Beschreibung
Zusammenfassung:	The invention provides a micro-grid new energy hybrid energy storage system which comprises a new energy power generation subsystem, an energy storage carrier subsystem, a converter subsystem, a high/low-voltage power distribution subsystem and a background monitor subsystem. According to the invention, battery equalization is performed through a BMS (battery management system), a cask effect caused by non-uniformity of voltage, capacity and other parameters is avoided, and the phenomena that the capacity of the whole group is reduced and the service life of the battery is shortened due to vicious circle of performance of the battery pack are avoided. Meanwhile, a refrigeration mode of air-conditioning equipment is scientifically controlled through a heat management system, so that the battery keeps a proper, uniform and stable environment temperature in the operating process. Therefore, the service life of the storage battery is prolonged, and the operating cost is effectively reduced. A container modular en
