<P>PROBLEM TO BE SOLVED: To provide a charge system, an electronic apparatus, and a charge device which determine the deterioration level of a capacitor with high accuracy. <P>SOLUTION: A charge system includes: an electronic apparatus (radiation image capturing apparatus 1) incorporating a chargeable built-in power source 24; a charge control circuit 81 controlling charging to the built-in power source 24; a voltage detection circuit 82 detecting a voltage of the built-in power source 24; a determination part (body control part 22a) determining the deterioration level of the built-in power source 24; and a charge device (cradle 60) supplying electric power to the built-in power source 24 through the charge control circuit 81. The determination part obtains a voltage build-up rate of the built-in power source 24 based on the detection result of the voltage detection circuit 82 during the constant current charging conducted by the charge control circuit 81, sets a predetermined threshold value according to the voltage of the built-in power source 24 detected by the voltage detection circuit 82, and determines the deterioration level of the built-in power source 24 by comparing the obtained voltage build-up rate of the built-in power source 24 with the set predetermined threshold value. <P>COPYRIGHT: (C)2012,JPO&INPIT |
