Time after P) of, for power consumption is reduced, in order to selectively use the temperature difference coefficients D _A and D _B by the relationship room and hope temperature.

[0031] Then, as shown in FIG. 5, obtained in advance and the temperature difference coefficients D _A to the expected power relationship and the temperature difference coefficients D _B expected power consumption of the relationship from the respective measured data to approximately . The approximate expression to be obtained may be a linear approximate expression or a curve approximate expression.

At the same time determine the temperature difference coefficients D _B based on the outside temperature and the desired temperature, determine the expected power consumption corresponding from the approximate expression in this temperature difference coefficients D _B.

This is an example, and the estimated power consumption may be obtained by another method.

The function as the balance calculation means 138 is, for example, when the user who initially wants to cool or heat for one hour wants to stop the cooling or heating after 30 minutes, and turns on the stop switch 116. Then, since the remaining suppliable power amount is 250 Wh, an amount corresponding to the remaining suppliable power amount of 250 Wh, that is,
250 yen will be returned.

Next, the operation of the vehicle cooling / heating system will be described with reference to the flowcharts shown in FIGS.

FIGS. 6 and 7 are flowcharts on the power supply device 100 side, and FIGS. 8 and 9 are flowcharts on the cooling / heating unit 10 side.

The outside air temperature is detected by 0 (step S19). Then, in the expected power consumption calculating means 54, the room temperature sensor 48,
Based on the output signals from the outside air temperature sensor 50 and the desired temperature setting means 52, the expected power consumption required for cooling and heating is calculated (step S20).

The calculation result is output to the operation unit 130 of the power supply device 100 via the connection means 95, where the expected operation time per unit money is calculated (step S).
2), the estimated operating time is displayed on the display means 110 (step S3).

The user sees the expected operation time and inserts a currency of an amount corresponding to the desired time for cooling and heating into the coin slot 104 (step S 4), and the inserted currency is read by the amount reading means 122. And the payment amount is read.

Further, the power control unit 148 determines whether the stop switch 116 is ON (step S12). If it is determined in step S12 that the stop switch 116 has not been turned on, the power control means 148 further determines whether the remaining power consumption is zero (step S12). If it is determined in step S12 that the remaining power consumption is not zero, step S12 is repeated.
Returning to step 11, the operations of steps S11 to S13 are repeated. Also, in step S12, it is determined that the start switch 114 is ON, or in step S13
If it is determined that the remaining suppliable electric energy is zero, the ON / OFF relay 144 is turned off,

If the main switch 46 is not ON, the external power ON switch 44 is OFF or not. Is determined (step S24). When the main switch 46 is ON in step S23, and when the external power ON switch 44 is OFF in step S24, the connection is made from the cooling / heating control means 40 to the power control means 148 of the power supply device 100 via the connection means 95. A power supply stop command signal is sent out and the ON / OFF relay 144 is turned off.
The power supply is stopped by F (step S14). It should be noted that the time during which the remaining consumable power amount becomes zero in step S13 is not necessarily the time when the expected operation time has elapsed since the start of supply. Expected power consumption is a guide,
This is because the power actually consumed differs depending on factors such as changes in the outside temperature.

In step S24, the external power supply O
If the N switch 44 is not OFF, the cooling / heating control means 40 determines whether or not the power supply has been stopped based on the output signal from the power supply circuit section 42 (step S).
25) When it is determined that the power supply has not been stopped, the operations of steps S23 and S24 are repeated, and when it is determined that the power supply has been stopped, the operation of the cooling / heating unit 20 is stopped. (Step S25)
End cooling and heating.

On the other hand, on the cooling / heating device 20 side, Step S
When the power supply is stopped at 14, the power supply 100
If there is a balance by the balance return means 120, the balance is returned (step S15), and then "OFF" is displayed on the display means 110 (step S1).
6) End the operation.

According to the vehicle cooling / heating system configured as described above, by paying a predetermined amount, the amount of power that can be supplied to the electric vehicle 1 can be set in advance. In response to the above, it is possible to perform cooling and heating of the cabin of the electric vehicle 1 by supplying power from an external power supply device.

As more specific examples of use, for example, it is possible to perform cooling and heating while parking in a parking lot or to perform cooling and heating while watching a movie in a drive theater.

If the amount is paid not by currency but by a prepaid card or credit card, it is easy to pay the amount such as settlement of the balance.

Further, since the power supply cable 90 is provided with a power supply line and a signal line, the power supply cable 90
Power is supplied from the power supply device 100 to the electric vehicle 1 via the power supply device 1, and various control signals are exchanged between the two. Therefore, when a control signal is transmitted and received between the two via a radio, the transmission and reception of the control signal is limited to within the range of the radio wave, and a separate transceiver is required. Can be given and received.

However, transmission and reception of signals between the two need not necessarily be performed via a cable, but may be performed via radio waves, infrared rays, or the like, or power may be supplied by an inductive method.
