5.4.6.1 It shall maintain the uniformity of the internal temperature field of the
traction battery system. When the traction battery system is tested in
accordance with 8.5.4, the temperature difference of the internal temperature
field in the traction battery pack shall not exceed 5 °C.
5.4.6.2 If the traction battery system consists of multiple traction battery packs,
during the layout of the traction battery packs in the vehicle, it shall consider
the consistency of the ambient temperature, AND it is preferable for the
temperature difference between different traction battery packs to be within the
range of 8 °C.
5.5 Safety requirements

The electrical insulation performance of the traction battery system shall
comply with the calculation requirements of 6.1 in GB/T 18384.1-2001 AND the
performance requirements of 6.2 in GB/T 18384.3-2001.
5.5.3 High voltage power-off protection.
The traction battery system having a voltage higher than 60 V shall have an
automatic power-off device, AND it is preferable to have a manual power-off
device.
5.5.4 Overcurrent protection.
When the output current of the traction battery system rises up to the set
overcurrent value, it shall limit the discharge power of the battery system OR
otherwise require the vehicle control ECU to perform power limit, AND
meanwhile it is preferable for the battery system to be able to output alarm
signal.
5.5.5 Overtemperature protection.
When the traction battery system temperature reaches up to the
overtemperature protection value, it shall limit the discharge power of the
battery system OR otherwise require the vehicle control ECU to perform power
limit, AND meanwhile it is preferable for the battery system to be able to output
alarm signal.
