Low-Voltage Battery - BYD SEAL 2023 Owner's Manual

WARNING
If the vehicle catches fire,
●
use dedicated fire extinguishers
instead of water-based fire
extinguishers.
CAUTION
To ensure safety of the high-
●
voltage battery, stop the vehicle
away from flammable and
explosive materials, ignition
sources and various hazardous
chemicals.
The available battery capacity
●
decreases as the vehicle is used
over time.
Prolonged exposure to heat
●
sources and direct sunlight
will reduce high-voltage battery
service life.
When the vehicle is not to
●
be operated for an extended
period (over seven days), it is
recommended that the battery
SOC should be kept at 40%-60%
to prolong its service life. When
the vehicle is not to be operated
for over three months, the high-
voltage battery must be fully
charged and then discharged to
40%-60% every three months.
Otherwise, over-discharge may
lead to battery performance
degradation or even damage. Any
vehicle fault or damage so caused
will not be warranted.
As the high-voltage battery is
●
arranged at the bottom of
the vehicle, careful driving is
recommended in case of bumpy
roads. If there is a collision
with the high-voltage battery,
contact a BYD authorised dealer
or service provider immediately
for maintenance.
CAUTION
No one is allowed to enter the
●
vehicle when the battery pack
needs to be repaired.
Recycling the High-Voltage Battery
How to scrap an NEV:
1. Take the vehicle to the BYD recycling
service provider that will assess the
residual value of the high-voltage
battery.
2. Take the assessed vehicle to the
recycling organisation to disassemble
the high-voltage battery.
3. Take the battery to the recycling
service provider which will buy back
the battery.
WARNING
New energy car owners have
●
the responsibility and obligation
to hand over waste high-voltage
batteries to the recycling service
outlet. Anyone who hands over a
used high-voltage battery to any
other organisation or individual,
or removes/disassembles a
high-voltage battery without
authorisation, shall be liable for
any environmental pollution or
safety incident so caused.

Low-Voltage Battery

The low-voltage battery is located under
the rear left seat.
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
