Abstract

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