Difference between the transmission system of a pure electric vehicle and that of an internal combustion vehicle

Pure electric vehicle drivetrain and combustion vehicle drivetrain in the body structure and appearance is basically the same, but the two biggest difference is the power, drive system is different. Traditional cars use diesel or gasoline, while electric cars use greener electricity. The traditional power of the car is still the mainstream.

1, pure electric vehicles to on-board power as a power source, while the traditional internal combustion engine cars are fuel as a power source.

2, pure electric vehicles with power motors instead of combustion engines to drive the vehicle driving; pure electric vehicles to high-voltage high-current power system. While the traditional internal combustion engine cars, in addition to the ignition system with high voltage and low current, the other power supply are low-voltage weak power system.

3, pure electric vehicles mainly include drive motors, power batteries and electronic control systems, chargers, DC/DC and other major high-voltage electrical appliances.

4, electric car is a vehicle powered by on-board power supply, motor-driven wheel driving, in line with road traffic, safety regulations of the requirements of the vehicle, its working principle is: battery - current - power regulator -motor - power transmission system - drive the car driving.

5, electric vehicles are: pure electric vehicles, hybrid vehicles, fuel cell vehicles.

6, the working principle of the driveline, the engine work is concentrated in the "crankshaft", from the crankshaft through the clutch into the "gearbox", after the gearbox "speed ratio" output to the driveshaft, and then to the transmission of the car. The crankshaft passes through the clutch into the gearbox, and after the gearbox's "speed ratio" is output to the driveshaft, driving the tires. The working principle of the engine is "suction, pressure, explosion, exhaust" to complete a cycle of work.
