Title:
SCREENING METHOD AND APPARATUS FOR CASCADE UTILIZATION OF BATTERY
Document Type and Number:
WIPO Patent Application WO/2023/071421
Kind Code:
A1
Abstract:
A screening method and apparatus for cascade utilization of a battery. The method comprises: acquiring a first initial voltage and first voltage change data of a standard battery in the same batch as a battery under test; acquiring first voltage difference data; obtaining, according to the first initial voltage, the first voltage difference data and an allowable cascade utilization deviation, an allowable cascade utilization voltage difference range corresponding to the first initial voltage; and acquiring a second initial voltage and second voltage change data of said battery, acquiring second voltage difference data, and when the second initial voltage and the first initial voltage are the same, determining whether the second voltage difference data falls within the allowable cascade utilization voltage difference range, and if the second voltage difference data falls within the allowable cascade utilization range, determining that said battery is up to standard. Whether a battery under test meets a cascade utilization standard can be determined more quickly and accurately by means of comparing second voltage data with an allowable cascade utilization voltage difference range, thereby reducing the screening time.
