Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention, when using a vehicle such as an electric vehicle which uses a battery as a driving energy source, starts an air conditioner prior to the use of the vehicle, and keeps the thermal environment inside the vehicle in use. The present invention relates to a pre-air conditioner capable of pre-air conditioning to a desired state.

[0002]

2. Description of the Related Art As a conventional pre-air conditioner of this type,
For example, there is one shown in FIG. 19 described in Japanese Utility Model Laid-Open No. 06-000823. That is, this pre-air conditioner is provided in an electric vehicle equipped with a traveling battery 101 and an in-vehicle charger 103, and the vehicle interior pre-heating control device 10 is provided.
The heating / cooling device 107 controlled by 5 is provided.
The power supply of the cooling / heating device 107 is connected to the output line of the in-vehicle charger 103. Then, the energization control for the vehicle interior preheating of the cooling / heating device 107 is performed based on the charging completion signal 109 issued after the in-vehicle charger 103 finishes the low current charging, and the cooling / heating device 107 is set to the outlet capacity after the charging is completed. It is used when there is room.

Therefore, when considering charging an electric vehicle at each home, it is not necessary to draw a large-capacity power supply line to the home by the above-mentioned device, and the cost can be reduced. That is, about 5 kW is used in the charging operation for the traveling battery 101, and
The operation of 7 uses about 2 kW. Exchange this 1
When converted to 00V, it becomes 50A and 20A respectively,
Both require considerably large electric power (there may be a charging operation from 200 V AC or 400 V AC). On the other hand, generally, household power supplies are
About 0 to 50 A is used. For this reason, considering charging an electric vehicle with a household power supply, it is necessary to newly draw a power supply line having a large capacity, resulting in a considerable cost increase.

In order to avoid this, the structure shown in FIG. 19 is adopted. First, the charging operation is prioritized, and the cooling / heating device 107 is operated after waiting for the completion of the charging operation. With this method, the power supply line to the home is 5
kW is good, and 5 kW (for charging) +2 kW (for air conditioning) = 7 kW (total) is not necessary. Therefore, it suffices to draw a power supply line having a small capacity, and the cost of the user can be reduced.

Further, there is one as shown in FIG. 20 disclosed in Japanese Patent Laid-Open No. 2-262419, Japanese Patent Laid-Open No. 2-287710, and the like. In this example, a plurality of heating means 109 are provided in the passenger compartment of the automobile, and each heating means 10 is provided.
The use priority order of 9 is set in advance, and the sum of the power consumptions added from the set use priority order is selectively operated so as to be the value closest to the allowable power quantity within the allowable power quantity of the vehicle-mounted power supply. Is. Therefore, the heating means 109 can be selectively operated so that the occupant is most comfortable within the allowable power amount of the vehicle-mounted power supply.

[0006]

However, as shown in FIG.
In the prior art example, since the cooling / heating device 105 is started after the charging operation of the in-vehicle charger 103 is completed, the charging rate of the battery 101 is low, and there is a difference between the actual thermal environment in the passenger compartment and the thermal environment desired by the occupant. It is large, and the charging operation is prioritized even under the condition that the time to make the desired thermal environment is approaching,
There was a problem that pre-air conditioning was not performed.

On the other hand, if the prior air conditioning is prioritized under the above-mentioned conditions, charging may not be sufficiently performed, the travelable distance of the vehicle is reduced, and the driving action range is narrowed. Therefore, it has been desired to achieve both charging operation and air conditioning operation.

Further, in the conventional example as shown in FIG. 20, since the heating means 109 is simply selected within the allowable power amount of the vehicle-mounted power source, the power supplied to each heating means 109 can be controlled. However, there is a problem in that the power supplied to the heating means 109 cannot be adjusted according to the power supplied to charge the battery.

Therefore, an object of the present invention is to provide a preliminary air conditioner capable of achieving both charging operation and air conditioning operation.

