CHARGING METHOD FOR SECONDARY BATTERY, CHARGING APPARATUS FOR SECONDARY BATTERY, CHARGING DEVICE, AND COMPUTER STORAGE MEDIUM

A charging method for a secondary battery including a lithium-supplementing material. The method includes acquiring a first state of health of the secondary battery in response to the secondary battery being at a preset charging node, activating the lithium-supplementing material in response to the first state of health being less than or equal to a first threshold to supplement lithium for the secondary battery, performing a charging process on the secondary battery, determining a second state of health of the secondary battery based on a working parameter of the secondary battery in the charging process, and charging the secondary battery in response to the second state of health being greater than a second threshold.
