Abstract

PURPOSE:To confirm charging of a battery easily, by measuring and indicating time integration of charging current. CONSTITUTION:A low resistor R having scarce influence on a current loop is inserted between a DC constant voltage source 1 and a battery to be charged, then the voltage across the resistor R is converted through a voltage/frequency converter 4 into frequency which is counted through a pulse counter 5 and indicated on an indicator 6. Since integrated charging current is indicated, charging amount of battery can be confirmed accurately.
