Claim 0:
1. 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 second cell of the second battery cells in a first direction, and
the first cell 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;

a first switch configured to switch between a conducting path where the first battery stack 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; and
a second switch configured to 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.
