JP 2007-252016 A

  In a conventional vehicle, while the electric power supplied from the charging device outside the vehicle is charged to the power storage device, the motor and the in-vehicle device, for example, an air conditioner for adjusting temperature (hereinafter referred to as “air conditioner”) is stopped. Therefore, in the summer when the ambient temperature of the vehicle is higher than the comfortable temperature (for example, 25 ° C.), the temperature in the vehicle main body becomes high, for example, 50 ° C. to 60 ° C., and in the winter, the temperature in the vehicle main body is, for example, 0 It was lower than the comfortable temperature of 10 ° C to 10 ° C.

  For this reason, when the temperature inside the vehicle body is adjusted again to a comfortable set temperature after the charging is completed, the temperature difference between the temperature inside the vehicle body and the set temperature increases, the operation time of the air conditioner becomes longer, The amount of power used to adjust the temperature inside the vehicle body to the preset temperature, such as “High”, increases, and the amount of power stored in the power storage device increases. There was a problem of shortening.

  In view of the above, an object of the present invention is to suppress the consumption of electric power stored in the power storage device even when the temperature in the vehicle body is adjusted, and to suppress the distance that can be traveled by the motor from being shortened.

  In order to achieve this object, a vehicle according to the present invention includes a power storage device that stores power supplied to a power supply port of a vehicle body, a wheel drive unit that rotates a wheel by the power stored in the power storage device, and a power supply port.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the drawings, the same or corresponding parts will be described with the same reference numerals.

(Embodiment 1)
First, an outline of the vehicle charging system in the first embodiment will be described with reference to FIG. Here, as an example, a case of an electric vehicle in which a power storage device and a motor as a wheel drive unit that rotates wheels are mounted as the vehicle and the motor is driven using the charging power of the power storage device will be described.

  FIG. 1 is a schematic diagram showing a configuration of a vehicle charging system 1 according to Embodiment 1 of the present invention. In FIG. 1, a vehicle charging system 1 includes a charging device 3 and a vehicle 2 connected to the charging device 3 via a power line 4.

  In a general house 6, the charging device 3 is installed in a place adjacent to the house 6 and connected to the power source 7 of the house 6. For example, the power plug of the charging device 3 is connected to an outlet outside the house connected to the power line 7 a of the power source 7. Thereby, the electric power required for the charging device 3 is supplied from the power supply 7 of the house 6, and the charging apparatus 3 can supply electric power to the vehicle 2 using the electric power of the power supply 7 of the house 6.

  With such a configuration, in the vehicle charging system 1, power is supplied from the charging device 3 to the power supply port 5 of the vehicle 2 through the power line 4, and the power supplied to the power supply port 5 is charged to the power storage device 8. The

  Next, FIG. 2 is a schematic diagram showing the configuration of the vehicle 2 of the vehicle charging system 1. As shown in FIG. 2, the vehicle 2 charges the power storage device 8 with electric power supplied from the power supply port 5 of the vehicle main body 2 a. In the vehicle 2, after charging is completed, the motor 17 is driven using the electric power stored in the power storage device 8 to rotate the wheels 18. Similarly, the power stored in the power storage device 8 is supplied to an in-vehicle device such as the air conditioner 10 through the power line 8a, and the in-vehicle device is operated by this electric power.

  As described above, since the vehicle 2 is charged with the power stored in the power storage device 8 to operate all the on-vehicle devices and the motor 17 after charging, the travel distance depends on the power consumption of the power storage device 8. Will be.

  Here, when using an AC power source used in a general house 6, AC power cannot be directly supplied to the power storage device 8, so an in-vehicle charging device 9 is provided between the power supply port 5 and the power storage device 8, Electric power supplied from the power supply port 5 is converted from alternating current to direct current by the in-vehicle charging device 9, and the converted electric power (direct current) is supplied to the power storage device 8. In addition, when a DC power source is connected to the power supply port 5, the in-vehicle charging device 9 may not be provided.

