Description

A low-power heat pump-based low-power air conditioning system for commercial vehicles with both heating and cooling {AIR CONDITIONER SYSTEM FOR HEAT PUMP BASED HEATING AND COOLING FOR TRUCK WHEN ENGINE STOPPED}

The present invention relates to an air conditioner for commercial vehicles, and more specifically, to a non-starting air conditioner for both cooling and heating for commercial vehicles that is driven at low power based on a heat pump, and to the battery of the vehicle when the operation of commercial vehicles such as trucks and special vehicles in addition to passenger cars is stopped. It uses electric power to operate a low-power air conditioner based on a heat pump that is supplied with power from a battery installed in a commercial vehicle without starting the engine. In particular, it is charged using the energy source of solar energy during normal times, and when operating a commercial vehicle such as a truck, the vehicle's conditioner is operated at low power. Charging efficiency is increased by charging using a generator as an energy source, but solar power generation power is charged to a separate battery even while the air conditioner battery is being charged using engine output. This is a heat pump-based low power system equipped to improve charging efficiency. This relates to a non-starting air conditioning system for both heating and cooling for commercial vehicles that is driven by .

In general, trucks and other commercial vehicles burn fuel such as diesel, gasoline, or gas to start the engine, and the vehicle is driven by starting the engine.

In this way, the electricity required when driving a commercial vehicle is supplied from the vehicle's generator according to the operation of the engine. By receiving electricity from the vehicle generator and operating the air conditioner to keep the interior of the vehicle cool, drivers can safely operate commercial vehicles.

In general, among commercial vehicles, trucks are mainly used for long-distance night driving while carrying cargo, and when driving at night, they park at a place such as a rest area and sleep in the space provided behind the driver's seat. In this case, you will need to cool off in the summer, and you will need to warm up in the winter to be able to rest comfortably.

However, as idling for long periods of time is prohibited according to related regulations, it is difficult to receive electricity from the engine's generator, making it difficult to operate electrical appliances.

Therefore, conditions should be created where people can rest comfortably by being able to use electric appliances even without starting the engine of a commercial vehicle such as a truck.

Additionally, in recent years, vehicles have been used for camping, so camping vehicles have their engines stopped and use the vehicle battery to operate electrical appliances. However, since the capacity of a vehicle's battery is generally limited to be used when the vehicle engine is running, there is a risk that the battery will be consumed quickly if other electrical appliances are used without the engine running. Therefore, in case of camping, there is a disadvantage of using a separate auxiliary battery.

In this way, there is a need for a technology configuration that can stably supply power over a long period of time without power supply from the engine generator in commercial vehicles such as trucks or camping vehicles. In addition, technical proposals for charging and power supply systems are urgently needed to ensure optimal power operation through the vehicle's battery power.

In addition, proposals for charging technology using engine power generation and solar power generation, as well as convenient configurations for operation, are needed.

In the heat pump-based low-power non-starting air conditioning system (10) for commercial vehicles that is driven at low power according to the present invention, electricity generated by the solar power generation device (20) is used along with the power generated by the engine generator (11) according to engine start. When the power generation power is generated, the power generation power of the engine generator 11 can charge the engine battery 12, which is the battery of the vehicle, and charge the non-starting air conditioner battery 31 for operating the non-starting air conditioner operating unit 30. there is.

While charging the idle air conditioner battery 31 by the engine generator 11, the power generation power of the solar power generation device 20 is charged to a separate battery, thereby generating power from the solar cell along with power from the engine power generation. All of them can be used as a charging power source.

As a configuration for this, the power generated from the solar power generation device 20 is received and charged under the control of the power controller 501, and the charging power is supplied to the passive air conditioner operating unit 30 under the control of the power controller 501. ) is provided with a damper battery (35) that is applied.

And it includes a damper battery power monitoring unit 535 that is connected to the damper battery connection unit 515 of the damper battery 35 and receives information about the remaining charge of the damper battery 35 and transmits it to the battery power control manager 56. Thus, the charging power of the damper battery 35 can be monitored, and this monitoring information is transmitted to the power controller 501.

