Abstract

The invention discloses a lithium battery passive waterproof system, which comprises a lithium battery and a casing. The lithium battery is provided with a conductive part, and the surface of the conductive part is coated with a layer of insulating waterproof glue by immersion; the lithium battery and the casing There is a circulating waterway between them. Also disclosed are a manufacturing method and a waterproofing method of the lithium battery passive waterproofing system and an electric vehicle. The passive waterproof system of the lithium battery fundamentally waterproofs the conductor to realize the insulation of the conductor; secondly, the water is effectively used after the battery enters the water, and the water entering the battery case forms a simple liquid cooling system. It can effectively control the temperature change of the battery and avoid the overheating of the battery during use. Moreover, the waterproof system is easy to manufacture, does not affect the effect and structure of the battery, and the method of waterproofing through the waterproof system and effectively using water for cooling has a good 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 ...
