Battery charging method and system based on lithium plating detection, and automobile and medium

A battery charging system based on lithium plating detection, comprising:

• a charging strategy table acquisition module, configured to acquire a battery charging strategy table after receiving a battery charging instruction, wherein the battery charging strategy table is created based on a fast charging strategy formulated by a factory when the battery leaves the factory;
• the battery charging strategy table contains data related to battery charging including a charging current and a charging voltage;
• and the charging current in the battery charging strategy table is updated and adjusted depending on whether a lithium plating phenomenon occurs to the battery during charging and upon completion of charging of the battery;
• a charging lithium plating detection module, configured to charge the battery according to the charging current in the battery charging strategy table, and perform at least one charging lithium plating detection on the battery during the charging of the battery, to obtain a first lithium plating detection result;
• a first charging module, configured to:
• continue the charging of the battery according to the charging current and the charging lithium plating detection of the battery during the charging of the battery when the first lithium plating detection result is that no lithium plating phenomenon occurs, and stop the charging lithium plating detection of the battery when the first lithium plating detection result is that the lithium plating phenomenon occurs or the charging of the battery is completed;
• and
• a second charging module, configured to update the charging current in the battery charging strategy table according to a preset first current reduction strategy when the first lithium plating detection result is that the lithium plating phenomenon occurs, and continue the charging of the battery according to the updated charging current until the charging of the battery is completed.

A non-transitory computer-readable storage medium storing computer-executable instructions for, when executed by one or more processors, performing a battery charging method based on lithium plating detection, the method comprising:
