Title:
POWER SOURCE SYSTEM AND ELECTRIC VEHICLE
Document Type and Number:
WIPO Patent Application WO/2019/039263
Kind Code:
A1
Abstract:
A power source system 20 installed in a vehicle 10, wherein the power source system is provided with: high-voltage batteries 21A, 21B; a first motor 25A that receives a supply of power from the high-voltage batteries 21A, 21B and drives a front wheel 11A side of the vehicle 10; a first relay 22A that is disposed in a first power supply path 30A between the high-voltage batteries 21A, 21B and the first motor 25A, and turns conduction through the first power supply path 30A on/off; a second motor 25B that receives a supply of power from the high-voltage batteries 21A, 21B and drives a rear wheel 11B side of the vehicle 10; a second relay 22B that is disposed in a second power supply path 30B between the high-voltage batteries 21A, 21B and the first motor 25A, and turns conduction through the second power supply path 30B on/off; a detection unit 27 for detecting anomalies in the first power supply path 30A and in the second power supply path 30B; and a control unit 28 for controlling the on/off-states of the first relay 22A and the second relay 22B. The control unit 28 places the first relay 22A and the second relay 22B in the on-state and enables conduction in the first power supply path 30A and the second power supply path 30B if no anomaly in the first power supply path 30A or the second power supply path 30B has been detected by the detection unit 27, places the first relay 22A in the off-state and shuts off the conduction in the first power supply path 30A when an anomaly in the first power supply path 30A has been detected by the detection unit 27, and places the second relay 22B in the off-state and shuts off the conduction in the second power supply path 30B when an anomaly in the second power supply path 30B has been detected by the detection unit 27.
