MAINTENANCE
Read all of SAFETY and this section before attempting any procedure. Pay particular attention to Notices, Cautions, Warnings and Dangers.
short circuit, and needs replacement, so as not to damage rest of the batteries. On the other hand, charging parameters of
the charger should also be checked.
3)
Check battery connection cable once a week. The driving vibration of vehicle may cause the bolt or nut of the
connection cable get loose. It needs to be checked regularly. If loosend bolt or nut is found, fasten it immediately
4)
When starting the electric vehicle, the accelerator pedal shall be slowly pressed to start the vehicle with a small current
until the vehicle runs at a constant speed. If it is started, press the accelerator pedal to the bottom. At this time, the motor
current will increase rapidly, so that the battery will discharge fast and the voltage will drop quickly. The smaller the
discharge depth, the longer the battery life. So reduce the discharge of high current can extend the battery life, and
increase the mileage.
5)
In winter, it is normal for the battery capacity decrease with the decrease of temperature. Take 25°C as the standard,
the capacity is about 85% at 0°C.
6)
The charger should be chosen to match the battery model. When charging, it should avoid high temperature and
humidity. Do not let water flow into the charger to avoid short-circuit accident. The charger should have temperature
compensation function. At 25℃ base point, for every 1℃ increase in ambient temperature, the charging voltage will
reduced by 4mv/cell. When the ambient temperature decreases by 1° C, the charging voltage increases 4mv/cell.
7)
Keep the battery surface clean for a long time, and the vehicle should be parked in a cool, ventilated and dry place.
8)
When the vehicle needs to be placed for long time, the battery must be fully charged first, and the battery should be
fully charged once a month. Or, under the guidance of professional personnel, remove one of the connection cables
from the battery pack, so that the battery is in the open state and can be stored for longer time, and refer to "1. Battery
Storage” for charge the battery
6.2 Routine Maintenance Items
Item Period Content Standard Maintenance
Battery
single cell
voltage
One
month
When the battery
group is fully
charged, use
multimeter measure
voltage of a single
cell
Single voltage
difference, 6V
battery should be
less than 0.2V, 8V
battery should be
less than 0.3V, 12V
battery should be
less than 0.4V
Remove the backward
single cell and charge it
separately for
maintenance. If the
voltage still deviates from
the standard, replace the
cell with low voltage
Battery
appearance
One
month
Visually check
battery case and
cover for acid
leakage,
deformation, cracks
or damage
Appearance is
normal
If the appearance is
abnormal, first confirm
the cause. If it affects
normal use, replace the
battery.
Visually check the
battery surface for
dust and stains
Appearance is
clean
Clean the dust and stains
on battery surface with a
dry cloth
Visually check
whether there is rust
or corrosion in the
connector or
terminal
No rust, no
corrosion
Slight rust or corrosion,
use a steel brush to
remove rust, and apply
rust inhibitor. For severe
rust or corrosion, replace
with a new connector or
battery
