Description

Technical Field

[0001] The utility model belongs to the technical field of energy storage boxes, and more specifically, relates to a wall-mounted energy storage battery shell with no screws on the outside. Background Art

[0002] The wall-mounted energy storage battery box receives electricity from solar photovoltaic panels, wind turbines or other renewable energy devices, and then stores this electricity in the internal battery, which can be a lead-acid battery, a lithium-ion battery or other types of high-capacity batteries. The wall-mounted energy storage battery box is designed to charge and discharge at high efficiency. Its intelligent power management system ensures that the maximum capacity of the battery is not exceeded during charging to prevent the battery from overheating or damage. At the same time, when discharging, the system will also adjust the power output according to demand to avoid power waste. The wall-mounted energy storage battery box can provide electricity when needed, such as at night or on cloudy days, when solar photovoltaic panels or wind turbines cannot generate enough electricity. It can power household devices and also feed back electricity to the grid.

[0003] However, despite the significant progress in the functions and technologies of wall-mounted energy storage battery boxes, there are still some problems. Traditional designs often need to consider waterproof and dustproof performance (such as IP67 rating). The appearance of wall-mounted energy storage battery boxes inevitably adds many screws, handles, wall-mounted brackets and other undesirable factors that affect the appearance, which greatly reduces the aesthetics of the appearance. This problem is common in the energy storage industry. The industry's solutions to this problem are always not comprehensive. The ordinary solution cannot achieve waterproof and dustproof, and the appearance has no screws and no obvious handle position. If the mold opening solution is adopted, although it can achieve waterproof and dustproof, the cost is not only too high, but the problem of handle position still exists.

[0004] To this end, the utility model provides a wall-mounted energy storage battery with a screw-free outer shell. Utility Model Content
