Abstract

The present disclosure provides an energy storage power supply. The energy storage power supply includes a housing and a plurality of cells. The housing has an accommodation cavity defined therein. The accommodation cavity is provided with a plurality of first fixing members at an inner wall of the accommodation cavity. Each of the plurality of first fixing members has a first through hole defined at a bottom wall of the first fixing member. The plurality of cells corresponds to the plurality of first fixing members in one-to-one correspondence. Each of the plurality of cells includes a body, a first pole, and a second pole. The first pole and the second pole are respectively disposed at two ends of the body in a length direction of the body. One of the two ends of the body is accommodated in a corresponding one of the plurality of first fixing members.

First claim

What is claimed is:

2 . The energy storage power supply according to claim 1 , wherein the first support and the housing are integrally formed.

3 . The energy storage power supply according to claim 1 , further comprising a second busbar connected to second poles of at least two of the plurality of cells.

4 . The energy storage power supply according to claim 1 , wherein the first busbar is covered with the cover plate.

5 . The energy storage power supply according to claim 1 , wherein the cover plate is connected to the housing through an adhesive within the receiving groove; or the cover plate is fixed to the housing through a fastener.

6 . The energy storage power supply according to claim 1 , further comprising a thermal conductive adhesive connected to the cover plate and the first busbar.

7 . The energy storage power supply according to claim 1 , further comprising a sealing ring sealingly connected to the cover plate and the outer side wall of the housing.

8 . The energy storage power supply according to claim 1 , wherein the housing comprises a first housing and a second housing, the first housing and the second housing being detachably connected to each other and enclosing the accommodation cavity, and the plurality of first fixing members being disposed on the first housing or the second housing.

9 . The energy storage power supply according to claim 1 , further comprising a panel disposed at the housing and configured to display an electric quantity of the current energy storage power supply.

10 . An energy storage power supply, comprising:
a housing having an accommodation cavity defined therein, the accommodation cavity being provided with a plurality of first fixing members at an inner wall of the accommodation cavity, and each of the plurality of first fixing members having a first through hole defined at a bottom wall of the first fixing member; and a plurality of cells corresponding to the plurality of first fixing members in one-to-one correspondence, each of the plurality of cells comprising a body, a first pole, and a second pole, the first pole and the second pole being respectively disposed at two ends of the body in a length direction of the body, one of the two ends of the body being accommodated in a corresponding one of the plurality of first fixing members, and the first pole being configured for an external connection by means of the first through hole; a first busbar disposed at outside of the accommodation cavity and connected to first poles of at least two of the plurality of cells; a second support located in the accommodation cavity and connected to the inner wall of the accommodation cavity, the second support being provided with a plurality of second fixing members, each of the plurality of second fixing members having a second through hole defined at a bottom wall of the second fixing member, the plurality of cells corresponding to the plurality of second fixing members in one-to-one correspondence, another one of the two ends of the body being accommodated in a corresponding one of the plurality of second fixing members; a cover plate, wherein the housing has a receiving groove defined at an outer side wall of the housing corresponding to the plurality of first fixing members, the first through hole passing through a bottom wall of the receiving groove, the first busbar being located in the receiving groove, and the cover plate being disposed at the outer side wall of the housing and covering the receiving groove; and a port configured to connect the energy storage power supply to an electrical device or a charging device; wherein the port is disposed on the housing; wherein a first support is disposed at the inner wall of the accommodation cavity, the plurality of first fixing members being disposed at the first support; wherein the first support comprises a surrounding wall connected to the inner wall of the accommodation cavity, the surrounding wall enclosing an accommodation groove in communication with the plurality of first fixing members.

11 . The energy storage power supply according to claim 10 , wherein the accommodation groove is injected with a fixing colloid fixedly connected to the plurality of cells and the first support.

12 . The energy storage power supply according to claim 10 , wherein the first support and the housing are integrally formed.