That is, the power generation status information of the engine generator 11 is transmitted from the engine power generation power monitoring unit 531 connected to the engine power generation connection unit 511 of the engine generator 11, and the solar power generation connection unit of the solar power generation device 20 is transmitted. Power generation status information from the solar power generation device 20 is received from the solar power generation power monitoring unit 534 connected to (514) and the monitoring information is transmitted to the power controller 501.

Accordingly, the power controller 501 receives monitoring information on the power generation status of the engine generator 11 and the solar power generation device 20 from the power generation power control manager 55, and monitors the power generation status of the engine generator 11 and the solar power generation device 20. When all of the devices 20 are in the power generation state, the power generation power of the engine generator 11 sends control information for power application to the non-starting air conditioner battery 31, and the power generation power of the solar power generation device 20 sends it to the damper battery 35. ) side, the control information of power application is transmitted to the power generation power control manager (55).

And the power generation power control manager 55 controls the power generation power of the engine generator 11 to be applied from the engine power generation connection unit 511 to the non-starting air conditioner battery 31 through the air conditioner battery connection unit 513, and solar power The power generation device 20 is controlled to be applied from the solar power generation connection unit 514 to the damper battery 35 through the damper battery connection unit 515.

As a result, the damper battery 35 is charged with the power generation power of the solar power generation device 20, and the non-operating air conditioner operating unit 30 is operated with the charging power of the damper battery 35 in the future.

In this state, when the damper battery 35 is charged, when operating the non-starting air conditioner operating unit 30, power is supplied to the damper battery 35 together with the non-moving air conditioner battery 31 to operate the non-moving air conditioner operating unit. (30) is activated.

Accordingly, the remaining charge of each battery is monitored by the battery power control manager 56 by receiving data from each power monitoring unit, and the monitoring information is transmitted to the power controller 501. Thus, the power controller 501 When the remaining charge of each battery stored in the control memory 502 reaches a predetermined minimum, power is applied to another battery, allowing the user to stably use the non-operating air conditioner operating unit 30.

That is, the battery power control manager 56 receives and monitors the charge amount information of the non-building air conditioner battery 31, etc. from each power monitoring unit, as described above, and transmits the monitoring information to the power controller 501.

In addition, the battery power control manager 56 receives charge information of the damper battery 12 from the damper battery power monitoring unit 535 connected to the damper battery connection unit 515 of the damper battery 35, and monitors the damper battery 35. ) monitors the state of charge and transmits the monitoring information to the power controller 501.

Accordingly, the power controller 501 monitors the predetermined minimum remaining charge status of each battery, stops applying power from the battery in use, and sends a control signal to apply the power from the other battery to the non-operating air conditioner operating unit 30. By transmitting it to the battery power control manager (56), stable operation of the no-start air conditioner operating unit (30) is achieved. Accordingly, preferably, through control of the power controller 501, each power may be controlled to be applied to the non-operating air conditioner operating unit 30 in the following order: non-operating air conditioner battery 31 -> damper battery 35. There will be, and the order of application of these batteries may be changed and used depending on the configuration of the vehicle being manufactured or design.

As an example, in a state where the power of the first charged no-drive air conditioner battery 31 is applied to the no-pass air conditioner operating unit 30 and operated, the remaining charge of the no-pass air conditioner battery 31 is set to a predetermined minimum. When it is determined that the remaining charge is remaining, the power controller 501 stops applying power to the non-starting air conditioner battery 31 and sends a control signal to allow power from the damper battery 35 to be applied to the non-starting air conditioner operating unit 30. It is transmitted to the battery power control manager (56). Accordingly, under the control of the battery power control manager 56, the output from the air conditioner battery connection unit 513 of the non-moving air conditioner battery 31 is stopped. In addition, power is applied from the damper battery connection part 515 of the damper battery 35 to the non-operational air conditioner power application unit 52, so that the non-operational air conditioner operating unit 30 operates with the power of the damper battery 35.

Next, the power controller 501, which has received information monitoring the remaining charge of the damper battery 35, determines that the remaining charge of the damper battery 35 is a predetermined minimum remaining charge of the damper battery 35. In this case, the power controller 501 transmits a control signal to stop the power output from the damper battery 35 to the battery power control manager 56.

Let's look at the control method of the non-starting air conditioning system 10 for both heating and cooling for commercial vehicles, which is operated at low power based on a heat pump according to the present invention prepared as described above.

