Analysis of safety protection technology in the process of power lithium-ion battery testing

Analysis of safety protection technology in the process of power lithium ion battery detection [Abstract] In recent years, with the increasingly prominent social and environmental problems in my country, new energy vehicles have become more and more popular, and power lithium ion batteries have also been used in new energy vehicles. More and more frequently, its good quality and performance are an important guarantee for the safe operation of automobiles. Therefore, it is very important to do a good job of safety protection when testing power lithium-ion batteries. This article analyzes the safety protection technology of power lithium-ion batteries. [Keywords] power lithium-ion battery; detection; safety protection In recent years, my country's air pollution has been serious, haze weather has frequently appeared, urban pollution index exceeding the standard is very serious, and the lives and health of urban residents have been greatly threatened. According to the current rate of human consumption of coal, oil and other fuels, these fuels will be consumed within decades. Prior to this, the development of alternative energy sources to drive cars was the focus of research. 1. The development trend of power lithium-ion batteries The current nickel-hydrogen power lithium-ion battery technology is the most mature, most successful commercialization, and the most widely used type of power lithium-ion battery, [1] but the effective battery technology has been Reaching the limit, with the rapid development of science and technology, lithium batteries have won most manufacturers in vehicles with their superior performance in this field. It is believed that in the near future, they will gradually replace nickel-metal hydride batteries, and lithium batteries have become the current era. The mainstream and future research directions in the automotive field. Regardless of the power lithium-ion battery, in order to ensure its good application performance, effective safety protection techniques and measures should be taken during testing. 2. Check the safety protection technology of power lithium-ion batteries In recent years, people's environmental awareness has gradually increased. At this time, power lithium-ion batteries are favored by automakers due to their strong environmental performance. Therefore, it is very important to improve the detection safety of power lithium-ion batteries, especially nickel-hydrogen power lithium-ion batteries. In other words, certain safety protection technology should be adopted to ensure that the power lithium-ion battery is tested in a safe environment. 2.1 Strengthen personnel training and improve the comprehensive quality of testing personnel. The testing of power lithium-ion batteries requires corresponding testing personnel with high psychological quality, not only professional technical knowledge and rich on-site related experience, but also a high sense of responsibility And serious work attitude. Therefore, on the one hand, relevant departments should strengthen the training of all aspects of testing personnel, actively organize various training activities, and at the same time conduct professional knowledge learning for testing personnel from time to time. For some people, on the other hand, for young workers with high enthusiasm and strong absorptive capacity, the relevant departments can provide personnel who have the opportunity to go abroad, so that they can learn advanced foreign science and technology and field-related experience, and at the same time communicate with my country Lithium-ion batteries, combined with innovations based on detection technology and methods, create a display of the characteristics and methods of my country's power lithium-ion battery safety testing technology to ensure the safety of the power lithium-ion battery testing environment. In addition, the maintenance personnel should inspect and repair the equipment in time, and keep a record of the inspection. Report the problem to the superior department in a timely manner. If the experimental equipment has a major failure, after the failure is eliminated, it must be identified or accepted before it can be used. At the same time, in order to increase the safety factor of work, relevant departments should also increase equipment investment and promptly introduce foreign advanced power lithium-ion battery testing equipment. 2.2 Perform area tests and install necessary protective facilities. When testing power lithium-ion batteries, if you do not pay attention, it is easy to cause explosion and fire. In order to prevent the occurrence of such dangerous situations, the test site should be divided into two parts: the sample test area and the test control area. The sample experiment area is the storage area of u200bu200bthe power lithium-ion battery to be tested, and the experiment control area is the area where the test equipment is placed and the activity area of u200bu200brelated personnel. At the same time, an explosion-proof and fire-proof partition wall with holes is set between the two to ensure the safety of the site. During the inspection, the technician can control the device through the probe or squeeze the drop plate through the hole of the baffle to ensure the safety of the device itself.
