Example

[0060]It should be noted that a difference between the ninth embodiment and the eighth embodiment is that, the positive terminals of the battery packs BP1 to BPn are respectively connected to the positive pins of the unidirectional conductive elements DB1 to DBn as shown in FIG. 8, but the negative terminals of the battery packs BP1 to BPn are respectively connected to the negative pins of the unidirectional conductive elements DB1 to DBn as shown in FIG. 10. In addition, as shown in FIG. 10, the positive pins of the unidirectional conduction elements DB1 to DBn are connected to a negative input terminal of the control circuit. A positive terminal of the battery pack BS1 is connected to a positive input terminal of the control circuit 100, and a negative terminal of the battery pack BS1 is connected to the positive terminals of the battery packs BP1 to BPn. An output terminal of the control circuit is connected to the light-emitting diode D0.

Abstract

A power supply device is provided, which includes a plurality of battery packs and a plurality of unidirectional conductive elements. The plurality of battery packs are connected in parallel with each other and disposed toward the same direction. The unidirectional conductive elements are connected in serial to the battery packs, respectively. A positive pin of each of the unidirectional conductive elements is connected in serial to a positive terminal of the corresponding battery pack, and a negative pin of each of the unidirectional conductive elements is connected in parallel to negative pins of other unidirectional conductive elements. Therefore, the present disclosure is capable of preventing the battery packs having relatively lower voltages from being charged by the battery packs having relatively higher voltages, thereby prolonging lifetimes of batteries, and avoid from affecting power to be supplied to a power receiving circuit from the battery packs.
