Abstract

The present invention provides a power system, a conveying device and an operation method of the power system. In the power system comprising internal combustion engine, a motor, a generator and two power storage devices, the electric power of the two power storage devices can be used in an appropriate manner, at the same time, the power of the motor and the generator is transmitted to a driven load. The power system 1 includes: the internal combustion engine 2, the motor 3, the generator 4, a power transmission mechanism 5, a control device 8 and the two power storage devices (6a, 6b). The control device (8) has a function of executing the first control processing which enables the power operation of the motor 3 and the generator 4 and transmits the power both of the motor 3 and the generator 4 to the driven load (DW), and in the first control processing, the electric power both of the first power storage device 6a and the second power storage device 6b is used to supply power to themotor 3 and the generator 4.

Description

technical field [0001] The present invention relates to powertrains used in hybrid vehicles and the like. Background technique [0002] Among hybrid vehicles, conventionally known are hybrid vehicles equipped with a power system including an internal combustion engine, a first motor / generator, and a second motor / generator as shown in Patent Documents 1, 2, and 3, for example. Furthermore, Patent Documents 1 and 2 describe a hybrid vehicle equipped with two power storage devices as power sources for a second motor / generator used as a drive source for traveling. [0003] prior art literature [0004] patent documents [0005] [Patent Document 1] Japanese Patent No. 4179351 [0006] [Patent Document 2] Japanese Patent No. 5772781 [0007] [Patent Document 3] Japanese Patent No. 5842486 [0008] In the power system as described above, it is desired to be able to drive passive loads (drive wheels in hybrid vehicles) with sufficient power without using the power of the intern...
