Point

There are many types of electric vehicles. Depending on their purpose, structure layout, driving motors, and energy storage devices, they can be divided into different types of electric vehicles.

1. The structure characteristics of electric vehicles

Electric vehicles provide electrical energy from power batteries for power source to drive motors, and the drive system transforms electrical energy into mechanical energy as a power source driving vehicle. The operating conditions of the car are mainly implemented by the controller control motor. Pure electric vehicles are "zero emissions" cars. The main technical bottlenecks currently developed: the battery of power is limited by the anode material, low energy density, and short range of mileage; , Low cost performance. The schematic diagram of the pure electric vehicle structure is shown in Figure 19-1.

The composition of electric vehicles includes mechanical systems such as power -driven and control systems, driving power transmission, and working devices that complete the established tasks. The power -driven and control system is the core of electric vehicles, and it is also the biggest difference between internal combustion engine cars. Electric -driven and control systems are composed of driving motors, power supply and motor speed control device; other devices of electric vehicles are basically the same as internal combustion engines.

High -performance electric vehicles are usually designed and manufactured. It is based on the design of the original car body and frame to meet the unique structure requirements of electric vehicles and make full use of the flexibility of electric drive.

Compared with internal combustion engines, the structure of electric vehicles is flexible. This flexibility comes from the following unique characteristics of electric vehicles:

① The energy transfer of electric vehicles is mainly passed through flexible wires, not through rigid coupling and rotating shafts. Therefore, the arrangement of various components of electric vehicles has great flexibility.

② Using different types of motors (such as DC motors and AC motors) will affect the quality, size and shape of electric vehicles: different types of energy storage devices (such as batteries and fuel cells) will also affect the quality, size and shape of electric vehicles. The layout of the automotive driving system is different (such as an independent four -wheel drive system and a hub motor drive system, etc.), which will make the driving system structure very different.

③ The battery adopts different energy storage devices, and its layout form, location, and control methods are very different.

④ Different energy devices have different hardware and institutions. For example: The battery can be charged by induced and contact -type chargers, or the battery is used to concentrate the replaced battery.
