<P>PROBLEM TO BE SOLVED: To suppress an execution of unnecessary heat insulating operation to inhibit useless fuel consumption. <P>SOLUTION: Freezing of water inside fuel cell stacks 20 is predicted from atmospheric temperature T2 (S120-S140) while halting driving of an electric vehicle, and the predicted result is transmitted to a communication terminal apparatus 60 remote from the electric vehicle 10 through data communication (S150). A user of the communication terminal apparatus 60 sees the predicted result sent from the communication terminal apparatus 60 on a display unit 80 (S210) and determines whether a heat insulation operation is necessary or not based on the predicted result. The user transmits the determined result to ECU 40 of the electric vehicle 10 (S230). The ECU 40 receives the determined result (160) and permits or inhibit to execute the heat insulation operation running routine for carrying out the heat insulation operation based on the determined result (S170, S180). <P>COPYRIGHT: (C)2005,JPO&NCIPI |