First, a power generation monitoring step (S1) is performed in which the power generation status of the vehicle's engine generator (11) and solar power generation device (20) is monitored by the power generation power control manager (55) and the monitoring information is transmitted to the power controller (501). do.

That is, when the engine is running, power generation is being generated from the engine generator 11, and the power generation information from the engine generator 11 is transmitted to the power controller 501. In addition, since the solar power generator 20 is always generating power, information on the amount of power generation is transmitted.

In addition, since there is no power generation from the engine generator 11 when the engine is stopped, information on the amount of power generated by the solar power generation device 20 is transmitted to the power controller 501 through the power generation power control manager 55.

Next, in the power generation monitoring step (S1), when the vehicle's engine generator 11 is determined to be in a power generation state by the power controller 501, the power of the engine generator 11 is turned on under the control of the power controller 501. The engine power generation charging step (S2) is performed to charge the powerless air conditioner battery (31).

That is, when there is power generation from the engine generator 11 due to engine startup, the power generation power from the engine generator 11 charges the engine battery 12 and a portion of it charges the non-starting air conditioner battery 31.

In addition, in the power generation monitoring step (S1), when the vehicle's engine generator 11 is determined to be in a stopped state and the solar power generation device 20 is in a power generation state by the power controller 501, the power controller 501 A solar power generation charging step (S3) is performed in which the power generation power of the solar power generation device 20 is supplied through control and the non-moving air conditioner battery 31 is charged.

That is, the power generated by the solar power generation device 20 charges the non-moving air conditioner battery 31.

Accordingly, the engine power generation charging stage (S2) and the solar power generation charging stage (S3) may be performed in a different order depending on the design of a commercial vehicle or other vehicle, or the operation method of the vehicle.

Hereinafter, the detailed steps of the previously described power generation and charging stages will be described in more detail. First, the engine power generation charging step (S2), which is a charging process by the engine generator 11, transmits information on the amount of power generated by the engine generator 11 from the engine power generation power monitoring unit 531 connected to the engine power generation connection unit 511. An engine power generation monitoring step is performed in which information on the engine power generation status is received from the power generation power control manager (55) and transmitted to the power controller (501).

That is, as the engine starts, the power generated by the engine generator 11 is detected by the engine generated power monitoring unit 531 connected to the engine power generation connection unit 511, and transmitted to the engine generated power monitoring unit 531. Monitoring is performed by the engine power generation power monitoring unit 531 using this power generation information, and the power generation monitoring information of the engine generator 11 is transmitted to the power controller 501.

Next, if the engine power generation state is determined in this engine power generation monitoring step, power is supplied from the engine power generation connection unit 511 to the non-starting air conditioner battery 31 through the air conditioner battery connection unit 513 under the control of the power controller 501. The engine power generation battery charging step is performed by applying and charging.

And while charging the no-drive air conditioner battery 31 with the power of the engine generator 11 in the engine power generation battery charging step, the no-drive air conditioner battery is Engine power generation that receives the charging power amount information of (31) from the battery power control manager (56), analyzes the charging power amount from the non-moving air conditioner battery (31) in the battery power control manager (56), and determines the fully charged state. Perform the battery charge determination step.

Next, as a process in which the power generated by the solar power generation device 20 is charged, the solar power generation charging step (S3) is performed by the solar power generation power monitoring unit 534 connected to the solar power generation connection unit 514. A solar power generation monitoring step is performed in which information on the solar power generation status received from the power generation power control manager 55, which has received information on the amount of power generated from the solar power generation device 20, is transmitted to the power controller 501.

In addition, when the solar power generation status is determined in the solar power generation monitoring step, power is transferred from the solar power generation connection unit 514 to the non-starting air conditioner battery 31 through the air conditioner battery connection unit 513 under the control of the power controller 501. The solar power air conditioner battery charging step is performed by applying and charging.

Accordingly, while charging the non-moving air conditioner battery 31 with the power of the solar power generation device 20 in the solar power generation air conditioner battery charging step, the air conditioner battery power monitoring unit 533 connected to the air conditioner battery connection unit 513 Information on the charging power of the non-building air conditioner battery (31) is transmitted from the battery power control manager (56), and the battery power control manager (56) analyzes the charging power amount of the non-building air conditioning battery (31) to determine the fully charged state. A solar power air conditioner battery charge determination step is performed.

