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

Examples of the present application provide a charging method for a secondary battery, a charging apparatus for a secondary battery, a charging device, and a computer storage medium. The method includes: acquiring a first state of health SOH of the secondary battery when the secondary battery is at a preset charging node; activating the lithium-supplementing material when the SOH is less than or equal to a first threshold, to supplement lithium for the secondary battery; performing a first charging process on the secondary battery; determining a second state of health SOH of the secondary battery based on a working parameter of the secondary battery in the first charging process; and charging the secondary battery when the SOH is greater than a second threshold.
