Abstract
A power supply device for a vehicle includes a battery (B) which serves as a first power storage device, a battery (B) which serves as a second power storage device, a vehicle load, a selection switch (RY) which selects one of the first and second power storage devices and connects the selected power storage device to the vehicle load, and a control device () which, when a current flowing through the selection switch (RY) is larger than a prescribed value, controls the vehicle load so that the current flowing through the selection switch (RY) is made smaller than the prescribed value, and switches the selection switch. Preferably, when the control device () switches the selection switch (RY), the control device controls inverters () to achieve a balance between electric power generated in a first motor generator (MG) and electric power consumed in a second motor generator (MG).
