Electric vehicle industry chaos will end

Even the GM Chevrolet Volt, one of the more mature mass-produced electric vehicles in the industry, has shown potential safety hazards, casting a shadow over the global new energy automotive industry.

In the Chinese market in particular, almost all automakers hope to take advantage of the new energy vehicle project. However, because the industry itself has not yet formed a norm in the research, development, production, and battery management of electric vehicles, mixed companies are flooded throughout the industry. , The safety of electric vehicle products is worrying.

Recently, it was learned from related departments that the next year will be the time for the introduction of China's electric vehicle safety standards. This will play a role in clearing the industry chaos.

Frequent safety hazards In May of this year, a Volt EV battery was damaged during the impact test. Three weeks later, the battery ignited, igniting the car and the other three cars in the garage. This prompted the National Highway Traffic Safety Administration NHTSA to investigate the safety of Volt electric vehicles at the end of November.

Chinese consumers are no strangers to electric vehicle safety accidents. In April of this year, an electric taxi produced by a Zotye automobile spontaneously ignited on the streets of Hangzhou.

Not only that, in the cities of Shandong, Jiangsu and other provinces where low-speed electric vehicles are prevalent, due to the incompatibility of electric vehicle batteries, there have been two cases of driver deaths.

"The biggest feature of electric vehicles is that they have a battery system, a set of high-voltage systems, and there is potential danger in high-voltage batteries." Chief Engineer, Institute of Automotive Standardization, China Automotive Technology and Research Center (hereinafter referred to as "China Automobile Center") Zhou Rong thinks.

According to Zhou Rong's analysis, the hidden dangers in the safety of electric vehicles are mainly concentrated in four aspects: high-energy power batteries have potential for burning; electric vehicles have high-voltage, high-current loops; if human contact can cause harm; Because the quality of electric vehicles is about 200kg more than that of traditional cars, the damage caused to people is extremely great; finally, the impact of battery waves on the human body is the last, and the electric vehicle's transmission power is tens of thousands of times that of mobile phones.

Collision Criteria and International Synchronously From the current industrial development process, electric vehicles have encountered various problems in the process of promotion and application. The most important issue is that the battery problem does not break through to fully meet the needs of automobiles.

The temptation of the new energy concept's huge interest has led to the emergence of hundreds of automotive battery manufacturers in the country in the past few years. Due to low battery entry barriers, the industry has become a mixed presence, and there are many problems in quality supervision, sales, and recycling supervision. Loopholes.

“There are three safety standards relating to electric vehicles that are currently in use in China. They are aimed at vehicle-mounted energy storage devices, functional safety and fault protection, and personnel protection against electric shock. However, these three standards for electric vehicles were all enacted in 2001. The level of scientific research at the time has now been over 10 years and many aspects have fallen behind.” Zhou Rong said frankly.

The failure of the industry standards to advance with the times is one of the important reasons for the chaos in the electric vehicle industry. However, the situation where the policy is not in place will probably improve next year.

According to Zhou Rong, safety standards for electric vehicles are now being revised and revised versions will be completed and announced next year. "In particular, according to the development of battery technology in recent years, some content has been added."

In fact, in the formulation of safety collision standards for electric vehicles, our country’s progress is almost in sync with international authorities. It is reported that China Automobile Center is doing a separate standard for electric vehicle collisions. It has already set up a project and plans to finish it next year. "The standardization international organization ISO is also doing research on the standardization of electric vehicle safety collision in August this year, so our country is in sync with the international in this respect." Zhou Rong said.

It is worth mentioning that China is the first country in the world to put forward the safety requirements for fuel cell vehicles (GB/T24549-2009). Many of the fuel cell safety regulations to be promulgated by international agencies will be elements from China.
