Abstract

The invention provides a method and device for estimating the number of cycles of a battery away from a diving point and electronic equipment. The method comprises the steps: receiving a detection instruction, wherein the detection instruction is used for indicating and estimating the number of cycles of a to-be-detected battery away from the diving point; according to the detection instruction, respectively obtaining a first total charging capacity of the to-be-detected battery, a first capacity in a constant voltage charging stage and a first discharging direct current internal resistance; according to the first total charging capacity, the first capacity and the first discharging direct-current internal resistance, determining the number of cycles of the to-be-detected battery away fromthe diving point; and displaying the number of cycles of the to-be-detected battery away from the diving point. According to the invention, the method, device and the electronic equipment can accurately estimate the number of the number of cycles of the battery away from the diving point, facilitate the reasonable recycling of the lithium battery, and achieve the maximum utilization of resources.

Description

technical field [0001] The invention relates to the field of lithium-ion batteries, in particular to a method, device and electronic equipment for estimating the number of cycles from a battery to a diving point. Background technique [0002] With the development of science and technology, lithium-ion batteries (referred to as lithium batteries) have gradually become the first choice for electric vehicles due to their high energy density and long cycle life, and have been rapidly developed and applied. [0003] When the battery life state (State of Health, SOH) of the battery drops to 80%, it is no longer suitable for use in the field of power batteries, and the cascade utilization of decommissioned batteries is considered, turning to the second gradient for use in power grids, new energy power generation, non-use Uninterruptible Power System (UPS) and other energy storage fields to maximize the use of resources. However, the battery tends to decline to the diving point wit...
