Title: POWER SUPPLY SYSTEM AND BATTERY UNIT
Abstract:
A power supply system provided with only two of three paths among a path connecting a first connection point (N1) to which a first storage battery (11) is connected and a second connection point (N2) to which a second storage battery (12) is connected, a path connecting the first connection point and a third connection point (N3) to which a rotary electric machine (17) is connected, and a path connecting the second connection point and the third connection point, the two paths being provided respectively as a first path (L1) and a second path (L2). In addition, the power supply system is provided with: a first switch (21) for switching between electrically connecting and disconnecting the first path; a second switch (22) for electrically connecting and disconnecting the second path; and a booster circuit (24) that is connected in parallel with respect to the first switch or with respect to the first switch and the second switch, and that boosts and then outputs a voltage that is input from the first storage battery or the second storage battery.