Further, the compressor 15 may be of a type in which the compression section and its drive motor are built in the pressure vessel or a type in which the motor is provided outside the pressure vessel.

The compressor 15 is as shown in FIG. That is, the compressor 15 is provided with a compressor unit 37 having a refrigerant compression chamber inside a compressor case 35. Compressor unit 37
Are linked to the motor unit 39 via a drive shaft 41. The motor unit 39 is composed of an AC three-phase motor. The refrigerant enters the compressor unit 37 from the suction pipe 43, is compressed, and is then discharged from the discharge pipe 45 to the refrigeration cycle. A compressor oil 47 is provided below the compressor case 35, and a compressor oil pump 49 faces the oil 47. The compressor oil pump 49 has a drive shaft 4

A glass wool 51 is provided around the compressor case 35 for heat insulation and sound insulation, and a soundproof box 53 is provided so as to surround the glass wool 51. A compressor heater 55 is provided below the compressor case 35 as a refrigerant compression means heating means. The heater 55 is an electric heater with a low voltage of, for example, DC 12V and 300W. A heat conduction plate 57 is provided between the heater 55 and the compressor case 35 to transfer the heat of the heater 55 to the compressor unit 37 side.

The wiring is connected to the motor unit 39 from the high-voltage wiring 59 through the connectors 61 and 63 by AC three-phase wiring. Further, the low-voltage wiring 65 is wired to the compressor heater 55 via the connector 67. The power supply for the compressor heater 55 is, for example, a high-voltage converted to a low-voltage by a DC-DC converter.

With the structure of the compressor 15 as described above, heating can be performed before operation, the oil 47 in the compressor 15 is reduced to a viscosity suitable for lubrication, and troubles relating to lubrication can be reduced. .

With the above-described structure, the air conditioner 1 performs the air conditioning operation in the passenger compartment, and the charging device 5 performs the charging operation for the battery 3.

In the air conditioner 1, the room temperature sensor 11 measures the vehicle interior temperature, and the air conditioning control amplifier 19 controls the air conditioner control amplifier 19 so that the measured temperature becomes the target temperature in the vehicle interior set by the room temperature setting device 13. The heater unit 9 is controlled. Then, an appropriate conditioned air is generated by the blower fan 7, and the temperature of this conditioned air is heat-exchanged by the cooler & heater unit 9 to be cooled / heated. In the charging device 5, the charging power supply connector 33 is connected to the household power supply, and the charging control device 21 controls the charging of the battery 3. The charge state in this case is monitored by the charge monitoring device 23.

The air conditioning operation and the charging operation are carried out while the time monitoring device 27 monitors the set target time, that is, the target time until the passenger re-boards and the current time. That is, the operating condition of the air conditioner 1 is determined by the air conditioner current supply device 25 in consideration of the charging state monitored by the charge monitoring device 23, the operating state of the air conditioning device 1, and the monitoring of the time monitoring device 27. That is, both the charging operation and the air conditioning operation can be achieved by the control of the air conditioner current supply device 25.

Here, the specific control will be described with reference to the flow charts of FIGS.

First, in step S1, data from the room temperature setting device 13 is input as data input thermal environment setting means. When performing pre-air conditioning, the occupant uses the room temperature setting device 13 to input the target thermal environment in the passenger compartment when re-boarding the vehicle and the target time for reaching the target thermal environment. Therefore, in step S1, the target thermal environment in the vehicle interior and the target time set by the room temperature setting device 13 are read.

In step S2, it is determined whether or not there has been a setting operation of pre-air conditioning for the thermal environment setting means. That is, if the target thermal environment and the target time have been set by the room temperature setting device 13, the process proceeds to step S3, and if not, the process proceeds from C to the pre-air conditioning control flowchart exit of FIG.

In step S3, it is determined whether or not the battery 3 is in a charged state. If it is not in the charging state, the process proceeds to step S4, and if it is in the charging state, the process proceeds to step S5.

