The invention provides an energy storage system, method and device for a decommissioned battery pack, and relates to the field of recycling of the decommissioned battery pack. The energy storage system comprises a plurality of battery systems, a controller and an energy storage converter system, each battery system comprises a plurality of groups of battery packs which are connected in parallel; the controller comprises a first controller, a second controller and a third controller which are connected in an echelon manner; the energy storage converter system is connected in parallel with the plurality of second controllers; wherein the output end of the energy storage converter system is further connected with a power grid, and discharging operation and / or charging operation are / is carried out. According to the invention, energy storage control is realized based on the undisassembled battery pack, and the state of the battery management system in the decommissioned battery pack and the added controller are utilized to realize discharging and / or charging operation on the multiple groups of parallel battery packs, so that energy storage control is realized, and the energy storage efficiency is improved.
Description
technical field [0001] The invention relates to the field of recycling of decommissioned battery packs, in particular to an energy storage system, method and device for decommissioned battery packs. Background technique [0002] Due to the development of new energy vehicles, a large number of decommissioned lithium batteries have entered the market. If these decommissioned batteries cannot be properly used or disposed of, it will cause serious safety risks and environmental pollution. For example, reusing decommissioned batteries after screening In the field of electrochemical energy storage, it is used in scenarios such as peak shaving and valley filling, and backup power. It can not only solve the social problems caused by decommissioned batteries, but also bring benefits to enterprises and maximize the use of batteries. On the other hand, the energy storage in the current industry is basically based on the reorganization of new modules or new batteries, and almost no larg...
