board circuits’ maximum operating voltage is less than 660V (AC) or 1,000V
(DC) (according to the provisions of GB 156-1993). Other types of hybrid
electric vehicles can use this Standard for reference.

than or equal to 60V (AC) and 25V (DC).
High voltage refers to the voltage whose maximum operating voltage is greater
than or equal to 25V (AC) and 60V (DC). [Translator Note. See Amendment 1]
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 The requirements for the insulation resistance and creepage distance
of traction batteries shall conform to the requirements of GB/T 18384.1. ENSURE that there shall be no hazardous gas accumulation
generated by the on-board traction batteries in any positions of the vehicles.
b) If the on-board energy storages are installed inside the passenger
compartments, any movements of the on-board energy storages shall
ensure the security of the passengers.
c) After the collision and neutralization tests, no electrolyte can enter into the
passenger compartments.
d) After the collision and neutralization tests, the energy storages cannot
explode or catch fire. Third-party protection
During the collision test, the energy storages, such as traction battery packs
and their parts (traction batteries, battery modules and electrolyte) or super
capacitors, etc., cannot be tossed out from the vehicles due to the collision. Short-circuit prevention
During the collision test, PREVENT the power circuits from shorting out. Insulation resistance measurement
After the collision test, MEASURE the insulation resistance according to the
requirements of Section 6.2.2 in GB/T 18384.3-2001 (no preparatory phase is
required). The measurement shall meet the requirements for insulation
resistance. Other requirements
For the hybrid electric vehicles using fuels apart from gasoline or diesel, MEET
the requirements of relevant security standards for corresponding fuels.
4.1.5 Safety specifications for on-board energy storages during
During turnover, the on-board energy storages shall meet the requirements of
Section 4.1.4. Furthermore, the energy storages of the hybrid electric buses
shall meet the requirements of GB/T 17578.
4.1.6 Waterproof requirements
USE an insulation resistance value monitoring system to provide waterproof
supervision. Or COVER the voltage equipment (no requirements for the non-
high voltage parts have been made in this Standard) or USE other methods to
prevent its exposure to water. If vehicles are equipped with insulation resistance
value monitoring system, CONFORM to the requirements of Section 7.3.1 in
GB/T 18384.3-2001. When the vehicles are in parking status and the key switches are in
the “off” position, the vehicles cannot automatically start the engines to charge
the traction batteries. For the vehicles requiring external charging, the hydrogen
measurement during vehicle charging and the corresponding requirements
shall conform to the provisions of GB/T 18384.1.
4.2.3 Manual switch
Each vehicle shall be equipped with a manual switch to switch off the on-board
power supply (such as traction batteries). When the vehicles cannot ensure the
high-voltage system insulation due to maintenance or faults, this switch shall
be able to cut off the high-voltage power circuit system.
4.2.4 Electromagnetic compatibility
The vehicles shall meet the requirements of GB/T 18387, GB 14023, GB 18655
and GB/T 17619.
4.3 Fault protection
This clause specifies the protection against the danger caused by the faults of
the specific systems and parts of the hybrid electric vehicles. The processing
mode of other systems and parts shall be the same with that of the internal
combustion vehicles.
4.3.1 Electrical connection
Any unexpected disconnection of the electric connecting pieces shall not put
the vehicles at risk.
4.3.2 Overcurrent cut-off device
When the current is excessive, USE a circuit protector, cut-off device or fuse to
break the power circuit. This device can be the circuit breaker specified in
5 User manual
In the user manual, PAY special attention to the unique aspects of the hybrid
electric vehicles. For instance, safety regulations for vehicles (i.e.. the orange
line on the vehicle refers to the high-voltage transmission line, the instructions
for various safety symbols on the vehicle, etc.), emergency countermeasures,
correct operations (i.e.. LAY emphasis on lifting the driving wheels during the
vehicle transport and using trailers for transport in the manual. If it is necessary
