An electric current detection apparatus has a single magnetic sensor for detecting a first current which flows from a battery and also a second current which flows into or from the battery during different occasions from the first current and is substantially smaller than the first current. The magnetic sensor has a magnetic core surrounding first and second conductors, with the second conductor carrying the second current and with the first conductor being shunted by a third conductor such as to conduct a predetermined proportion of the first current.
