The phrase appears at various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0043] Phase change energy storage devices utilize the advantages of high thermal enthalpy and high energy storage density of phase change energy storage materials to store electrical energy or thermal energy in the phase change energy storage materials of phase change energy storage devices. Currently, most phase change energy storage devices absorb heat through the dissolution of crystal water. When the temperature rises, the crystal hydrate salt is lost. When the temperature drops, the reverse process occurs, absorbing crystal water and releasing heat. However, the energy storage devices in the current related technologies can only achieve heat storage or cold storage, and cannot achieve energy storage and heat storage at the same time.

[0044] In view of this, the present embodiment provides an energy storage device, which can store energy and heat simultaneously.

[0045] See also Figure 1 , an energy storage device 100, comprising: a housing 10, a phase change energy storage element 20, a compressor 30, a heat dissipation component 40, and an energy regulation component 50;

[0046] The housing 10 is provided with a heat dissipation component 40 and a phase change energy storage component 20, the compressor 30 is connected to the heat dissipation component 40, a heat exchange medium is provided in the heat dissipation component 40, the compressor 30 is used to compress and drive the heat exchange medium to circulate, and the compressor 30 is provided outside the housing 10;

[0047] The energy regulating component 50 is connected to the heat dissipating component 40 . The energy regulating component 50 is disposed outside the housing 10 . The energy regulating component 50 is used to replenish energy to the phase-change energy storage element 20 or to release energy.

[0048] The energy storage device 100 includes a housing 10, in which a heat dissipation component 40 and a phase change energy storage element 20 are arranged, and a compressor 30 is arranged outside the housing 10, and the compressor 30 is connected to the heat dissipation component 40; the compressor 30 arranged outside the housing 10 can drive the heat exchange medium in the compressor 30 to flow, so that the heat dissipation component 40 generates heat or cold, so that the energy storage device 100 can store cold or heat; an energy regulating component 50 is also arranged outside the housing 10, and the energy regulating component 50 is connected to the heat dissipation component 40. When the environment When the temperature is higher than the temperature inside the shell 10, the energy regulating component 50 can absorb the heat outside the shell 10 and conduct it to the heat dissipation component 40, so that the energy storage efficiency of the phase change energy storage component 20 can be improved through the cold amount regulating component; the energy regulating component 50 can also achieve heat dissipation. When the ambient temperature is lower than the temperature in the shell 10, the phase change energy storage component 20 in the shell 10 can release heat and the heat released by the phase change energy storage component 20 can be exported through the energy regulating component 50, so that energy storage or energy release can be achieved simultaneously through the energy regulating component 50.

[0049] See also Figure 2, in some embodiments, the heat dissipation assembly 40 includes: a first heat dissipation member 41 and a second heat dissipation member 42;

[0050] The housing 10 has a first accommodation cavity 11 and a second accommodation cavity 12; wherein, the first heat dissipation member 41 is disposed in the first accommodation cavity 11, the second heat dissipation member 42 is disposed in the second accommodation cavity 12, and a phase change energy storage member 20 is disposed in both the first accommodation cavity 11 and the second accommodation cavity 12;

[0051] The compressor 30 is connected to the first heat dissipation member 41 and the second heat dissipation member 42, and a heat exchange medium is disposed in both the first heat dissipation member 41 and the second heat dissipation member 42. The compressor 30 is configured to compress and drive the heat exchange medium to circulate between the first heat dissipation member 41 and the second heat dissipation member 42.

[0052] It can be understood that the interior of the housing 10 is divided into a first accommodation cavity 11 and a second accommodation cavity 12; a first heat dissipation member 41 is disposed in the first accommodation cavity 11, and a second heat dissipation member 42 is disposed in the second accommodation cavity 12. In this way, the phase change energy storage member 20 in the first accommodation cavity 11 can store heat or cold, and similarly, the phase change energy storage member 20 in the second accommodation cavity 12 can also store heat or cold; the compressor 30 is connected to the first heat dissipation member 41 and the second heat dissipation member 42. In this way, the compressor 30 can drive the heat dissipation medium to flow in the first heat dissipation member 41 and the second heat dissipation member 42, so that the first heat dissipation member 41 generates heat or cold, and the second heat dissipation member 42 generates heat or cold; when the phase change energy storage member 20 in the first accommodation cavity 11 stores heat, the phase change energy storage member 20 in the second accommodation cavity 12 stores cold, and when the phase change energy storage member 20 in the first accommodation cavity 11 stores cold, the phase change energy storage member 20 in the second accommodation cavity 12 stores heat; the phase change energy storage member 20 can be attached to the first heat dissipation member 41 and the second heat dissipation member 42. In this way, when the first heat dissipation member 41 and the second heat dissipation member 42 generate cold, the energy storage of the phase change energy storage member 20 can be realized.

[0053] It can be understood that the high-temperature and high-pressure gas generated by the compressor 30 needs to be cooled when flowing to the first heat dissipation member 41. Therefore, it will release more heat, which can heat up the first heat dissipation member 41 in the first accommodation cavity 11 to store heat for the phase change energy storage member 20 disposed in the first accommodation cavity 11; before the high-temperature and high-pressure gas enters the second heat dissipation member 42, it first enters the second heat dissipation member 42 through a throttle valve and becomes a low-temperature liquid. Therefore, the heat exchange medium in the second heat dissipation member 42 needs to absorb heat, which can cool down the second accommodation cavity 12 to realize the refrigeration of the second accommodation cavity 12.

The heat - releasing component 51 is connected to the first heat - dissipating member 41 and the second heat - dissipating member 42. When the ambient temperature is lower than the temperature of the phase - change energy - storage member 20, the phase - change energy - storage member 20 can release heat, and the released heat can be collected by the first heat - dissipating member 41 and the second heat - dissipating member 42 and released through the heat - releasing component 51.
