One article takes you to know the safety of lithium batteries

Knowing that the safety of lithium batteries is of the utmost importance, the power and starter batteries of the E6 battery for electric vehicles are powered by the et-power iron battery developed and processed by BYD. This technology represents the advanced level of today's world. In terms of environmental protection, it will not cause any harm to the environment, and all the chemical substances it contains can be distinguished and absorbed by the environment in a harmless way. The E6 group has a power of 90KW and a torque of 450Nm, with very good performance. It has a top speed of 140 kilometers per hour and a maximum range of 300 kilometers, which is the best in this category. Although the cause of the accident is not yet clear, discussions around the development and future of electric vehicles continue to heat up. Wang Zidong, director of the National 863 Electric Vehicle Severe Battery Inspection Center of the Northern Automotive Research Institute of my country, pointed out that the center has performed kneading and crash tests on Yadi’s electric vehicles, and the battery module did not catch fire after being deformed by 50%. But this is only carried out at a speed of 50 km/h, which is the American standard, not at a speed above 100 km/h. Witnesses at the time stated that the vehicle was traveling at a speed far exceeding 100 kilometers per hour, which indicated that the battery testing standards for electric vehicles should be improved. Lin Cheng, deputy director of the National Electric Vehicle Engineering Laboratory, made it clear: This work will have a serious impact on my country's electric vehicle and battery industries, but we can't just focus on power lithium-ion batteries. Now it seems that the situation is still very complicated. In fact, after so many years of development of gasoline vehicles, this has happened more than once. The technology of electric vehicles is still in the development stage. The media should not draw conclusions prematurely and mislead the public. A professional expert said that neither the lithium iron phosphate battery nor the lithium manganese oxide battery fundamentally solves the safety problem. Factors that threaten the safety of electric vehicles include energy density, discharge power, packaging of battery packs, and high voltages caused by collisions. So far, there is no technology in the world that can fundamentally solve these problems. Regarding the BYD E6 accident, some experts pointed out that the mass-produced car was in the testing stage than the test car, and the rear bumper at the rear of the body was not strong enough. Because all the 90et-power iron batteries are arranged on the chassis of the car, the body is only 15cm high from the ground by a fist, which unpreventably increases the risk. In addition, due to their own life-saving electric vehicles, safety awareness is not known, and many people are afraid of the explosion risk of lithium batteries, which constitutes a traffic accident and pedestrians are afraid to save close rescues, so it is a very important promotion.