In step S4, a charge promotion message is displayed. That is, the occupant is urged to perform the operation of charging the battery 3. The reason why such a charge promotion message is displayed is that if the electric power of the battery 3 is used during the pre-air conditioning, there is a problem that the traveling distance decreases due to the lack of the capacity of the battery 3 during the next boarding. . To avoid this,
At the time of pre-air conditioning, the occupant is required to charge the battery 3.

When charging from a household power source, the current once charged in the battery may be used for the air conditioner, or may be used for the air conditioner 1 without passing through the battery 3 from the charging device 5. .

In step S5, it is determined whether the charge capacity of the battery 3 is sufficient. That is, if the battery 3 is not at the predetermined voltage, it is determined that the charge capacity is insufficient. If the charge capacity is sufficient, the process proceeds to step S7, and if not, the process proceeds to step S6.

In step S6, an insufficient charge capacity and a charge promotion message are displayed to the occupant. As a result, the occupant is prompted to perform a charging operation, and the process proceeds from C to the pre-air conditioning control flowchart exit of FIG. That is, in this case, pre-air conditioning is not performed.

From step S7 onward in FIG. 4, the control for pre-air conditioning is performed. First, in step S7, the time until re-boarding is calculated, and this is called a margin time.

In the next step S8, the current thermal environment in the vehicle compartment is input. That is, the vehicle interior temperature detected by the room temperature sensor 11 is read.

In step S9, the thermal environment set by the passenger is input. That is, the target room temperature set by the room temperature setting device 13 is read. Then, from A to step S10 in FIG.
And estimate the time required for pre-air conditioning. For example, the calculation is performed using the following formula.

(Preliminary air conditioning required time) = [(target room temperature)-
(Current room temperature)] × (constant) However, the constant differs between cooling and heating. If the target room temperature is higher than the current room temperature, it is determined to be the heating operation, and if it is the opposite, it is determined to be the cooling operation. Further, if the difference between the target room temperature and the current room temperature is smaller than the predetermined value, the air conditioning operation is not performed.

Then, in the next step S11, it is determined whether the estimated pre-air conditioning required time is longer than the margin time. If it is longer, the process proceeds to the next step S12, and if it is not longer, the process proceeds to step S13. Then, based on this determination, it is determined whether or not the pre-air conditioning can be performed with a sufficient time margin. If this determination is “YES”, there is no time margin, and it is necessary to control according to the margin time and the margin power described later.

In step S12, the charging current is read from the charging monitoring device 23.

In step S13, the compressor heater 55 is activated. Generally, compressor heater 55
Is 300 W or less and is sufficiently small in view of the motor unit 39 of the compressor 15 that uses about 2 kW and the charging power that uses about 5 kW, and the compressor heater 55 is sufficient even when the battery 3 is being charged. Can be activated. The compressor heater 55 heats the components of the compressor 15 and the refrigerant in the compressor 15, and the lubricating oil in the compressor 15 dissolves well in the refrigerant. Therefore, the compressor 15
The lubrication characteristics at startup are improved, and troubles such as seizure of the compressor 15 can be prevented. Further, when the temperature of the constituent parts of the compressor 15 is high, the starting characteristic of the refrigeration cycle is improved, and, for example, the discharge pressure and the discharge temperature are increased quickly, so that the heating performance can be exhibited as quickly as possible.

In step S14, the difference between the charging current and the maximum charging current is calculated, and this is called the margin current.

(Margin current) = (Maximum charging current) − (Charging current) In step S15, the compressor heater 55 and the compressor 15 are controlled according to the illustrated compressor heater and compressor control map.

The drawings will be described here.

