Do New Energy Vehicles Have Engines and Transmissions?
1 Answers
They do not require a transmission and do not have an engine; instead, they use an electric motor. Below is an introduction to the advantages of electric motors: Stronger Control: Compared to internal combustion engines, electric motors have stronger control over power characteristics through input power. Taking the permanent magnet synchronous motor commonly used in pure electric vehicles as an example, it can output strong torque at zero speed as soon as the power is turned on, whereas internal combustion engines have concepts like starting and idling. High Efficiency: Electric motors strictly adhere to the formula "power equals torque multiplied by speed" from zero speed, eliminating the concept of starting—not pressing the accelerator equals stopping. The starting speed is already within the economical operating range, with permanent magnet synchronous motors averaging an efficiency of ninety percent.
