In the process of power battery testing safety technical analysis

Source: 2020 - 04 - 11: when click traffic safety protection technology analysis to the process of power battery testing [ Abstract] In recent years, along with our country social environment problem increasingly prominent, the new energy vehicles more and more get the favour of people, power battery in the use of new energy vehicles is more and more frequent, its good quality and performance is an important guarantee of the safe operation of the car. Therefore, when to test the power battery, do a good job security protection is very important. In this paper to protect the safety of the power battery technology is analyzed. 【 Keywords 】 Power battery; Detection; Safety protection in recent years, China's air pollution is serious, the fog haze weather frequent, urban pollution index exceeds bid is very serious, city dwellers suffered great threat to life and health. According to the current human consumption of coal, oil and other fuels, the fuels will be consumed in a few decades, before that, the development of alternative energy to drive a car is a focus of research. 1. The development trend of power battery is ni-mh power battery technology is one of the most mature, the most successful commercial, the most widely used type of power battery, 1] But the effectiveness of the battery technology has reached the limit, with the rapid development of science and technology, lithium-ion batteries for its superior performance in the field of vehicles, won the majority of manufacturers, believe in the near future, will gradually replace the nickel metal hydride batteries, lithium ion battery has become the mainstream in the current era and the future research direction in the field of automobile. And no matter what kind of power battery, in order to ensure the good performance of application of the detection are effective security protection technology and measures should be taken. 2. Check the power battery safety protection technology in recent years, people's environmental protection consciousness gradually strengthened. At this point, the power battery because of its strong environmental performance and favored by automobile manufacturers. Therefore, increasing the safety of the power battery especially ni-mh power battery testing is very important. That is to say, should adopt certain security protection technology, ensure that power battery testing in a safe environment. 2. 1 to strengthen personnel training, improve the comprehensive quality of inspectors of power battery testing needs corresponding personnel with high psychological quality, not only should have professional technical knowledge and rich experience in the field, also have a high sense of responsibility and serious working attitude. Therefore, the relevant departments to strengthen all aspects of inspection personnel training, and actively organize to carry out various training activities, at the same time not to detect personnel on a regular basis to learn professional knowledge. For some people, on the other hand, has the high enthusiasm and strong ability of absorption of young workers, relevant departments can provide some opportunity to go abroad, learn foreign advanced science and technology and field experience, at the same time with power battery in our country, the combination of detection technology and method on the basis of innovation, to create a show the characteristic of power battery safety testing technology and method, ensure the safety of the power battery test environment. In addition, testing and maintenance of equipment maintenance personnel should be timely, and make inspection records. Report to the superior departments. If a significant failure in experimental equipment, after troubleshooting, must be identified or qualified rear can use. At the same time, in order to increase the safety factor of the work, the relevant departments should increase investment in equipment, the introduction of foreign advanced power battery testing equipment in a timely manner. 2. 2 area experiment was carried out, to install the necessary protective facilities in test power battery, if do not pay attention to, easy to cause the explosion and fire. To avoid such dangerous situation, the test field should be divided into the experimental area of sample and experiment control two parts. One sample experimental area for the storage area of the power battery under test, experimental control area for test equipment storage area and the related personnel activity area. At the same time set up between the two with hole explosion, fire partition, to ensure the safety of the site. In the process of inspection, technical personnel can probe control device, or through the baffle hole extrusion plate to ensure the safety of the device itself.
