Abstract

The invention provides a method, device and electronic equipment for estimating the number of cycles from a battery to a diving point. The method includes: receiving a detection instruction, the detection instruction is used to indicate the estimated number of cycles of the battery to be tested from the diving point; The first capacity and the first discharge DC internal resistance in the charging stage; according to the first total charging capacity, the first capacity and the first discharge DC internal resistance, determine the cycle circle of the battery to be tested from the diving point Number; display the cycle number of the battery to be tested from the diving point. The method, device and electronic equipment for estimating the number of cycles between the battery and the diving point provided by the present invention can accurately estimate the number of cycles between the battery and the diving point, which is beneficial to the reasonable recycling of lithium batteries, thereby realizing resource maximization use.

Description

technical field [0001] The invention relates to the field of lithium ion batteries, in particular to a method, a device and an electronic device for estimating the cycle number of a battery from 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 State of Health (SOH) of the battery drops to 80%, it is no longer suitable for use in the field of power batteries, so consider the cascade utilization of retired batteries and turn to the second gradient for grids, new energy power generation, In the field of energy storage such as Uninterruptible Power System (UPS), the maximum utilization of resources can be achieved. However, batteries tend to decay to a diving point with subsequent use. The diving point...
