[0033] The following is combined with Figure 1 - Attachment Figure 6 , further details of this application are given.

[0034] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0035] The hidden interface balcony energy storage battery disclosed in this embodiment, refer to Figures 1 to 3 , including a shell 1 and an interface 2, the shell 1 is preferably made of metal, and a chamber for accommodating a battery and a wireless module is provided inside the shell 1, and the shell 1 is fixedly connected to the internal battery and the wireless module by screws; the side of the shell 1 is also concavely provided with an interface groove 11, referring to Figure 5 An interface hole 12 is penetrated on one side of the interface groove 11 near the top surface of the shell 1. The interface 2 is arranged in the interface groove 11 and is electrically connected to the balcony energy storage battery through the interface hole 12. The interface groove 11 can protect the interface 2 arranged therein, thereby preventing the interface 2 from being damaged by external force impact or rain immersion, thereby improving the reliability of the equipment. The recessed groove wall is in direct contact or heat radiation contact with the battery in the shell 1, which also improves the heat dissipation of the battery. At the same time, the hidden interface 2 also makes the balcony energy storage battery more concise and beautiful as a whole.

[0036] In this embodiment, two interface grooves 11 are provided, and the two interface grooves 11 are symmetrically arranged on two opposite sides of the shell 1. The user can also put his hand into the interface groove 11 to hold it. The interface groove 11 acts as a handle, and the two symmetrical interface grooves 11 are more convenient to hold with both hands and convenient to carry. The bottom of the interface groove 11 is inclined in the direction away from the interface 2 and connected to the side of the shell 1. The overall shape of the interface groove 11 is a triangular prism. If rainwater enters the interface groove 11, the rainwater will flow out along the inclined bottom of the groove and will not accumulate in the interface groove 11, thereby avoiding the interface 2 from being soaked by rainwater and causing damage. The shape, position and size of the interface groove 11 can be set according to actual conditions to meet the requirements of protecting the interface 2 and draining rainwater, and are not limited here.

[0037] In addition, the interface 2 is also inclined, and the interface 2 has the same inclination angle as the bottom of the interface slot 11, so that the interface 2 can be installed more snugly in the interface slot 11 and is easier to connect to external devices. Each interface slot 11 has four interfaces 2, with a total of eight interfaces 2. The interface 2 in the interface slot 11 on one side is two groups of MC4 input photovoltaic connections, which are used to connect solar photovoltaic panels, and the interface 2 in the interface slot 11 on the other side is two groups of MC4 output micro-inverters, which are used to convert direct current into alternating current (AC) and output to connected electrical equipment for home or commercial use; this embodiment adds a group of MC4 input photovoltaic connections and MC4 output micro-inverters, which can connect more solar photovoltaic panels and electrical equipment, and improve the applicability of the balcony energy storage battery.

[0038] Reference Figure 4 and Figure 5 The bottom of the housing 1 is fixedly connected with a heat sink 3, through which the heat generated in the energy storage battery can be dissipated, thereby reducing the operating temperature of the battery, preventing the battery from overheating and extending its service life; the heat sink 3 is usually made of a material with good thermal conductivity. The heat sink 3 in this embodiment is preferably an aluminum alloy heat sink 3. The aluminum alloy has good thermal conductivity, which makes the heat dissipation efficiency of the heat sink 3 higher, and also has the advantages of corrosion resistance, high strength and low cost. The heat sink 3 can also adopt other designs, such as a soaking plate type, a heat pipe type, etc., to effectively dissipate heat according to different application scenarios and needs. The heat sink 3 is set on the bottom surface to avoid direct touch and burns, thereby improving the safety of the balcony energy storage battery.

[0039] In order to improve the heat dissipation efficiency of the heat sink 3, refer to Figure 5 and Figure 6 In this embodiment, a padding block 4 is also provided on the bottom surface of the housing 1. There are four padding blocks 4, which are fixedly mounted on the four corners of the heat sink 3 respectively; the padding block 4 pads the balcony energy storage battery, avoids the heat sink 3 from directly contacting the ground, provides appropriate ventilation space for the heat sink 3, and thus improves the heat dissipation efficiency of the heat sink 3. The padding block 4 is preferably a rubber pad, which has good insulation properties, can effectively protect the battery, and can also play a role in anti-slip; it also has good buffering properties, which can reduce the vibration and impact of the balcony energy storage battery. An antenna signal hole 31 is opened on the heat sink 3, which exposes the antenna signal inside the housing 1, so that the signal of the antenna signal is better. The sunlight energy storage battery of this embodiment can wirelessly transmit the working status, power information and other relevant data of the balcony energy storage battery to the remote monitoring center or the user's mobile device through the antenna signal, so that the user can monitor and control the operation of the energy storage battery anytime and anywhere, and realize remote management and operation. Further, the antenna signal hole 31 is sealed with a film, which not only plays a waterproof role, but also does not affect the transmission of the signal.

A charging pack interface 5 for increasing the battery capacity is installed in the receiving groove 13. The charging pack interface 5 is arranged in the receiving groove 13 so that the charging pack interface 5 is not easily damaged by external force or bump. In other embodiments, a protective cover can be provided on the charging pack interface 5 to play a role of dustproof and waterproof, and can more effectively protect the charging pack interface 5. A power switch 6 is also provided in the middle of the top surface of the housing 1 to turn on or off the output of the power supply.

[0041] The working principle of this embodiment is: connect the balcony energy storage battery with solar photovoltaic panels and other equipment, and place it on the balcony for photovoltaic energy storage. The hidden interface 2 and heat sink 3 prevent rainwater from soaking. The user can connect the balcony energy storage battery through the antenna signal device to understand the working status of the equipment and operate it. When power is needed, just connect the power-consuming equipment through interface 2.

[0042] The present application designs the structure of the housing 1, places the interface 2 in the interface groove 11, and uses the inclined groove bottom design to make the interface 2 not easily impacted by external forces and not easily soaked by rainwater; at the same time, the heat sink 3 is also arranged at the bottom of the housing 1 to avoid direct sunlight and rainwater soaking, thereby improving the reliability of the device. In addition, the hidden interface 2 and heat sink 3 also make the balcony energy storage battery more concise and beautiful.
