Structural Principles of Electric Vehicles

Composition of Electric Vehicle Structure without engine and gearbox, do you know what the structure of a pure electric vehicle is made of? How does it work?

we need to know about the concept of pure electric vehicles. A pure electric vehicle refers to a vehicle that obtains power from the on-board energy storage device, then meets the requirements of road safety laws driven by the motor, and is legally driving on the road.

It does not have the core components of a traditional internal combustion engine, an engine and a gearbox, but is replaced by a battery, an electric motor and an electronic control system. The motor is the heart of the electric vehicle, while the electronic control system is more like the brain of the electric vehicle. The battery stores the electricity needed to run the car, and the inverter converts the current from the battery pack from DC to AC, which is then used to power the electric traction motors. Because lithium-ion batteries can only accept direct current, while electric traction motors require alternating current to operate, an inverter is a necessary component on the electric drive. The electric traction motor receives power from the inverter, and when the alternating current reaches the motor through the inverter, it will generate a rotating magnetic field to make the motor rotate, convert the electric energy into mechanical energy, and provide power for the electric vehicle to drive. Unlike an internal combustion engine, having multiple gears to switch. As long as the frequency of the alternating current is changed, an electric vehicle can change the speed of the drive wheels, and has a very high response speed. The entire electrical powertrain of an electric vehicle, including the high-voltage electrical system that allows the vehicle to operate, the inverter traction motor, he shift drive and the traction battery pack. These electric powertrains are lightweight, compact, with minimal vibration and chrono torque, except for the three major components that are significantly different from gasoline vehicles. All is the same.
