A C controller and a vehicle controller for controlling the electric motor 3 are provided, and the following control operations are executed while transmitting and receiving necessary data between the two controllers.

When the control flow starts, first, various abnormality flags, numerical values, etc. are initialized (step S1), the current value of the battery capacity (ampere hour [AH]) is read from the built-in nonvolatile memory, and the low power state (Steps S2 and S3). The small power state refers to a state in which a small current required to secure a standby state of control is being supplied.

The presence or absence of a vehicle start signal (main switch ON / OFF signal, timer signal, etc.) is determined. If there is no such signal, the standby in the low power state is continued, and if there is, the low power state is released. (Steps S4 and S5).
It should be noted that the timer signal is a start signal for transmitting a signal at regular time intervals to start the fuel cell device 2 even when the vehicle is stopped, so that the fuel cell device 2 is fully charged for the next run. Means

If the vehicle start signal is a timer signal, the battery capacity is detected. If it is determined that charging is unnecessary, the self-discharge amount is calculated, and the battery capacity is calculated (steps S7 to S10). ), And return to step S3. On the other hand, if the vehicle start signal is a signal indicating that the main switch has been turned on, various registrations such as a user event reservation and a start prohibition setting of the fuel cell device 2 are performed (step S11). Various signals such as a seat switch, a stand switch, a brake switch, and a throttle angle sensor are read, and a water circulation subroutine (described later) is executed based on the detected values (steps S12 to S12).

Also, the presence or absence of a battery abnormality is determined based on the detection result of step S14. If there is no battery abnormality, the battery relay is turned on, and abnormality display processing is performed (steps S23 to S25).

When the main switch is on,
If the fuel cell device 2 is operating in the off state, the process proceeds to step S12. On the other hand, when the main switch is off and the fuel cell device 2 is stopped, the value of the battery capacity is written in the non-volatile memory (steps S29 to S31), and when the battery is connected, the process returns to step S3. If not, the process ends (step S32).

The temperature detected by the water temperature sensor A is equal to the predetermined temperature T.
If not, the outlet of the three-way valve X is opened, and water is immediately supplied to the battery water tank 30 (step S13-4). When the temperature detected by the water temperature sensor B disposed downstream of the water tank 31 for the motor driver 3a is equal to or higher than a predetermined temperature Tb (for example, 90 ° C.), the three-way valve Y and the three-way valve Z have their outlets and outlets open ( In steps S13-5 to S13-6), the water that has passed through the battery water tank 30 is supplied to the cell stack 9 through the bypass 33c without passing through the water tanks 10 and 31.
