CAUTION
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 7 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 3 months, the power
battery must be fully charged
and then discharged to 40%-60%
every 3 months. Otherwise, over-
discharge may result, leading to
battery performance degradation
or even damage. Any vehicle fault
or damage so caused will not be
covered by the quality warranty.
As the power 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 authorized dealer or
service provider immediately for
maintenance.
No one is allowed to enter the
vehicle when the battery pack
needs to be repaired.
Power Battery Recycling
How to scrap an NEV:
1. Take the vehicle to the BYD recycling
service provider that will assess the
residual value of the power battery.
2. Take the assessed vehicle to the
recycling organization to disassemble
the power battery.
3. Tale 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 power
batteries to the recycling service
outlet. Those who hand over
waste power batteries to other
organizations or individuals
for dismantling or disassembly
without authorization, thus
causing environmental pollution
or accidents, shall bear the
corresponding responsibilities.
Low-voltage Battery
The low-voltage (12V battery) is located
under the rear left seat.
Battery working modes include
"Normal", "Sleep", "Ultra-low Power",
"Low-Voltage Protection", etc. 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.
To avoid low-voltage battery feed,
the smart 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 smart 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-
