Energy storage system integration consists of 5 major modules: battery, PCS (inverter), BMS (battery management system), EMS (energy management system), and other electrical equipment. The battery is the core of the energy storage system. The function is the storage power, which determines the storage capacity of the energy storage system; BMS is the operating state of monitoring, evaluating management, and protecting the battery. Generally, it is integrated with the battery. When charging, turn the communication to DC. When discharge, the battery DC is converted into communication and supply load. And make necessary decisions. With the development of centralized landscape stations and energy storage to a larger capacity, DC high voltage has become the main technical solution for cost reduction and efficiency. The energy storage system of the DC -side voltage to 1500V has gradually become a trend. Compared with the traditional 1000V system, the 1500V system has increased the resistance of cable, BMS hardware module, PCS and other components from 1000V to no more than 1500V. The distributed scheme is also called the communication side multi -branch parallel. In contrast to the centralized technical solution, the distributed scheme transforms the DC side of the battery cluster and connects the distributed group inverter to the communication side parallel to avoid the risk of dynamic side parallel, capacity loss, DC arc risk, and increase operation. Safety. At the same time, the control accuracy changes from multiple battery clusters to a single battery cluster, and the control efficiency is higher. Some customers consult the price of energy storage battery cabinet containers. Today, Haileienergy will introduce the price of energy storage battery cabinet container prices for everyone.
