Japanese Patent JP7003803
Kind Code:
B2
Abstract:
To provide a vehicle power supply capable of preventing discharge of a capacitor installed on a connection path between a power supply inside a vehicle and a charging port of a DC power supply.SOLUTION: The vehicle power supply includes: a quick charging port 9 to which a DC power supply 10 is connected; capacitors 31, 32, 33, connected between a positive electrode and a negative electrode of the quick charging port 9; an electrical load 4 connected to a battery 51; a first switch 11 for opening and closing a connection path between a positive electrode of the quick charging port 9 and the capacitors 31, 32, 33; a second switch 12 for opening and closing a connection path between a negative electrode of the quick charging port 9 and the capacitors 31, 32, 33; a first diode 21 for passing a current in a direction from the positive electrode of the quick charging port 9 toward the capacitors 31, 32, 33; and a second diode 22 for passing a current from the capacitors 31, 32, 33 toward the negative electrode of the quick charging port 9. The first diode 21 is connected in parallel with the first switch 11. The second diode 22 is connected in parallel with the second switch 12.SELECTED DRAWING: Figure 2
