The technical principle of electric vehicle
Oct 18, 2018

Pure electric vehicles replace the fuel engine with an electric motor, which is driven by a motor without an automatic gearbox.

Compared to automatic transmission, the motor has simple structure, mature technology and reliable operation.

Traditional internal combustion engines can limit the speed of high-performance torque in a narrow range, which is why traditional internal combustion engine vehicles need a large and complex variable speed mechanism, and the motor can be in a fairly wide range of speed to produce torque, in the course of pure electric vehicles do not need to shift gear, easy to operate, low noise.

Compared with hybrid vehicles, pure electric vehicles use a single electrical energy, electronic control system greatly reduces the automotive internal mechanical transmission system, the structure is more simplified, but also reduces the friction caused by mechanical components of energy loss and noise, saving the car interior space, weight. Motor Drive control system is the main execution structure of new energy vehicle, the driving motor and its control system is one of the core components of new energy vehicle (battery, motor, electric control), and its driving characteristic determines the main performance index of the automobile, it is an important part of electric vehicle. The three categories of fuel cell vehicle FCV, HEV and EV in electric vehicles need to use electric motors to drive the wheels, choosing the right motor is an important factor to improve the cost-performance of all kinds of electric vehicles, so research and development can meet the requirements of the vehicle driving process, and has a strong and durable , low cost, high efficiency characteristics of the motor drive mode is extremely important.
