CHARGE CONTROL METHOD, CHARGE CONTROL APPARATUS, AND BATTERY-MOUNTED EQUIPMENT

In general, according to one embodiment, a charge control method includes acquiring a measured temperature of a lithium ion battery, acquiring a threshold value for stopping charging of the lithium ion battery according to the measured temperature of the lithium ion battery based on a relationship between a cycle life and a charging capacity of the lithium ion battery for each temperature of the lithium ion battery, and, charging the lithium ion battery based on the threshold value.
