Claim 13:
14. A method of a vehicular power supply device to be equipped in a vehicle, the vehicular power supply device comprising: an electric storage unit including a first battery stack including a plurality of first battery cells with a first internal resistance and a second battery stack including a plurality of second battery cells manufactured as recycled products, the second battery cells with a second internal resistance other than the first internal resistance, the second battery stack is arranged adjacent to the first battery stack in the electric storage unit,
wherein a first cell of the first battery cells is arranged adjacent to a third cell, other than the second cell, of the second battery cells in a second direction orthogonal to the first direction, an inverter configured to couple, via the inverter, the electric storage unit with a driving motor to drive the vehicle, a converter configured to couple, via the converter, the electric storage unit with an electric device group installed in the vehicle, the method comprising: switching a first switch between a conducting path where the first battery stack including the plurality of second battery cells manufactured as recycled products in the electric storage unit is coupled to the inverter and a conducting path where the first battery stack in the electric storage unit is coupled to the converter, the second battery stack is arranged adjacent to the first battery stack; and
switching a second switch between a conducting path where the second battery stack in the electric storage unit is coupled to the inverter and a conducting path where the second battery stack in the electric storage unit is coupled to the converter.
