1. When an
Used Car is driving, the mechanical energy provided by the power unit is mainly consumed in the following aspects: the efficiency loss of the process of converting energy into mechanical kinetic energy. For internal combustion engines, it is manifested as engine thermal efficiency, and for electric motors, it is battery discharge efficiency, inverter efficiency and motor efficiency.
2. Internal friction consumption of the transmission mechanism. The mechanical energy provided by the internal combustion engine and the engine is consumed to a certain extent in the internal structural friction of the transmission gear shaft, etc. However, compared with
Fuel Car,
Used Electric Car have a smaller loss in this part due to the streamlined structure of the Used Car transmission device.
3. Solve the friction resistance of the road and the friction resistance for power consumption. When driving at a constant speed on a well-level road, the car consumes all the surrounding calories to solve the friction resistance of the road and the friction resistance. As the speed increases, both friction resistances increase, and the proportion of friction resistance increases with the speed.
