Ⅱ. Working Principle

The working principle of the wall-mounted energy storage lithium battery is based on the charging and discharging process of the lithium-ion battery. Its basic working process is as follows:

1. Charging process:

When the power generated by the home photovoltaic system or wind power generation system exceeds the household electricity demand, the excess power will be converted into direct current through the inverter and stored in the lithium battery.

The lithium ions inside the energy 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. Discharging process:

When the household electricity demand increases or the photovoltaic or wind power generation is insufficient, the energy storage battery begins to discharge, and the stored direct current is converted into alternating current through the inverter to supply household electricity.

The lithium ions inside the energy storage battery move from the negative electrode back to the positive electrode, releasing electrical energy to complete the discharge process.
