摘要： Disclosed is an electric current measurement apparatus to measure a current flowing in a wire. The electric current measurement apparatus comprises a first magnetic element; a second magnetic element; a first current source capable of supplying a first alternating current to the first magnetic element; a second current source capable of supplying a second alternating current to the second magnetic element, a phase of the second alternating current being deviated from a phase of the first alternating current; a first lowpass filter configured to pass a low frequency component of an output from the first magnetic element; and a second low pass filter configured to pass a low frequency component of an output from the second magnetic element. The electric current measurement apparatus also comprises an operator configured to calculate a square root of a sum of squares of an output from the first low pass filter and an output from the second low pass filter, and / or an arc tangent value of the output from the first low pass filter and the output from the second low pass filter.

摘要： The present invention provides a charge/discharge measuring apparatus capable of appropriate charge/discharge management by accurately measuring a capacitance change of a secondary battery in charge/discharge. This charge/discharge measuring apparatus is configured such that a current from the secondary battery can be switched between a first connection circuit in which the secondary battery, a load resistor, and a conductor film are connected in series and a second connection circuit in which the secondary battery, a charger, and the conductor film are connected in series. Moreover, this charge/discharge measuring apparatus has a magnetic film arranged in parallel with the conductor film and connected in parallel with connection from the secondary battery to the load resistor and the charger and has a voltage detecting means for detecting a voltage change in the magnetic film.
