The electric bicycle is a mechatronic personal transportation system that uses a battery as an auxiliary energy source on the basis of an ordinary bicycle, and is equipped with a motor, a controller, a battery, a handlebar gate and other manipulation parts and a display instrumentation system.
The history of the development of electric bicycle in China is generally recognized by the industry as three stages: the primary stage of electric bicycle, the initial production scale stage, and the super-speed development stage.
The primary stage of the electric bicycle is also known as the early experimental production stage of the electric bicycle, which is from 1995 to 1999. This stage was mainly about researching the key technologies of the four major components of electric bicycles, namely motor, battery, charger and controller. In terms of R&D and production, the main focus was on the spontaneous collection of information, tracking technology, organizing market observation, and placing small batches on trial in the market, which led to the electric bicycle coming into the consumers' view and being gradually recognized and accepted by them. From a technical point of view, early electric bicycles could only travel about 30 km on a single charge, with short battery life, poor climbing ability and easy wear and tear, and the motors were all brushless motors. But it was the accumulation of this period that laid the foundation for the scale of this industrialization today in terms of talent, technology and product development.
The second stage is called the first production scale stage, because there are several opportunities to advance the electric bicycle in this time period, making the electric bicycle in the primary stage of struggling to usher in the spring, but also the development of the industry into the scale, and the most valuable of these opportunities are the "motorcycle ban" in various cities "and the SARS outbreak in 2003.
The main components of electric bicycle
Charger
The charger is a device that replenishes the battery with electrical energy, and is generally divided into two modes: two-stage charging mode and three-stage charging mode. Two-stage charging mode: first constant voltage charging, charging current gradually decreases as the battery voltage rises, and after the battery power replenishes to a certain level, the battery voltage will rise to the charger's set value, then it converts to trickle charging. Three-stage charging mode: When charging starts, the
The controller is the component that controls the motor speed and is the core of the electric vehicle electrical system, with under-voltage, current-limiting or over-current protection functions. The intelligent controller also has a variety of riding modes and self-test function for the whole electric parts of the vehicle. The controller is the core component of the electric bicycle energy management and various control signal processing.
Electric bicycle purchase common sense
1. Choose the brand. Pay attention to choose the brand with high reputation, quality and after-sales service are guaranteed.
2. Pick a model. Different models, their safety and performance vary greatly. It is recommended to buy simple and light type.
3. Look at the appearance. Pay attention to the surface finish, gloss, pay attention to the quality of welding, painting, plating.
4. Find the feeling. Test ride, feel the vehicle start, acceleration, driving is smooth, the vehicle is comfortable to operate, check the brake tightness, handlebar flexibility, wheel mobility.
