BYD TANG 2024 - Low-Voltage Battery

WARNING
to hand over waste high-voltage
batteries to the recycling service
outlet. Anyone who hands over a
used high-voltage battery to any
other organization or individual,
or removes/disassembles a
high-voltage battery without
authorization, shall be liable for
any environmental pollution or
safety incident so caused.
Low-Voltage Battery
●
●
To prevent the SOC of the low-
voltage battery becoming too low, the
intelligent charging function will be
actively triggered if conditions (hood
closed, ignition "OFF", high-voltage
battery discharging allowed, and low-
voltage battery level lower than the
design value) are met.
●
When the intelligent charging function
is triggered, the low-voltage battery
is charged through the high-voltage
battery. Therefore, it is normal that the
SOC or the pure-electric driving range
displayed on the cluster decreases,
when the vehicle is started after being
idle.
●
If smart charging fails, the low-voltage
battery may cut o󽗈 the vehicle's power
supply. If you 󽗉nd before use that
the vehicle is not powered, try to
activate the low-voltage battery by
pressing the driver's door microswitch
continuously, and immediately power
on the vehicle to charge the low-
voltage battery. It is recommended to
charge it for more than one hour.
REMINDER
●
The low-voltage battery contains
relays. Thus, it is normal that relay
operating sounds may be emitted
from the battery.
●
The low-voltage battery shall
be charged with professional
charging tools, and shall not be
removed for recharging without
permission.
●
Do not jump-start the vehicle with
another fuel vehicle, as this may
damage the low-voltage battery.
●
The low-voltage battery is a
battery on low-voltage platform
that is di󽗈erent from an ordinary
lead-acid battery. Please read the
instructions for use in this manual
in detail.
●
The low-voltage battery has a
built-in power manager. Do not
disassemble or repair the battery
without permission to avoid
damaging the battery or causing
personal injury.
●
The low-voltage battery needs to
communicate with the vehicle for
normal use, so it is important to
connect its connector and wiring
harness correctly.
Waking up the Vehicle from Low SOC
Wake-up by the driver's door
microswitch
●
The low-voltage battery features the
dormant/wakeup function. After long-
term parking, if locating or unlocking
the vehicle cannot be performed with
the smart key, it indicates that the
low-voltage battery may have entered

USING AND DRIVING
Battery working modes include
"Normal", "Sleep", "Ultra-low Power",
"Low-Voltage Protection". The purpose
is to protect the battery cell from
damage. If the vehicle system is in
good condition, the vehicle switches
between these modes automatically,
having no e󽗈ect on your use of the
vehicle.
