Waterproof heat-conducting lithium battery pack case

Abstract

The invention discloses a waterproof heat-conducting lithium battery pack case, which comprises an outer case and an outer case cover arranged at the upper end of the outer case, wherein an inner caseand a cold water tank are arranged one inner side of the outer case respectively, the bottom end of the inner case is communicated with the upper end of the cold water tank, the inner case and the cold water tank are welded through a stainless steel plate, one side of the cold water tank is communicated with a cold water storage container through a water duct on which a water pump is arranged, and an overflow pipe communicated with the cold water tank is arranged on one side of the cold water storage container. The waterproof heat-conducting lithium battery pack case is reasonable in design;a lithium battery module is arranged in the inner case and the inner case is arranged in the outer case, so that a better protection and waterproof effect on the lithium battery module is achieved; the lithium battery module is placed between a mounting plate and a pressing plate through tightening bolts, so that a clamping and fixing function is realized, the lithium battery module stored at thebottom of a vehicle is prevented from swinging in a running process, and normal work of the lithium battery module is further ensured.

Description

technical field [0001] The invention relates to the technical field of lithium battery packs, in particular to a waterproof and heat-conducting lithium battery pack casing. Background technique [0002] "Lithium battery" is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. Therefore, lithium batteries have not been used for a long time. With the development of science and technology, lithium batteries have become the mainstream now. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Li-ion batteries do not contain metallic lithium and are rechargeable. Lithium metal batteries, the fifth generation of rechargeable batteries, were born in 1996, and their safety, specific cap...

AI Technical Summary

Problems solved by technology

[0003] The lithium battery pack will be installed at the bottom of the electric vehicle. Because some items that are easy to leak are stored in the electric vehicle compartment, when the water seeps into the lithium battery storage box at the bottom of the vehicle compartment, the lithium battery will be damaged. In addition, the current The heat dissipation effect of some lithium battery storage boxes is not ideal, which will also affect the use of lithium batteries. Therefore, there is an urgent need for a waterproof and good heat dissipation box to store and install lithium batteries
