Electric scooters are really convenient, and their advantages are far more than just convenience!
Whenever we talk about quality of life, we basically cannot escape the basic framework of “food, clothing, housing and transportation”. It can be said that travel has become the most important life indicator after the three basic survival elements of “food, clothing and sleep”. Careful friends may find that small and portable electric scooters have become the first choice for many people, especially young groups, for short-distance travel.
The popularity of electric scooters is mainly due to the following advantages:
Portability: The size of electric scooters is generally small, and the body is generally made of aluminum alloy, which is light and portable. Compared with electric bicycles, electric scooters can be easily put into the trunk of the car, or carried on the subway, bus, etc. , it can be used in combination with other means of transportation, which is very convenient.
Environmental protection: It can meet the needs of low-carbon travel. Compared with cars, there is no need to worry about urban traffic jams and difficult parking.
High economy: Electric scooters are powered by lithium batteries, which have long batteries and low energy consumption.
High efficiency: Electric scooters generally use permanent magnet synchronous motors or brushless DC motors, which have large motor output, high efficiency, and low noise. Generally, the maximum speed can reach more than 20km/h, which is much faster than shared bicycles.
Seeing this, some people may question that the electric scooter is so small and light, how can its durability and safety be guaranteed? Next, Dr. Ling will give you an analysis from the technical level.
First of all, in terms of durability, lithium batteries of electric scooters have various capacities, and owners can choose 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 cruising range,then Try to choose a battery with a capacity of more than 10Ah.
Secondly, in terms of safety, the body structure of the electric scooter determines its bearing strength and weight. It must have a bearing capacity of at least 100 kilograms to ensure that the scooter is strong enough to withstand the test on bumpy roads. At present, the most commonly used material for electric scooters is aluminum alloy, which is not only relatively light in weight, but also excellent in firmness.
The most important thing to ensure the safety of electric scooters is the motor control system. As the “brain” of the electric scooter, the starting, running, advancing and retreating, speed, and stopping of the electric scooter all rely 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 the efficiency of the motor. At the same time, as a practical vehicle, the motor control system is required to be able to withstand vibration, withstand harsh environments, and have high reliability.
