Passive waterproof system of lithium battery, fabrication and waterproof methods of passive waterproof system and electromobile

Abstract

The invention discloses a passive waterproof system of a lithium battery. The passive waterproof system comprises the lithium battery and a shell, wherein a conductive part is arranged on the lithium battery, a layer of insulation waterproof glue is plated and coated on a surface of the conductive part by immersion, and a circulation water way is arranged between the lithium battery and the shell. The invention also discloses a fabrication method and waterproof method of the passive waterproof system of the lithium battery and an electromobile. By the passive waterproof system of the lithium battery, waterproof treatment is fundamentally performed, and the insulation of a conductor is achieved; water is effectively utilized after the water enters the battery, the water entering the battery shell forms a simple liquid cooling system, the temperature change of the battery can be effectively controlled, and overhigh temperature of the battery during the application process is prevented; and moreover, the waterproof system is convenient to fabricate, the effect and the structure of the battery are not affected, and the method for water prevention by the waterproof system and temperature reduction by effectively using water is good in effect.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a lithium battery passive waterproof system and its production, waterproof method and electric vehicle. Background technique [0002] With the current rapid development of the new energy industry and the country's strong support for the new energy industry, more and more electric bicycles are recognized by ordinary people. Due to the increase in users' demand for mileage and cycle performance, lithium battery electric bicycles are also received. Widespread concern. However, due to the high activity of lithium batteries, the problem of short circuit in water has always been a restrictive factor for the development of lithium battery electric bicycles. Consumers also attach great importance to the safety of lithium battery electric bicycles in water short circuit. At present, lithium batteries for electric bicycles on the market, Mainly rely on the sealing design of the ...
