The development of new energy vehicles mainly based on pure electric vehicles is an important means for China to achieve overtaking in the automobile industry. If the pure electric vehicle industry develops smoothly, it will become a new economic growth point that supports the steady and rapid growth of China ’s economy in the future, and will also drive cars. The rapid development of related industries and technological progress. However, as far as the current level of development of pure electric vehicles is concerned, there are serious hidden safety problems in the battery segment alone. Under the general trend of fast development in various regions, such hidden safety problems are difficult to be concerned. However, the recent electric vehicle explosion and fire incidents fully illustrate that once a hidden battery safety hazard erupts, its harmfulness is difficult to estimate, and it must be prepared for, through strong means, to prevent pure electric vehicle accidents that may be caused by the hidden battery safety hazard. 5 levels ". The first level is the battery material level. Lithium batteries are regarded as important power batteries for pure electric vehicles due to their advantages over traditional power batteries such as lead-acid batteries and nickel-cadmium batteries. However, the lithium battery itself is not perfect, and there are certain safety risks due to the chemical activity of the lithium element. The current technology is difficult to completely eradicate. Therefore, while optimizing the performance of traditional lithium-ion batteries, we must explore and develop new types of lithium batteries, next-generation power batteries, and fuel cells to support battery companies and pure electric vehicle manufacturers to form a technical alliance to jointly break through the attributes of battery raw materials. Potential safety hazards brought by the development of electric vehicles. The second level is battery quality level. Quality is a key element of products widely accepted by consumers. Especially when the product is in the market cultivation period, the overall quality level directly determines whether the product can quickly open the market. During this time, no matter which kind of product causes negative social impact, the overall image of such products will be in the minds of consumers Great discount. In particular, there are currently a large number of companies producing batteries for pure electric vehicles, with uneven technology and process levels, and the key technologies in battery separators, electrolytes, manufacturing processes, etc. have not been able to make breakthrough progress, and related companies must guarantee The quality of the battery when it leaves the factory, especially the protection measures for explosion-proof and anti-spontaneous combustion of the battery, must be perfected. At present, the conventional protection design must be available, and battery quality problems should be strictly investigated. If it is a battery manufacturer that improves the supporting battery for a certain company's pure electric vehicle, and this battery has serious safety risks, both parties should be held accountable. The management department of the industrial industry should issue a corresponding market access system to regulate the production of battery companies through access standards such as technology, process, and safety. At the same time, the quality inspection department must conduct strict inspections on the batteries shipped from the factory to prevent inferior batteries from entering the market. The third level is battery use level. The increase in explosions of lithium battery products in recent years is largely due to consumers' failure to pay attention to the details of the use of lithium battery products and the inability to use lithium battery products correctly. It is recommended that relevant government departments and enterprises guide the consumers ’use of batteries in this regard, and promulgate relevant rules and regulations to focus on how to guide consumers how to charge, discharge, and store batteries correctly, and how to discover the occurrences of batteries during use. It may lead to hidden dangers of safety accidents, and at the same time, strict regulations should be made on the prohibition of use and recycling of the battery charging and discharging time, environment and end of life battery. The fourth level is the battery test level. The test is a problem that the local government departments and enterprises have been neglecting under the vigorous development trend of pure electric vehicles in recent years. Due to the lack of sufficient test data on various conditions, driving and collisions of pure electric vehicles in the environment, many companies and local government departments believe that local pure electric vehicles are no problem, so they are introduced to the market prematurely. At the same time, it is difficult for the departments that set standards to determine what standards should be adopted for the development of pure electric vehicles, and some hidden safety risks in the battery are also covered. However, this does not mean that this hidden danger has been eliminated. On the contrary, it is very likely that it will be concentrated in a certain period of time in the future. Therefore, in the absence of sufficient test data, the promotion of pure electric vehicles should also be delayed. It is recommended that the relevant government departments coordinate and organize relevant scientific research units, battery production enterprises, and pure electric vehicle production enterprises to do related testing work for pure electric vehicles and batteries. The fifth level is the battery standard level. As the industry of pure electric vehicles and supporting power batteries is still in the stage of cultivation and development, the strong support of national policies will attract funds to flow into this field, and a large number of enterprises will flock in, which will inevitably cause the overall technical level and performance standards of the battery product market to be uneven. The country's consideration in charging pure electric vehicles requires that the battery must meet certain standards. In addition, the technology, industry, basic performance, safety and operation of the battery production also need to have standards to regulate. Therefore, it is recommended that the relevant departments should formulate battery standards for pure electric vehicles as soon as possible based on the data from various tests of battery use and the performance requirements of charging equipment and pure electric vehicles on batteries.
