Common faults of electric wheelchairs

Common faults of electric wheelchairs and their possible causes and solutions are as follows:

Cannot start:

Possible causes: low battery; switch not turned on; controller failure;

Solution: Check the battery and charge it to full power; make sure the power switch is turned on; if the problem persists, check the controller or contact professional repair.

Abnormal speed:

Possible causes: battery performance degradation; motor failure; controller setting problem.

Solution: Check the battery power and connection, and replace the battery if necessary; check the motor and its connection wires to ensure that there is no damage; adjust the controller settings to ensure normal operating mode.

Directional control failure:

Possible causes: operating lever failure; sensor problem.

Solution: Check whether the operating lever is normal, clean or replace necessary parts; check the sensor connection and repair if necessary.

Short battery life:

Possible causes: battery aging; low ambient temperature; long-term non-charging.

Solution: If the battery is aging, consider replacing it with a new one; use it at a suitable temperature and avoid extreme temperatures; charge it regularly to keep the battery in good condition.

Charging failure:

Possible causes: charger failure; battery connection problem.

Solution: Check whether the charger is working properly, try using another charger; make sure the battery cable is intact and in good contact.

Wheel stuck:

Possible reasons: Object stuck in the wheel; Wheel wear.

Solution: Check and remove obstacles around the wheel; Check whether the wheel is severely worn and replace if necessary.

Make abnormal noise:

Possible reasons: Motor failure; Mechanical parts wear.

Solution: Check the motor and connectors, lubricate or replace parts if necessary;

Regular inspection and maintenance of electric wheelchairs can effectively reduce the occurrence of failures and improve safety and comfort.
