The Equipment Industry Department of the Ministry of Industry and
Information Technology organized the National Automobile Standardization
Committee to compile the key points of new energy vehicle standardization work
in 2019. The work points clarified five key research areas, including electric
vehicle safety, electric vehicle energy consumption, fuel cell electric
vehicles, charging facilities and hydrogenation systems, and power battery
recycling.
The work points point out that the new energy vehicle standard system must
be continuously optimized. Establish a system framework that coordinates
mandatory and recommended national standards for new energy vehicles, accelerate
the construction of standard subsystems such as fuel cell electric vehicles and
power battery recycling, and formulate the "New Energy Vehicle Industry
Development Plan (2021-2035)" Taking this opportunity, we will conduct in-depth
research on the integration development trends of new energy vehicles and
energy, transportation, communications, etc., and continuously optimize and
improve the new energy vehicle standard system.
At the same time, the work points also pointed out that the electric
vehicle standardization roadmap must be updated in a timely manner. According to
the current status of industrial development and actual needs, and combined with
the progress of standard projects under development, the "China Electric Vehicle
Standardization Work Roadmap" will be revised in a timely manner to maintain
timeliness, scientificity and accuracy, and continue to play the roadmap's basic
supporting role in the standard system.
The work points pointed out that key areas should be studied to meet the
needs of industrial development. The work points clarified five key areas:

In addition, the work points emphasize the need to strengthen international
participation and enhance international influence:
The first is to deeply participate in the formulation of global technical
regulations. Fulfill the duties of vice chairman of the working groups on
electric vehicle safety (EVS), electric vehicles and the environment (EVE) and
fuel cell electric vehicles (HFCV) under the framework of the United Nations
World Vehicle Coordination Forum (WP29), and continue to be deeply involved in
the third session of electric vehicle safety Research and verification of global
technical regulations such as Phase II and hybrid vehicle power test methods,
and organize and host the sixth fuel cell electric vehicle working group
meeting.
The second is to actively participate in international standardization
work. Systematically participate in the formulation and coordination of
international standards for electric vehicles under the framework of the
International Organization for Standardization (ISO) and the International
Electrotechnical Commission (IEC), actively organize and convene expert meetings
for international standard registration, organize the development of
international standard proposals, and continuously increase my country's efforts
in electric vehicles. Participation in relevant international standards such as
conductive charging, wireless chargers and electric motorcycles.
The third is to continue to strengthen international exchanges and
cooperation. Utilize established bilateral cooperation mechanisms such as
China-Europe, China-Germany, China-France, China-Japan, etc., as well as
multilateral exchange platforms such as APEC and the “Belt and Road Initiative”
to continue to strengthen research and development in key areas such as electric
vehicle safety, energy consumption, key components and charging infrastructure.
Exchange and cooperation, jointly carry out relevant technical research and
testing verification work, and support the coordinated advancement of domestic
standards and international standards and regulations.
