② Motor Hall is defects, replace or repair the motor
Under voltage protection
Battery voltage is too low, charge the battery.
Locked-rotor protection
Overload or the motor is burnout, to repair or
replace the motor
Accelerator handle
To check whether the accelerator cable box is
damaged, and replace it
The handle bar is not return
when power on.
To check whether it is return of the accelerator cable
box, and repair.
Power supply
system
Charging overheat protection
The battery temperature is higher than 50 ℃, charge
is not available; to normal charge after remove the
battery to indoor and battery temperature is below to
45 ℃.
Protection of Charging
temperature too low
The battery temperature is below 0 ℃, charge is not
available. To normal charge after remove the battery
into indoor and battery temperature is higher than
3 ℃.
Discharge overheat protection
The battery temperature is higher than 65 ℃, it is
not available for discharging , when the battery
temperature is below 60 ℃, it is available for normal
discharging.
Protection of discharge
temperature too low protection.
The battery temperature is below -20 ℃, it is not
available for discharging, when the battery
temperature higher than -10 ℃, it is available for
normal discharging.
Loose connection protection
Re-plug the battery plug, if not normal, repair or
replace
Battery high voltage protection
The total voltage of the battery is too high, the
charging voltage is too high, check the charger, to
repair or replace
MOSFET overheat
①MOSFET temperature is higher than 115 ℃, need
to disconnect the battery plug in order to down the
MOSFET temperature battery to below 80 ℃
② Check whether VCU or anti-theft power supply is
normal, repair or replace
Over voltage protection of
battery cells
The battery's single-cell voltage is too high, check
the battery and charger, repair or replacement
Battery Pack Low Voltage
Protection
The total voltage of the battery is too low, battery
charging or repair and replace it
Low voltage protection of
battery cells
The battery's single-cell voltage is too low, battery
charging or repair and replace it
Charge over current protection
The battery charge current ≥ 26A, Check whether
the charger is burnout, repair or replace.
Discharge over current
protection
The battery discharge current ≥ 75A, Check whether
the controller is burnout, repair or replace
