BATTERY PACK LID FOR PROVIDING NON-CONTACT CHARGE INTERFACE AND PORTABLE TELEPHONE HAVING SAME

摘要

PROBLEM TO BE SOLVED: To provide a battery pack interface capable of charging a portable telephone having a battery pack only by placing the portable telephone onto a power transfer device.

SOLUTION: The battery pack lid 2 incorporates a power transfer interface 8 and a rectifying circuit 7, and transfers power to the portable telephone 1 having the battery pack 3 in which a protection circuit 5 and a secondary battery 4 are stored and a charge control circuit 6 via contact terminals 9, 10, thus easily providing an interface for non-contact power transfer in the same manner as the installation of a conventional battery pack lid.
