At the meeting, Xu Haidong, deputy chief engineer of the China Association of Automobile Manufacturers, delivered a speech. He said that with the new The energy vehicle industry is developing rapidly, and the quality and performance of new energy vehicle products in complex and extreme environments have received widespread attention. At present, the industry has not yet established a scientific and complete performance evaluation system for intelligent new energy vehicles in complex extreme environments. China Automotive Research Institute organized a special seminar on extremely complex environmental evaluation technology for intelligent new energy vehicles, which is of great practical significance for formulating relevant standards and standardizing automobile evaluation work in the future.

Peipei, Director of China Automotive Engineering Research Institute Co., Ltd. and Director of the Index Management Center, delivers a speech , she pointed out that in recent years, our country has deeply promoted the national strategy of new energy vehicles and implemented top-level design, policy preferences and fiscal and tax subsidies. The new energy vehicle industry has entered a period of comprehensive market expansion, and technologies have continued to mature and make breakthroughs. While the new energy automobile industry is developing rapidly, it is also facing new issues of high-quality development. Research on complex and extreme environmental evaluation standards for new energy vehicles urgently needs to be launched to support the healthy development of the automotive industry and provide scientific guarantee for consumers' transparent and reasonable consumption.

Let’s discuss together Research, complex extreme environment assessment research helps industrial upgrading

At the meeting, China Automobile Research Institute released the "China Automobile Research Institute New Energy Vehicle Energy Efficiency Research Report". Through verification of more than 50 pure electric passenger vehicles in the past five years, it was found that the energy efficiency level of new energy vehicles has improved year by year. Specifically, In terms of charging time per 100 kilometers, low-temperature range degradation rate, and power consumption per 100 kilometers at normal temperature, problems such as "low-temperature range degradation" and "temporary power replenishment difficulties" that have troubled consumers are being solved, and some outstanding products in the industry have levels increased to 22.3% and 8min respectively.

Combining social hot spots and industry pain points, China Auto Research also produced a report on "Evaluation Research of Intelligent Driving Systems in Complex Climate Environments and Dangerous Scenarios." China Automotive Research Institute will build a rain and fog simulation test meteorological environment based on the basic scene database and refer to the national meteorological standards. At the same time, it will independently develop highway construction operating vehicle targets to form real vehicle test cases of complex weather environments and dangerous scenes with high degree of restoration and rapid construction. The database is used to evaluate relevant popular models and publish evaluation results, provide consumers with a scientific and objective reference for car selection, improve the evaluation procedure system in complex environments and dangerous scenarios, and professionally assist enterprises in technological innovation and industrial upgrading.
