Abstract:
The present disclosure is made in order to reduce inaccuracy of current sensors. A fuel cell system  100  comprises a converter  150  configured to convert output voltage of the fuel cell  1,  and a current sensor CS 1  including a preliminarily magnetized magnetic core MC 1  and configured to measure current flowing in the converter  150  from the fuel cell  1.  A controller  160  comprises, as driving modes of the fuel cell system  100,  a first driving mode DM 1  in which a maximum current value IL1max in a target circuit of current measurement by the current sensor CS 1  is lower than a current value for preliminary magnetization of the magnetic core and a second driving mode DM 2  in which the maximum current value IL2max in the target circuit is higher than the maximum current value IL1max in the target circuit in the first driving mode DM 1.  When an accumulated temperature value IT of the current sensor CS 1  in the first driving mode DM 1  has exceeded a threshold ITth, the second driving mode DM 2  is executed and subsequently the first driving mode DM 1  is executed.

Claim (Index 1):
A fuel cell system comprising:\n a fuel cell; a converter configured to convert output voltage of the fuel cell; a current sensor comprising a preliminarily magnetized magnetic core and configured to measure current flowing in the converter from the fuel cell; a temperature sensor configured to measure temperature of the current sensor; and a controller configured to control the fuel cell system, wherein the controller comprises: as driving modes of the fuel cell system, a first driving mode in which a maximum current value in a target circuit of current measurement by the current sensor is lower than a current value for preliminary magnetization of the magnetic core; and a second driving mode in which a maximum current value in the target circuit is higher than the maximum current value in the target circuit in the first driving mode, and wherein when an accumulated temperature value of the current sensor in the first driving mode has exceeded a threshold, the controller executes the second driving mode on a predetermined condition and subsequently the first driving mode.
