Champ d’application

This standard specifies the safety requirements for pure electric motorcycles and pure electric mopeds. It is mandatory for all manufacturers of electric two-wheelers entering the Chinese market. It covers general safety, electrical safety, operational safety, and marking requirements. It does not apply to hybrid motorcycles or non-electric variants.

Exigences techniques

The standard outlines comprehensive safety criteria across several domains. For electrical safety, it mandates strict requirements for power battery systems, including heat dissipation, installation integrity, and overcurrent/overheat protection. It specifies minimum creepage distances and electrical clearances to prevent arcing and short circuits. Regarding touch protection, the standard requires proper insulation and enclosure for live parts, especially for B-class voltage circuits. Manufacturers must ensure that high-voltage cables are distinctly colored orange and that insulation resistance exceeds 1000Ω/V. It also details the safety protocols for charging connections and overcurrent protection devices. For operational safety, the standard requires specific start-up sequences to prevent accidental activation. It mandates that the vehicle must not move when connected to a charging power source. When the driver leaves the vehicle in a 'drivable mode', an acoustic or optical warning must be triggered. It also sets requirements for low battery warnings, ensuring the vehicle can still travel at least 3km at 15km/h after the warning appears. Finally, the standard specifies marking and warning labels. High-voltage components must display a specific electric shock hazard symbol, and batteries must be clearly marked with their chemical type, nominal voltage, and rated capacity.

Méthodes d’essai

The standard defines several key testing procedures to verify compliance. Insulation resistance measurement is conducted under specific temperature and humidity conditions to ensure electrical safety. Dielectric withstand tests are performed on on-board chargers to verify insulation integrity under high voltage. Water protection tests are divided into car wash (IPX5), rain (IPX3), and wading tests to simulate real-world conditions. Additionally, potential equalization tests measure the resistance between exposed conductive parts, and a remaining capacity warning test verifies the vehicle's performance when the battery is low.

Questions fréquentes

What products are regulated under GB 24155-2020?

GB 24155-2020 applies to pure electric motorcycles and pure electric mopeds. It sets mandatory safety specifications for their electrical systems, operational features, and labeling.

Are there any updates from the previous version of GB 24155-2009?

Yes, the 2020 version introduces several updates, including new definitions for 'speed regulation unit' and 'on-board charger', added requirements for creepage distances and B-class voltage cable color, and updated testing methods for insulation resistance and water protection.

What are the key electrical safety requirements for B-class voltage circuits?

The standard requires that B-class voltage circuits have an insulation resistance greater than 1000Ω/V. Cables must be orange, and the system must automatically disconnect or reduce voltage/energy to safe levels within a specified time in case of a fault.

The summary above provides a high-level overview of GB 24155-2020.
