Document Type and Number:
WIPO Patent Application WO/2021/089057
Kind Code:
A1
Abstract:
A method, a system, and a device for acquiring battery health, and a readable storage medium. The acquisition method comprises: establishing an SOC table (10); acquiring battery information of a target charging battery (20); on the basis of the battery information and the SOC table, acquiring target SOC data corresponding to the target charging battery (30); acquiring current charging data of the target charging battery in a charging time period (40), the current charging data comprising a current charging input power amount and current SOC data in the charging time period; amending the current SOC data on the basis of the target SOC data; on the basis of the amended current charging data, calculating a current SOH of the target charging battery (60). In the present method, accurate SOC values are acquired for different models of batteries at different travel distances, and thus the SOC value during an actual charging process for any battery is amended and to obtain a more accurate battery SOH, so as to understand the condition of the degradation of the battery in a timely manner.
