Lithium battery energy storage system is a system that uses lithium-ion batteries as energy storage media, used for storing and releasing electrical energy. It is composed of lithium battery, equipped with Battery management system (BMS), corresponding power converter and other components. Lithium battery energy storage systems have many advantages, such as high energy density, long lifespan, high efficiency, and lower maintenance costs. They are widely used in many fields, including home energy storage systems, commercial and industrial energy storage systems, power grid regulation, and backup power sources. Lithium battery energy storage systems play an important role in energy storage and renewable energy integration, promoting the utilization of sustainable energy and the stability of power systems.Charging: When the power supply is sufficient, electrical energy can be input into the lithium battery energy storage system through the power grid or renewable energy systems (such as solar or wind). Electric energy is converted from alternating current to direct current through a power converter and stored in a lithium battery. Storage: The storage phase is the core of a lithium battery energy storage system. Lithium ion batteries have high energy density and low self discharge rate, making them an ideal energy storage medium. The Battery management system (BMS) monitors and controls the voltage, current, temperature and other parameters of the battery pack to ensure the safety and performance of the battery. Release: When electrical energy supply is required, the lithium battery energy storage system can release the stored electrical energy. Through power converters, direct current energy is converted into alternating current, which can be used to supply loads or inject into the power grid. Lithium battery energy storage systems can quickly release electrical energy in a short period of time, meet peak load demands or respond to power outages.Q:What is the name of your company?
