Foreword

GB/T 20234 “Connection Set of Conductive Charging for Electric Vehicles” consists of 3 parts. - Part 1.General Requirements; - Part 2.AC charging coupler; - Part 3.DC charging coupler. This Part is Part 2 of GB/T 20234. This Part was drafted in accordance with the rules given in GB/T 1.1-2009. This Part replaces "Connection Set of Conductive Charging for Electric Vehicles - Part 2.AC Charging Coupler" (GB/T 20234.2-2011). Compared with GB/T 20234.2-2011, the main technical changes are as follows. - The requirement “the rated current shall not exceed 32A” was modified to “the rated current shall not exceed 63A” (see Chapter 1); - 10A and 63A were added among the rated current values of charging coupler (see Table 1); - The function of spare contact was extended to three-phase charging function (see Table 2); - R4 resistance was added (see Figure 3); - The content of control pilot circuit and control principle was deleted (see Appendix A of 2011 edition); - Some dimensions of control pilot contact and mechanical lock of charging coupler were modified; drainage holes (optional) in socket were added; seal ring was modified as optional (see Appendix A); - The spatial size requirements of plug were modified and adjusted as a normative appendix (see Appendix C). This Part was proposed by the Ministry of Industry and Information Technology of the People's Republic of China. This Part shall be under the jurisdiction of the National Technical Committee on Automobiles of Standardization Administration of China (SAC/TC 114). Main drafting organizations of this Part.
