The invention discloses an electromechanical flywheel hybrid power system of an electric automobile. The electromechanical flywheel hybrid power system comprises a speed reduction device, a differential mechanism, an electric drive stepless speed change device, an electromechanical flywheel energy storage device, an electric drive stepless speed change device controller, an electromechanical flywheel energy storage device controller and a battery. The electric drive stepless speed change device dynamically couples a first motor, a power input shaft and a flywheel together, the control strategyis simple, power distribution is reasonable and effective, transmission is stable and efficient, the jerking feeling during mechanical braking is reduced, and the whole vehicle comfort can be effectively improved. Energy stored by the flywheel can directly output kinetic energy or be stored in the battery or directly drive an adjustable-speed motor, the rotating speed and torque of a gear ring and the flywheel are controlled through the electric drive stepless speed change device controller and the electromechanical flywheel energy storage device controller respectively, and adjustment of therotating speed and torque of the power input shaft is achieved to meet different driving requirements.

    本发明公开了一种电动汽车机电飞轮混合动力系统,包括减速装置,差速器,电驱无级变速装置,机电飞轮储能装置,电驱无级变速装置控制器,机电飞轮储能装置控制器和电池;电驱无级变速装置将第一电机,动力输入轴和飞轮三者动力耦合在一起,控制策略简单,功率分配合理有效,传动平稳且传动效率高,降低机械制动时的顿挫感,能够有效改善整车舒适性。飞轮储存的能量可直接输出动能也可存储到电池或直接驱动调速电机,通过电驱无级变速装置控制器和机电飞轮储能装置控制器分别控制齿圈和飞轮的转速和转矩,实现动力输入轴的转速和转矩调节,以匹配不同驾驶需求。
