Do pure electric vehicles have transmissions?
3 Answers
Pure electric vehicles do not have transmissions. Most pure electric vehicles only have a reducer, which can reduce speed and increase torque, allowing the car to operate normally. Currently, pure electric vehicles are basically composed of an electric drive control system, auxiliary systems, chassis, and body. Most other new energy vehicles also adopt a similar structure, only replacing the electric drive control system with other energy sources, such as hydrogen energy, solar energy, etc. Many chargers for pure electric vehicles are not designed to withstand high vibrations. Therefore, after vibration, the charger may experience abnormal charging conditions. It is recommended that owners protect their vehicle's charger by wrapping it in plastic foam as much as possible. When charging, try to charge in a ventilated environment to avoid overheating of the charging plug during the charging process.
As someone who frequently tinkers with car mechanics, I believe pure electric vehicles indeed don't have traditional transmissions. Electric motors inherently provide high torque from zero RPM, eliminating the need for multi-gear transmissions to adjust speed and power like gasoline cars. They connect directly to the wheels, with only a single-speed reduction gear in between, simplifying the entire drivetrain. After driving electric vehicles a few times, what I love most is the smooth acceleration without any gear shift jerks, with power always readily available. Although a few models like the early Tesla Model S experimented with two-speed designs, the high cost and failure rates have led most to revert to single-speed setups. This greatly benefits reliability—no worries about clutch wear or gear failures, plus the system is more compact, efficient, and saves space and weight. In short, the absence of a transmission makes electric vehicle engineering simpler and more reliable, while also making driving easier.
My experience driving an electric vehicle is completely free from the worries of a transmission. From start-up to high speed, the electric motor directly drives the wheels, delivering power smoothly and continuously without the need for gear shifts. This makes the driving process as smooth as silk, eliminating the jerky feeling often experienced in gasoline cars, especially during stop-and-go city driving. Many friends are curious about the design of electric vehicles, and I explain to them that it stems from the electric motor's ability to operate efficiently across a wide range of speeds, eliminating the need for a transmission to balance power output. Only a few high-performance models like the Porsche Taycan are equipped with a two-speed transmission to enhance acceleration from a standstill, but the vast majority of brands, including Tesla and NIO, use a single-speed reduction setup. This design also improves charging efficiency, reduces energy loss, and extends range. Overall, the electric vehicle's drivetrain is simpler, making it easier for new drivers to adapt quickly.
