The Composition and Technology of Electric Scooter

1. The composition of electric scooters

The electric scooter has more than 20 parts and components. Of course, these are not all. There is also a motor control system motherboard inside the car body.

The motors of electric scooters generally use hundreds of watts of brushless DC motors or permanent magnet synchronous motors with special controllers. The brake control generally uses cast iron or composite steel; lithium batteries have a variety of capacities, which can be chosen according to their actual needs. If there is a certain requirement for speed, try to choose a battery above 48V; if there is a requirement for mileage, try to choose a battery with a capacity above 10Ah.

The body structure of an electric scooter determines its bearing strength and weight. As one of the most popular micro-mobility devices, an electric scooter must have a bearing capacity of at least 100 kg to ensure that the scooter is strong enough to withstand the test on bumpy roads. At present, the most commonly used electric scooters are aluminum alloy materials, which are not only relatively light in weight, but also very strong in terms of robustness.

The dashboard can display information such as the current vehicle speed and mileage. Generally, a capacitive touch screen is selected. Generally, there are two types of tires: tubeless tires and air tires. Tubeless tires are relatively expensive; for the design of lightweight foldable scooters, the frame is generally made of aluminum alloy.

2. The core of electric scooter technology

If the components of the electric scooter are separated and evaluated one by one, the cost of the motor and control system is the highest. At the same time, they are also the "brain" of the electric scooter. The start, run, advance and retreat, speed, and stop of the electric scooter depend on the motor control system in the scooter.

Electric scooters can run quickly and safely, and have high requirements on the performance of the motor control system, and also have greater requirements on the efficiency of the motor. At the same time, as a practical vehicle, the motor control system is required to withstand vibration, endure harsh environments, and have high reliability.
