Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of household energy storage box, especially to a direct current high voltage household energy storage box. BACKGROUND

[0002] The energy storage system high voltage box is a high voltage power circuit control unit designed for an energy storage system. The energy storage high voltage box is responsible for connecting the energy storage battery pack with the external power system, realizing the input and output of electric energy. It can receive electric energy from the power grid or renewable energy power generation system and store it in the energy storage battery; at the same time, it can also deliver the electric energy in the energy storage battery back to the power grid or supply it to the load. The electric energy is distributed to different electrical equipment and systems to ensure the normal operation of each part.

[0003] The energy storage high voltage box is usually placed in a cool environment and cooled through the heat dissipation holes on the box shell. With the development, there are higher requirements for the speed and quality of construction site construction. In order to reduce the line that needs to be connected with the city power before construction, the energy storage high voltage box is gradually applied to the construction site power distribution. However, the buildings on the construction site are mainly prefabricated board houses, which lack enough cool and ventilated environment for the storage of traditional energy storage high voltage boxes.

[0004] Therefore, there is an urgent need for an energy storage high voltage box with excellent heat dissipation performance. SUMMARY

[0005] To solve the above problems, the utility model provides a direct current high voltage household energy storage box, and the utility model is realized as follows:

[0006] A direct current high voltage household energy storage box comprises:

[0007] A main box body is provided with an openable hatch door rotatingly arranged thereon, and the inside of the main box body is divided into a control cabin above a horizontally arranged partition plate and a battery cabin below the partition plate. A high voltage box is detachably arranged in the control cabin, and a plurality of battery boxes are detachably and stacked arranged in the battery cabin. A louver heat dissipation opening is arranged at the corresponding position of the hatch door and the control cabin.

[0008] The temperature control system comprises an industrial air conditioner embedded on the hatch, the industrial air conditioner comprises a compressor, an outdoor fan outside the outer wall of the hatch and an indoor fan inside the inner wall of the hatch, two groups of heat dissipation fin groups are arranged at the air outlets of the indoor fan and the outdoor fan respectively, the condenser heat exchange pipeline of the compressor passes through the two heat dissipation fin groups, and a duct mechanism is further arranged on the inner wall of the hatch, the duct mechanism comprises a cover body, the cover body covers the indoor fan and the heat dissipation fin group inside the inner wall of the hatch, and a plurality of air ducts are arranged on the surface of the cover body away from the hatch and correspond to the battery boxes.

[0009] As a further improvement, a pair of openable hatch doors are rotatably arranged on the main box body, the two hatch doors are arranged on the left and right sides of the main box body respectively, and the industrial air conditioner is embedded on any one of the two hatch doors or both of the two hatch doors.

[0010] As a further improvement, a power supply control system is further arranged, the power supply control system comprises a battery management system master control arranged in the high-voltage box, and a plurality of battery management system slave controls are arranged in the battery boxes, wherein the battery management system master control is in communication connection with the battery management system slave controls.

[0011] As a further improvement, a DC-DC converter is further arranged above the high-voltage box in the control cabin.

[0012] The utility model discloses the beneficial effect lies in:

[0013] In the energy storage box, a temperature control system is added, in addition to the louver heat dissipation opening formed on the hatch and the control cabin to form ventilation and heat dissipation, an industrial air conditioner is arranged on the hatch, and the outdoor fan in the industrial air conditioner absorbs external air, which is cooled by the compressor, and then the indoor fan directs the air to the area where the battery box is located to form cooling. Moreover, since the low-temperature air is sent into the cabinet, the hot air can be quickly discharged from the cabinet, ensuring that the high-voltage energy storage box still has good heat dissipation performance when applied to the construction site. At the same time, there is no need to build a special power distribution room to store the high-voltage energy storage box to meet the heat dissipation of the energy storage box. This also makes the use of the energy storage box more flexible and more suitable for use in construction sites. The number of energy storage boxes can be determined according to the construction site, office location, construction project and other factors. BRIEF DESCRIPTION OF DRAWINGS
