PROBLEM TO BE SOLVED: To enable efficient and quick increase of temperature for a power storage device under a low-temperature state in a power supply system having a power storage device and a converter containing a reactor.SOLUTION: A converter 15 can selectively use reactors L1a and L1b through ON/OFF control of relays SMRB1 and SMRB2 by a control device 50. The reactor L1a is disposed as a component of the converter 15 separately from a main battery 10. On the other hand, the reactor L1b is arranged to have a heat transfer path between the reactor L1b and the main battery 10. Based on at least the output of a temperature sensor 16, the controller 50 turns off the relay SMRB1 and also turns on the relay SMRB2 under the low-temperature state of the main battery 10, whereby the reactor of the converter 15 is configured by the reactor L1b.SELECTED DRAWING: Figure 1 |
