Voltage detection system

A voltage detection system used for a fuel cell stack including a plurality of cells stacked on each other and divided into a plurality of groups, comprising:

• a plurality of cell voltage monitors configured to detect a voltage from one cell or two or more cells of the plurality of cells as a unit;
• and
• a plurality of electronic elements each having a resistive component with a respective different resistance value, wherein
• each of the plurality of electronic elements is connected to a corresponding cell voltage monitor of the plurality of cell voltage monitors,
• each of the plurality of cell voltage monitors is associated with a respective one of the plurality of groups,
• each of the plurality of cell voltage monitors includes:
• a memory storing inspection information that represents predetermined association between a physical quantity correlated to the resistance value and a corresponding inspection logic of a plurality of inspection logics used for detecting the voltage;
• an acquirer configured to acquire the physical quantity of the electronic element of the plurality of electronic elements connected to the cell voltage monitor itself;
• and
• a detector configured to detect the voltage from a corresponding cell of the plurality of cells under a selected inspection logic of the plurality of inspection logics, wherein the detector selects the inspection logic to be used from the plurality of inspection logics using the acquired physical quantity and the inspection information.
