Vibration reduction and heat dissipation system for vehicle-mounted battery pack

Abstract

The invention provides a vibration reduction and heat dissipation system for a vehicle-mounted battery pack, comprising a battery pack, a storage device, a vibration reduction device, a fixing deviceand a heat dissipation device. The battery pack is arranged in the storage device. The vibration reduction device, the fixing device and the heat dissipation device are arranged on the storage device.The storage device comprises a plurality of storage check blocks, and the storage check blocks are connected end to end to form a storage groove. The vibration reduction device is arranged on the periphery of the storage groove. The heat dissipation device is arranged on the inner wall of the storage groove and fixedly connected with the inner wall of the storage groove. Because vibration reduction components are arranged in the vertical and horizontal directions and are separately and independently arranged, it is guaranteed that vibration borne by the battery box in all the directions can be attenuated. Meanwhile, through independent assembly replacement, the replacement cost of the whole set of vibration reduction assembly is reduced and the working efficiency is improved.

Description

Technical field [0001] The present invention relates to the technical field of automobile power batteries, in particular to a vibration reduction and heat dissipation system for a vehicle battery pack. Background technique [0002] Most of the current new energy electric vehicles use storage batteries as their power source. Multiple batteries are connected to each other to package a battery pack. However, there are some shortcomings in the damping and heat dissipation of electric vehicle battery packs: The battery pack produces varying degrees of vibration, which is easy to damage the battery; the battery generates a lot of heat during the working process, and the heat cannot be dissipated in time, which will seriously affect the performance of the battery pack and shorten the battery life. [0003] For example, US09045033B2 prior art discloses a damping control device. When the lateral reaction force of each wheel changes, the balance of the lateral reaction force of the vehicle a...

Problems solved by technology

[0002] Most of the current new energy electric vehicles use batteries as the power source, and pack a battery pack by connecting multiple batteries to each other. However, there are some shortcomings in the vibration reduction and heat dissipation of electric vehicle battery packs today: the car will Make the battery pack vibrate to different degrees, which is easy to damage the battery; the battery will generate a lot of heat during operation, and the heat cannot be dissipated in time, which will seriously affect the performance of the battery pack and shorten the service life of the battery

[0004] In order to solve the common problems in the field that there is sloshing in the battery cavity, a single vibration damping device, the battery pack is not waterproof and the heat dissipation effect is not good, etc., the present invention is made