Next, in the power generation monitoring step (S1), when the power controller 501 determines that the vehicle's engine generator 11 is in a power generation state and the solar power generation device 20 is in a power generation state, the power controller ( While charging the non-starting air conditioner battery 31 by receiving power from the engine generator 11 under the control of 501, the generated power of the solar power generation device 20 is applied to the damper battery 35 to ) includes a solar power generation damper charging step (S4) that charges the

That is, in the solar power generation damper charging step (S4), which is a charging process for the damper battery 35, the power source generated by the engine generator 11 and the power source generated by the solar power generation device 20 are simultaneously charged. It is designed to be applied when generating power as a power source. Or, even when the engine stops and the engine generator 11 does not operate, even when the non-moving air conditioner battery 31 is fully charged by the solar power generation device 20, the solar power generation device 20 It will be possible to charge the damper battery 35 with the power provided.

In other words, the power source generated by the engine generator 11 is generated while the commercial vehicle is operating, and the power generated by the engine generator 11 when the engine is operated is generated during the operating process of the non-moving air conditioner operating unit 30. It will be used to charge the no-moving air conditioner battery 31, which is the main battery in .

On the other hand, even while charging the non-moving air conditioner battery 31 by the engine generator 11, the solar power generation device 20 continues to generate power, so during the power generation process by the engine generator 11, the solar power generation device ( The power generated by 20) is configured to be charged in the damper battery 35, which is a separate battery.

Therefore, the charging process for the damper battery 35 includes first determining whether or not the engine generator 11 is generating power, and then charging the damper battery 35 with the generated power from the solar power generation device 20. It will be performed. Alternatively, even in the case where there is no engine power generation, the charging process of the damper battery 35 can be performed by determining whether the idle air conditioner battery 31 is fully charged.

Looking at an embodiment of this step in detail, the solar power generation damper charging step (S4) is performed in the engine power generation power monitoring unit 531 connected to the engine power generation connection unit 511 of the engine generator 11. The power generation status information of the engine generator 11 is transmitted to the power generation power control manager 55, and the solar power generation power monitoring unit 534 connected to the solar power generation connection unit 514 of the solar power generation device 20 The power generation status information from the photovoltaic power generation device (20) is transmitted to the power generation power control manager (55), and the monitoring information on power generation from the engine generator (11) and the solar power generation device (20) is transmitted to the power generation power control manager (55). ) is transmitted to the power controller 501 to perform a solar power generation status determination step in which the power controller 501 determines the power generation status of the engine generator 11 and the solar power generation device 20.

In this way, in order to charge the damper battery 35 with power generation in the solar power generation status determination stage, power generation occurs in the engine generator 11 due to the operation of the engine of a commercial vehicle, and also power generation in the solar power generation device 20. It is determined whether this is happening or not.

In addition, in the solar power generation status determination step, the power generation status information of the engine generator 11 is sent to the power generation power control manager 55 in the engine power generation power monitoring unit 531 connected to the engine power generation connection unit 511 of the engine generator 11. ), and the monitoring information on the power generation from the engine generator 11 is transmitted from the power generation power control manager 55 to the power controller 501 to monitor the power generation status from the engine generator 11 from the power controller 501. This is to determine, or to determine a state in which the charging power of the no-start air conditioner battery (31) is applied to the no-start air conditioner operating unit (30) in a state where the engine generator (11) is not generating power.

That is, when the engine of a commercial vehicle is operated and power generation is generated from the engine generator 11, the power of the engine generator 11 charges the non-moving air conditioner battery 31. In this way, when the power generated from the engine generator 11 charges the non-moving air conditioner battery 31, the power generated from the solar power generation device 20 charges the damper battery 35, which is provided separately.

In addition, the no-start air conditioner operating unit 30 is operated when the commercial vehicle is not running. In particular, since the engine is stopped, there is no power generation from the engine generator 11. In this case, when operating the no-moving air conditioner operating unit 30, when operating the no-moving air conditioner operating unit 30 with the charging power of the no-moving air conditioner battery 31, the damper battery 35 and the solar power generation device As for (20), it is not involved in operating the no-moving air conditioner operating unit (30).