In the upper right part of the figure, "compressor heater → high speed compressor rotation" means that the compressor heater 55 is started and the compressor 15 is started at high speed after a predetermined time (for example, 10 minutes) has elapsed. To tell.
"Compressor high-speed rotation" in the lower right of the figure means that the compressor heater 55 is activated at a high speed and the compressor heater 55 is activated immediately. Needless to say, as the compressor 15 rotates at a higher speed, the refrigerant circulation amount of the refrigeration cycle increases, and the air conditioning performance improves. Of course, if the vehicle compartment reaches the target thermal environment after starting in this way, the compressor speed is reduced so as to maintain the thermal environment. The "compressor heater" at the lower left of the figure is to activate only the compressor heater 55 and improve the compressor activation characteristic, as in step S13. In the upper left part of the figure, "compressor heater → compressor low speed rotation" indicates that there is a lot of time to spare, so it is considered that charging the battery can be completed even if the compressor 15 is rotated at low speed, and the charging current is reduced. Even if it does, the compressor 15 is started. Note that the other sections can be similarly understood.

Next, the process shifts from B to step S16 in FIG. 6, and it is determined whether or not the compressor 15 is started.
If the compressor 15 is started, the process proceeds to step S17, and if not, the process exits to the flowchart.

In step S17, the charging current is temporarily reduced in consideration of using a higher current when the compressor is started than when it is stable. By such an operation, the sum of the air conditioning current and the battery charging current can be kept below a predetermined value.

Next, changes in the charging rate of the battery, the current supplied to the battery, the air conditioner operating current, and the like due to the above control will be described for each case.

First, FIG. 7 shows a graph for charging the battery. This graph plots the charging rate of the battery against time and the charging current for charging the battery. As is clear from this figure, the charging rate of the battery increases with time, but the increasing rate decreases as the charging rate expires, that is, approaches 100%. That is, the charging is not completed easily. On the other hand, the charging current is approximately 100% at first and is almost constant, but the charging current gradually decreases as time passes. That is, due to such a change in the charging current, a margin current starts to be output after 3 or 4 hours have elapsed from the start of charging.
Then, the above control is performed using such a margin current.

FIG. 8 shows changes in the charging rate of the battery, the current supplied to the battery, and the current used by the air conditioner with respect to time.
In order to make it easy to understand, a schematic diagram is shown in which noise during fine measurement is omitted. The example of FIG. 8 shows a case where there is a margin until the vehicle travel start time. in this case,
When the supply current of the battery falls below the specified value, the heater for the compressor starts, and the supply current to the battery falls below the specified value, which is smaller than the specified value.At the compressor start time, the compressor starts, and the vehicle interior starts by the time when the vehicle starts running. Can be set to a desired thermal environment. When the vehicle is running, the compressor slows down the speed so that the battery is not consumed.

FIG. 9 shows a case where there is not much time until the vehicle is used. In this case, there is no room to activate the compressor heater 55, and the compressor 15
Is starting up. However, since the charging is not completed, the charging current is monitored and the current consumption of the compressor is determined according to the surplus current. That is, the compressor 15
Even if the engine is started, the maximum current is not suddenly increased, but the current consumption in air conditioning is increased while gradually increasing the compressor speed in response to the decrease in the charging current. By thus controlling the charging operation and the pre-air conditioning operation at the same time, charging the battery and improving the comfort of the thermal environment inside the vehicle can be achieved at the same time. In this example, the power consumption of the compressor is considerably large even after the vehicle has traveled, that is, the desired thermal environment in the vehicle interior has not been sufficiently reached, so it is necessary to operate the compressor even when the vehicle is traveling. .

FIG. 10 shows an example of control in which the charging current is temporarily reduced in response to a large current (spike current) generated when the compressor is started. The unit of time is not the unit of time shown in FIG. 9, but the unit of second. The compressor start time is now displayed as 0 seconds. The charging current is rapidly reduced about 0.8 seconds before the compressor start time, and is restored to the original charging current after 0.4 seconds when the compressor reaches a predetermined steady current. By controlling in this way, it is possible to appropriately cope with a temporary increase in current consumption due to compressor startup, and it is not necessary to increase the capacity of the power supply for charging, and it is possible to reduce costs. .

