The invention discloses a battery echelon utilization energy storage system and a reconfigurable device and architecture thereof. The reconfigurable device comprises an energy network card backboard,the energy network card backboard is arranged corresponding to a plurality of battery modules, and the energy network card backboard is used for independently accessing or bypassing each battery module in the plurality of battery modules; an energy concentrator is used for carrying out parameter detection on each battery module so as to obtain state data of each battery module; and an energy exchanger is in communication connection with the energy concentrator, and the energy exchanger is used for generating a reconfigurable control instruction according to the state data of each battery module and sending the reconfigurable control instruction to the energy concentrator so as to control the energy network card backboard through the energy concentrator. Therefore, by performing access or bypass switching on the plurality of battery modules, dynamic reconstruction is performed on the energy network topology of the plurality of battery modules so as to realize structural compatibility and electrical compatibility among the battery modules.
Description
technical field [0001] The present invention relates to the technical field of battery management, in particular to a reconfigurable device for a battery cascade utilization energy storage system, an elevator cascade utilization energy storage system, and a reconfigurable architecture for a battery cascade utilization energy storage system. Background technique [0002] In recent years, with the rapid development of the electric vehicle industry and the sharp increase in the number of electric vehicles, a large number of power lithium batteries have been put into use. As the design life of battery modules gradually expires, the problem of how to reuse decommissioned batteries has gradually emerged. [0003] In the actual energy storage system, the battery system is composed of a large number of battery cells / groups connected in series and parallel, and the batteries are generally mechanically connected by large-diameter DC cables or current-carrying copper bars. Although th...
