5.2 The operation and maintenance of charger
Note:
As standard configuration, the charger is built into the vehicle; in some cases, it may not be built into
the vehicle. If it’s built into the vehicle, the position of the charger is either under the seats or behind the
front body.
The procedure to use the charger (when the charger is built in the vehicle).
1. Connect the cord to the receptacle on the vehicle;
2. Connect the cord to the receptacle to the outlet of household grid.
3. After the charger cord is connected, the red indicator on the charger will flash, charger starts the
procedure of self-inspection, after self-inspection, green indicator flashes, and charger starts to charge
the batteries.
4. When battery capacity is less than 80%, the green indicator flashes slowly. When battery capacity is
more than 80%, the green indicator flashes fast. When the battery is fully charged, the green indicator
will stop flashing and always be on and the charger will stop charging automatically.
Note:
This charger has the function of over-discharging protection to protect the battery from
over-discharging. When battery is close to the charging point, it will reduce the discharging current from the
battery to reduce the speed of the vehicle, if it fails to charge the battery, it will cut the current from the
battery and stop the vehicle to force user to charge the battery.
Note:
When the grid voltage is out of range of 90-260V, the charger will stop charging to protect itself, at
the same time, the failure code light will be on to remind users. When the voltage returns back to the
requested voltage range of 90-260V, it will automatically start to charge.
Caution!
Do not use charger if there is water in it.
Caution!
Use the charger when the environment temperature is between -10
℃
to +45
℃
WARNING!
Only qualified electrician is allowed to open the housing of the charger.
WARNING!
When charging the batteries, hydrogen will be generated, so it’s important to keep the charging area in safe
and dry room with good ventilation; and also to avoid fire and spark.
5.3 Maintenance of the Traction DC Motor
WARNING!
Check to make sure there is no explosive gas vapor in the air, otherwise, it may cause
severe injury and damage to your body and property if the explosive gas vapor contacts the sparks
generated from the motor.
1)
For DC motor, the carbon brush should be checked every 3 months to see if it is worn or not as it is an
easily worn part. If it is not replaced in time before it wears out, it will badly damage the motor.
2)
Do not keep the motor running idle for long periods of time. Any idle running of the motor should be
avoided.
3)
Removal of mud, sand and other clinging objects should be done frequently to keep unit from
overheating.
4)
Periodically use low pressure air to remove the dust from the carbon brush and the commutator.
Periodically check the connection of the carbon brush and the commutator.
Main malfunction symptoms and possible causes of DC motor
Item Symptoms
Possible Causes
1
All copper plates turn black.
The pressure of the brush is incorrect.
2
The commutating copper
turns black in a certain order
and in groups.
Short circuit happens between the commutating copper or among
the armature coil; poor welding or disconnection happens between
the commutating copper and the armature coil.
3
The commutating copper
turns black disorderly.
The central line of the commutator deviates or its surface is not
round and not smooth.
