The invention relates to a storage battery and
flywheel combined type idling and braking
energy recycling system. Two
modes of storing energy through a storage battery and storing energy through a
flywheel are combined for
energy storage. An
electromagnetic clutch a and an
electromagnetic clutch b are controlled through an
electronic control unit to be engaged and disengaged, and a
power transmission route is controlled. When an automobile is started, the
electromagnetic clutch a is engaged, and a motor /
electric generator serves as motor output power to drive an engine
flywheel to rotate. When the automobile is braked, the electromagnetic
clutch a and the electromagnetic
clutch b are engaged at the same time, so that the engine flywheel drives the
energy storage flywheel to rotate to recycle braking energy in an
energy storage mode of the energy storage flywheel; and when the energy storage flywheel releases energy, the automobile is assisted in starting and acceleration, energy, left after starting, of the energy storage flywheel is recycled through the motor /
electric generator for power generation. In the idling process, the electromagnetic
clutch a is engaged, the motor /
electric generator serves as an electric generator for generating power, and energy consumed in the idling process is recycled. Idling and braking energy is recycled, so that energy waste is reduced, and the
fuel efficiency is improved.
