Problems solved by technology
Lithium batteries have many advantages, but they also have fatal disadvantages, that is, the battery stability is poor, and it is easy to spontaneously ignite and explode in extreme environments, so reasonable management of lithium batteries is required
In a humid environment, lithium batteries will be short-circuited due to material oxidation, circuit soldering, etc., resulting in danger. At present, the moisture-proof measures for lithium batteries are mostly sealed, but during the use of lithium batteries, the sealing will become more and more serious. worse, reduces the safety of lithium batteries in humid environments

Description
technical field [0001] The invention relates to the battery field, in particular to an electric vehicle battery protection device. Background technique [0002] At present, environmental pollution is becoming more and more serious, and automobiles are one of the main reasons for the global oil crisis and greenhouse gas emissions. Therefore, the development of clean energy vehicles is imminent. The emergence and development of electric vehicles represents the direction of new energy vehicles. Electric vehicles are powered by vehicle-mounted power supplies, driven by motors to drive wheels, and meet the requirements of road traffic and safety regulations. , and has less impact on the environment, and can replace the use of non-renewable energy gasoline. Therefore, the development of high-tech products for electric vehicles and the occupation of strategic commanding heights have great strategic significance and economic value for my country's energy security, energy conservati...
