First, we look at the appearance, that is, look at the plastic parts of the car, beat the plastic shell, if the sound is strong, prove that the shell is thick, will be durable. Then look at the appearance of the paint, is not even, if the color is very light, perhaps the car is in stock, put for a long time. Next we can see whether the shell splicing is cracked, screw what has not tightened, this is also a standard to consider workmanship. After looking at the outside, we can see if there is uneven welding and paint removal on the inside of the car, if the paint removal is serious, it may be a refurbished car.

After watching the appearance, it is the four largest electric vehicle, battery, motor, battery charger and controller. Batteries are the first of the four components of an electric car, and their important position can be imagined. When we buy a new car, we can look at the voltage of the battery. Best of all, the original batteries or big brand batteries are usually marked with electric cars. After looking at the battery we can see the motor, after power on, we can ride to listen to whether the motor noise, and can see whether the motor is above the brand name of electric vehicles, general genuine electric vehicles are self-developed motors, there will be their own brand identity. Next is to look at the core components of the electric vehicle controller, a better controller has been used will not be hot, the controller will also have the original nameplate. There are regular large factories out of the electric vehicle controller wiring is very neat. Finally, the charger, the original charger will be above the car brand logo, there are also national quality certification standards. The most important thing is not to take the wrong charger, it must be the same as the electric vehicle battery voltage.
