Description

Power supply control system for air conditioners with photovoltaic power generation for commercial vehicles

The present invention relates to an air conditioner for commercial vehicles, and more particularly, to a non-dong air conditioner for both cooling and heating for commercial vehicles driven by low power based on a heat pump, when the operation of commercial vehicles such as trucks or special vehicles in addition to passenger cars is stopped, the vehicle's battery It is to operate an air conditioner driven with low power based on a heat pump that receives power from a battery installed in a commercial vehicle without starting using electric power. The present invention relates to a power supply control system for an air conditioner equipped with photovoltaic power generation for a commercial vehicle equipped to increase charging efficiency by charging a generator using a generator as an energy source.

In general, commercial vehicles, including trucks, start their engines by burning fuel such as diesel, gasoline, or gas, and drive the vehicle through such engine start-up.

As such, the electricity required during operation of the commercial vehicle is supplied from the generator of the vehicle 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, the driver can safely operate the commercial vehicle.

In general, among commercial vehicles, trucks usually carry cargo and drive long distances at night, and sleep in the space behind the driver's seat while parked in a place such as a rest area during night driving. In this case, you need to cool off in the summer and warm up in the winter so you can rest comfortably.

However, there is a problem in that it is difficult to operate the electric appliances because it is difficult to receive electricity from the generator of the engine because long-term idling is prohibited according to related regulations.

Therefore, it is necessary to provide an environment where electric appliances can be used without starting the engine of a commercial vehicle such as a truck, so that a person can rest comfortably.

In addition, recently, as vehicles are used for camping, camping vehicles operate electric appliances using a vehicle battery while the engine is stopped. However, since the battery of a vehicle generally has a limited capacity to be used when the vehicle engine is started, there is a concern that the battery may be rapidly consumed when other electric appliances are used without the engine running. Therefore, in the case of camping, there is a disadvantage in that a separate auxiliary battery is used.

As such, it is necessary to have a technical configuration capable of stably receiving power over a long period of time without power supply from an engine generator in a commercial vehicle such as a truck or a camping vehicle.

In addition, technical proposals for charging and power supply systems are urgently required to enable optimal power operation through vehicle battery power.

In particular, in the case of the engine battery 12, since the power of the engine battery 12 must be used to start the vehicle engine again when the vehicle is stopped and the engine is stopped, all charging power of the air conditioner 30 is ignored. cannot be used for operation. In addition, even if the vehicle's black box or other vehicles are stopped or parked, since the power required for the vehicle is basically required, a predetermined minimum remaining charge for driving such a vehicle must remain.

The air conditioner battery 31 is charged.

In addition, since there is no engine operation when the vehicle is not running, no power is generated from the engine generator 11, whereas power is generated from the photovoltaic device 20, so the sun connected to the photovoltaic power generation connector 514 The photovoltaic power monitoring unit 534 forwards the photovoltaic power generation information to the generation power control manager 55, whereby the photovoltaic power generation connection unit 514 is controlled by the power controller 501 and the generation power control manager 55. ) to be charged to the air conditioner battery 31 through the air conditioner battery connection part 513.

In addition, when the user operates the air conditioner while driving the vehicle, the air conditioner of the vehicle basically installed in the vehicle is operated.

On the other hand, when the vehicle is not operated, the engine generator 11 does not generate electricity, so the air conditioner of the vehicle cannot be operated.

Therefore, the user can operate the heavy-duty air conditioner 30 to use cool wind in the hot season and warm wind in the cold season.

In order to operate the non-moving air conditioner 30 as described above, the non-moving air conditioner 30 is operated by using the charging power of the non-moving air conditioner battery 31 that has been pre-charged. That is, under the control of the power controller 501 and the battery power control manager 56, etc., the air conditioner battery connection part 513 of the non-active air conditioner battery 31 passes through the non-active air conditioner power supply unit 52 to the non-active air conditioner 30. ) to supply power.

If it is determined that, the power controller 501 stops supplying power from the non-active air conditioner battery 31 and transmits a control signal so that power from the damper battery 35 is applied to the non-active air conditioner 30 to the battery power control manager Send to (56). Thus, under the control of the battery power control manager 56, the output of the idle air conditioner battery 31 from the air conditioner battery connection unit 513 is stopped. In addition, power is applied from the damper battery connection part 515 of the damper battery 35 to the non-current air conditioner power applying part 52, so that the non-current air conditioner 30 operates with the power of the damper battery 35.

Next, the remaining charge of the damper battery 35 is determined as a predetermined minimum charge remaining amount in the damper battery 35 by the power controller 501 receiving the information for monitoring the remaining charge of the damper battery 35 In this case, the power controller 501 stops the power output from the damper battery 35, and sends a control signal for the power of the engine battery 12 to be applied to the non-moving air conditioner 30 side to the battery power control manager 56 send to

Accordingly, under the control of the battery power control manager 56, the output of the damper battery 35 from the damper battery connection unit 515 is stopped. And, when the power of the engine battery 12 corresponds to an operable charge amount capable of operating the non-moving air conditioner 30, the engine battery connection part 512 of the engine battery 12 moves to the non-moving air conditioner power application part 52 side. that power is applied.

