Battery flywheel integrated energy storage device

The invention discloses a battery flywheel integrated energy storage device which is mainly composed of a shell, a stator, a rotor frame, a battery carrier, a battery pack, a rotor coil, a controller and charge and discharge circuit and bearings. The battery flywheel integrated energy storage device has four working states of a flywheel mechanical energy storage state, a battery pack energy storage state, a kinetic energy output state and an electric energy output state so that mechanical energy can be stored, the stored mechanical energy can be converted into electric energy stored in the battery, and the problem of energy loss of pure flywheel energy storage for a long time can be overcome. 本发明公开了种电池飞轮综合储能装置，主要组成包括壳体、定子、转子架、电池架、电池组、转子线圈、控制器与充放电电路和轴承。本发明所公开的电池飞轮综合储能装置具有飞轮机械储能状态、电池组储能状态、动能输出状态和电能输出状态四种工作状态，可以对机械能进行存储，可以将所存储的机械能转化为电池中存贮的电能，克服长时间单纯飞轮储能的能量损耗问题。
