Abstract
The charging control apparatus according to the present disclosure includes a voltage sensor configured to detect the voltage of a battery cell and a controller configured to execute an intermittent charging process to alternately repeat a charging mode and a resting mode for the battery cell. Under the condition that the charging mode is switched to the resting mode while the intermittent charging process is being executed, the controller is configured to execute: an operation of determining an internal resistance of the battery cell based on an amount of change in voltage of the battery cell in a resting period where the resting mode continues; and an operation of recording the internal resistance in association with SOC of the battery cell.
