via a support telescopic structure; when fixed part moves close to the water tank, the bearing structure can be moved into the water tank; and a connection structure is provided with an actuation part, and the bearing structure and battery pack can be driven to move according to a preset manner. The fixed part can move close to or far from the water tank via the support telescopic structure, the bearing structure can be moved into the water tank when the fixed part moves close to the water tank, the actuation part can drive the bearing structure and battery pack to move according to the preset manner, so that sealing of the battery pack can be verified in both dynamic and static modes.

Description

technical field [0001] The invention relates to the technical field of power battery protection verification, in particular to a power battery sealing verification device. Background technique [0002] The power battery is the core component of electric vehicles, and the sealing of the battery pack is very important. At present, for the battery pack, there is only the seal protection verification under the condition of static submersion, but it lacks the seal verification under different working conditions of the simulated vehicle. Therefore, the traditional method cannot fully verify the seal protection of the battery pack. [0003] Therefore, there is an urgent need for a power battery sealing verification device that can verify the sealing protection of the battery pack when submerged in water under static and dynamic conditions. Contents of the invention [0004] An embodiment of the present invention provides a device for verifying the sealability of a power battery,...
