[0002] In recent years, smart grids, renewable energy, and distributed energy have increased the demand for energy storage technology, and people have begun to pay attention to the research of large-capacity energy storage technology. Home energy storage equipment is usually divided into generator sets independent of normal power supply, special power supply lines in the power supply network that are effectively independent of normal power supply, and batteries.

[0003] As the application of home energy storage systems becomes more and more widespread, more and more energy storage systems are put into operation. However, most of the home energy storage systems on the market are currently made of stacked batteries, which cannot achieve the effect of plug-and-play, capacity expansion and efficiency improvement. Summary of the invention

[0004] In view of the above existing technical problems, the utility model provides a household energy storage battery that supports hot plugging, supports hot plugging, is plug-and-play, and is easy to expand.

[0012] The beneficial effect of adopting the above technical solution is that the bracket of the utility model holds the battery by a dial button, forming an independent sub-battery system as a whole. The dial button is linked with a light touch button. When the dial button is pushed open, a signal is given to the system through the light touch button, informing the system that the battery connected to the bracket is to be taken out. The system will shut down the battery through the control circuit, and the hot plug action can be realized. After pushing the battery to the bottom, push the dial button back, and the light touch button at the dial button will give the system a signal, informing the system that the battery connected to the bracket is ready and can be turned on. The system will turn on the battery and connect it to the system through the control circuit, and the hot plug action can be realized. The battery system of the utility model supports hot plugging and is easy to expand. When in use, one of the batteries can be directly unplugged with power and go out for fun; when you come back, plug it directly into the original system and use it normally. The sub-battery systems are connected to each other through the bracket plug-in terminals, which can be connected in parallel or in series, realizing multiple uses of one machine.
