[0002] Wall-mounted lithium-ion batteries are energy storage devices that can be hung on a wall. They are primarily composed of lithium-ion battery cells enclosed in a compact, easy-to-install housing. When external power supply is insufficient, such as at night or during a power outage, the energy storage system converts the direct current (DC) from the lithium-ion battery cells into alternating current (AC) through an inverter and supplies it to the home grid, powering electrical appliances.
[0003] When installing low-voltage complete sets of equipment, wall-mounted batteries are fixedly installed on the wall. It is often necessary to pass the cables of the low-voltage complete sets of equipment through the wall. Currently, when passing the cables through the wall, it is necessary to pre-drill holes in the wall surface and install a protective tube in the hole. Then the cable is passed through the protective tube. However, due to the soft texture of the cable, it is not easy to pass through the protective tube. In addition, the positions of the cables change during the passage, and they are easily tangled together, affecting quick docking. For this reason, we propose a quick connector for energy storage cables. Summary of the Invention
