ABSTRACT:
The invention relates to a battery pack having a dual-type smart card interface. In one embodiment, a battery pack is connectable to a mobile communication terminal having at least one contact for a power supply and at least one contact for communication with the mobile communication terminal. The battery pack comprises a battery cell, an RF antenna, a slide-type connector, a contact-type connector coupled to the RF antenna, a plurality of battery pack contacts, which are coupled to the mobile communication terminal electrically, for supplying power to the mobile communication terminal and for communication with the mobile communication terminal, an SCR, which is coupled to the slide-type connector and the contact-type connector respectively, for reading data stored on a smart card that is coupled to either the slide-type connector or the contact-type connector and for writing data received from the mobile communication terminal on the smart card, and a battery protection circuit, which is located between the battery cell and the plurality of battery pack contacts, for protecting the battery cell from an instantaneous power surge.
