The invention relates to a method for echelon utilization of a whole retired battery pack and a microgrid energy storage system. The method for echelon utilization of the whole retired battery pack comprises the steps of micro-grid energy storage system building, power-on control and power-off control. The micro-grid energy storage system is built and controlled according to a whole retired battery echelon utilization method. According to the invention, the microgrid energy storage system is established by echelon utilization of the whole retired battery pack, so that reuse of the retired battery is realized. 本发明涉及一种退役电池整包梯次利用的方法及微网储能系统。退役电池整包梯次利用的方法包括步骤：搭建微网储能系统步骤、上电控制步骤以及下电控制步骤。微网储能系统根据退役电池整包梯次利用的方法进行搭建及控制。本发明通过通过对退役电池整包梯次利用的搭建微网储能系统，实现了对退役电池进行再利用。