Therefore, when the engine is stopped and the non-starting air conditioner operating unit 30 is operated with power from the non-starting air conditioner battery 31, the generated power of the solar power generation device 20 is implemented to charge the damper battery 35. It could be. As a result, the power generation power of the solar power generation device 20, which generates power almost all the time, is constantly charged in the non-moving air conditioner battery 31 or the damper battery 35, thereby reducing the waste of the power generation power and the charging power charged in them. It is implemented so that it does not occur.

And under the control of the power controller 501 and the power generation power control manager 55, the air conditioner of the non-starting air conditioner battery 31 is connected to the engine power generation connection unit 511 of the engine generator 11 through the power generation power control manager 55. Power is applied to the battery connection part 513 to charge the non-moving air conditioner battery 31, and the damper battery connection part 515 of the damper battery 35 is connected to the solar power generation connection part 514 of the solar power generation device 20. A solar power generation damper battery charging step is performed in which power is applied to the side and the damper battery 35 is charged.

In other words, the charging process for the engine generator 11 can be carried out according to the engine power generation charging step (S2) described above. In the case where solar power generation is performed simultaneously with the engine power generation process separately, the solar power generation device 20 The power generation power is charged from the damper battery (35).

For example, in the case of the solar power generation charging step (S3) described above, it may be more useful when there is generally no power generation from the engine generator 11, while in the case of applying the damper battery 35, engine power generation and solar power If power generation proceeds simultaneously, the damper battery 35 is charged only for solar power generation.

During the charging of the non-starting air conditioner battery 31 by the engine generator 11 and the damper battery 35 by the solar power generation device 20, the air conditioner battery power monitoring unit connected to the air conditioner battery connection unit 513 From the damper battery power monitoring unit 535 connected to (533) and the damper battery connection unit 515, the battery power control manager 56 receives information on the charging power of the non-moving air conditioner battery 31 and the damper battery 35. , the battery power control manager 56 analyzes the amount of charging power in the non-moving air conditioner battery 31 and the damper battery 35, and performs a damper battery charge amount determination step to determine the fully charged state.

As a result, the charging power amount information about the charging power amount in the damper battery 35 is transmitted from the damper battery power monitoring unit 535 connected to the damper battery connection unit 515 to the battery power control manager 56, and the battery power control manager ( At 56), the charging of the damper battery 35 is monitored, and the monitoring information is transmitted to the power controller 501.

Next, the non-operational air conditioner operating unit 30 operates by receiving power from the non-operational air conditioner battery 31 under the control of the power controller 501. Perform the operation step (S5).

This no-start air conditioner operation operation step (S5) operates the no-start air conditioner operating unit 30 with the charging power of the no-start air conditioner battery 31, thereby enabling operation in a state where the engine of a commercial vehicle is stopped. It is said.

In general, commercial vehicles are equipped with a vehicle air conditioner that is operated by the power of the engine when the engine is started. In general, the vehicle's air conditioner according to the engine start, such as a compression process by engine power together with the power of the engine generator 11. The operation is performed.

On the other hand, since engine power cannot be used when the engine is stopped, a separate air conditioner for no-start operation is required, and in particular, a heat pump type air conditioner that can save energy is applied.

In this way, the operation of the air conditioner in the no-start state allows cooling or heating of the vehicle in the proposed space, such as the driver's seat.

In addition, in this non-operational air conditioner operation operation step (S5), the non-operational air conditioner operating unit 30 is operated with the charging power of the non-operational air conditioner battery 31, or further, with the charging power of the damper battery 35, which will be described later. This is to operate the no-moving air conditioner operating unit (30).

Looking at the detailed steps of the no-start air conditioner operation step (S5), the no-start air conditioner battery (31) is connected to the no-start air conditioner battery (31) from the air conditioner battery power monitoring unit (533) connected to the no-start air conditioner battery (31). The battery power control manager 56, which has received the charge amount of ), monitors each charge amount and performs a battery power monitoring step in which the monitoring information is transmitted to the power controller 501.

