Escopo e aplicabilidade

This standard specifies the energy consumption label requirements for light-duty vehicles. It specifically applies to M1, M2, and N1 category vehicles with a maximum design total mass not exceeding 3500 kg, covering both off-vehicle-chargeable hybrid electric vehicles (OVC-HEV) and battery electric vehicles (BEV). Manufacturers must comply with this standard to affix proper energy consumption labels on applicable vehicles. This is Part 2 of the GB 22757 series.

Requisitos técnicos

The standard outlines the content, format, material, and affixing requirements for vehicle energy consumption labels. For BEVs, the label must include electricity consumption, equivalent fuel consumption, estimated energy cost, and driving range. For OVC-HEVs, it must additionally specify fuel consumption, CO2 emissions, and electric driving range. Manufacturers are required to display estimated energy costs based on specific calculation formulas provided in the standard. The label is divided into four functional zones: title, information, explanation, and additional information. Furthermore, the standard introduces requirements for electronic labels (e-labels) in Annex A, detailing the carrier specifications and digital data presentation. Both physical and electronic labels must adhere to strict formatting, color, and font size specifications.

Métodos de ensaio

The energy consumption and driving range data presented on the labels must be obtained through specific type-approval testing methods. For BEVs, testing is conducted according to GB/T 18386.1-2021, which measures energy consumption and driving range under various conditions, including low-temperature heating and high-temperature cooling scenarios. For OVC-HEVs, fuel consumption, electricity consumption, and electric range are determined based on GB/T 19753-2021. The equivalent fuel consumption conversion follows the methods outlined in GB/T 37340.

Perguntas frequentes

What products are regulated under GB 22757.2-2023?

It regulates light-duty vehicles (M1, M2, and N1 categories with a max mass of 3500 kg) that are either battery electric vehicles (BEV) or off-vehicle-chargeable hybrid electric vehicles (OVC-HEV).

Are there any updates from the previous version of GB 22757.2?

Yes, compared to the 2017 version, this update introduces estimated energy cost calculations, CO2 emission data for OVC-HEVs, and new requirements for electronic labels. It also updates the data acquisition methods for energy consumption and driving range.

Does this standard specify the actual energy consumption limits for vehicles?

No, GB 22757.2-2023 focuses on the labeling requirements—the content, format, and presentation of energy consumption data. The actual fuel consumption limits are specified in separate standards such as GB 19578 and GB 20997.
