Abstract

The present invention provides a method and device for monitoring decommissioned batteries, wherein the method includes: acquiring state data of multiple battery modules in an energy storage unit collected by a battery management system (BMS), wherein the BMS is connected with the A plurality of battery modules are connected; the states of the plurality of battery modules are determined according to the state data; and the states of the plurality of battery modules are respectively displayed on the display screen, wherein the states are used to indicate the A battery module is normal or aging. The present invention can solve the problem in the related art that directly monitoring the entire energy storage unit leads to the inability to identify a single battery module that affects the overall effect of the energy storage unit. By monitoring a single battery module in the energy storage unit individually, A single battery module that affects the overall effect of the energy storage unit can be identified and controlled individually.

Description

technical field [0001] The invention relates to the field of batteries, in particular to a monitoring method and device for decommissioned batteries. Background technique [0002] Under the joint promotion of energy saving, emission reduction and green environmental protection, electric vehicles have received more and more attention as a new energy transportation tool. Lithium-ion batteries have gradually become the mainstream of electric vehicles due to their high specific energy and long life. However, when the capacity of the on-board power battery drops below 80%, it is no longer suitable for electric vehicles. If it is directly scrapped, it will cause a great waste of resources and even cause environmental pollution. At the same time, my country is entering the period of large-scale scrapping and recycling of power batteries, and it is imperative to reuse the retired batteries of electric vehicles. The decommissioned batteries of electric vehicles are tested and sorte...
