Abstract
A power supply control system includes: an electric device; an inverter; a first drive unit including a first fuel cell system, a first voltage converter, and a first battery; a second drive unit including a second fuel cell system, a second voltage converter, and a second battery; and a control unit that controls the inverter and/or the first fuel cell system so that a first current value flowing through the first battery reaches a target value of the first current value and controls the second voltage converter and/or the second fuel cell system so that a second current value flowing through the second battery reaches the target value of the first current value.
Claims7
A power supply control system comprising:
- an electric device;
- an inverter connected to the electric device to perform conversion from DC power to AC power;
- a first drive unit including a first fuel cell system that supplies DC power to the inverter, a first voltage converter that controls a voltage of a DC-side terminal of the inverter, and a first battery connected to the first voltage converter;
- a second drive unit including a second fuel cell system that supplies DC power to the inverter, a second voltage converter that controls a current in the inverter, and a second battery connected to the second voltage converter;
- and
- a control unit that controls the inverter and/or the first fuel cell system so that a first current value flowing through the first battery reaches a target value of the first current value and controls the second voltage converter and/or the second fuel cell system so that a second current value flowing through the second battery reaches the target value of the first current value.
A power supply control method for driving a power supply control system including:
- an inverter connected to an electric device to perform conversion from DC power to AC power;
- a first drive unit including a first fuel cell system that supplies DC power to the inverter, a first voltage converter that controls a voltage of a DC-side terminal of the inverter, and a first battery connected to the first voltage converter;
- a second drive unit including a second fuel cell system that supplies DC power to the inverter, a second voltage converter that controls a current in the inverter, and a second battery connected to the second voltage converter;
- and
- a control unit, wherein
- the control unit controls the inverter and/or the first fuel cell system so that a first current value flowing through the first battery reaches a target value of the first current value and controls the second voltage converter and/or the second fuel cell system so that a second current value flowing through the second battery reaches the target value of the first current value.
