The structure of energy storage power supply

　　1. Energy storage battery section

　　Energy storage batteries are the core part of energy storage power sources, usually using lithium-ion batteries, nickel hydrogen batteries, lead-acid batteries, and other energy storage media. Energy storage batteries are classified into various types based on different energy parameters such as voltage and capacity, such as 18650 batteries, ternary batteries, etc.

　　2. Charge and discharge control circuit section

　　Energy storage batteries need to be managed through charging and discharging control circuits, which are a very important part of the internal structure of energy storage power sources. It is responsible for monitoring the status of the battery and controlling the charging and discharging of the battery. During charging, the charging control circuit controls the charging rate by changing the current and voltage. During discharge, the discharge control circuit monitors the battery status, controls the output current and voltage stability of the battery, in order to maintain the safety and stability of the energy storage battery.

　　3. Protection circuit section

　　The main function of the protective circuit is to cut off the connection between the battery and the circuit in case of overcurrent, overvoltage, overheating, etc. of the energy storage battery, in order to avoid battery damage and safety accidents. The composition of the protective circuit is simple, but its protective effect is very important.

　　Overall, the working principle of energy storage power sources is to store electrical energy through batteries, and then output electrical energy through charging and discharging control circuits when needed. When the battery level inside the energy storage power supply drops to a certain extent, it needs to be charged through an external power source. Energy storage power sources have different charging methods and rates in applications based on different needs and scenarios.

　　Modern industrial production, transportation, and household life all require electricity, so energy storage power sources are widely used in various fields. For example, electric vehicles, hybrid vehicles, electric bicycles, etc. all require energy storage batteries as a source of energy. In addition, various scenarios such as security monitoring, power station energy storage, and solar energy storage require the use of energy storage power sources.
