The present invention should be clearly and fully disclosed herein, and those skilled in the art to which the invention pertains can understand the contents and implement them. Therefore, in FIG. 1, FIG. 2, and FIG. The two sets of power devices 12 and 14 are exemplified. However, according to the technical idea of the present invention, the parallel discharge adjusting device 10 of the present invention can also connect a larger number of the first power device 12 and the second power device 14 in parallel. At this time, the first discharge adjusting circuit 18 and the second discharge adjusting circuit 20 need only correspond to the same number of the first electric energy device 12 and the second electric power device 14.

Next, the present invention can be exemplified by a method embodiment. Referring to FIG. 4, a schematic flow chart of the discharge adjusting method of the present invention, and referring to FIG. 2, as shown in the figure, a discharge adjusting method of the present invention includes The following steps, in step S10, selectively receiving the first current I ₁ and the second current I ₂ from the two power devices, and then, according to step S12, adjusting the first according to the first preset current and the second preset current The flow rate of the current I ₁ and the second current I ₂ is selectively adjusted to flow into the power device 16 in step S14 by adjusting the first current I ₁ and the second current I ₂ .

According to the discharge regulation method of the present invention, the flow rates of the first leakage current I _L1 and the second leakage current I _L2 and the first discharge current I _D1 and the second discharge current I _{D2 are} based on the first regulation controller 22 and the The second adjustment controller 24 is controlled by the first switch S ₁ and the second switch S ₂ , and the first adjustment controller 22 determines the number of times the first switch S ₁ is turned on according to the first preset current, and the second adjustment The controller 24 determines the number of times the second switch S ₂ is turned on according to the second preset current.

Therefore, when the first leakage current I _{L1 is} less than the first preset current, the first adjustment controller 22 may increase the on-time ratio of the first switch S ₁ to increase the flow rate of the output first leakage current I _L1 when the first leakage When the current I _{L1 is} greater than the first preset current, the ratio of the on-time of the first switch S ₁ is reduced to reduce the flow rate of the output first leakage current I _L1 , and when the first leakage current I _L1 is equal to the first preset current, the constant A switch S _{1 is} turned on to proportionally to stabilize the flow of the first leakage current I _L1 .

When the second leakage current I _{L2 is} less than the second preset current, the second adjustment controller 24 may increase the on-time ratio of the second switch S ₂ to increase the flow rate of the output second leakage current I _L2 when the second leakage current I when _L2 is greater than the second preset current, reducing the conduction time ratio of the second ₂ switch S, a second output in order to reduce the leakage current I _L2 of the flow, when the second leakage current I _L2 is equal to a second predetermined current, a second switch constant The S ₂ conduction time ratio is used to stably output the flow rate of the second leakage current I _L2 .

Furthermore, the first preset current and the second preset current disclosed in the present invention are set from the rated current conditions of the first power device 12 and the second power device 14, but the technical feature is only the present invention. The embodiment of the present invention is not limited thereto. According to the technical idea of the present invention, another adjustment mode may be cited, so that the first preset current and the second preset current can be simultaneously considered. The actual conditions of the rated currents of the first power device 12, the second power device 12, and the power device 16 are set, and the first adjustment controller 22 and the second regulation controller 24 control the on-time ratio substantially as described above.

As shown in FIG. 2, another embodiment of the present invention is adjusted, its technical content is that when the first discharge current I _D1 smaller than the first predetermined current, a first regulation controller 22 may increase the first switch S ₁ is on-time ratio In order to increase the flow rate of the output first discharge current I _D1 , when the first discharge current I _{D1 is} greater than the first preset current, reduce the on-time ratio of the first switch S ₁ to reduce the flow rate of the output first discharge current I _D1 , When the first discharge current I _D1 is equal to the first preset current, the first switch S _{1 is} turned on for a proportional time ratio to stably output the flow rate of the first discharge current I _D1 .

When the second discharge current I _{D2 is} less than the second preset current, the second adjustment controller 24 may increase the on-time ratio of the second switch S ₂ to increase the flow rate of the output second discharge current I _D2 when the second discharge current I when _D2 is greater than the second preset current, reducing the conduction time ratio of the second ₂ switch S, to reduce the output flow of the second current I _D2 of the discharge, when the second discharging current I _D2 equal to the second predetermined current, a second switch constant The S ₂ conduction time ratio is used to stably output the flow rate of the second discharge current I _D2 .

The flow rate does not exceed the limit of the rated current of the power device 16, and as such, the power device 16 can be prevented from being over-discharged, thereby reducing the chance of damage or loss of life of the power device 16 due to excessive charging and discharging.

In addition, in the discharge adjusting method of the present invention, the first leakage current I _L1 and the second leakage current I _{L2 are} adjusted by the first adjustment controller 22 and the second adjustment controller 24 by pulse width modulation technology. The first switch S ₁ and the second switch S _{2 are} triggered. The first power device 12 and the second power device 14 are batteries or generators, and the power device 16 is an electric motor, a DC power device, or a power network. The foregoing electrical device may be information, communication, air conditioning, lighting, mechanical power or other power system, and the power network is an electrical load network composed of the above-mentioned power system. The first switch S ₁ and the second switch S ₂ are bipolar transistors, field effect transistors, insulated gate bipolar transistors or switched switches.

In summary, the parallel discharge adjusting device 10 according to the present invention can be applied to two sets of the first electric energy device 12 and the second electric energy device 14 or above to directly supply power to the power device 16 in parallel, in parallel. The discharge adjusting device 10 can be suitably used in parallel with a battery pack having different battery core characteristics. For example, a lithium manganese battery and a lithium iron phosphate battery can be used in parallel without any first electric power device 12 or second due to a difference in characteristics. The rated current of the electrical energy device 14 exceeds the range of the electrical energy device 14 and can be used in parallel between the first electrical energy device 12 or the second electrical energy device 14 of different capacities, for example, 10 ampere-hours and 20 ampere-hours of different rated currents. The device 12 or the electrical energy device 14 can be used in parallel, or the first electrical energy device 12 or the second electrical energy device 14 in different charging capacity states can be used in parallel, for example, a fully charged first electrical energy device 12 and the remaining half of the electrical energy The two electrical energy devices 14 can be used in parallel.

In addition, for electric vehicles, the riding distance of electric vehicles has a considerable relationship with the capacity of the battery pack, but the battery pack is difficult to move when it is large in size, so the volume and weight that can be extracted by ordinary people will also be limited.
