The above and other technical contents, features, and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments. Before the present invention is described in detail, it is to be noted that in the following description, similar elements are denoted by the same reference numerals. Referring to Figure 1, a first preferred embodiment of the charging system of the present invention includes a power source 1 and an oscillating module 2 for charging a secondary battery 3. The positive pole of the power source 1 can output the DC power to the oscillating module 2, and the negative pole of the power source 1 is grounded. The oscillating module 2 mainly includes a nonlinear element 21 having a negative resistance characteristic and an inductance-capacitance oscillating circuit 22.

For example, the charging state of the secondary battery 3 is determined to be charged or not. The charging system of the present embodiment further includes a measuring unit 4 and a system control unit 5. The measuring unit 4 is further electrically connected to the positive pole of the secondary battery 3 to detect the state of charge of the secondary battery 3 to transmit the detection result to the system control unit 5, where the measuring unit 4 measures the secondary battery 3 The state of charge (eg, voltage value or current value) is transmitted to system control unit 5.

The differential equation has a limit circle characteristic that allows the oscillation module 2 itself to oscillate to convert DC power into pulsed power for pulse charging. In addition, the present invention can further adjust the inductance value and the capacitance value of the inductor-capacitor oscillation circuit 22 to provide different oscillation frequencies. Thus, not only the oscillation frequency is adjustable, but also the circuit design complexity is simplified, thereby reducing the cost. Furthermore, the charging system of the present invention further utilizes the auxiliary current circuit 6 to increase the current during charging, which can reduce the required charging time and effectively improve the charging efficiency of the battery 3. However, the above is only a preferred embodiment of the present invention, and does not limit the scope of implementation of the present invention by 13 1373898, that is, the simple equivalent of the scope of the invention and the description of the invention. Variations and modifications are still within the scope of the invention.
