A power supply system of a hybrid vehicle
Document Type and Number:
Japanese Patent JP5990005
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve reliability of a hybrid vehicle.SOLUTION: A power supply apparatus 10 is provided with a high voltage circuit 24 including a motor generator 15 and a high voltage battery 23, a low voltage circuit 39 including an alternator 35 and a low voltage battery 38, and a control system circuit 33 including a converter 25 and control units 26 to 30. The control units 26 to 30 are connected to the high voltage circuit 24 via the converter 25. If a charge state SOC of the high voltage battery 23 as a power supply of the control units 26 to 30 is reduced, by switching a switching relay 50, the alternator 35 is connected to the control units 26 to 30, and the alternator 35 is controlled in a power generation state. Thereby, electric power can be supplied from the alternator 35 to the control units 26 to 30, and a control system can be functioned normally, allowing minimal travel performance to be secured.
