With the development of renewable energy technology and the enhancement of environmental awareness, home energy management systems have gradually become an important part of modern life. As an efficient and convenient energy storage solution, wall-mounted lithium batteries can effectively store and manage household power resources, improve energy efficiency, and reduce electricity costs. In this paper, we will introduce the working principle, main functions, application scenarios, advantages of wall-mounted lithium batteries and their important role in home energy management.

Overview of wall-mounted lithium batteries
Wall-mounted lithium battery is a kind of energy storage equipment installed on the wall, using lithium-ion batteries as the energy storage medium, with high energy density, long life, lightweight and easy to install and other advantages. This equipment can be combined with solar photovoltaic system, wind power generation system and other renewable energy equipment to realize the storage and management of household power, providing users with stable and reliable power supply.
Working Principle
The working principle of wall-mounted lithium battery for energy storage is based on the charging and discharging process of lithium-ion battery, and its basic workflow is as follows:
1. Charging process:
-When the power generated by the household photovoltaic system or wind power system exceeds the household electricity demand, the excess power will be converted to DC power through the inverter and stored in the lithium battery.
-Lithium ions inside the storage battery move from the positive electrode to the negative electrode and are stored in the negative electrode material to complete the charging process.
2. Discharge process:
-When the demand for household electricity increases or when there is insufficient photovoltaic or wind power generation, the energy storage battery starts to discharge, converting the stored DC power into AC power through the inverter to supply household electricity.
