It receives energy from the battery. 2) ICE mode where the clutch is engaged and the ICE is coupled to the driveshaft. 3) Hybrid mode where the ICE rotates a generator (MG1), which charges the battery from which a motor (MG2) gets power to propel the vehicle. https://www.youtube.com/watch?v=QLUIExAnNcE In contrast the Toyota eCVT transaxle has a planetary gear set at its core that acts as a power split device with seamlessly shifting flows of energy from the battery to the wheels, from the ICE to the wheels and the battery via the generators and from the wheels to the battery via the generators. It has two motor-generators, the larger one of which is connected to the driveshaft and the smaller one t