In addition, in the battery power monitoring step, the charge controller 501 operates the non-operating air conditioner battery 31 by using a battery whose charge is more than a predetermined operable charge amount that can operate the non-operating air conditioner operating unit 30. A non-moving air conditioner operating power selection step is performed to select the applied power of the unit 30.

Power is applied to the non-operating air conditioner operating unit 30 through the battery selected in the non-operating air conditioner operating power selection step above to operate it.

First, the no-start air conditioner operating unit 30 can be operated with the charging power of the no-start air conditioner battery 31 that has been charged by the solar power generation device 20 or the engine generator 11.

That is, in the step of selecting the operating power of the non-moving air conditioner, if the charge of the non-moving air conditioner battery (31) is greater than the predetermined operational charge amount that can operate the non-moving air conditioner operating unit (30), the power of the non-moving air conditioner battery (31) is turned on. The operation step of applying the power to the remote air conditioner battery to the remote air conditioner operating unit 30 is performed.

Looking at the detailed steps of the no-start air conditioner battery power application operation step for the operation of the no-start air conditioner operating unit 30 by application of the charging power of the no-start air conditioner battery 31, the no-start air conditioner battery 31 ) If the charge amount is more than the predetermined operable charge that can operate the non-operating air conditioner operating unit 30, the power of the non-operating air conditioner battery 31 is controlled by the power controller 501 to the air conditioner battery connection unit 513. A step of applying the passive air conditioner battery power to the passive air conditioner power application unit 52 of the passive air conditioner operating unit 30 is performed.

In other words, it is checked whether the charging power charged in the no-start air conditioner battery (31) is sufficient to operate the no-start air conditioner operating unit (30), and whether a certain amount of operation is possible to operate the no-start air conditioner operating unit (30). The set value of the charge amount is read from the control memory 502, and the remaining charge of the non-moving air conditioner battery 31 is compared with the predetermined operable charge amount read, and a control signal for application of charging power is transmitted.

Therefore, under the control of the power controller 501 and the battery power control manager 56, the power of the non-moving air conditioner battery (31) is applied to the non-moving air conditioner operating unit (30) through the non-moving air conditioner power application unit (52). .

Next, a no-start air conditioner battery power operation step is performed in which the no-pass air conditioner operating unit 30, which receives power from the no-pass air conditioner battery 31 through the no-pass air conditioner power application unit 52, operates. Thus, cooling and heating are performed on the driver's seat of the commercial vehicle where the user is located.

In this way, while the no-start air conditioner operating unit (30) is operated with the power of the no-start air conditioner battery (31), the remaining charge of the no-start air conditioner battery (31) is monitored by the air conditioner battery power monitoring unit (533) connected to the air conditioner battery connection unit (513). A non-moving air conditioner battery charge remaining monitoring step is performed to monitor and transmit to the battery power control manager (56).

Accordingly, the amount of charge consumed by the no-moving air conditioner battery 31 is monitored.

Afterwards, in the battery power control manager 56, which has received monitoring information on the remaining charge of the no-start air conditioner battery 31 from the air conditioner battery power monitoring unit 533, the remaining charge of the no-start air conditioner battery 31 is determined to be a predetermined minimum charge. When it is determined by the remaining amount, the non-starting air conditioner battery operation stop step is performed to stop the power supply from the no-start air conditioner battery (31) to the no-start air conditioner operating unit (30) and stop the operation of the no-start air conditioner operating unit (30). It is to carry out.

In this no-start air conditioner battery operation stop step, the operation of the no-start air conditioner operating unit 30 by the no-start air conditioner battery 31 is temporarily stopped, and then the damper battery 35, etc., is charged with sufficient power using another battery. Once determined, the power of the battery will be applied to the non-operating air conditioner operating unit 30 and the non-operating air conditioner 30 will continue to operate.

Next, when the generated power of the solar power generation device 20 is charged in the damper battery 35 provided together, the charging power of the damper battery 35 can be used as a power source to operate the non-starting air conditioner operating unit 30. will be.

That is, when the damper battery 35 is charged with the generated power of the solar power generation device 20, the damper battery power application operation step in which the non-starting air conditioner operating unit 30 is operated by receiving power from the damper battery 35. It includes (S6).

