Abstract

Under a condition that a command to stop a fuel cell system is received and a state of charge of a secondary battery is equal to or lower than a threshold which is a value obtained by adding a first predetermined value to a lower limit at which electric power required to stop and start the fuel cell system is supplied, forced charging of the secondary battery by a fuel cell is performed until the state of charge reaches the threshold. After the forced charging is performed, in a case where the command to stop the fuel cell system is received within a predetermined period, the controller sets the threshold to a value obtained by adding a second predetermined value lower than the first predetermined value to the lower limit under the condition.
