    Abstract: A deterioration diagnosis apparatus of a battery includes one or more processors. The one or more processors are configured to execute discharging of each of a plurality of cells included in an assembled battery while measuring a voltage of each of the cells, estimate a deterioration degree of each of the cells using voltage data indicating a transition of the voltage of each of the cells from a discharging start voltage to a predetermined discharging end voltage, and end the discharging when voltages of all the cells included in the assembled battery reach the predetermined discharging end voltage. The predetermined discharging end voltage is a cell voltage at which a change degree of the cell voltage per unit discharging amount starts to sharply rise while the cell voltage is dropping due to the discharging.

    Abstract: A rotor core heating device (100) is configured to heat an inner peripheral side surface and an outer peripheral side surface of a rotor core (150) through induction heating. The rotor core has a hollow cylindrical shape. The rotor core heating device includes a first coil (110), a second coil (120) and a magnetic flux shielding jig (170). The first coil is disposed inside the rotor core and is configured to heat the inner peripheral side surface of the rotor core through induction heating. The second coil is disposed outside the rotor core and is configured to heat the outer peripheral side surface of the rotor core through induction heating. The magnetic flux shielding jig has a hollow cylindrical shape and is disposed opposite a first end surface of the rotor core with a gap provided between the first end surface and the magnetic flux shielding jig in an axial direction of the rotor core.
