The high-voltage connector has a mechanical locking relationship with some other mechanism. Before the high-voltage connector is opened, the locking mechanism can only be opened by using tools; or c) After the high-voltage connector is separated, the voltage of the live part of the connector can, within 1 s, be reduced to not more than 30 V (a.c.) (rms) and not more than 60 V (d.c.). 5.1.3.4 Requirements for high-voltage service disconnect For vehicles equipped with a high-voltage service disconnect, the high-voltage service disconnect shall not be opened or pulled out without tools, except for the following two cases: a) After the high-voltage service disconnect is opened or pulled out, the live part of the class B voltage meets the requirements for degree of protection of IPXXB specified in GB/T 4208-2017; or b) Within 1 s after separation, the voltage of the live part of the class B voltage of the high-voltage service disconnect drops to not more than 30 V (a.c.) (rms) and not more than 60 V (d.c.) 5.1.3.5 Requirements for charging socket When the vehicle charging socket and the vehicle charging plug are disconnected, the vehicle charging socket shall meet at least one of the following requirements: a) Within 1 s after disconnection, the voltage of the live part of the class B voltage of the charging socket drops to no more than 30 V (a.c.) (rms) and no more than 60 V (d.c.); or the total energy stored in the circuit is less than 0.2 J; or b) When meeting the requirements for degree of protection of IPXXB specified in GB/T 4208-2017 and within 1 min, the voltage of the live part of the class B voltage of the charging socket drops to no more than 30 V (a.c.) (rms) and no more than 60 V (d.c.); or the total energy stored in the circuit is less than 0.2 J. 5.1.4 Requirements for protection against indirect contact 5.1.4.1 Requirements for insulation resistance Under the maximum working voltage, the insulation resistance of the d.c. circuit www.ChineseStandard.net --> Buy True-PDF --> Auto-delivered in 0~10 minutes.
