Terms and definitions determined by GB/T 19596 and the following ones are applicable to this document. 3.1 rechargeable electrical energy storage system; REESS A rechargeable energy storage system that can provide electrical energy. 3.2 high voltage service disconnect A device, equipped with a built-in voltage class B part, that is used to disconnect high- voltage circuits when inspecting or repairing voltage class B components. 3.3 low voltage service disconnect A device, not equipped with a built-in voltage class B part, that is used to disconnect high-voltage circuits when inspecting or repairing voltage class B components. 3.4 conductive connection Electrical connection made using conductors. 3.5 high voltage connector A component consisting of one or more sets of conductor terminals and insulating sheaths that provides electrical connection and disconnection functions between high- voltage cables in electric vehicles and between high-voltage cables and high-voltage components. [Source. GB/T 37133-2025, 3.2] 3.6 direct driving The driver controls the vehicle through the steering wheel, brake pedal, gear shifting mechanism, accelerator pedal, etc. 3.7 cut off the power of propulsion system The high-voltage circuit of the entire vehicle is disconnected, at least the high-voltage circuit between the drive system and the rechargeable electrical energy storage system is disconnected. For fuel cell vehicles, the circuit between the fuel cell system and the drive system must be disconnected simultaneously. 3.8 touch current The electric current flowing through a person or animal's body when the person or animal comes into contact with one or more accessible parts of a device or apparatus. [Source. GB/T 12113-2023, 3.1]4 Voltage level
4.1 Electrical components or circuits are classified according to their maximum working voltage as shown in Table 1. 4.2 For voltage class A electric circuits and voltage class B electric circuits that are conductively connected, if one pole of a DC live part in the circuit is connected to the electrical chassis, and the maximum voltage between any other live part and this pole is not greater than 30 V (a.c.)(rms) and not greater than 60 V (d.c.), then the conductive connection circuit does not completely belong to the voltage class B electric circuit, and only the part that operates at voltage class B electric circuit is identified as a voltage class B electric circuit.5 Safety requirements
5.1 Requirements for personnel protection against electric shock 5.1.1 General 5.1.1.1 Requirements for personnel protection against electric shock shall include the following four parts. -- High voltage marking requirements; -- Direct contact protection requirements; -- Indirect contact protection requirements; -- Waterproof requirements. 5.1.1.2 For voltage class A electric circuits and voltage class B electric circuits that are conductively connected, if one pole of a DC live part in the circuit is connected to the electrical chassis, and the maximum voltage between any other live part and this pole is not greater than 30 V (a.c.) (rms) and not greater than 60 V (d.c.), then the requirements of 5.1.4.1, 5.1.4.2, 5.1.4.3 and 5.1.5 do not apply to the circuit (including the DC and AC parts). 5.1.2 Requirements for high-voltage marking 5.1.2.1 Requirements for high-voltage warning sign Voltage class B energy storage systems or generating devices (such as REESS and fuel cell stacks), voltage class B electric circuit systems and components (such as drive motors, high-voltage distribution boxes, on-board chargers, etc.) shall be marked with the symbols shown in Figure 1.For voltage class A electric circuits and voltage class B electric circuits that are conductively connected, if one pole of a DC live part in the circuit is connected to the electrical chassis, and the maximum voltage between any other live part and this pole is not greater than 30 V (a.c.) (rms) and not greater than 60 V (d.c.), then REESS allows the symbol shown in Figure 1 not to be marked. The symbol background shall be yellow, and the border and arrow shall be black. When the barrier or enclosure is removed to expose the voltage class B live parts, the same symbol shall be clearly visible on the barrier and enclosure. When assessing whether this symbol is needed, the accessibility and removability of the barrier or enclosure must be considered. 5.1.2.2 Marking requirements for voltage class B wires In voltage class B electric circuits, the outer sheath of cables and wire harnesses shall be distinguished by orange, except for those behind barriers or inside enclosures that meet the requirements of 5.1.3.2. 5.1.3 Requirements for direct contact protection 5.1.3.1 General requirements Direct contact protection is achieved by physically isolating the human body from voltage class B live parts through insulating materials, enclosures, or barriers. The enclosure or barrier can be a conductor or an insulator. The direct contact protection requirements for specific components shall meet 5.1.3.2 ~ 5.1.3.5. For category M2 and category M3 vehicle types, if a rooftop charging device is installed on the roof, as shown in Figure 2, and if the shortest path from the bottom step of the vehicle entrance to the exposed voltage class B live part of the rooftop charging device is at least 3 m, then the exposed voltage class B live part of the rooftop charging device can be exempted from the direct contact protection requirement. ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
