D03 pure electric vehicle

Compared with fuel vehicles, the main differences of Electric Vehicles are the four major components: drive motor, speed controller, power battery, and on-board charger. Compared with gas stations, it has public ultra-fast charging stations. The quality difference of pure electric vehicles depends on these four major components, and its value also depends on the quality of these four major components. The purpose of pure electric vehicles is also directly related to the selection and configuration of the four major components.

 

The speed and starting speed of pure electric Special Vehicles depend on the power and performance of the drive motor, and the length of its mileage depends on the capacity of the on-board power battery. The weight of the on-board power battery depends on the type of power battery used, such as lead-acid, zinc-carbon, lithium battery, etc. Their volume, specific gravity, specific power, specific energy, and cycle life are all different. This depends on the manufacturer's positioning and use of the whole vehicle grade, as well as the market definition and market segmentation.

 

 

The drive motors of pure electric Utility Vehicles are divided into DC brushed, brushless, permanent magnet, electromagnetic, and AC stepper motors, etc. Their selection is also related to the configuration, use, and grade of the whole vehicle. In addition, the speed control of the drive motor is also divided into stepped speed control and stepless speed control, and there are electronic speed controllers and no speed controllers. Electric motors include hub motors, inner rotor motors, single motor drives, multi-motor drives, and combined motor drives.