For this purpose, in the battery power monitoring step described above, the battery power control manager receives charge information of the damper battery 35 from the damper battery power monitoring unit 535 connected to the damper battery connection unit 515 of the damper battery 35. At (56), the charge amount of the damper battery (35) can be monitored and the monitoring information can be transmitted to the power controller (501).

Through this monitoring process, in the non-operating air conditioner operating power selection step, in the battery power monitoring step, the charge amount of the damper battery 35 is greater than or equal to a predetermined operable charge that can operate the non-operating air conditioner operating unit 30. In this case, the power controller 501 selects the charging power of the damper battery 35 as the applied power to the non-starting air conditioner operating unit 30.

In this way, as a process of applying the charging power of the damper battery 35 to the operating power of the non-operational air conditioner operating unit 30, the damper battery power application operation step (S6) first determines the charge level of the damper battery 35 to the non-operational air conditioner operation unit 30. When the predetermined operational charge amount for operating the air conditioner operating unit 30 is higher, the power of the damper battery 35 is transferred from the damper battery connection unit 515 to the non-starting air conditioner operating unit 30 under the control of the power controller 501. ) perform the damper battery power application step of applying to the non-moving air conditioner power application unit 52.

And, by performing the damper battery power operation step in which the non-operational air conditioner operating unit 30, which receives power from the damper battery 35 through the non-operational air conditioner power application unit 52, operates, the non-operational air conditioner operating unit 30 It operates with the charging power of the damper battery (35).

In this way, while the silent air conditioner operating unit 30 is operated with the power of the damper battery 35, the damper battery power monitoring unit 535 connected to the damper battery connection unit 515 monitors the remaining charge of the damper battery 35 and monitors the remaining charge of the damper battery 35. The damper battery charge remaining charge monitoring step is performed, which is transmitted to the power control manager (56).

Therefore, it will be determined whether charging power is consumed by monitoring the remaining charge of the damper battery 35.

Afterwards, the battery power control manager 56, which received the monitoring information of the remaining charge of the damper battery 35 from the damper battery power monitoring unit 535, determines that the remaining charge of the damper battery 35 is a predetermined minimum remaining charge. In this case, the damper battery operation stop step is performed to stop the power supply from the damper battery 35 to the non-starting air conditioner operating unit 30 and stop the operation of the non-starting air conditioner operating unit 30.

As described above, in a situation where power generation is made from the solar power generation device 20 in addition to the engine generator 11, the non-operating air conditioner battery 31, which is the main battery power source for operating the non-operating air conditioner operating unit 30, While the power generated by the engine generator 11 generated by the engine of the commercial vehicle is charged, the power generated by the solar power generation device 20 that is simultaneously generated is charged in a separately provided damper battery 35.

In general, power generation in the solar power generation device 20 is generated by solar cell panels using sunlight, and low-power generated power is collected from the cells of each panel and charged. In general, the amount of charge flows in a stable charging pattern with direct current power.

On the other hand, the engine generator 11, which generates power by operating engine power, converts high-rpm alternating current electricity into direct current, and therefore forms a charging source with an irregular waveform in each minute section.

If each battery or charging circuit is formed separately, no problems will occur, but the situation where charging power from different power sources charges one battery may not be correct.

Accordingly, in the case of the solar power generation device 20, if light is irradiated from the outside, power can be generated even slightly.

On the other hand, the engine generator 11 generates power only when the engine is started, and does not generate power when the vehicle engine is stopped.

However, although the engine generator 11 is charged first to the engine battery 12, the engine generator 11 forms a charging source of great intensity because it is powered by engine power, which is a large power source, and therefore the non-moving air conditioner battery 31 ) is in a useful state for charging.

Therefore, when the engine is stopped, the power generated from the solar power generation device 20 charges the non-starting air conditioner battery 31, while when the engine is started, the power generated from the engine generator 11 charges the non-starting air conditioner battery. While charging (31), the power generation power of the solar power generation device (20) is provided to charge a separate damper battery (35), thereby increasing charging efficiency by achieving a maximum charging state.

As described above, the battery power control manager 56 continuously monitors the remaining charge of each battery during operation of the remote air conditioner operating unit 30, and transmits the monitoring information to the power controller 501. , the power controller 501 stops applying power to each battery when the remaining charge value decreases compared to the predetermined minimum remaining charge amount setting value for each battery.
