Document Type and Number:
WIPO Patent Application WO/2022/063236
Kind Code:
A1
Abstract:
Provided are a battery charging method and system based on lithium plating detection, and an automobile and a medium, which relate to the technical field of battery charging. The method comprises: after a battery charging instruction is received, acquiring a battery charging policy table (S10); charging a battery according to a charging current in the battery charging policy table, and performing at least one instance of charging lithium plating detection on the battery during a battery charging process, so as to obtain a first lithium plating detection result (S20); when the first lithium plating detection result is that a lithium plating phenomenon does not occur, continuing charging the battery according to the charging current, and continuing to perform charging lithium plating detection on the battery, until the first lithium plating detection result is that a lithium plating phenomenon occurs, or, until charging of the battery is completed, and stopping performing charging lithium plating detection (S30); and when the first lithium plating detection result is that a lithium plating phenomenon occurs, updating the charging current in the battery charging policy table according to a preset first current reduction policy, and also continuing charging the battery according to an updated charging current, until the charging is completed (S40).
