Title:
METHOD AND APPARATUS FOR ESTIMATING REMAINING CHARGING TIME, AND COMPUTER STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/082982
Kind Code:
A1
Abstract:
A method for estimating the remaining charging time. The method comprises: acquiring a real state parameter of a battery at the current moment and an output capability of a charging device for charging the battery (S110); obtaining the maximum allowable charging current of the battery at the current moment according to the real state parameter and a battery charging map, and obtaining an effective charging current of the battery at the current moment according to the maximum allowable charging current at the current moment and the output capability (S120); according to the effective charging current and the real state parameter at the current moment, obtaining estimated state parameters of the battery at subsequent moments by using a battery thermal simulation model (S130); and if it is determined that an estimated state parameter at a target moment represents that the charging of the battery has been completed, obtaining the remaining charging time according to the current moment and the target moment (S140).
