Title:
Power supply control system
Document Type and Number:
Japanese Patent JP6323719
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a control system for a power supply device that can safely move a vehicle when driving power for operating a vehicle is remarkably reduced.SOLUTION: A control system 10 for a power supply device is provided. A control system 10 includes a lithium ion secondary battery power supply unit (LIB unit) 22 and a lithium ion capacitor power supply unit (LIC unit) 24 as a power supply device 20, voltage measuring units 30a and 30b for measuring voltages of the two power supply units respectively, and a control unit 40 for controlling use of the two power supply units. The control unit 40 has an emergency control mode for comparing the voltage values measured at the two power supply units with a preset normal lower limit voltage, stopping the use of the lithium ion secondary battery power supply unit 22, and use the lithium ion capacitor power supply unit 24 alone in a voltage range equal to or lower than the normal lower limit voltage when all the measured voltage values are not more than the normal lower limit voltage.SELECTED DRAWING: Figure 1
