Electric wheelchairs are the first choice as a means of transportation for people with disabilities. Some customers buy electric wheelchairs with poor quality and often have some failures, resulting in inability to walk. Today, I will analyze for you what happens when the electric wheelchair has electricity and can't walk. This is also the most common problem of electric wheelchair failures encountered by users. Electric wheelchairs are usually caused by the following problems:
1. Insufficient battery voltage: It is usually seen in electric wheelchairs that have been used for a long time. Because the battery life has expired, the vulcanization is serious, or there is a broken situation, the liquid shortage is serious, and the power storage is insufficient. When the battery voltage is too low, turn on the power switch and the power indicator lights up, but it cannot drive the motor forward.

2. The clutch is in the open state: The electric wheelchair with the electromagnetic brake can only be driven electrically when the electromagnetic brake is in the closed state. When the clutch is open, the electric wheelchair cannot be driven electrically, and can only be pushed manually.
3. Failure of the electric wheelchair controller: If the main board of the electric wheelchair controller is damaged or the control rod drifts, there may be a situation where there is electricity but cannot walk. In this case, it is recommended to replace the matching controller.
4. Motor carbon brushes are worn or burned out: Some electric wheelchairs use brushed motors. The brushed motor carbon brushes are vulnerable parts and need to be replaced regularly. If they are not replaced for a long time, the wear and tear will cause the electrical appliance to fail to start.
Compared with traditional manual wheelchairs, electric wheelchairs are more convenient. Ordinary manual wheelchairs require manpower to drive or even need to be accompanied by others. Of course, the manual wheelchair can be folded and put in the trunk of the car, which is suitable for people with general situations or short-term mobility problems, and is not suitable for long-term sitting. The electric wheelchair is battery-generated, which can save a lot of physical strength of the elderly. At present, most of the electric wheelchairs on the market are composed of aluminum alloy materials, controllers, brand motors, etc., and safety is also the first in the design concept. It has the characteristics of anti-rollover, strong load capacity and comfort.
