RECHARGEABLE ELECTRIC APPARATUS
DRIVE
July 31, 2013
A rechargeable electric apparatus includes a switching device (12), a first shunt resistor (13-1) that connects the switching device (12) and a positive electrode of a secondary battery (11), a second shunt resistor (13-2) that connects a load (14) and the positive electrode of the secondary battery (11), and a control unit (15). The control unit (15) controls turning on and off of the switching device (12) on the basis of voltages at two ends of the first shunt resistor (13-1) and voltages at two ends of the second shunt resistor (13-2) in order to control a supply current flowing to the secondary battery (11) via the first shunt resistor (13-1) and to control a load current flowing to the load (14) via the second shunt resistor (13-2).
