Abstract (en)

[origin: WO2011039035A2] The invention relates to a device for charging a battery, comprising a transistor through which a charging current flows from a voltage source into the battery connected to the device, and which has a control input to which a current source is connected, said current source adjusting the control current for the transistor such that the transistor switches off when the battery reaches a pre-determined maximum charge voltage, and thereby interrupts the charging current flow. The current source adjusts the control current of the transistor during the charging such that the transistor is operated beyond its saturation.
