6.2.3 Estimated energy cost The OVC-HEV estimated energy cost is calculated in accordance with Formula (2). The data shall be rounded (off) to two decimal places: Where, CH

---the estimated energy cost, expressed in (yuan/100 km); FH

---the "OVC-HEV fuel consumption" type certification value, expressed in (L/100 km); PF

---the estimated fuel price, for gasoline, take 7.502), for diesel, take 7.002), expressed in (yuan/L); EH

---the "OVC-HEV electric energy consumption" type certification value, expressed in (kW h/100 km); PE

---the estimated electricity price, take 0.662), expressed in [yuan/(kW h)].

6.2.4 CO

2 Emission 4) The method refers to the simple conversion method, and the conversion method will be updated in a timely manner in accordance with the actual situation. The OVC-HEV electric energy consumption and OVC-HEV fuel consumption used for the comprehensive converted fuel consumption from oil and electricity are type certification values. The CO2 emission data refers to the CO2 emission calculated through the conversion formula in GB 19578 in accordance with the "OVC-HEV fuel consumption" type certification value determined in accordance with GB/T 19753-2021. The data shall be rounded (off) to two decimal places.

6.2.5 Electric driving range The electric driving range data of Category-M1 vehicles refers to the driving range calculated in accordance with GB/T 32694. The electric driving range data of Category-N1 and M2 vehicles refers to the driving range5) determined in accordance with the corresponding test method in GB 20997. The data shall be rounded (off) to an integer.

7.1 Division of Functional Areas

7.1.1 Overview The label consists of four functional areas: "title area", "information area", "description area" and "additional information area". See Figure B.1 ~ Figure B.4 in Appendix B.

7.1.2 Title area The "title area" is located at the top of the label, with "enterprise label" on the left and "label "AUTOMOBILE ENERGY CONSUMPTION LABEL" in capital letters in English, which are arranged with Chinese at the top and English at the bottom.

7.1.3 Information area

7.1.3.1 The "information area" is divided into two parts: "basic information area of model" and "energy consumption information area". The "basic information area of model" is located in the upper part of the information area, and the "energy consumption information area" is located in the lower part of the information area, which is the core part of the label. The fuel consumption, estimated energy cost and CO2 emission information are located in the upper part of the "energy consumption information area", the driving range information is located in the lower part of the "energy consumption information area".

7.1.3.2 For BEV, the "basic information of model" includes the manufacturer, vehicle model, engine model, energy type, drive motor peak power, complete vehicle curb weight, maximum design total mass and other fuel consumption-related information that the enterprise needs to explain. If no other information is provided, the "other information" does not need to be labeled. For OVC-HEV, the "basic information of model" shall also include engine model, displacement, maximum net power of engine and transmission type. 5) The driving range is consistent with the relevant requirements for vehicle type certification. CO2 emission: . g/km The electric driving range information is located above the driving range horizontal line, as shown in EXAMPLE 6. EXAMPLE 6: Electric driving milage: km

7.1.4 Description area

7.1.4.1 The "description area" is located at the bottom of the label. The left side of the "description area" is a QR code; the middle is the national standard (including year number and title) adopted for the fuel consumption and driving range tests, as well as energy prices, and factors affecting fuel consumption, driving range and energy cost; the right side is "label category pattern" shown in Figure B.11 and Figure B.12.

7.1.4.2 For BEV, the specific content of the middle part of the "description area" is as follows:

---The electric energy consumption and driving range data used for this label is determined in accordance with GB/T 18386.1-2021 Test Methods for Energy Consumption and Range of Electric Vehicles - Part 1: Light-duty Vehicles. The calculation of estimated energy cost is based on electricity price . yuan/kilowatt hour. NOTE: 1 kilowatt hour = 1 kW h.

---Due to the influence of factors, such as: driving habits, road conditions, climatic conditions and electricity price, etc., the actual data may differ from this label.

---To prevent the label from affecting the vision, please remove the label after purchasing the vehicle.

7.1.4.3 For OVC-HEV, the specific content of the middle part of the "description area" is as follows:

---The fuel consumption, electric energy consumption and driving range data used for this label is determined in accordance with GB/T 19753-2021 Test Methods for Energy Consumption of Light-duty Hybrid Electric Vehicles. The calculation of estimated energy cost is based on gasoline . yuan/L, diesel . yuan/L and electricity price . yuan/kilowatt hour.

---Due to the influence of factors, such as: driving habits, road conditions, climatic conditions, fuel quality and energy price, etc., the actual data may differ from this label.

---CO2 is one of the main greenhouse gases.

---To prevent the label from affecting the vision, please remove the label after purchasing the vehicle.
