What is the Principle of Pure Electric Vehicles?
2 Answers
Pure electric vehicles operate on the principle that the driver controls the electronic accelerator pedal, sending analog electronic signals to the controller or processor. The controller or processor then processes these signals to regulate the motor's output power, speed, and direction of rotation. A pure electric vehicle is defined as a vehicle powered by an onboard power source, using an electric motor to drive the wheels, and meeting all road traffic and safety regulations. It consists of an electric drive and control system, along with a drivetrain mechanical system. The maintenance methods for pure electric vehicles include: 1. Inspecting the vehicle's paint for damage, the functionality of lights, the wear level of wiper blades, and tire wear and pressure; 2. Replacing the cabin air filter; 3. Checking and replenishing coolant, brake fluid, and windshield washer fluid; 4. Inspecting the power system's connectors and the insulation protection of wiring.
I've been driving a pure electric vehicle for a while, and its working principle is quite simple: there's a large battery at the bottom of the car that stores electrical energy. When you press the accelerator pedal, the controller acts like a brain, directing electricity from the battery to the motor. The motor then rotates to directly drive the wheels and propel the car forward. The entire system is very quiet, with smooth acceleration from a standstill, unlike gasoline cars that vibrate or make a lot of noise. Charging is also convenient—just plug it into a home socket at night or use a charging station, and it's ready in a few hours. Daily commuting costs are low and environmentally friendly. The only thing to watch out for is battery maintenance—avoid leaving it at full charge or completely discharged for long periods to prevent shortening its lifespan. In winter, the range may decrease slightly in low temperatures, but regular checks can ensure it lasts longer. I really like this design—it eliminates the engine and transmission, making maintenance simpler. Upkeep mainly involves changing tires and checking brakes and such.
