Battery and Charger

Charger Requirements

Charger Requirements
The charger is used for battery charging. During electric wheelchair is charging, do not use it. Charger Technical Data
Input voltage: AC220V (110V) ±10%
Output voltage: 24V/DC Output current: 1.5~5AIngress protection level is IPX1. The charger should meet the requirement of GB 4706.1-2005 and GB 4706.18-2005.

Usage of Charger

Type 1 (charge directly in battery) In order to charge the battery, connect the charger with power supply and battery box’s plug. Do as following instructions to complete charging process:
Step 1: Make sure the charger groove is not blocked.
Step 2: Make sure the electric wheelchair is power off.
Step 3: Unplug the plugs which connect the battery box and controller.
Step 4: Connect the charger’s output plug to the battery box’s power plug.
Step 5: Connect the charger’s main plug to the power supply and the red light will be alight. Fully charging needs 8 to 10 hours, do not overcharge more than 24 hours.
Step 6: As to prevent cut short battery life, please charge the battery at least once per month when the wheelchair is not being used.

Type 2 (charge through controller) In order to charge the battery, connect the charger with power supply and controller socket. Do as following instructions to complete charging process:
Step 1: Make sure the charger groove is not blocked.
Step 2: Make sure the electric wheelchair is power off.
Step 3: Make sure the battery and controller are connected.
Step 4: Connect the charger’s output plug to the socket below the controller.
Step 5: Connect the charger’s main plug to the power supply and the red light will be alight. Fully charging needs 8 to 10 hours, do not overcharge more than 24 hours. Step 6: As to keep the battery life from being shortened, please charge the battery at least once per month when the wheelchair is not being used.

**** Do not stop charging until charge process is finished. Repeat using of battery which is not fully charged will shorten the battery life, so the battery should be fully charged as much as possible. When battery is fully charged, the power indicator will turn to green. Do not stop charging before fully charged. After finish charging, turn off the power supply, otherwise the battery will discharge slowly. Do not charge more than 24 hours. Over-charging is dangerous.

Users should follow the following rules to avoid charging dangers: The electric wheelchair doesn’t include the charger, please use national standard charger that the output voltage is 24V/DC 1.5A~5A. It should be well ventilated when charging. Do not expose the wheelchair to sunlight and humid environment. The charging environment temperature range is from 10℃ to 50℃. If it is out of the environment temperature range, the battery is unable to function well, and can easily make battery damaged.
It’s normal for the fan making a sound during charging. It is for cooling the charger, please do not worry about it. Prevent liquid go into the charger during charging. And do not place charger on the flammable items, such as: fuel, footrest or seat cushion. Please stay away from the flames when charging the battery. The flames may cause battery fire or explosion.

Charging makes hydrogen, do not smoke while charging. Do not unplug the power supply when the socket or your hands are wet, it may cause electric shock. In case of unpredictable accident will happen and hurt the user, do not use or sit on the electric wheelchair when charging.

The Usage and Maintenance of Battery

Wrong operation of replacing battery may cause danger of explosion. Only the same or recommended type of battery is suitable for replacement. And please make sure the battery poles a re correct. Key points for prolong the battery life: charge frequently, to keep battery power full. It’s better to fully charge the battery if the wheelchair is not being used. If stop using for a long time, it’s better to charge twice per month.

Sleep Mode

If the joystick has no operation more than 20 minutes, the power turn off automatically, and the system in the sleep mode, system will be woke up from sleep mode by press power button.

Speed adjustment
According to user’s habits and the circumstances, the wheelchair driving speed is adjustable. Adjust speed by press decrease button or increase button.

Speed is divided into five sections, ranged by 20%, 40%, 60%, 80%, 100% of the max speed.
First gear of speed: 20% of the max speed.
Fifth gear of speed: 100% of the max speed.

Horn Button

Press the horn button, the horn will sounds until you release the button.

Battery Power Gauge

After turn on the power, the battery power gauge is working. The battery power gauge also shows the battery remaining power capacity. As the picture shown, the battery power is full.
When there is only the red or yellow LED light lit, the battery should be charged. And for a long distance driving, the battery should be fully charged. If only the red LED light is lit, the battery power is extremely inadequate, users need to charge battery as soon as possible.

Use of joystick

The wheelchair moving direction is controlled by joystick. The moving extent of joystick also controls the moving speed.

Please turn on or turn off the power when the joystick is in the middle position. Otherwise the controller will let out wrong operation signal. Release the joystick to middle, this mistake will stop. If the mistake is still continuing, perhaps this part is malfunction, do not use it and contact with your dealer for maintenance.

Maintenance

Maintenance of wheelchair includes clean wheelchair, check wheel and battery, and charge battery. For further maintenance please contact with your dealer. Our suggestion is checking the wheelchair every half year, annually overhaul.

Clean and Battery Maintenance

Clean Wheelchair
Please clean the wheelchair regularly. Clean the parts which are frequently touched with user’s body (such as set cushion, armrest, controller) by a clean and slight wet cloth. Do not use organic solvents to clean. If it is a patient user, the wheelchair should be cleaned once per week. If the wheelchair is used by an infectious victim, it should be cleaned and disinfected by disinfectants.
Wheels
Check the tires’ air pressure and their wear condition regularly. When the tire tread pattern depth reduce to 1mm, please replace new tire.
Battery
To make sure that the battery is fully charged frequently. In order to prolong battery life, we strongly recommend users do not to charge until battery run out of power totally.

Wheelchair Malfunction and Checking

When malfunctions happen during the wheelchair is working, please turn off the power before check. Symptom: completely lose power, and all the LED lights on the controller panel are off.

Check Step:
