A few days ago, the National Road Transport Standardization Technical Committee announced the "Electric Operations Cargo Vehicle Selection Technical Requirements", and disclosed opinions (hereinafter referred to as the opinion). The opinions have made new requirements for the appearance of electric operating trucks, load quality utilization factors, environmental adaptability, contingent mileage and economic, and charging. Among them, the opinion will be adjusted at the current phase of electric operating trucks produced at the current phase of automobile enterprises in accordance with the cost of the load.

The opinion is based on the actual needs of electric operating trucks and the technical level of the production company, which determines the standard range, which specifies the selection requirements and test methods of electric operating trucks. It is suitable for driving by motor, and drives electric energy storage. System (Ress) pure electric N1, N2, N3 operated cargo vehicles, not suitable for fuel power lithium battery vehicles.

In terms of load quality utilization factors, the opinion is analyzed by analyzing the distribution of electric operating truck quality utilization factors, according to the different types of vehicles, with a maximum of about 30%, and the main model of load quality utilization factor is proposed. Require. See the figure below: The opinion is done in the environmental adaptability, renewal mileage and economy.

According to the draft, the vehicle's power lithium-ion battery needs to meet the electric vehicle for lithium ion power storage packages, system (GB / T31467) and electric vehicle power storage battery safety requirements and test methods (GB / T31485). In terms of environmental adaptability, the opinion proposes the high and low temperature adaptability of electric operating trucks to meet the vehicle should be able to start and travel normally at ¡ã C in (-20 ~ 45). When high temperature is charged, the power battery is not less than 90% of the battery power (nominal); when charging is charged, the power storage battery is not less than 80% of the battery power (nominal).

According to GB / T31486-2015 Electric vehicle power battery electrical performance requirements and test requirements for battery modules: 1C discharge capacity at -20 ¡À 2 ¡ã C is not less than 70% of the initial capacity; 1C at 55 ¡À 2 ¡ã C The discharge capacity is not less than 90% of the initial capacity; after the 100% SOC at 55 ¡À 2 ¡ã C is stored for 7 days, the charge retention ratio is not less than 85% of the initial capacity, and the capacity recovery should not be less than 90% of the initial capacity. In terms of renewal mileage, the comment shows that the renewal mileage of the electric operating truck is requested, and the N1 types of vehicles are tested in accordance with GB / T18386 working conditions, N2, and N3 vehicles are tested in accordance with GB / T18386. Renewal mileage should not be less than 200km.

In terms of economic, the opinion is based on the subsidy policy, the two indicators of the quality energy density of the dynamic lithium-ion battery system and the unit load quality energy consumption (EKG) are sharpened to 95WH / kg and 0.45Wh / km ¡¤ kg. In addition, the opinion is also stricter and meticulous regulations in the dynamic, reliability and charging of vehicles.

"Electric Operation Cargo Vehicle Selection Technical Requirements", according to the 2017 Transportation Standardization Program related work requirements, the research work of the Ministry of Transportation Department and the Ministry of Transportation Science and Transportation Department. The draft grass group analyzed all electric operating truck data in 2017 in 1 to 9 recommended catalog models in 2017, from the actual needs of road cargo transportation, and finally drafted from the actual demand of road cargo transportation. This comment for the comments.

The draft grass group believes that the current pure electric freight vehicle is still important for urban logistics distribution, the average mileage demand is generally around 150 ~ 180km, and the mileage 200km can meet the Operational needs of most transportation companies. Transport vehicles charge once a day, which is conducive to extending battery life and maintains urban power grid balance. The draft grass group pointed out in the preparation description, according to the current requirements of my country's new energy vehicle promotion application subsidy policy, evaluating the economy of electric operating truck, including loading power lithium-ion battery system quality energy density and EKG two indicators.

Through the statistics of the dynamic lithium ion battery system of all electric operating trucks in the recommended directory model in 2017, there is currently 92.7% of the power-based dynamic lithium-ion battery system in electric operating trucks. That is equal to 95WH / kg, as shown in Figure 2.

About 85.7% of the EKG is less than or equal to 0.45WH / km ¡¤ kg, as shown in Figure 3.

Therefore, the opinion on the quality energy density of the power lithium ion battery system and the EKG two indicators are improved to 95WH / kg and 0.45Wh / km ¡¤ kg are relatively reasonable. China.

com believes that the relevant requirements of "Electric Operation Cargo Vehicle Selection Technical Requirements" will have a certain impact on future electric operating truck market, and the dynamic lithium-ion battery company should make adjustment preparations in related supporting products. In 2017, my country's pure electric operating truck market has been developed rapidly. The power lithium-ion battery company has also added to the electric operation truck market.

However, there are also industry insiders revealed that the quality of electric operating trucks is uneven, some low-quality power lithium-ion batteries flow into electric operating truck market, and become one of the hidden dangers of my country's new energy vehicles. By adjusting the technical adjustment of electric operating trucks, it is conducive to the development of a good ecology to the industry, promoting the development of my country's new energy automotive industry. From the adjustment detail, the low-end electric operating truck faces a large pressure, according to 30% phase-out indicators, the market share of the battery company will change, and some company market shipments will be cut.

From another aspect, the technical adjustment of electric operating truck will increase the transition pressure of partial powered lithium-ion battery companies, and accelerate the elimination of low-end production of dynamic lithium-ion battery.
