New GB/T 18488 Draft for the Testing Requirements of Drive Motor System for Electric Vehicles22. June 2023
The National Technical Committee for Automotive Standardization (also known as TC114) has announced a new draft status for the regulation of drive motor systems for electric vehicles. TC114 is under the Ministry of Industry and Information Technology (MIIT) and is essential for drafting new regulations for the automotive sector. The revised GB/T standards are GB/T 18488.1-2015 and GB/T 18488.2-2015. The title of the current draft is 20213563-T-339, and after further editing, it is to become the new version of the previously mentioned GB/T standards, therefore GB/T 18488-20XX.
Within the scope of the overall vehicle homologation in China, corresponding tests (MIIT or CCC) and labelling requirements are prescribed for electric motors and inverters. The new revision revises both the testing requirements and the marking requirements. Integrated drive systems are also included in the standard. These product categories require CCC certification for import and distribution in China.
Detailed information on the changes published so far can be requested from us. We will publish further details on the changes in the new version on our website as soon as they become available.
In order to implement the new standard, a transition period of 1 year is usually granted for existing drive motor systems. It is therefore purposeful to harmonize COP tests and new homologation tests for an implementation in e.g., 2024.
