It is an objective of the present invention to provide an interface arrangement between a battery element ( 302 ) and an electronic device ( 301 ), e.g. a mobile phone, for reliable battery identification and for removal detection. The objectives of the invention are achieved with a combined analogue and digital interface between a battery element ( 302 ) and an electronic device ( 301 ) so that both analogue and digital data can be transferred from a battery element to an electrical device. Reliable digital authentication is used for determining if a battery element connected to an electronic device represents new battery technology. An analogue signalling scheme is used for identifying different battery elements representing older-generation battery technologies and for detecting battery removals. Digital data read from the battery element ( 302 ) may contain, for example, information for charging control, a discharge curve, and a serial number of the battery element.