In short, the high / medium / low rotation control of the compressor 15 of the air conditioner 1 and the control of the compressor heater 55 are selected depending on the balance between the spare time until the passenger re-boards and the spare current of the charging current. It is possible to achieve both the charging operation of the battery 3 and the pre-air conditioning operation by the air conditioner 1. Therefore, it is possible to prevent pre-air conditioning and insufficient charging, which makes it possible to optimize the thermal environment in the passenger compartment when the occupant re-boards, while maintaining a sufficient travel distance. can do.
Also, by keeping the sum of the air-conditioning current and the charging current below a predetermined value, when considering charging with a household power supply, it is only necessary to draw a smaller power supply line, thus reducing the cost for the user. You can

(Second Embodiment) FIGS. 11 and 12 show a flowchart according to the second embodiment of the present invention. In the flow chart of this embodiment, steps S1 to S14 of the flow chart of the first embodiment are the same and therefore not shown. And FIG. 1 of this embodiment
1, the step shown in FIG. 12 is step S1 of the first embodiment.
It is shown instead of 5. However, step S1
Since S6 and S17 are the same, the same step numbers are assigned and the description thereof is omitted.

First, in step S21 of FIG. 11, the heat load difference level is determined for two parameters, that is, the deviation between the target room temperature and the room temperature (detected room temperature) (room temperature deviation) and the room temperature. This heat load difference level is used in the next step, which is a quantified measure of the difference between a kind of target heat environment and the actual heat environment. For example, when the room temperature deviation (= target room temperature−room temperature) is 10 ° C., if the room temperature is 20 ° C., the heat load difference level is about 0.3, which is very small, but the room temperature deviation is about 30 ° C. and the room temperature is 0 ° C. At 0 ° C., the heat load difference level is about 10, which is very large. As the heat load difference level increases, the energy consumption in the air conditioner is controlled to increase as described later. This heat load difference level and steps S7 and S according to the first embodiment described above.
In step S22, the contents of the air conditioner to be activated are selected using the two parameters calculated in step 14, that is, the total of three parameters including the margin current and the margin time.

In the figure, "heater → compressor low speed" means that the compressor 15 is operated at a low speed after a predetermined time has elapsed after the compressor heater 55 was started. The meanings of the terms in the figures other than the above are understood in the same manner. Although only three parallelograms drawn diagonally are drawn, the control is actually continuous or piecewise depending on the heat load difference level. This figure is a control diagram drawn for a part of the heat load difference level for easy viewing.

This step S22 differs from step S15 of the first embodiment in that the higher the heat load difference level is, the more the margin current is the same, and even if the margin time is increased, the operating capacity (operating speed) of the compressor is increased. That is, the energy used for air conditioning is increased. This is because even if the difference between the target room temperature and the room temperature is the same, the energy consumption until the compressor starts up to a certain pressure temperature is different depending on whether the outside temperature is 5 ° C. or 15 ° C. even if the temperature difference is 20 ° C. Is. That is, the lower the outside temperature, the more energy consumed. For this reason, control according to the energy consumption is required. As a result, it is possible to perform pre-air conditioning that comprehensively evaluates not only the room temperature deviation but also various thermal environments.

It is also possible to improve the accuracy of the thermal environment by combining this control with the amount of solar radiation and the outside temperature.

Therefore, in this embodiment as well, substantially the same operational effect as that of the first embodiment described above can be obtained, and in addition, pre-conditioning that comprehensively evaluates various thermal environments such as the outside temperature can be performed, and more accurate pre-conditioning can be performed. It is possible to improve comfort during air conditioning and re-boarding.

