PROBLEM TO BE SOLVED: To provide a charger connecting system by which the occurrence of the short circuit of a charging terminal can be prevented, and in which the voltage detection by the charger is constituted without increasing the number of the charging terminals. SOLUTION: A diode 5 is connected to battery power supply equipment 1 so that the charging direction between a secondary battery 3 and a positive pole charging terminal 11 becomes the forward direction. A discharge current from the secondary battery 3 is blocked during the short circuit. The energization of a charging current by an FET 15 is intercepted for a very short period of time at required intervals by a charging control circuit 16 when the charging is executed by connecting to the charger 2 after connecting a resistor 4 in parallel with the diode 5. The voltage of the secondary battery 3 is measured by a voltage detecting circuit 14 via the resistor 4 during the interception of the energization. COPYRIGHT: (C)2005,JPO&NCIPI
