The electric wheelchair is the first choice of means of transportation for the elderly and disabled. Some customers often have some failures when they buy a poor-quality electric wheelchair, which makes them unable to walk. This is also the most common electric wheelchair failure problem encountered by users. Today, I will analyze for you the reasons why the electric wheelchair does not run when it is powered on and what the price of the electric wheelchair depends on.

What is an electric wheelchair?
An electric wheelchair is a wheelchair to which an electric motor and means of navigation control have been added. Usually, a small joystick is mounted on the armrests rather than manual power to move the wheelchair. Therefore, the fundamental difference between the electric wheelchair and the traditional electric scooter, battery car, bicycle, and other means of transportation is that the electric wheelchair has an intelligent control controller. According to the different control methods, there are rocker controllers, and controllers controlled by various switches such as head or blowing systems. The latter is mainly suitable for severely disabled people with upper and lower limb disabilities. Today, the electric wheelchair has become an indispensable means of transportation for the elderly and the disabled. The electric wheelchair is suitable for a wide range of objects. As long as the user has clear consciousness and normal cognitive ability, using an electric wheelchair is a good choice, but it requires a certain amount of room for movement.
What problems usually cause the electric wheelchair to fail to run?
1. Insufficient battery voltage: Insufficient battery voltage is usually seen in electric wheelchairs that have been used for a long time. Due to the end of the service life of the battery, serious vulcanization, or a breakage, serious lack of liquid, resulting in insufficient storage capacity. When the battery voltage is too low, turn on the power switch, and the power indicator light is on, but the motor cannot be driven forward.
2. The clutch is in the open state: the electric wheelchair with an electromagnetic brake can only be driven electrically when the electromagnetic brake is in the closed state. The clutch is in the open state and cannot be driven electrically, and can only be pushed manually.
3. Electric wheelchair controller fault: The main board of the electric wheelchair controller is damaged or the control lever drifts, and 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 out or burned out: some electric wheelchairs use brushed motors, and the carbon brushes of brushed motors are vulnerable parts that need to be replaced regularly.
The price of an electric wheelchair depends on the configuration of the car.
Many elderly people or customers who buy electric wheelchairs for the first time think that electric wheelchairs are more expensive. This is because they don't understand the configuration of the electric wheelchair, and blindly compare the electric wheelchair with the electric car. The price of an electric wheelchair depends on the configuration of the car. The configuration of the electric wheelchair has the following aspects:
1. Controller: Most of the wheelchair controllers on the market now use British PG, New Zealand DYNAMIC, etc. The control performance of different brands of controllers is quite different. The price difference between different brands of controllers may be around one to two thousand yuan.
2. Batteries: Batteries are divided into lead-acid batteries and lithium batteries. Lithium batteries are lighter, and the price of lithium batteries is much more expensive than lead-acid batteries. The price of the battery varies greatly depending on the capacity. For example, batteries with 12AH, 20AH, 36AH, or even larger capacities are more expensive.
3. Motor drive system: Although the domestic motor technology is relatively mature, the quality difference between different motors is still very large. Inferior motors are noisy and generate high heat when used, which affects the cruising range.
4. Reduction gear: In the long-term electric wheelchair maintenance process, it is found that there are many problems with the electric wheelchair reduction gearbox. The common problems are poor oil seal quality, resulting in oil leakage, severe gear wear, resulting in loud noise, and poor handling.
From the comparison of the above core components, it is not difficult to find that the common characteristics of a good electric wheelchair are durable leather, low repair rate, and comfortable operation and driving. However, poor-quality electric wheelchairs have their discomforts. Don’t underestimate the simple electric wheelchair. Poor-quality electric wheelchairs will cause unexpected problems and failures. You get what you pay for, and it is recommended to start with quality, configuration, and user-friendly design when buying an electric wheelchair.