(Third Embodiment) FIG. 13 shows a third embodiment of the present invention.
An example is shown. This FIG. 13 is used in place of step S21 of the second embodiment. That is, in step S31, the control is divided depending on whether the room temperature deviation (= target room temperature-room temperature) is larger than 0 (on the heating side) or small (on the cooling side). This is a division of the parameters used for control on the heating side and the cooling side. That is, the heat load difference level is calculated by using the room temperature deviation and the (compressor discharge gas temperature-outside air temperature) on the heating side, and the heat load difference level is calculated by the room temperature deviation and the outside air temperature on the cooling side. There is.

Here, on the heating side, the heat capacity of the compressor itself has a great influence on the initial heating performance.
The difference between the noise of the gas discharged from the compressor and the outside temperature is taken, and the larger this difference is, the smaller the heat load difference level is. On the contrary, if the temperature difference is large, the energy and time required to bring the compressor up to a predetermined pressure temperature state are large, so the heat load difference level is set to be large.

On the other hand, on the cooling side, the higher the outside air temperature, the higher the cooling load. Therefore, the outside air temperature was used for calculating the heat load difference level. The higher the outside temperature, the higher the heat load difference level. Therefore, in this embodiment as well, it is possible to obtain substantially the same operational effects as the second embodiment, and since the parameters used for control are divided between the heating side and the cooling side,
It is possible to perform more accurate air conditioning and heating, and it is possible to further improve comfort when the occupant is re-boarded.

(Fourth Embodiment) FIG. 14 shows a fourth embodiment of the present invention.
3 shows a flowchart according to an embodiment. This embodiment shows a control example when an air conditioning priority switch is provided. Therefore, in comparison with the flow chart of the first embodiment, FIG.
In the flowchart of the fourth embodiment of No. 4, step S4
1, step S42 is added. Other steps are first
This is the same as the embodiment, and in FIG. 14, the same step numbers as the steps in FIG. 4 are attached, and the steps corresponding to FIGS. 5 and 6 in the first embodiment are omitted.

That is, in step S41, it is determined whether or not the air-conditioning priority switch (not shown) in the air-conditioning operation section in the instrument panel in the vehicle compartment is pressed. If it is pressed, the process proceeds to step S42, and if not, the process proceeds to step S2.

In step S42, the compressor 15 is started in order to prioritize the air conditioning operation, the current amount required for starting the compressor is diagnosed, and the charging current is suppressed so as to fall below a predetermined value. Of course, if the charging current is a predetermined value or less from the beginning, it is not necessary to suppress it further. As a result, the compressor 10 can be activated to preferentially perform air conditioning regardless of the charging current. Although the use of this air conditioning priority switch depends on the occupant's judgment, it is generally the case that the mileage of the vehicle is relatively short and there is no problem even if charging is not completed. It is provided assuming that it will be used when it is far from the desired value. Of course, it is also possible to learn the daily running state of the vehicle and thereby change the charging completion state of the battery by the above-mentioned learning. That is, when the vehicle travels only a relatively short distance every day, it is not necessary to charge the battery to 100% at the time of charging, and the charging completion state is set to 85%, for example, to shorten the charging time, and It is possible to speed up the start-up of No. 1 and consequently give priority to the setting of the vehicle interior environment over the charging of the battery. However, in this case, it is necessary to notify the occupant of the battery charge state by some means.

Therefore, in this embodiment, if the air conditioning priority switch is not pressed, the same operation as in the first embodiment can be achieved, and if it is pressed, the air conditioning operation can be prioritized. Therefore, it becomes possible to perform control in accordance with the daily running state of the automobile.

(Fifth Embodiment) FIGS. 15 and 16 show a flowchart according to the fifth embodiment of the present invention. The fifth embodiment is a modification of the fourth embodiment provided with the air conditioning priority switch. In this embodiment, when the air conditioning priority switch is pressed, it is determined whether the charge capacity of the battery is equal to or more than a predetermined value, and the rotation speed of the compressor is controlled. Therefore, in this embodiment, instead of step S42 of FIG. 14 of the fourth embodiment, steps S51 and S5 of FIG.
2, S53. 15 and 16, the other steps are the same as those in the fourth embodiment, and the same step numbers are attached. In addition, steps S16 and S17 in FIG.
Although omitted from the illustration in the fourth embodiment, step S1 of FIG. 6 of the first embodiment which the fourth embodiment has in common.
6, the same as S17.

