Embodiment Construction

[0022] Regenerative energy refers to energy temporarily accumulated in the form of other types of energy converted from kinetic energy possessed by the vehicle using a regenerative brake when an electric motor is decelerated during its running and reused upon vibration or acceleration of machinery.

[0023] Examples of the form of energy accumulated as regenerative energy include kinetic energy of a flywheel or accumulated energy of an accumulator. Usually, a drive motor for traveling of a vehicle or a construction machine is used. During traveling operation or work of the construction machine, when the electric motor is decelerated, the generator operates the driving motor for traveling so that electric power generated while operating the driving motor is stored in the energy storage system.

[0024] Regenerated energy will be described with reference to an example of a hybrid system used in a vehicle. The vehicle's electric motor is also used as a generator and produces a p...
