Abstract

A control device for controlling charging of a rechargeable battery, the control device being configured to: determine the voltage of the battery during charging of the battery, stop charging, when the determined voltage exceeds a predetermined upper voltage limit, determine the voltage of the battery after stopping charging, determine the voltage difference between the predetermined upper voltage limit and the determined voltage of the battery after stopping charging, and continue charging, when the determined voltage difference exceeds a predetermined threshold. A corresponding method controls charging of a rechargeable battery.
