Abstract
Provided is current detection apparatus for detecting current flowing through a power supply path of a power supply control apparatus. The power supply path includes a first conductor and a second conductor. The current detection apparatus includes: a first and a second shunt resistor connected in parallel between the first and the second conductor, and a current detection circuit detecting: (1) current flowing through the first shunt resistor; and (2) current flowing from the first to the second conductor via both the first and second shunt resistors. The current detection apparatus further includes an arithmetic circuit that calculates current flowing through the power supply path based on a correlative relationship between the current flowing from the first to the second conductor via both the first and the second shunt resistor and current flowing through the first shunt resistor, and the current detected by the current detection circuit.
