Abstract: The present invention discloses a battery assembly bracket, which comprises a hollow casing having accommodation spaces accommodating battery cells. The edges of every two opposite faces of the hollow casing have convex strips and engagement slots, whereby a plurality of hollow casings can be assembled together. Four corners of one bottom face of the hollow casing have fixing elements, whereby the battery assembly bracket can be fixed to a printed circuit board. The battery assembly brackets of the present invention can be flexibly assembled into different battery modules having different numbers of cells, different voltages and different capacities to satisfy different systems. The battery assembly bracket of the present invention not only can simplify battery assembly and reduce assembly manpower but also can decrease the number of molds, lower the fabrication cost and increase the economic benefits.

Abstract: The present invention discloses a battery assembly component, which comprises a sleeve set having a first sleeve element and a second sleeve element. The two sleeve elements respectively have accommodation spaces. The two sleeve elements are joined at a point on neighboring edges of the two sleeve elements. The inner rim of the first sleeve element and the outer rim of the second sleeve element are on the same plane, and the accommodation spaces of the two sleeve elements are parallel. In assembling, the second sleeve element of one sleeve set is arranged to coincide with the first sleeve element of another sleeve set. Next, a battery cell is placed into the interconnecting accommodation spaces. The assemblage of the battery assembly components can be infinitely expanded via repeating the abovementioned steps. Therefore, the present invention can assemble battery cells to obtain different battery modules providing different voltages and power outputs.

Abstract: Energy exchange equipment is disclosed, which can sell batteries that have been recharged already. A user can buy a new battery from the energy exchange equipment by using a smart card. If a user has an old battery, he can put this old battery in an energy tank on the energy exchange equipment and then extract a new battery. If a user has no old battery, he can directly extract a new battery. The energy exchange equipment then deducts a corresponding amount of money in the smart card based on the electric capacity difference between the extracted new battery and the old battery.
