System, method of controlling system, and storage medium

A method of controlling a system, which is performed by a control device of a system comprising:

• a fuel cell configured to generate an electric power by reacting fuel of an anode with oxidant of a cathode;
• an electrical storage device configured to store the electric power generated by the fuel cell;
• an electric load to which an electric power is supplied using at least one of an electric power generated by the fuel cell and an electric power stored in the electrical storage device,
• a temperature detector configured to detect a temperature of the electrical storage device;
• a charged rate detector configured to detect a charged rate of the electrical storage device;
• and
• a heater provided at a position where heat is transferred to the electrical storage device and configured to generate heat using an electric power,
• the method comprising:
• controlling supply of an electric power from the fuel cell and the electrical storage device to the electric load;
• when warming-up of the fuel cell is necessary,
• performing warming-up control required for the fuel cell when an electric power requested to be generated at the fuel cell is less than a predetermined value;
• and
• when the electric power requested to be generated at the fuel cell is greater than the predetermined value, a temperature of the electrical storage device detected by the temperature detector is less than a predetermined temperature, and a charged rate detected by the charged rate detector is less than a predetermined proportion, causing the fuel cell to generate an electric power greater than the electric power requested to be generated at the fuel cell and causing to store excess electric power in the electrical storage device, causing to perform heating at the heater by supplying an electric power stored in the electrical storage device, in which the excess electric power has been stored, to the heater until the electrical storage device reaches a predetermined temperature and causing to stop the supplying the electric power stored in the electrical storage device to the heater and to store the excess electric power generated at the fuel cell in the electrical storage device after the electrical storage device has reached the predetermined temperature.

A computer program product, on which a program is stored, wherein the program is executable by a processor of a system, wherein the system comprises:

• a fuel cell configured to generate an electric power by reacting fuel of an anode with oxidant of a cathode;
• an electrical storage device configured to store the electric power generated by the fuel cell;
• an electric load to which an electric power is supplied using at least one of an electric power generated by the fuel cell and an electric power stored in the electrical storage device,
• a temperature detector configured to detect a temperature of the electrical storage device;
• a charged rate detector configured to detect a charged rate of the electrical storage device;
• and
• a heater provided at a position where heat is transferred to the electrical storage device and configured to generate heat using an electric power,
• and wherein execution of the program by the processor causes the processor to perform:
• processing of controlling supply of an electric power from the fuel cell and the electrical storage device to the electric load;
• when warming-up of the fuel cell is necessary,
• processing of performing warming-up control required for the fuel cell when an electric power requested to be generated at the fuel cell is less than a predetermined value;
• and
• when the electric power requested to be generated at the fuel cell is greater than the predetermined value, a temperature of the electrical storage device detected by the temperature detector is less than a predetermined temperature, and a charged rate detected by the charged rate detector is less than a predetermined proportion, processing of causing the fuel cell to generate an electric power greater than the electric power requested to be generated at the fuel cell and storing excess electric power in the electrical storage device, processing of causing to perform heating at the heater by supplying an electric power stored in the electrical storage device, in which the excess electric power has been stored, to the heater until the electrical storage device reaches a predetermined temperature and processing of causing to stop the supplying the electric power stored in the electrical storage device to the heater and to store the excess electric power generated at the fuel cell in the electrical storage device after the electrical storage device has reached the predetermined temperature.
