BATTERY CHARGING STRATEGY RELIABILITY TEST METHOD AND APPARATUS, TERMINAL AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/231736
Kind Code:
A1
Abstract:
A battery charging strategy reliability test method and apparatus, a terminal and a storage medium, relating to the technical field of new energy battery management. The method comprises: in response to a battery charging strategy initial reliability test instruction, obtaining initial test data to determine whether a design requirement is satisfied (101); if yes, in response to a battery charging strategy short-term reliability test instruction, obtaining short-term reliability test data to determine whether a design requirement is satisfied (102); and if yes, in response to a battery charging strategy long-term reliability test instruction, obtaining long-term reliability test data to determine whether a design requirement is satisfied (103). The reliability of a battery strategy is tested in dimensions such as negative electrode potential, temperature, expansion force, and cycle life by means of an initial reliability test, a short-term reliability test and a long-term reliability test in sequence, the design elements of the charging strategy are adjusted on the basis of a battery cell limit lithium plating-free charging database, the reliability tests are repeated until the design requirements are satisfied, thereby guaranteeing the safety and service life of a battery.
