As shown in fig. 1 to 8, the energy storage power supply 100 of the present application includes a housing 1, a battery pack 2, an inverter 5, and at least two charging compartments 3. The battery pack 2 and the inverter 5 are disposed within the housing 1, and the inverter 5 is electrically connected to the battery pack 2 for ac/dc conversion of the current output from the battery pack 2. The housing 1 has a first side 11, the battery pack 2 has a first outer wall 211 opposite to the first side 11, a side of the inverter 5 adjacent to the first side 11 is substantially aligned with the first outer wall 211, thereby forming an installation space 10 between the battery pack 2, the inverter 5, the first side 11, and the top and bottom surfaces of the housing 1, and the plurality of charging compartments 3 are sequentially disposed in the installation space 10 in a vertical direction. The charging bin 3 allows an external battery cell 4 to be inserted therein for charging.

It is worth mentioning that since the side of the inverter 5 may not have a definite interface, the end face of the part thereof closest to the first side face 11 serves as an interface of the inverter 5 side for determining whether it is aligned with the first outer wall 211. In addition, the term "alignment" is not limited to a strict alignment, and allows slight deviation as long as the deviation does not substantially affect the overall volume of the energy storage power source, for example, a small portion of each component of the inverter 5 may extend beyond the first outer wall 211.

This application is through forming installation space 10 between group battery 2, inverter 5 and first side 11, with a plurality of storehouse 3 that charge along vertical direction setting in installation space 10, has realized the make full use of energy storage power 100 inner space. The battery pack 2 is a component which occupies a large volume and is heavy in weight in the energy storage power supply, and in order to ensure that the energy storage power supply 100 has good stability when being placed, the battery pack 2 is arranged at a position of the shell 1 close to the bottom, in addition, the overall size of the inverter 5 is also large, the inverter 5 is arranged above the battery pack 2, the side surface of the inverter 5 is basically aligned with the side surface of the battery pack 2, and the internal space of the shell 1 can be better utilized.

Each charging bin 3 is arranged on one side of the battery pack 2 and the inverter 5 in the vertical direction, and the charging bin is reasonably designed based on the shape of the charging bin 3, so that the best utilization of space is facilitated. Specifically, since the length of the battery pack 2 and the inverter 5 is usually greater than the height thereof, and the volume of the charging bin 3 is usually smaller, if the charging bin 3 is arranged above the battery pack 2 or the inverter 5 in sequence along the horizontal direction, it is difficult to fully utilize the space above, which causes waste of space; and will charge storehouse 3 and set up in proper order in installation space along vertical direction, then be favorable to reducing the waste in space. In addition, when the height of the battery pack 2 or the inverter 5 is high and there is still much remaining space after the plurality of charging compartments 3 are disposed in the installation space 10, a heat-dissipating fan 6 may be disposed in the installation space 10, and as shown in fig. 6, since the installation space 10 is close to the first side 11 of the housing 1, a ventilation opening 111 may be opened in the first side 11 to be opposite to the fan 6; the charging module 7 may be disposed in the installation space 10, as shown in fig. 8, since the installation space 10 is close to the first side 11 of the housing 1, a corresponding charging interface may be opened on the first side 11 to correspond to the charging module 7.

The battery unit 4 may be a battery pack, a portable power source, or the like, and is adapted to supply power to an external electric device separately from the charging chamber 3. In some embodiments, battery unit 4 is a battery pack adapted to be cordless coupled to a powered device to provide power to the powered device.

In some embodiments, the at least one charging bin 3 coincides with a projection of the battery pack 2 in a first direction from the first side 11 to the first outer wall 211 along a horizontal plane.

In some embodiments, the at least one charging bin 3 coincides with a projection of the inverter 5 in the first direction. It should be mentioned that the inverter 5 includes a circuit board and a plurality of components disposed on the circuit board, and the fact that the projection of the at least one charging bin 3 and the projection of the inverter 5 along the first direction overlap means that the projection of the at least one charging bin 3 and the projection of each component of the inverter 5 along the first direction overlap, which means that the at least one charging bin 3 is located at a height close to the height of the inverter 5.

In some embodiments, the mounting space 10 is strip-shaped, i.e. the height of the mounting space 10 in the vertical direction is larger than the distance between the first side 11 and the first outer wall 211.

The length of the battery pack 2 is greater than the height, which means that the battery pack 2 is substantially transversely disposed in the housing 1 of the energy storage power supply 100, so that the center of gravity of the battery pack 2 is as close as possible to the bottom surface of the energy storage power supply 100, which is beneficial to improving the stability of the energy storage power supply 100 when placed horizontally. Further, the length of the housing 1 along the X-axis direction is greater than the height of the housing 1 along the Z-axis direction, and the arrangement direction of the battery pack 2 is substantially consistent with the arrangement direction of the housing 1, so that the waste of the space in the housing 1 is reduced, and the volume of the energy storage power supply 100 is reduced.

In some preferred embodiments, the length of the housing 1 along the X-axis direction is greater than the width of the housing 1 along the Y-axis direction, which means that the third side 13 is the larger area of the sides of the housing 1 of the energy storage power supply 100, and thus, more functional modules can be arranged on the third side 13. Further, the length of the battery pack 2 in the X-axis direction is larger than the width thereof in the Y-axis direction.

Thus, the internal space of the housing 1 can be utilized to the maximum extent, and the waste of space is reduced. Since the length of the charging bin 3 is generally close to the thickness of the battery pack 2, the charging bin 3 is arranged along the Y axis, so that the space on the side surface of the battery pack 2 can be fully utilized, and the size of the housing 1 in the X axis direction and the Z axis direction is not excessively increased.

In some embodiments, the projections of the charging bins along the Z-axis direction substantially coincide.