  FIG. 3 is a block diagram illustrating a configuration of the vehicle 2 of the vehicle charging system 1. As shown in FIG. 3, the power supply port 5 is connected to the power storage device 8 through a power line 9 a, an in-vehicle charging device 9, and a power line 9 b.

  When the vehicle 2 is charged, the vehicle owner leaves the vehicle 2 with the vehicle key and stops the vehicle 2 so that the vehicle 2 does not start, for example, the vehicle 2 starts without permission, that is, the power storage device for safety. The power supply from 8 to the motor drive unit 16 and the power supply to in-vehicle devices such as the air conditioner 10 are stopped. Specifically, when the vehicle 2 is stopped, the switch 15 provided in the middle of the power line 8 a and the power line 8 b is opened, that is, disconnected from the power storage device 8 by the vehicle control unit 14. The supply of power to the motor drive unit 16 and various in-vehicle devices is stopped.

  After bringing the vehicle 2 into a stop state, the vehicle owner connects the connection plug of the power line 4 from the charging device 3 to the power supply port 5 of the vehicle 2 and supplies power from the charging device 3 to the vehicle 2.

  When the vehicle owner uses the vehicle 2 again after charging, the vehicle owner puts the vehicle 2 into an operating state using the vehicle key. When the vehicle 2 is in the operating state, the vehicle control unit 14 closes the switch 15, that is, the connection state, and power is supplied from the power storage device 8 to the in-vehicle devices such as the motor driving unit 16 and the air conditioner 10. Thereby, in the vehicle 2, the electric power stored in the power storage device 8 can be used by the motor 17 and the air conditioner 10.

  By the way, since the charging time of the vehicle 2 needs 20 minutes to several hours, if the air conditioner 10 is stopped during the charging period, the ambient temperature of the vehicle 2 is higher in summer than the comfortable temperature (for example, 25 ° C.). The temperature in the vehicle main body 2a increases steadily and increases, for example, from 50 ° C. to 60 ° C. In winter, the temperature in the vehicle main body 2a decreases from 0 ° C. to 10 ° C., for example, compared to the comfortable temperature. For this reason, when the temperature in the vehicle main body 2a is adjusted again to a comfortable set temperature after completion of charging, the temperature difference between the temperature in the vehicle main body 2a and the set temperature becomes large, and the temperature in the vehicle main body 2a is adjusted by the air conditioner 10. The amount of power used for adjusting to the set temperature increases, and the amount of power stored in the power storage device 8 increases. For this reason, even when the battery is fully charged, valuable electric power is consumed, thereby shortening the distance that can be traveled by the motor 17 using the power storage device 8.

  Therefore, in the first embodiment, even when the temperature inside the vehicle main body 2a is adjusted by the air conditioner 10, the consumption of the electric power stored in the power storage device 8 is suppressed. FIG. 4 is a block diagram showing a configuration of the air conditioner 10 mounted on the vehicle 2 shown in FIG.

  That is, as shown in FIGS. 3 and 4, the air conditioner 10 includes a temperature detection unit 11 that detects the temperature in the vehicle body 2a and a temperature setting unit 10a that sets the temperature detected in the vehicle body 2a. A temperature adjusting unit 10b that adjusts the temperature in the vehicle main body 2a so as to reduce the difference from the set temperature, and power supplied to the power supply port 5 (the power line 9a, the in-vehicle charging device 9 and the power line from the power supply port 5) A power switching unit 10c that outputs one of a power supplied from the power storage device 8 (a power supplied from the power storage device 8 via the power line 8a) to the temperature control unit 10b; The temperature for controlling the power switching unit 10c and the temperature adjusting unit 10b according to the detection result of the connection detection unit 12 that detects that the power supply plug of the power line 4 (FIG. 1) is connected to the power supply port 5 Control unit 10d, and when the temperature detection unit 10d detects that the power supply plug is connected to the power supply port 5, the temperature control unit 10d supplies power supplied to the power supply port 5 to the power switching unit 10c. The temperature adjusting unit 10b is configured to output the temperature and the temperature adjusting unit 10b is configured to adjust the temperature in the vehicle main body 2a. When the power supply plug is inserted into the power supply port 5, the connection detection unit 12 detects a connection state by short-circuiting a predetermined terminal.

