ECVT and CVT are basically the same in function, and both belong to continuously variable gearbox. The advantage of continuously variable transmission is to make the power output of the vehicle stable and give the owner and passengers a good driving experience. The working principle of CVT gearbox is to realize function adjustment through two sets of gears and steel belt clutches. The function of stepless speed change is realized by the speed difference between two gears. The working principle of CVT is simple, but it also has obvious shortcomings.
ECVT gearbox is specially developed for new energy vehicles and hybrid vehicles. ECVT realizes the balance between engine power and motor power through a gear and two motors, one large and one small. Therefore, the engine of the car will not directly drive the vehicle, but realize the power output through these two motors. The big motor is responsible for the forward power of the vehicle, and the small motor is responsible for the bicycle running without too much power. ECVT has no reverse gear.
