As shown in FIG. 1, the battery case 10 is a dry battery type battery case 10 having a positive terminal 11 and a negative terminal 12. The positive terminal 11 is used as an input or output port for the voltage and current of the dry battery type rechargeable battery structure 100, and the negative terminal 12 is used as a common reference for the dry battery type rechargeable battery structure 100 and the connected external circuits or components. The potential terminal (Common or Ground), the storage potential unit 20, the charging unit 30, and the reference potential terminal (Ground) of the conversion unit 40 are connected to the negative terminal 12.

The size of the battery case 10 is not particularly limited, but for ease of use, it may be selected to be the size of the No. 1 dry battery, the No. 2 dry battery, the No. 3 dry battery, or the No. 4 dry battery.

Similarly, as shown in FIG. 1 , the storage unit 20 of the dry battery type rechargeable battery structure 100 is used for storing a storage voltage, and the selection of the material of the storage unit 20 is not particularly limited. In order to facilitate the acquisition and control of the cost, the power storage unit 20 may choose to use a lithium battery or a lithium ion battery.

As shown in FIG. 1 , the charging unit 30 electrically connects the positive terminal 11 , the negative terminal 12 , and the storage unit 20 , and receives an external voltage from the positive terminal 11 and outputs a charging voltage to the storage unit 20 .