  Thereby, the temperature control part 10d can adjust the temperature in the vehicle main body 2a to the set temperature during charging by the temperature adjustment part 10b using the electric power supplied to the power supply port 5. For this reason, when adjusting the temperature in the vehicle main body 2a to the set temperature after charging, the temperature difference between the temperature in the vehicle main body 2a and the set temperature can be reduced, so that the operating time of the temperature adjusting unit 10b is reduced. This shortens the driving operation and makes it possible to reduce the power consumption. Thereby, consumption of the electric power stored in the power storage device 8 is suppressed, and it is possible to suppress a reduction in the travel distance that can be traveled by the motor 17. Furthermore, even when charging while shopping at a nearby store in summer or winter, the interior of the vehicle body 2a can be kept at a comfortable temperature, can be set to a set temperature in a short time, and can go home. In addition, the interior of the vehicle body 2a can be brought to a comfortable temperature.

  Note that a power detection unit 10e may be newly provided to detect the power supplied to the power supply port 5. When power is supplied to the power supply port 5, the on-vehicle charging device 9 is activated, and a DC output voltage is generated on the power line 9 c. The power detection unit 10e detects the voltage generated on the power line 9c and detects whether or not the voltage is equal to or higher than a predetermined value (for example, 12 volts or higher). It can be detected whether or not. That is, the power detection unit 10e supplies power to the power supply port 5 if the voltage of the power line 9c is equal to or higher than a predetermined value, and supplies power to the power supply port 5 if the voltage of the power line 9c is less than a predetermined value. Detect that it is not. In this case, when the voltage of the power line 9c becomes equal to or higher than a predetermined value by the power detection unit 10e, the temperature control unit 10d causes the power switching unit 10c to output the power supplied to the power supply port 5 to the temperature adjustment unit 10b. The temperature adjusting unit 10b adjusts the temperature in the vehicle main body 2a.

  Thereby, for example, even when the vehicle charging system 1 is a system that supplies power from the charging device 3 by authentication of the vehicle 2 and the connection plug is connected to the power supply port 5, power is not yet supplied to the power supply port 5. In addition, the temperature adjusting unit 10b can be stopped until power is supplied to the power supply port 5. When power is supplied to the power supply port 5 (during charging of the power storage device 8), the temperature adjusting unit 10b is activated. To start. In this way, the air conditioner 10 can adjust the temperature in the vehicle main body 2a to the set temperature during charging. Further, if the power detection unit 10e is used instead of the connection detection unit 12, the connection detection unit 12 may be omitted.

  Further, the temperature control unit 10d is connected to the power supply unit 10f and is operated by the power from the power supply unit 10f. Thus, the temperature control unit 10d monitors the detection result of the connection detection unit 12 that detects whether or not the power supply plug of the power line 4 is connected to the power supply port 5 even when the vehicle key is stopped. be able to. The power supply unit 10f is composed of, for example, a battery.

  FIG. 5 is a block diagram showing the configuration of the in-vehicle charging device 9 placed on the vehicle 2 shown in FIG. As shown in FIG. 5, when AC power is supplied from the power supply port 5, the in-vehicle charging device 9 includes an AC / DC conversion unit 21, and receives AC (for example, voltage 100 to 200 volts) power. It is converted into electric power of direct current (for example, as will be described later, about 300 volts as the voltage used for the motor power storage unit 22 in FIG. 6 or 12 volts to 14 volts as the voltage used for the on-vehicle equipment power storage unit 23). With this configuration, the in-vehicle charging device 9 converts the power supplied from the power supply port 5 to the terminal A from AC to DC, and supplies the converted power (DC) from the terminal B to the power storage device 8 via the power line 9b. To do. In addition, the power supplied from the terminal C to the power supply port 5 through the power line 9 c is converted into a direct current (voltage 12 to 14 volts) for in-vehicle equipment and supplied to the air conditioner 10.

