Four national standards for electric vehicles introduced

Recently, it was learned from the National Automobile Standardization Technical Committee that at the Chongqing Conference held by the Standardization Technical Committee Electric Vehicle Sub-Technical Committee at the end of April, “Conducted Charging Interface for Electric Vehicles”, “General Requirements for Electric Vehicle Charging Station” and “Electric Vehicles” The four protocols, "Communication Protocol between Battery Management System and Off-board Charger" and "Test Method for Energy Consumption of Light-duty Hybrid Electric Vehicles," passed the review and became the "national standard" for electric vehicles.

New energy vehicles to usher in the "standard" Time <br> <br> Up to now, China has formulated and promulgated the new energy vehicles to national standards and industry standards totaled 42, of which 22 have been classified as new energy automotive products access Special inspection standards.

It is reported that after the "Electric Vehicle Conductive Charging Interface" and other four standards become national standards, there will be "fuel cell electric vehicle hydrogen filling port", "car-mounted hydrogen system technical conditions", "fuel cell electric vehicle maximum speed test method New energy vehicle standards, such as the "Method for Measuring the Hydrogen Consumption of Hybrid Electric Vehicles for Fuel Cells," and others have been introduced.

The construction of charging facilities is inseparable from the standards and guidance of relevant standards. In the early stage of the promotion of electric vehicles, the country’s encouraging policies will play a crucial role.

The expert said that the “Electric Vehicle Conductive Charging Interface”, “General Requirements for Electric Vehicle Charging Stations” and “Communication Protocols between Battery Management Systems for Electric Vehicles and Non-vehicle Charging Machines” that were issued as national standards at the end of April were Car charging is closely related to important standards. The “Test Method for Energy Consumption of Light-duty Hybrid Electric Vehicles” lays the foundation for scientifically evaluating the energy consumption of this type of hybrid vehicle.

It is reported that for the current electric vehicle charging station has not yet formed a unified business model, vehicle charging mode and split box charging mode have a certain degree of development prospects, the introduction of the "General Requirements for Electric Vehicle Charging Station" covers different charging Common parts of the model include requirements for charging, power supply, monitoring, metering, and so on. Specific requirements for specific modes (such as the possibility of battery replacement at venues and equipment in a split-box charging mode) and some extended functions of the charging station (such as battery detection, etc.) will be stipulated separately.

International standards will become an important reference
<br> <br> experts said on electric vehicle charging station, charging interface and communication protocols, international standards are being worked out, but the process is slower than the Chinese national standard rate, China will become the national standard relevant international standards Important reference.

Relevant experts also stated that the implementation of the above-mentioned national standards is also one of the important basis for public attention on whether new energy vehicles can receive subsidies.

Experts of the electric vehicle sub-committee said that "the above standards will be used for electric vehicle industry management and related subsidy policies."
