PROBLEM TO BE SOLVED: To provide a power storage system capable of charging a power storage device by using a DC power source and an AC power source.SOLUTION: A positive electrode line PL and a negative electrode line NL have respectively a system main relay SMR. A first charging line DCL having a first charging relay DCR supplies DC power outputted from a DC power source 33 to a power storage device 10. The first charging line DCL is coupled to the positive electrode line PL and the negative electrode line NL respectively between the motor generator 22 and the system main relay SMR. A second charging line CHL having a second charging relay CHR supplies DC power to the power storage device 10 in a state that AC power outputted from an AC power source 44 is converted into DC power. The second charging line CHL is coupled to the positive electrode line PL and the negative electrode line NL respectively between the power storage device 10 and the system main relay SMR. |
