Do New Energy Vehicles Have Engines?
3 Answers
New energy vehicles do not have engines, but they are equipped with electric motors. Working principle: Battery -> Current -> Power Regulator -> Electric Motor -> Power Transmission System -> Drives the vehicle (Road). Functions: An electric motor is a device that converts electrical energy into mechanical energy. It utilizes energized coils to generate a rotating magnetic field, which acts on the rotor to form a magnetoelectric power rotation torque. Classification: Electric motors are categorized into DC motors and AC motors based on the power source used. Most motors in power systems are AC motors, which can be either synchronous or asynchronous motors.
As a car enthusiast, I've test-driven quite a few new energy vehicles and found that pure electric cars completely lack traditional engines; they use battery packs and electric motors to drive the wheels, offering zero vibration at startup, incredibly fast acceleration, super quiet operation, and much simpler maintenance. Hybrid models are different, like the Honda Accord Plug-in, which has both an electric motor and a small engine for assistance, switching between them at high speeds or when the battery is depleted. From a technical standpoint, the core of pure electric vehicles is the electric drive system, eliminating components like fuel lines and exhaust pipes; this design reduces failure points and improves reliability, making them ideal for urban commuting. If you want to experience a completely new driving sensation, going pure electric is absolutely thrilling. Maintenance is also cheaper, with no need to worry about oil changes or spark plugs, but battery health management is crucial.
There's a pure electric commuter car in my neighborhood that I've been driving for over a year; it operates without any engine noise, propelled by two rear-wheel motors, making it quiet and smooth. Pure electric vehicles have zero engines, and charging is significantly cheaper than refueling. However, plug-in hybrid versions are different, like my neighbor's BYD hybrid, which runs on electricity for short trips and switches to a small backup engine for long distances. In daily use, engine-free new energy vehicles are hassle-free and fuel-efficient, costing just a few dozen yuan per charge to last several days with minimal maintenance headaches. The only drawback is needing to locate charging stations in advance, especially for long trips; but once you get used to it, it's highly practical, and I highly recommend it for family users to try.