  FIG. 6 is a block diagram showing a configuration of power storage device 8 placed on vehicle 2 shown in FIG. As shown in FIG. 6, the power storage device 8 includes a motor power storage unit 22 and a vehicle-mounted device power storage unit 23.

  The motor power storage unit 22 charges the power from the input terminal, internally boosts the charged power of about 300 volts to, for example, 500 volts to 700 volts, and outputs it to the output terminal A. The boosted power is supplied from the output terminal A to the motor drive unit 16 (FIG. 3) via the power line 8b and the switch 15 (FIG. 3). The on-vehicle equipment power storage unit 23 charges power from the input terminal, and the charged power (for example, 12 to 14 volts) is supplied to the air conditioner 10 (FIG. 3) or the like via the power line 8 a and the switch 15. Supply power to in-vehicle devices.

  FIG. 7 is a flowchart showing the operation of the vehicle 2 shown in FIG. First, as shown in FIG. 7, the vehicle 2 detects whether the power supply plug of the power line 4 is connected to the power supply port 5 by the connection detection unit 12 (S100).

  Next, when the power supply plug is connected to the power supply port 5 (S102), the vehicle 2 charges the power storage device 8 with the power supplied to the power supply port 5 (S104). Then, the vehicle 2 causes the temperature control unit 10d to cause the power switching unit 10c to output the power supplied to the power supply port 5 to the temperature adjustment unit 10b (S106), and causes the temperature adjustment unit 10b to set the temperature inside the vehicle body 2a. Adjust (S108).

  Note that the vehicle 2 repeatedly executes (S100) to (S108) while the power supply plug is connected to the power supply port 5, that is, during charging.

  On the other hand, when the power supply plug is not connected to the power supply port 5 (S102), the vehicle 2 outputs the power supplied from the power storage device 8 to the power switching unit 10c to the temperature control unit 10b by the temperature control unit 10d. (S110).

  Here, when the vehicle 2 adjusts the temperature in the vehicle main body 2a (S112), the temperature adjustment unit 10b adjusts the temperature in the vehicle main body 2a (S108), and then returns to (S100). , (S102), (S110) and (S112) are executed. On the other hand, when the temperature in the vehicle main body 2a is not adjusted (S112), the vehicle 2 returns to (S100) and executes (S100), (S102), (S110), and (S112).

  As described above, according to the first embodiment, as shown in FIGS. 2, 3, and 4, vehicle 2 includes power storage device 8 that stores power supplied to power supply port 5 of vehicle body 2 a, The motor 17 that is a wheel drive unit that rotates the wheel 18 by the electric power stored in the device 8, the connection detection unit 12 that detects that the power supply plug is connected to the power supply port 5, and the temperature inside the vehicle body 2 a are detected.

A temperature adjusting unit 10b that adjusts the temperature in the vehicle body 2a, a power switching unit 10c that outputs either the power supplied from the power supply port 5 or the power supplied from the power storage device 8 to the temperature adjusting unit 10b, Connection detector And a temperature control unit 10d for controlling the power switching unit 10c and the temperature adjustment unit 10b according to the detection result of No. 2, and the temperature control unit 10d indicates that the connection detection unit 12 has connected the power supply plug to the power supply port 5. When detected, the power switching unit 10c is caused to output the power supplied from the power supply port 5 to the temperature adjusting unit 10b and the temperature adjusting unit 10b is configured to adjust the temperature in the vehicle body 2a.

  With this configuration, the temperature control unit 10d can adjust the temperature in the vehicle main body 2a to the set temperature during charging by the temperature adjustment unit 10b using the power supplied to the power supply port 5. For this reason, when adjusting the temperature in the vehicle main body 2a to the set temperature after charging, the temperature difference between the temperature in the vehicle main body 2a and the set temperature can be reduced, so that the operating time of the temperature adjusting unit 10b is reduced. This shortens the driving operation and makes it possible to reduce the power consumption. Thereby, consumption of the electric power stored in the power storage device 8 is suppressed, and it is possible to suppress a reduction in the travel distance that can be traveled by the motor 17.
