Abstract

The invention discloses a battery cycle performance accelerating and evaluating method. The battery cycle performance accelerating and evaluating method includes: step 1, charging a battery till the battery is fully charged; step 2, discharging the battery in real time; step 3, increasing the discharging voltage of the battery to a preset discharging voltage when a first preset charge state is reached during discharging, returning to the step 1 when the battery voltage is discharged to a second preset charge state, and repeating in cycles and looping for times preset by a user. By the aid of the battery cycle performance accelerating and evaluating method, the battery cycle performance can be conveniently and reliably evaluated, cycle time can be shortened, evaluation cost for the battery cycle performance is reduced, producing cost of the battery is lowered, market application prospect of products manufactured by battery manufacturers is benefited, and great production practical significance is provided.

Description

technical field

[0001] The invention relates to the technical field of batteries, in particular to a method for accelerating evaluation of battery cycle performance. Background technique

[0002] At present, lithium-ion batteries have the advantages of high specific energy, many cycle times, and long storage time. They are not only widely used in portable electronic devices such as mobile phones, digital cameras, and laptop computers, but also widely used in electric vehicles and electric bicycles. And large and medium-sized electric equipment such as electric tools.

[0003] For batteries, cycle performance is one of the important factors to evaluate the quality of batteries. Various batteries have different requirements for the number of cycles. Mobile phone batteries require 500 cycles at room temperature, leaving 80% of the capacity remaining. Some notebook batteries require 800 cycles, while power batteries require 2,000 to 3,000 cycles. It takes time to complete the ...
