On June 11, 2024, No. 1 Equipment Department of the Ministry of Industry and Information Technology (MIIT) and Science and Technology Department of the National Energy Administration (NEA) organized experts and has formulated the draft of national mandatory standard Safety requirements for electric vehicle conductive charging system (standard project no. 20240614-Q-624, hereinafter referred to as “the Standard”) and therefore called for public comments. The deadline for submitting feedback was July 8, 2024.

The Standard project is approved on March 25, 2024, and it covers 9 chapters and 1 normative annex. It specifies the general safety rules of electric vehicle conductive charging system, charging interface safety, AC charging safety, DC charging safety as well as the corresponding test methods and implementation transition period.

Once implemented, it will apply to electric vehicle AC and DC charging systems, the rated voltage of the power supply network side does not exceed 1000 V AC or 1500 V DC, the rated maximum voltage of the electric vehicle side does not exceed 1000 V AC or 1500 V DC. The Standard is also suitable for the charging safety requirements in the charging and discharging system of electric vehicles. However, it does not apply to:

- Safety requirements related to the maintenance of conductive charging/charge-discharge systems for electric vehicles;

-- Automatic charging system such as top contact charging system etc.;

-- On-bard vehicle charging equipment specified in national standard GB/T 40432 Conductive on-board charger for electric vehicles.

The transition period plan currently stated in the Standard is that once it is implemented:

·         New type approval applications for electric vehicles and power supply equipment shall be conformed with this Standard after its implementation date.

·         For electric vehicles that have received type approval and for power supply equipment that has obtained type test reports, the implementation shall start from the 13th month from the implementation date of the Standard.

For foreign stakeholders and MNCs, another important information of this standard is that it uses ISO and IEC relevant standards, including but not limited to the IEC 61851 series Electric vehicle conductive charging system, ISO 17409 Electrically propelled road vehicles — Conductive power transfer — Safety requirements and ISO 5474 series Electrically propelled road vehicles — Functional and safety requirements for power transfer between vehicle and external electric circuit have been used as reference during the standard drafting, yet no direct adoption has been performed. It may cause a bigger impact in terms of conformity comparing with those that adopted international standards.
