Because of the development of science and technology, people’s life expectancy is getting longer and longer, and there are more and more elderly people all over the world. The emergence of electric wheelchairs and electric scooters largely indicates that this problem may be solved. Although electric wheelchairs and electric scooters They are slowly gaining popularity, but they are still poorly understood by the general public.

Based on this, in the next few issues, we will take the electric wheelchair as an example to disassemble the key components of the electric wheelchair and explain in detail, so that everyone can know what to do when purchasing electric wheelchairs and scooters.

In the first issue, let’s talk about the core of the electric wheelchair, the controller.

Generally speaking, electric wheelchair controllers have the following functions:

(1) Motor direction speed control

(2) Alarm buzzer control

(3) Motor solenoid valve control

(4) Battery power display and charging indication

(5) Fault detection alarm

(6) USB charging

The physical working principle of the controller is very complex, and as a consumer, you do not need to know too much.

In simple terms, the controller consists of two modules, the operation controller and the motor controller. The controller has a built-in microcontroller, which controls the working logic through programming and controls the speed of the motor to ensure the wheelchair can be controlled freely on different roads.

Electric wheelchair controllers have international brands and domestic brands. For families with similar economic levels, in order to use more convenient and safe, the controllers of international brands will be better.

1.A newly established wholly-owned subsidiary of Dynamic Controls in Suzhou, China, mainly produces electric wheelchairs and controllers for elderly scooters. It is currently the world’s largest supplier in the industry. The R&D base is located in New Zealand and the production plant is located in the domestic bonded area. (All have passed the medical ISO13485 certification), with branches and sales centers in the United States, the United Kingdom, Taiwan and Australia and other countries and regions, the controller can adjust the straight running and turning speed of the motor through a computer or a special programmer.

2.PG Drives Technology is a manufacturer of wheelchair and scooter controllers. In addition, PG DrivesTechnology is now a well-known supplier of industrial electric vehicle controllers with a large scale, and its products are widely used in: floor cleaning machines, material handling vehicles, golf carts, electric wheelchairs, and electric scooters.

PG Drives Technology has a modern design and manufacturing base in the UK, a fully functioning sales and service organization in the US, and sales and technical support offices in Taiwan and Hong Kong. There is also an authorized service organization in Australia, and sales and service partners are located in many other countries around the world. The controller can adjust the motor straight and turning speed through a computer or a special programmer.

Dynamic and PG are currently the two most used imported controllers in the industry. The use effect has been tested by the market and customers, and the technology is quite mature.

Everyone tries to choose international brands when purchasing electric wheelchairs and scooters. At present, domestic controllers are relatively poor in terms of operability and safety.
