Electric vehicles, namely electric vehicles, are also known as electric vehicles. electric vehicles are divided into AC electric vehicles and DC electric vehicles. Generally speaking, an electric vehicle is a vehicle in which a battery is used as an energy source, and electrical energy is converted into mechanical energy movement through a controller, a motor, and other components, so as to control the current and change the speed of the vehicle. The share of electric vehicles in the national economy is not very high. However, it conforms to the national trend of energy conservation and environmental protection and greatly facilitates short-distance transportation. The most important thing is that it plays an important role in the national economy by saving and protecting energy and the environment.

First of all, pay attention to the appearance of electric vehicles. The craftsmanship and level of the paint directly affect the first impression of this car. The paint materials include primer, topcoat, and varnish, and the quality of the paint can be judged according to the effect of the paint. Good baking paint has a transparent and bright surface, and the color is deep and natural. There should be no uneven color, chromatic aberration, and large areas of pitting or bumps. The applique process is smooth and the paint is evenly covered. Secondly, pay attention to the structure of electric vehicles. The basic units of electric vehicles are the frame, plastic parts, shock absorption, battery, controller, and motor. The quality of the frame is particularly critical. Many users don't care about the quality of the frame because it is difficult to observe this part. However, the quality of the frame directly determines the safety performance of the entire vehicle. In the final test run, drive at high speed and then make an emergency brake to see if the frame shakes from side to side. If the shake is severe, it means that the quality of the frame is not good enough and there is a potential safety hazard. Attention should be paid to the shock absorption effect of electric vehicles. Shock absorption is a key component that affects comfort. It is divided into front shock absorption and rear shock absorption. The choice of battery is also very important. A good battery can greatly reduce the later use and maintenance costs of consumers. Batteries are divided into lead-acid and lithium-ion batteries. The prices of batteries of different brands vary greatly, while for lithium batteries, the difference between different types is even greater, and the price difference between the second type of battery and the first type of battery is very different.
First, adjust the height of the saddle and handlebar of the electric bicycle to the safest and most comfortable position, especially the height of the saddle. It is best to have both feet on the ground at the same time when you need to stop during riding. Test whether the braking device is effective and reliable, and test whether the power supply is cut off and the motor has stopped working after braking. Check the battery level: When the power is turned on, it is important to watch the battery level on the monitor, especially when it is used after a long period of storage. In addition, it is necessary to check whether electric horns, lights, and other relevant driving safety components are effective. Check the electric vehicles’ rotating parts: whether the front and rear wheels, pedals, cranks, sprockets, chains, and flywheels are running normally, and whether there are foreign objects rubbing against them. Check whether the tire pressure is appropriate. When riding uphill, on the bridge, or against strong winds, both electricity and manpower should be used at the same time to reduce the load on batteries and motors. Riding method when starting: Generally, electric bicycles have a zero-start function, that is, when the electric bicycle is stationary, open the switch and turn the speed control knob to start the car. But the starting current at this time is two to three times that of normal driving, which has a great impact on the motor and battery, especially the battery. Therefore, in order to extend the mileage of a charge and the service life of the battery, the pedal should be started when starting, and the circuit should be connected after the pedal has a certain speed for three or four laps. This is especially true in heavy traffic and traffic lights. Lots of lots are especially important. Frequent zero starts will definitely shorten the life of the battery.
The screws and nuts that are fastened in the electric vehicle should be tightened, and should not be loose or fall off. All-electric vehicle rotating parts should operate flexibly, and there should be no jams or staleness. For example, the front and rear wheels should rotate flexibly, and they should not swing left and right and jump up and down. The wheels should be able to swing back and forth briskly when they are about to stop, and they should not stop turning suddenly. The handlebars should be flexibly turned left and right, the pedal shaft and the crank should be fastened, not loose between each other, and the turning should be flexible. The gear shift of the transmission car is correct within the gear shift range, the gear shift position should be clear, and there must be no neutral gear in the middle. The chain should be tight and flexible and run flexibly. The crank sprocket is shaken repeatedly by hand in forward and reverse directions, the chain runs flexibly, and there is no chain jumping or falling off. Hold the front and rear parts of the saddle with both hands, and press the front end of the saddle with one hand, so that the front end of the saddle must not collapse. Turn the saddle horizontally with both hands, and the saddle should not rotate.
