With the development of science and technology and the acceleration of people’s pace of life, electric vehicles have gradually become people’s first choice for travel. Among the many electric vehicles, electric scooters are favored by more and more adults because of their convenience, environmental protection, economy and other advantages. This chapter will introduce the relevant knowledge of electric scooters in detail, including the types, structure, performance, purchase, use and maintenance of electric scooters.
1. Types of electric scooters
Electric scooters are mainly divided into two categories according to different driving methods: hub motor driven and central axis motor driven.
1. Hub motor-driven electric scooter: The motor of this model is installed in the wheel, and drives the wheel to rotate through a chain or belt, thereby realizing the advancement of the vehicle. Hub motor-driven electric scooters have the advantages of compact structure, light weight, and high efficiency, and are currently the most common type of electric scooters on the market.
2. Central axis motor-driven electric scooter: The motor of this type of vehicle is installed on the central axis of the vehicle, and drives the wheels to rotate through a chain or belt to move the vehicle forward. Electric scooters driven by central axis motors have high torque output and are suitable for complex road conditions such as climbing hills, but their structures are relatively complex and they are heavy.
2. Structure of electric scooter
An electric scooter mainly consists of the following parts:
1. Frame: The frame is the skeleton of an electric scooter. It is usually made of aluminum alloy or steel and has high strength and rigidity.
2. Battery: The battery of an electric scooter is mainly responsible for storing energy and providing it to the motor to drive the vehicle forward. Currently, there are three main types of lead-acid batteries, nickel-metal hydride batteries and lithium batteries on the market. Among them, lithium batteries have the advantages of small size, light weight and high energy density, and are currently the mainstream choice for electric scooters.
3. Motor: The motor is the power source of the electric scooter and is responsible for converting electrical energy into mechanical energy to drive the vehicle forward. According to the difference in power and torque, motors are divided into two types: brushed motors and brushless motors. Brushless motors have the advantages of high efficiency, low noise, and long life, and are currently the preferred type of electric scooters.
4. Controller: The controller is mainly responsible for adjusting the electric energy output by the battery to adapt to different driving needs. At the same time, the controller also has overload protection, short-circuit protection and other functions to ensure the safe and reliable operation of the electric scooter.
5. Braking system: The braking system mainly includes components such as brake handles, brake pads, and brake discs. It is responsible for decelerating or stopping the vehicle when the driver operates the brake handle. At present, the braking systems of electric scooters mainly include drum brakes and disc brakes.
6. Tires: Tires are the ground components of electric scooters and directly bear the weight of the vehicle and various impacts during driving. The tires of electric scooters are usually made of rubber material, which has good grip and wear resistance.
3. Performance of electric scooters
The performance of electric scooters is mainly reflected in the following aspects:
1. Maximum speed: Maximum speed refers to the highest driving speed that an electric scooter can reach within a certain period of time. The maximum speed of common electric scooters currently on the market is generally around 20-30 kilometers/hour.
2. Range: Range refers to the distance that an electric scooter can travel at a certain speed when fully charged until the battery is exhausted. The current range of common electric scooters on the market is generally between 40-70 kilometers.
3. Climbing ability: Climbing ability refers to the maximum climbing angle that an electric scooter can achieve during climbing. The climbing ability of common electric scooters currently on the market is generally between 10-20 degrees.
4. Charging time: Charging time refers to the time it takes for an electric scooter to be fully charged from a completely discharged state. The charging time of common electric scooters currently on the market is generally between 4-8 hours.
4. Selection of electric scooters
When purchasing an electric scooter, consumers should consider the following factors based on their actual needs and usage scenarios:
1. Brand: Choosing an electric scooter from a well-known brand can ensure the quality and after-sales service of the vehicle.
2. Price: Choose an electric scooter in a suitable price range according to your own economic conditions. Generally speaking, the higher the price of an electric scooter, the better its performance and configuration.
3. Power performance: Choose an electric scooter with the appropriate maximum speed, cruising range and climbing ability according to your own driving habits and needs.
4. Comfort: Test drive the electric scooter and check the vehicle’s handling, stability and shock absorption performance to ensure that you buy an electric scooter with good comfort.
5. Use and maintenance of electric scooters
In order to ensure the normal use of electric scooters and extend their service life, users should pay attention to the following points during use:
1. Charging: Before using the electric scooter, make sure the battery is fully charged. When charging, you should use a dedicated charger in accordance with the instructions to avoid battery damage caused by using an inappropriate charger. At the same time, attention should be paid to observing the charging status during the charging process to avoid overcharging or undercharging.
2. Driving: When driving an electric scooter, you should abide by traffic rules and avoid dangerous behaviors such as high-speed driving and sudden braking. At the same time, speed and braking force should be reasonably controlled based on road conditions and driving needs.
3. Maintenance: Perform regular maintenance on the electric scooter and check whether all parts of the vehicle are working properly. In particular, key components such as batteries, motors and braking systems should be inspected and maintained regularly. In addition, the vehicle’s exterior and tires should be cleaned regularly to maintain a good driving environment.
