1. A power supply system comprising:
a first power circuit including a first electrical storage device;
a second power circuit including a second electrical storage device having a smaller heat capacity or a higher output-weight density and a lower energy-weight density than the first electrical storage device;
a voltage converter that converts a voltage between the first power circuit and the second power circuit;
a power converter that converts power between the first power and a rotary electrical machine;
a power controller that controls charging and discharging of the first and second electrical storage devices by operating the voltage converter and the power converter;
a first cooler that cools the first electrical storage device; and
a first cooling output controller that controls a first cooling output of the first cooler,
the power controller being configured to:
after a start of operation, execute a power pass control under which power is transferred between the first electrical storage device and the second electrical storage device, until a first condition regarding power output performance of both or either of the first electrical storage device and the second electrical storage device is satisfied, and
subsequent to the power pass control, execute a second priority control under which the second electrical storage device is discharged in preference to the first electrical storage device, until a second condition regarding power output performance of both or either of the first electrical storage device and the second electrical storage device is satisfied,
wherein the first cooling output controller makes the first cooling output smaller until the second condition is satisfied, as compared with after the second condition is satisfied.
