CQC: New GB-Standard for Voluntary CQC Mark Certification of Connection Set for Conductive Charging of Electric Vehicles

2. May 2016

As previously announced, the SAC (Standardization Administration of the People’s Republic of China) and AQSIQ (General Administration of Quality Supervision, Inspection and Quarantine of the People’s Republic of China) jointly issued a new GB-standard GB/T18487.1-2015 “Conductive Charging Systems for Electric Vehicles – Part 1: General Requirements” in their announcement No. 40 from December 28, 2015. It was implemented on January 1, 2016.

At the same time the Chinese authorities also announced a new GB standard for the Voluntary CQC Mark Certification for the connection set for conductive charging of electric vehicles, which was also implemented on January 1, 2016.

This new GB standard consists of GB/T 20234.1-2015, GB/T 20234.2-2015 and GB/T 20234.3-2015, which are replacing the old versions from 2011.

The main technical changes are as follows:

GB/T 20234.1-2015 “Connection set of conductive charging for electric vehicles – Part 1: General requirements”:

  • Added 1000V (DC) in rated working voltage (preferred value) as well as 10A (AC), 80A (DC) and 200A (DC) in rated working current (preferred value).
  • Deleted the requirement that connection set for charging of which the rated working current exceeds 16A (not including 16 A) shall be equipped with control pilot circuit.
  • Modified the protection requirements of power interface and vehicle interface.
  • Made clear that electronic locking device shall be installed on vehicle plug of DC charging interface.
  • Modification of some test parameters of test methods.

GB/T 20234.2-2015 “Connection set for conductive charging of electric vehicles – Part 2: AC charging coupler”:

  • Increased the requirement that the rated current shall not exceed 63A, from 32A before.
  • 10A and 63A were added among the rated current values of charging coupler.
  • The function of spare contact was extended to three-phase charging function.
  • R4 resistance was added.
  • The content of control pilot circuit and control principle was deleted.
  • The spatial size requirements of plug were modified and adjusted as a normative appendix.

GB/T 20234.3-2015 “Connection set for conductive charging of electric vehicles – Part 3: DC charging coupler”:

  • 80A and 200A were added among the rated current values of charging coupler.
  • The coupling order of contacts in the charging connection process was adjusted, and electronic locking device was added in the schematic diagram for connection interface.
  • Some dimensions of control pilot contact and mechanical lock of charging coupler were modified.
  • The spatial size requirements of plug were modified and adjusted as a normative appendix.

Since this announcement manufacturers can apply for certification in accordance with the new GB-standard or apply for the update of existing certificates with the CQC.
