A power supply system capable of reducing loss during external charging and a vehicle including the same are provided. RLY22, 28 and SMR30 are turned on when voltage V of external power supply 50 detected by voltage sensor 42 is higher than threshold value Vth during external charging of power storage devices 10, 12 by external power supply 50. , RLY 24, 26 are turned off. Thereby, power storage devices 10 and 12 are connected in series between positive electrode line PL2 and negative electrode line NL2. When voltage V is equal to or lower than threshold value Vth during external charging, RLY 22, 24, 26, and 28 are turned on, and SMR 30 is turned off. Thereby, power storage devices 10 and 12 are connected in parallel to positive electrode line PL2 and negative electrode line NL2. [Selection] Figure 1 |
