HV safety
The pure electric powertrain, HV parts and
cables of this vehicle are equipped with
electromagnetic shielding devices. The
amount of electromagnetic wave emitted
by the electromagnetic shielding devices is
almost the same as that of conventional
gasoline-powered vehicles or household
appliances. The electromagnetic wave will
not cause damage to human body.
The electric energy is used as the
power source of this vehicle, and the
power battery provides HV DC for
the HV electrical system. The power
battery is converted into three-phase
AC by the motor controller to supply
power to the drive motor. In order to
ensure the personal safety of
passengers and first-aid personnel,
please pay attention to the following
matters:
• There is a HV fuse in the power
battery to provide short-circuit
protection for the power battery.
• The positive and negative HV
cables connected to the power
battery are usually controlled by
the LV normally open relay. When
the vehicle LV power supply is
disconnected, the relay can be
disconnected to prevent HV
current from flowing out of the
power battery.
• Orange HV warning labels are
affixed to some parts of the
vehicle to warn that there is HV in
this part. Always observe the
contents of the HV system
warning label.
• The voltage can only be reduced
to safe voltage for human touch
15 minutes after the vehicle
power supply is cut off. To
prevent serious injury or even
death due to severe burns or
electric shock, do not touch, cut
off or damage any orange HV
cables or HV components.
• Non-professional service
personnel are not allowed to
touch, disassemble or install any
parts of the HV system at will,
such as drive motor, motor
controller, A/C compressor and
power battery.
• When the vehicle is running, its
control system will always monitor
whether there is HV leakage. If a
malfunction is detected, the MIL
on the instrument cluster will
illuminate.
