Electric vehicle conductive charge coupler 1 Scope This standard specifies the terminology and definition, technical parameters, charging mode, classification and functional definition, structural dimensions, performance requirements, test methods and inspection rules for the conductive charge coupler of electric vehicles. The standard specifies two kinds of charge couplers. one is to provide AC power supply to the on-board charger AND the other is to provide DC power supply to the electric vehicles. This standard applies to the charging cables of AC rated voltage 220 V AND DC rated voltage not exceeding 750 V which are used for the electric vehicles as well as the conductive charge coupler used at the connection side of the electric vehicle; the conductive charge coupler used between the charging cable and the off-board charging equipment or AC power supply can make reference to this standard. 2 Normative references The provisions in following documents become the provisions of this Standard through reference in this Standard.

The protective cover shall have a fixed connection between its parts and accessories (such as chains, ropes, etc.) AND it shall not be able to be disassembled without the use of tools. 8.1.3 The enclosures of the connector and the inlet shall be marked with the manufacturer's name or trademark, product type, rated voltage and rated current. 8.1.4 The terminals of the connector and the inlet shall be marked with the symbol as specified in 4.2. 8.1.5 After the inlet is installed on the electric vehicle, its marking of the rated voltage and the rated current shall be easily identifiable. 8.1.6 Color marking of charging mode. In the distinct area of the connector (e.g. the control button surface of the locking device), it shall use different colors to represent different charging modes. - Blue. Charging mode 1; - Green. Charging mode 2; - Yellow. Charging mode 3; - Red. Charging mode 4. 8.1.7 Locking device. The charge coupler shall have a lockout function to prevent accidental disconnection during charging process. In the locked state, when applying twice The force used in the entire process to insert and extract the charge connector into/out of the power inlet AND the vehicle connector into/out of the vehicle inlet shall comply with the requirements below. - As for the AC charge coupler, it is less than 100N; - As for the DC charge coupler, it is less than 140N. The charge coupler can use the booster; AND if the booster is used, when conducting insertion and pull-out operation, the operating force of the booster shall satisfy the aforementioned conditions. 8.1.11 Breaking capacity. 8.1.11.1 As for the AC charge coupler which has the control guidance AND is free from unload breaking during normal operation, if conducting test in accordance with 9.7, it shall not cause the risk of fire or electric shock; after the test is finished, it is not required for the device to maintain the original functions. As for the DC charge coupler which has the control guidance AND is free from unload breaking during normal operation, it does not require breaking capacity test. 8.1.11.2 In the case of a charge coupler which does not have the control guidance function OR the control guidance circuit cannot avoid loaded breaking, when conducting test in accordance with 9.7, after the test, the sample shall be free from damages which is detrimental to the continued use. 8.1.12 Protection degree. 8.1.12.1 When the connector and inlet are neither engaged nor protectively covered, the protection degree shall be not less than IPXXB. 8.1.12.2 After connecting with the protective cover, the degree of protection of the connector and the inlet shall respectively reach to IP54. 8.1.12.3 After the connector and the inlet are engaged, the degree of protection shall respectively reach to IP55. 8.1.13 Mechanical strength.
