Abstract

The invention provides a monitor method and device for a decommissioned battery. The method comprises steps of: acquiring state data of multiple battery modules in an energy storage unit collected bya battery management system (BMS), wherein the BMS is connected with the multiple battery modules separately; determining states of the multiple battery modules according to the state data; and separately displaying states of the multiple battery modules in a display screen, wherein the states are used for indicating that the multiple battery modules are normal or aged. In related technologies, asingle battery module affecting overall effect of the energy storage unit cannot be identified due to direct monitoring of the whole energy storage unit. The method solves the above problem. In the method, a single battery module in the energy storage unit is monitored separately, so that the single battery module affecting overall effect of the energy storage unit can be identified and controlledseparately.

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...
