A cell supervising circuit includes: a measurement circuit which measures a state of charge of a secondary battery cell; a transformer which is provided for the measurement circuit to contactlessly receive power supply from a power source different from the secondary battery cell; and a communication circuit which transmits, via the transformer to a BMU which manages a status of a battery pack, the state of charge measured by the measurement circuit.
