Abstract

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.

Description

technical field [0001] The invention belongs to the field of energy recovery of automobiles, and in particular relates to a combined idling and braking energy recovery system of a storage battery and a flywheel. Background technique [0002] Due to the shortage of oil resources, energy saving has become a difficulty that the automobile industry must overcome; when the car is idling and braking, the energy of the car will be consumed, especially in urban working conditions, where the traffic flow is large and there are many traffic lights, it is necessary to often idle and wait. Brake braking, which will increase fuel consumption and cause energy waste. [0003] The current forms of energy recovery include battery and flywheel energy storage, etc., but generally only one of them is used. A single energy storage method has its own weaknesses. When using battery energy storage, all aspects of performance are better, but the power The density is low, the charging and dischargin...
