First, in FIG. 1, at least a part of the outer surface of the vehicle V has at least flexibility when parked in a hot season. It is covered with a cover 11A that covers the front window 12. In the first embodiment, the cover 11A covers the left and right front side windows 13 of the vehicle V and the front of the roof 14 of the vehicle V in addition to the front window 12 of the vehicle V. The cover 11A is attached to the vehicle V by detachably engaging a plurality of attachment hooks 15, 15... Attached to the peripheral edge of the cover 11A on the vehicle V side.

  Moreover, the solar cell 16 is attached to at least a portion of the cover 11A that is disposed on the roof of the vehicle V. In the first embodiment, only the portion of the cover 11A that is disposed on the roof 14 of the vehicle V is provided. The solar cell 16 is attached. Further, an exhaust port 17 for exhausting air in the passenger compartment is provided on the rear outer surface of the vehicle V so as to prevent intrusion of water or the like from the outside to the passenger compartment side. Inside the vehicle V, a fan 18 capable of discharging the air in the passenger compartment to the outside is disposed.

  In FIG. 2, an engine 20 provided with a generator 19 is mounted on the vehicle V so as to transmit power to driving wheels such as left and right front wheels, and a battery 21 that can be charged by the generator 19. Is installed.

  The generator 19 is connected to the battery 21 via a charge control circuit 22 that controls charging of the power generated by the generator 19 to the battery 21, and various electric loads provided on the vehicle V are connected to the battery 21. 23 is connected. On the other hand, the solar cell 16 attached to the cover 11A is connected to the supply destination switching control means 24 disposed in the vehicle compartment via, for example, an electric wire inserted from a gap between the door and the vehicle body.

  The supply destination switching control means 24 includes a circuit switching unit 25 that switches between a state in which the electric power generated by the solar cell 16 is supplied to the fan 18 and a state in which the battery 21 is charged through the charging control circuit 22. , And a switching determination unit 26 that determines which state the circuit switching unit 25 is in. At least one of the detection value of the temperature sensor 27 that detects the temperature in the passenger compartment and the detection value of the power generation amount detection means 28 that detects the power generation amount of the solar cell 16 is input to the switching determination unit 26. Thus, in the first embodiment, both the detection value of the temperature sensor 27 and the detection value of the power generation amount detection means 28 are input to the switching determination unit 26, and the switching determination unit 26 detects the detection by the temperature sensor 27. When the value is lower than a predetermined temperature set so as to decrease as the detection value of the power generation amount detection means 28 increases, the battery 21 is charged with the power generated by the solar cell 16 in the circuit switching unit 25. State. When the value detected by the temperature sensor 27 is higher than the predetermined temperature, the switching determination unit 26 drives the fan 18 to discharge the air in the passenger compartment.

  The battery 21 is provided with an SOC sensor 29, which is a charge state detection sensor for detecting the state of charge (hereinafter referred to as SOC) of the battery 21, and the operation of the generator 19 is controlled by the SOC. The generator operation control means 30 controls based on the detection value of the sensor 29, whereby charging of the battery 21 by the generator 19 is controlled.

  Thus, the generator operation control means 30 starts charging by the generator 19 in response to the SOC detected by the SOC sensor 29 being equal to or lower than the first predetermined value S1, and the first predetermined value S1. Refresh that terminates charging by the generator 19 in response to the SOC reaching a second predetermined value S1 (for example, SOC 90%) that is set as a value that is greater than (for example, SOC 64%) and smaller than the fully charged state The charging of the battery 21 by the generator 19 is controlled so as to be charged.

  That is, as shown in FIG. 3, the state of charge of the battery 21 fluctuates somewhat due to discharge and regeneration when the vehicle is running, and decreases due to dark current discharge when the vehicle is stopped. Charging of the battery 21 by the generator 19 is started at time t1 when the SOC becomes equal to or lower than the first predetermined value S1, and charging to the battery 21 by the generator 19 is started at time t2 when the SOC reaches the second predetermined value S2. Charging is terminated, and the SOC of the battery 21 changes between the first predetermined value S1 and the second predetermined value S2.

  Next, the operation of the first embodiment will be explained. Since at least the front window 12 is covered with the cover 11A, it is possible to suppress the incidence of sunlight into the passenger compartment when parked outdoors in a hot season. In addition, since the fan 18 is operated by supplying the electric power obtained by the power generation of the solar cell 16 attached to the cover 11A and the air in the vehicle interior is discharged to the outside, it is avoided that the vehicle interior becomes hot. Thus, it is possible to prevent the passenger from feeling uncomfortable due to the high temperature in the passenger compartment when the vehicle enters the vehicle. Moreover, the charged state of the battery 21 is not deteriorated by the operation of the fan 18.

  In addition, when the temperature in the passenger compartment is lower than a predetermined temperature set to be lower as the power generation amount increases, that is, when the amount of solar radiation is small, the battery is charged with the power generated by the solar cell. Therefore, the charging load of the battery 21 by the generator 19 driven by the engine 20 mounted on the vehicle V can be reduced, and the energy consumption of the engine 20 can be reduced.

  Further, since the solar cell 16 is attached to at least a portion of the cover 11A that is disposed on the roof 14 of the vehicle V, the solar cell 16 that is disposed at least on the roof 14 of the vehicle V regardless of the direction of the vehicle V at the time of parking. Can generate electricity.

  Furthermore, charging by the generator 19 is started in response to the SOC of the battery 21 detected by the SOC sensor 29 being equal to or lower than the first predetermined value S1, and the charging is greater than the first predetermined value S1 and more than the fully charged state. Since the charging by the generator 19 is terminated in response to the SOC reaching the second predetermined value S2 set as a small value, the charging of the battery 21 by the solar cell 16 is performed. When performing, the battery 21 is not fully charged, and the battery 21 can be effectively charged by the solar cell 16.

  When the amount of power generated by the solar cell 16 is small, the battery 21 may be charged with the power generated by the solar cell 16, and when the temperature in the passenger compartment is low, as well as the amount of power generated by the solar cell 16.

  Thus, when the value detected by the temperature sensor 27 is higher than the predetermined temperature, the switching determination unit 26 charges the battery 21 with the electric power generated by the solar cell 16, and the value detected by the temperature sensor 27 is below the predetermined temperature. If so, the circuit switching unit 25 is controlled by supplying the power generated by the solar cell 16 to the heater 31.

  According to the second embodiment, the front window 12 is prevented from being frosted by the cover 11A, and the power obtained by the power generation of the solar cell 16 attached to the cover 11A is supplied, so that the heater 31 steers.

Then, the control unit 35 makes the relay 34 conductive so as to connect the power supply device 33 to the heater 31.

  According to the third embodiment, in order to supply sufficient power to the heater 31 whose power consumption is relatively large, the power generated by the solar cell 16 is stored in the power supply device 33, and sufficient power is supplied to the heater 31. The discomfort when getting into the vehicle can be alleviated by heating the vehicle seat 32.
