3 Terms and definitions

The terms and definitions established in GB/T 19596 and the following ones are

applicable to this Standard.

4 Requirements

Hybrid electric vehicles shall meet the safety specifications for automobiles of

relevant national standards, and shall also meet the special requirements

specified in this Standard.

4.1 Requirements for the vehicle structure

4.1.1 Traction battery
4.1.1.1 The requirements for the insulation resistance and creepage distance

of traction batteries shall conform to the requirements of GB/T 18384.1.

4.1.1.6 Types of the traction batteries

The indicated chemical types of the traction batteries shall be clearly visible for

ease of recognition.

4.1.2 Requirements for the electric shock protection
4.1.2.1 AVOID direct contact with the live parts in the power circuit system

No requirements for the non-high voltage power circuit system have been made

in this Standard.

4.1.2.1.6 Vehicle symbols
4.1.2.1.6.1 Each traction battery pack and protective cover of the easily

accessible live part specified in Section 4.1.2.1.1 shall be clearly indicated with

the symbol specified in Figure 1.The symbol shall be clear and solid.

4.1.2.1.6.2 The high-voltage wiring covers shall be orange in color and/or

uniformly composed of orange casings.

4.1.2.2 AVOID indirect contact with the exposed conductive parts in the power

circuit system

4.1.2.3 Insulation resistance

The high-voltage circuit system and electrical chassis of the hybrid electric

vehicles shall be insulating. The requirements for the insulation resistance

values shall conform to the provisions of Section 6.2.2 in GB/T 18384.3-2001.

4.1.2.4 Potential equalization

The potential equalization shall conform to the provisions of Section 6.4 in GB/T

18384.3-2001.
