- a fuel cell system using a fuel cell that generates electricity by an electrochemical reaction between a fuel gas and an oxidizing gas as an energy source has attracted attention.
- the fuel cell system supplies high-pressure fuel gas from a fuel tank to the anode of the fuel cell, and pressurizes and supplies air as oxidizing gas to the cathode, causing these fuel gas and oxidizing gas to undergo an electrochemical reaction to generate electromotive force. Is generated. Development of vehicles equipped with such a fuel cell system is also underway.
- An in-vehicle fuel cell system is mainly composed of a fuel cell, a secondary battery, a travel motor, and an auxiliary machine.
- Patent Document 1 discloses that when an “N” position is selected, in order to prevent an excessive back electromotive voltage from being generated and to avoid a sense of incongruity due to the generation of a regenerative braking force, The target power calculation means uniformly sets the target voltage to zero so that the motor does not generate drive torque or regenerative torque.
- a high potential avoidance control that suppresses the total voltage of the fuel cell from exceeding a predetermined threshold or a temperature increase of the fuel cell in a shorter time than normal operation
- various power generation states such as warm-up operation. Therefore, as with normal electric vehicles, if the permission / non-permission of shutdown is controlled uniformly according to the number of rotations of the motor, the back electromotive voltage is larger than the maximum output voltage of the fuel cell depending on the power generation state of the fuel cell For example, the power supply control of the entire system may be affected.

- the maximum value VMAX of the inverter voltage (for example, the open end voltage of the fuel cell stack) is the upper limit of the allowable back electromotive voltage. Accordingly, the upper limit rotational speed NCONST corresponding to the upper limit voltage VMAX is set as the rotational speed threshold.
- the high potential avoidance control mode is an operation mode in which the output voltage of the fuel cell 40 is forcibly lowered below a predetermined voltage threshold (high potential avoidance voltage threshold) in order to suppress the progress of deterioration of the fuel cell.

- the maximum output voltage Va of the fuel cell 40 in the high potential avoidance control mode in other words, the high potential avoidance voltage threshold is the upper limit of the allowable back electromotive voltage. Accordingly, the upper limit rotational speed Na corresponding to the maximum output voltage Va is set as the threshold value.

It is a mode.
- the reaction gas oxidizing gas or fuel gas
- the reaction gas is made insufficient to increase the power loss compared to the normal operation, that is, the power generation efficiency of the fuel cell 40 is reduced and the heat generation amount is increased. This is realized by a low-efficiency operation to be performed or an operation to increase the amount of heat generated by power generation by increasing the output current of the fuel cell 40.
- the conversion to the warm-up operation mode is controlled based on the FC temperature, for example. Specifically, when the FC temperature is lower than a predetermined temperature threshold, the control device 10 sends a control signal to each unit so as to enter the warm-up operation mode.
- the maximum output voltage Vb during the warm-up operation is the upper limit of the allowable back electromotive voltage. Therefore, the upper limit rotation speed Nb corresponding to the maximum output voltage Vb is set as the threshold value.
- step S01 when a shift position detection signal is input from the operation unit 2 to the control device 10, the control device 10 determines whether or not the signal represents a “N (neutral)” range (step S01). S02).
- step S03 the control device 10 determines whether or not the current operation mode of the fuel cell 40 is the warm-up operation mode.

- step S12 the control device 10 sets the upper limit rotational speed Na in the high potential avoidance control mode as the rotational speed threshold value.
- step S05 the control device 10 sets the upper limit rotation speed NCONST in the normal operation mode as the rotation speed threshold value.
- step S06 the control device 10 compares the current rotational speed of the motor 61 with the rotational speed threshold set in any of steps S11, S12, and S05. Then, when the current rotational speed is smaller than the rotational speed threshold, the shutdown is permitted (step S07). Thereby, inverter control with respect to the motor 61 stops.
- step S13 if the current rotational speed is greater than or equal to the rotational speed threshold, the shutdown is not permitted (step S13). This prevents the generation of counter electromotive force exceeding the maximum output voltage (VMAX, Vb, Va) in each operation mode. In this case, the shutdown is permitted when the operation mode of the fuel cell 40 is switched, or when the rotational speed of the motor 61 becomes smaller than the threshold value due to a brake operation or natural deceleration.
- the auxiliary machines are connected to the battery side with respect to the DC / DC converter, but the auxiliary machines are connected to the DC / DC converter.
- the present invention may be applied to a configuration connected to the fuel cell side. In this case, exceeding the rated voltage of the auxiliary inverter due to an excessive counter electromotive voltage can also be suppressed.
