Description

Technical Field

[0001] The present disclosure relates to the field of energy storage power supplies, and in particular to an energy storage device and a portable energy storage power supply. Background Art

Energy storage power supplies are a common device that can store electrical energy. They can power the required equipment in different places and are especially suitable for outdoor life.

[0003] For example, a Chinese patent with application number CN202222031704.8 discloses a portable energy storage power supply, which is provided with a protective component to limit the protective cover to the charging interface for sealing protection, thereby preventing the contact parts inside the charging interface and the components inside the energy storage power supply body from being damaged by moisture and dust during use, further improving the service life of the device, and by providing a cable clamping component, the charging connection cable can be sorted and stored, thereby improving the neatness during use and preventing the charging connection cable from dragging and tripping people walking around.

The surface heat dissipation of the outer shell of the energy storage power supply alone cannot meet the heat dissipation requirements of the large-capacity battery module. Once the battery cell temperature of the large-capacity battery module reaches 65°C, the battery cell will stop generating electricity, causing the energy storage power supply to be unable to be used normally.

[0042] The energy storage device 10 of one embodiment includes a power supply housing 100, a battery module 200 and a heat dissipation blowing member 300. A plurality of upwardly inclined vents 101 are provided on the outer wall of one end of the power supply housing 100, a plurality of downwardly inclined vents 102 are provided on the outer wall of the other end of the power supply housing 100, a battery limiting cavity 103 is provided in the power supply housing 100, a first air inlet gap 104 and an air inlet 105 are provided on one side of the battery limiting cavity 103, a second air inlet gap 106 is provided on the top of the battery limiting cavity 103, an air outlet gap 107 and an air outlet 108 are provided on the other side of the battery limiting cavity 103, and each downwardly inclined vent 102 is connected to the air outlet gap 107 and the air outlet 108.

Most of the air flows into the battery limiting cavity 103 from the first air inlet gap 104 and the air inlet 105 and contacts the battery module 200. A small portion of the air flows to the top of the battery limiting cavity 103 and rebounds from the inner top wall of the power supply housing 100 to the second air inlet gap 106 and contacts the battery module 200, so that the air can fully contact the battery module. 200, that is, the heat on the surface of the battery module 200 is absorbed by the air to form hot air, and the hot air then flows from the battery limiting cavity 103 to the plurality of downward vents 102 through the air outlet gap 107 and the air outlet 108, and the hot air is then discharged to the outside of the power supply housing 100 through the plurality of downward vents 102, which can effectively improve the heat dissipation performance of the energy storage device 10, avoid the battery module 200 from heating up too quickly when working, and ensure the normal use of the energy storage device 10.

[0044] Furthermore, the inclined setting of the upward vent 101 and the downward vent 102 has a better air guiding effect, and the upward vent 101, the battery limiting cavity 103 and the downward vent 102 form a through-type heat dissipation duct, and the heat dissipation blowing member 300 continuously outputs air to the through-type heat dissipation duct, so that the air can continuously and fully contact the battery module 200, so that the heat dissipation performance of the energy storage device 10 matches the heat dissipation requirements of the large-capacity battery module 200, and in terms of the appearance of the power supply shell 100, the components inside the power supply shell 100 cannot be seen from the upward vent 101 and the downward vent 102, so that the energy storage device 10 has a better aesthetics.

[0047] like Figures 3 to 6 As shown, in one embodiment, the energy storage device 10 further includes a circuit board 400, which is installed in the power supply housing 100, and the circuit board 400 is electrically connected to the battery module 200 and the heat dissipation blowing member 300, respectively.

[0051] like Fig. 9 and Fig.10 As shown, in one embodiment, the battery module 200 includes a battery box 210 and a plurality of battery components 220. The battery box 210 is disposed in the battery limiting cavity 103. The plurality of battery components 220 are disposed in the battery box 210, and the plurality of battery components 220 are electrically connected to the circuit board 400. It is understandable that the battery components 220 are embedded in the battery box 210, and the heat generated by the battery components 220 will also be transferred to the battery box 210. The battery box 210 is in full contact with the air, so that the heat generated by the battery module 200 during operation can be dissipated in time, avoiding the situation where the battery cell is disabled due to excessive operating temperature, and ensuring that the energy storage device 10 can be used normally.

[0056] Furthermore, the inclined setting of the upward and downward vents has a better air guiding effect, and the upward vents, the battery limiting cavity and the downward vents form a through-type heat dissipation duct. The heat dissipation blowing member continuously outputs air to the through-type heat dissipation duct, so that the air can continuously and fully contact the battery module, so that the heat dissipation performance of the portable energy storage power supply matches the heat dissipation requirements of the large-capacity battery module. In addition, the components inside the power supply shell cannot be seen from the upward and downward vents in the appearance of the power supply shell, so that the portable energy storage power supply has better aesthetics.

This can effectively improve the heat dissipation performance of the energy storage device, avoid the battery module from heating up too fast when working, and ensure the normal use of the energy storage device.

[0059] 2. The inclined setting of the upward vents and the downward vents has a better air guiding effect, and the upward vents, the battery limit cavity and the downward vents form a through-type heat dissipation duct.