In this embodiment, if it is determined in step S41 that the air conditioning priority switch has been pressed, the process proceeds from step D to step S51 in FIG. 16 to determine whether the charge capacity of the battery is equal to or greater than a predetermined value. . Then, if the charge capacity is equal to or larger than the predetermined value, the process proceeds to step S53, and if not, the process proceeds to step S52.

In step S52, since the charge capacity of the battery is insufficient, the compressor 15 is started at low speed in order to be compatible with charging the battery. Step S53
Then, since it is considered that the charge capacity of the battery is sufficient, the activation of the air conditioner 1 is prioritized over the charging of the battery, the compressor 15 is activated at high speed, and the thermal environment in the passenger compartment is rapidly changed to the thermal environment desired by the occupant. It makes them close.

Although the degree of separation of the thermal environment from the thermal environment set by the occupant was not included in the starting condition of the air conditioner 1 here, for example, the greater the degree of separation, the higher the starting rotational speed of the compressor, It is also possible to bring the environment closer to the desired thermal environment more quickly. Judging the thermal environment in this way,
The air conditioner 1 can be prioritized more appropriately, and the battery 3
It can be compatible with the charging operation.

In this embodiment, substantially the same operational effect as in the above-described fourth embodiment can be obtained, and the battery charging operation and the air conditioning operation are performed in order to judge the charging capacity and control the rotation of the compressor. It is possible to achieve both more accurately.

(Sixth Embodiment) FIGS. 17 and 18 show a flowchart according to the sixth embodiment of the present invention. In this embodiment, in contrast to the first embodiment, the compressor is started at high speed when the difference between the room temperature and the set room temperature is large when pre-air conditioning is performed. Therefore,
In this embodiment, steps S61 and S62 are added between steps S9 and S10 of the first embodiment. Therefore, illustration is omitted up to step S9 shown in FIG. 4 of the first embodiment, and the other steps of FIGS. 17 and 18 are given the same numbers as the step numbers of FIGS. 5 and 6 of the first embodiment. are doing.

Then, in this embodiment, it is determined in step S61 whether the deviation between the room temperature and the set room temperature is 20 ° C. or more. If above 20 ° C, step S
If not, the process proceeds to step S10. In step S62, the compressor 15 is started at high speed, and the thermal environment is controlled so as to rapidly approach the set thermal environment. By controlling in this way, when the charge capacity of the battery 3 is judged to be equal to or greater than the predetermined value and is sufficient, and when the thermal environment is far from the set value, the compressor 15 is started at high speed, The thermal environment can be quickly brought close to the set value.

Therefore, in this embodiment as well, it is possible to obtain substantially the same effects as the above-mentioned first embodiment, and in the case where the charge capacity of the battery is equal to or greater than a predetermined value, the interior of the vehicle can be made comfortable quickly. You can

In each of the above embodiments, the compressor heater 55 is described as one type, but there are plural current capacities, and it is possible to appropriately switch between them. For example, one type is 300W and the compressor 1
The entire pressure vessel of No. 5 is heated, and the other type is a heater of 35 W, in which a current is supplied to the winding of the motor in the compressor 15. If the large and small heater systems are used as described above, it is possible to switch appropriately depending on the margin current, or to use both of them, so that the compressor 15 can be started more smoothly.

In the built-in motor type compressor 15, a so-called three-phase motor is used as the motor, and in the case of such a motor, the motor can be heated by supplying a current to only two of the three phases. . However, in such a method of heating the motor, the insulating seal of the motor winding may be thermally deteriorated, so it is important to prevent a large current from flowing. As the cold heat source, an electric heating means such as a PTC heater can be used in addition to the refrigerant compression means by the refrigeration cycle.
