The electric vehicle is equipped with a driving unit electric unit 4. /, there is a wheel axle that can drive the electric vehicle,, w, a dry motor, a motor 31, a relay 32 electrically connected to the motor 31, and a motor 31 that can drive the motor 31 to operate The relay circuit 32 is electrically connected to the driving circuit μ, wherein the relay 33 can switch from the J to the driving circuit 33 to be electrically connected to the motor 31, and the wheel 2 2 m or the like drives the motor 31 to rotate the motor. 31 5 Generates electrical energy. As shown in FIG. 24, the power storage unit 4 has a battery 41' electrically connected to the driving circuit 33 of the driving unit 3, and a battery unit 42' electrically connected to the battery 41 and the motor 31 at least in this embodiment. The battery 41 is an early-charged battery, and of course, a plurality of rechargeable batteries may be connected in series, depending on actual needs, wherein the battery 42 has a storage element 421 electrically connected to the motor, and an electrical connection. The DC replacement wafer 422 ′ of the storage element 421 and the anti-backflow element 423 of the battery 41 are electrically connected to the DC replacement wafer 422 . According to the above configuration, when the electric vehicle is driven, the driving circuit 33 of the driving unit 3 is electrically connected to the motor 31 and the battery 41, and the driving circuit η drives the motor 3i to operate 'the battery 41 continues to provide the driving circuit ^ The required DC power (24V or 36V), at the same time, the relay 32 controls the motor 3! and the battery unit 42 is disconnected 'to make the battery 42 not yet generated; the battery 41 can be charged. When the driving circuit of the driving unit 3 33 stops driving the motor η to turn around, but the axle 2 of the electric vehicle continues to travel, the relay 32 controls the motor to open the drive circuit 33, and causes the motor 31 to electrically conduct the old appliance 42. The battery 41 also stops supplying power with the driving circuit. That is, the motor 31 is driven by the axle 2 to rotate the rotor in the Rida to generate electric energy output, and the two storage capacitors 42i are connected in series. Charging is performed, and after the storage element 421 is charged to the set value, the discharge is performed, and the electric energy therein is transferred to the direct change wafer 422, and then the DC exchange of the wafer is performed by the direct current exchange = 6 The M379529 is adjusted to a predetermined voltage (24V or 36V), and then the adjusted DC power is accumulated in the battery 41 to achieve the purpose of charging the battery 41. When the drive circuit 33 resumes the operation of the drive motor 31, the relay 32 controls the drive. The circuit 33 is disconnected from the battery unit 42. The DC-exchange wafer 422 is stopped, and is charged by the battery 41 to be discharged into the battery 41. At this time, the voltage of the DC-exchange wafer 422 is less than the voltage of the battery 4 J to generate a countercurrent. Therefore, by providing the anti-backflow element 423, the direct current of the battery 41 can be prevented from flowing back to the DC-exchange wafer 422 to achieve the effect of protecting the DC-exchange wafer 422. Here, the DC-exchange wafer of the embodiment is described. 422 is MC34063, the adjustable DC output is 6V~45V, but other similar products can be used. For example, DC swap chip 422 is LT3782 adjustable DC output is 6V~60V, because MC34063 is a DC-DC parent switch Convert 1C, in addition to the effects of voltage regulation, buck, and boost, it can also be converted to a negative voltage, and the price of MC34063 The low grid, simple circuit and low temperature rise not only reduce the cost of the electric vehicle feedback charging device of the present invention, but also simplify internal circuits and reduce component noise interference. Therefore, the driving unit 3 and the circuit of the power storage unit 4 When the electric vehicle is traveling, the circuit that controls the motor 31 by the driving circuit 33 and the circuit that is driven by the motor 31 to generate electric energy feedback charging are separated, and the signals are separated from each other. This reduces the noise interference and improves the accuracy of the circuit control, relatively improves the conversion efficiency of the electric vehicle b feedback, and further improves the endurance of the electric vehicle when traveling. 7 M379529 In summary, when the drive circuit 33 stops The motor 31 is driven to operate, and the motor 31 and the drive circuit 33 are disconnected, and the battery 41 is electrically connected. The motor 31 is used to start charging the battery 41. Compared with FIG. 1, it is known that the signal is received. The devices 12 and 12 receive the two signals as the judgment for charging. The novel design of the circuit is simplified, thereby reducing the interference of the component λ, thereby increasing the charging. To give back conversion efficiency, improve endurance of electric vehicles to travel, it can reach 4 real purpose of this novel. The above-mentioned ones are only the preferred embodiments of the present invention, and the scope of the present invention cannot be limited thereto, that is, the simple equivalent changes and modifications made by the novel patent application scope and the new description contents are all It is still within the scope of this new patent.
