Battery
Battery Pack
Battery pack in the vehicle provides energy require for the vehicle.
To maintain optimize battery pack performance, it is best to completely charged the battery regularly. A good practise is to
charge battery pack daily or after each use.
Attention: Each battery pack has factory serial number. This information must be provided when replacing the battery pack
by authorized dealer.
Battery pack characteristics
A new battery pack will reach optimum performance after 20-30 charge and discharge cycles.
New battery pack must be completely charged before use.
Charge the battery pack each day or after each use
To maintain good battery performance, avoid letting battery pack to discharge to less than 20% SOC
On-board battery charger
On-board battery charger is located on the vehicle side panel.
Information of the battery pack(s) state of charge are display on the dashboard.
The vehicle should be charged at least once every 10 days even if it is not used.
Important note: Avoid parks the vehicle at places with extreme temperature.
Charging of battery pack
Warning! Must always use factory recommended charging cable (as well as length).
Use of non-recommended or extended cable may cause fire and damage the charger, which might result in serious harm or
fatal accident.
Warning! When using electrical plug that are not conform to factory charging requirements, care must be taken to ensure the
charging cable has at least of 20A of current rating.
Warning! Charging the batteries at places without good air ventilation may result in fire. Do not smoke in the charging area.
Park vehicle on a flat surface. Ensure charging area has good air ventilation.
Ensure ignition key is at OFF position
Inspect the charging cable has no crack, loose or worn out. Do not use a worn-out charging cable.

First plug in the charging cable to the charging socket (located at the right side of vehicle panel), then plug in the
charging cable to wall outlet or charging station.
Use only 220 volts, alternating current (A/C), 16 A socket as shown in (2)
Connect the charging gun as shown in (1) to the vehicle socket as shown in (3)
Charging cable should be directly connect to wall charging point, do not share with other appliances to ensure it
is not overload
When disconnecting the charger, first unplug the charging cable from wall socket or charging station, then
disconnect charging cable from the vehicle.

Note: to be replaced by charging gung
Start charging
Select a charging place that can charge for long hours, ensure connection are safe.
Switch ignition key to OFF or Pop up the one-key start button, and gear selector to N.
One end of charger connects to the socket of the vehicle, and another end to home socket (110-230 V,16 A) or standard charge
station.
Charging status will be displayed with % of SOC information.
Charging time
Charging time depends on
- Balance SOC in the batteries pack
- Electrical source voltage and current
It takes an approximately 6-12 hours to complete charging from low SOC.
Finished charging
Remove connector from the 110-230V socket first, then from the vehicle. Safe keep the charging gun.
First time charging or after vehicle not been used for a long time
If the battery pack is at low SOC, the temperature of battery may become low because internal regulator does not function.
Note: When a vehicle has not been used for a long time, it is better to pre-heat the battery pack (for 10hours) before use.
Charging in this situation may be extended to 24 hours.
During driving, battery indicator will indicate percentage of batteries SOC as shown in (1)
As shown, when the indicator turns orange, must charge batteries as soon as possible.
Waring! Immediately charging of charging is necessary when the indicator turns red
Waring! Allow the batteries SOC to red zone will reduce the life of batteries, owner may lose warranty
Warning! Must always keep note of the following to prevent serious damage to your vehicle.
Precautionary notes about batteries

Warning! During batteries charging, do not carry out any electrical works on the vehicle or in the vicinity area.
Warning! Disconnect the main supply before attempt to perform service and maintenance of battery pack, subsequently
disconnect all other electric accessories (if any), then disconnect the negative terminal of the 12 V battery, finally disconnect
the negative terminal of the battery pack. These steps will discount battery supply to the motor, the vehicle will not able to
operate. However, completing the above steps do not eliminate high voltage (in the battery pack), therefore, no one should
touch the terminals of the battery box.
Ensure all 12 V accessories connect directly to negative terminal. Do not connect to the virtual ground of chassis or
vehicle body.
Do not connect any accessories to 12V battery directly. Connect the accessories to 12 V junction box
Do not connect jump start cable to any batteries of the vehicle
Always wear safety glasses when servicing and doing maintenance works. Always wear protection mask and glove when
working on connecting electrical components or batteries.
Use only insulated tools whenever working on the batteries bank
Always maintain cleanliness and ensure no corrosion on batteries terminals.
A 12 V socket is provided in the cabin, this is a “cigarette lighter” socket, it has a maximum power rating of 120w (10A).
Only accessories lower than this rating can be used. This socket will only supply power when the vehicle is operating.
Motor and controller
The drive come from permanent synchronous motor. The energy of is provided by the lithium battery pack.
Motor
The motor is in the middle of chassis, it is connector to the controller, which regulate the output power delivers to the motor.
Both the controller and the motor are air cool. It is not required any maintenance by the user.

5. Comfort
Door lock functions
The vehicle is equipped with an electric lock, it is controllable through the locking system located on the left side door
Lock door: Turn the key clockwise
Open door: Turn the key anticlockwise
The door will be automatically locked when the vehicle speed reaches 20 km/hr.
Warning! The door structure does not provide adequate protection during accident. Therefore, driver and passenger must
always wear safety belt during operation to minimize potential injuries.
Rear mirror
There are two rear mirrors in the vehicle.
Adjustment of rear mirror is done manually.
Rear mirror can be folded during parking.
Side window
