Energy storage all-in-one machine, leading the green era

With the increasing severity of the global energy crisis and the increasing awareness of environmental protection, energy storage technology has become one of the important means to solve energy problems. The battery energy storage system is currently one of the most common and practical energy storage technologies. In the battery energy storage system, the battery PCS and BMS are the most basic components. Let's take a look at these three basic concepts.

         The battery is the core part of the battery energy storage system. It is a device that converts chemical energy into electrical energy. It consists of four parts: positive electrode, negative electrode, electrolyte and separator. There are many types of batteries, the common ones are lead-acid batteries, nickel metal hydride batteries, carp ion batteries and so on. Among them, carp-ion batteries have become the most commonly used battery type in current battery energy storage systems due to their high energy density, long life, and environmental protection. PCS is the core equipment in the battery energy storage system. It is a device that converts the electric energy stored in the battery into alternating current energy and supplies it to the grid or users. PCS is mainly composed of inverter, transformer, controller and so on. Its main function is to convert DC power into AC power, control the input and output of power, and ensure the safety and stability of the system. The performance of PCS directly affects the operating efficiency and service life of the battery energy storage system. BMS is the abbreviation of battery management system, which is an important part of battery energy storage system. BMS is mainly composed of monitoring module, control module, communication module and other parts. Its main function is to monitor and control the state of the battery in real time, including battery voltage, current, temperature, SOC and other parameters. At the same time, BMS can also protect and control the battery, such as overcharge, overdischarge, overcurrent, etc. to ensure the safety and life of the battery.

         To sum up, battery, PCS, and BMS are the three basic components of a battery energy storage system. As the core part, the battery is responsible for storing energy; PCS converts the electric energy stored in the battery into AC electric energy; BMS monitors and protects the battery in real time to ensure the safety and life of the battery. In the design and operation of the battery energy storage system, the coordination of the three is very important. Only in this way can the efficient, stable and safe operation of the battery energy storage system be realized.