A solar power generation air conditioner battery charging amount determination step (S33) for determining the state of charge is performed.

Next, with the operation of the non-moving air conditioner 30, the non-moving air conditioner 30 is operated by receiving power from the engine battery 12 or the non-moving air conditioner battery 31 under the control of the power controller 501 Operation step (S6) is carried out.

In addition, in the battery power monitoring step (S61), the charge controller 501 determines the charge amount of the engine battery 12 and the non-moving air conditioner battery 31 to operate the non-moving air conditioner 30. A non-moving air conditioner operating power selection step (S62) of selecting a battery having an abnormality as the applied power of the non-moving air conditioner 30 is performed.

Power is applied to the non-active air conditioner 30 through the battery selected by the non-active air conditioner operating power selection step (S62) to operate it.

First, the non-moving air conditioner 30 can be operated with the charging power of the non-moving air conditioner battery 31 charged by the photovoltaic device 20 or the engine generator 11.

That is, in the non-active air conditioner operating power selection step (S62), if the charge amount of the non-active air conditioner battery (31) is greater than a predetermined operable charge amount capable of operating the non-active air conditioner (30), the power source of the non-active air conditioner battery (31) It is to perform the non-dong air conditioner battery power application operation step (S63) of applying the non-dong air conditioner to the non-dong air conditioner 30.

Looking at the detailed steps of the non-moving air conditioner battery power application operation step (S63) for the operation of the non-moving air conditioner 30 by applying the charging power of the non-moving air conditioner battery 31, the non-moving air conditioner battery ( 31) When the charge amount of the non-active air conditioner (30) is greater than the predetermined operable charge amount, the power of the non-active air conditioner battery (31) is switched from the air conditioner battery connection part (513) under the control of the power controller (501). [0040] A step of applying power to the non-active air conditioner battery to the non-active air conditioner power application unit 52 of the non-active air conditioner 30 (S631) is performed.

That is, it is checked whether or not the charging power charged in the non-moving air conditioner battery 31 is sufficient to operate the non-moving air conditioner 30, and the set value of a predetermined operable charge amount capable of operating the non-moving air conditioner 30. is read from the control memory 502, and the remaining charge amount of the air conditioner battery 31 is compared with the read predetermined operable charge amount, and a control signal for applying charging power is transmitted.

Thus, under the control of the power controller 501 and the battery power control manager 56, the power of the non-active air conditioner battery 31 is applied to the non-active air conditioner 30 through the non-active air conditioner power application unit 52.

Next, the non-active air conditioner battery power operation step (S632) is performed in which the non-active air conditioner 30 receiving power from the non-active air conditioner battery 31 through the non-active air conditioner power application unit 52 operates. Thus, the cooling and heating operation is performed for the driver's seat of the commercial vehicle where the user is located.

In this way, while the non-active air conditioner 30 is operating with the power of the non-active air conditioner battery 31, the remaining charge of the non-active air conditioner battery 31 is monitored by the air conditioner battery power monitoring unit 533 connected to the air conditioner battery connection part 513. Then, the air conditioner battery charge remaining amount monitoring step (S633) is performed, which is transmitted to the battery power control manager 56.

Thus, the amount of charge of the consumed copper air conditioner battery 31 is monitored.

Then, in the battery power control manager 56 that receives the monitoring information of the remaining charge of the non-operating air conditioner battery 31 from the air conditioner battery power monitoring unit 533, the remaining charge of the non-operating air conditioner battery 31 is charged to a predetermined minimum level. If it is determined by the remaining amount, the non-moving air conditioner battery operation stop step (S634) is performed to stop the application of power from the non-moving air conditioner battery 31 to the non-moving air conditioner 30 and to stop the operation of the non-moving air conditioner 30. is to do

In this non-moving air conditioner battery operation stop step (S634), the operation of the non-moving air conditioner 30 by the non-moving air conditioner battery 31 is temporarily stopped, and then, as another battery, the engine battery 12 or the damper battery described later If it is determined that the charging power is sufficient in (35), etc., the power of the corresponding battery is applied to the neglected air conditioner 30, and the neglected air conditioner 30 continues to operate.

That is, in the step described above, when the charge amount of the engine battery 12 in the non-active air conditioner operating power selection step (S62) is equal to or greater than a predetermined operable charge amount capable of operating the non-active air conditioner 30, the engine battery 12 An engine battery power application operation step (S64) for applying power to the non-moving air conditioner 30 is performed.

As such, the non-moving air conditioner 30 can be operated with the power of the engine battery 12, and the detailed steps of the engine battery power application operation step (S64) are as follows.

That is, when the charge amount of the engine battery 12 is equal to or greater than the predetermined operable charge amount capable of operating the non-moving air conditioner 30, the power of the engine battery 12 is switched to the engine battery connection part 512 under the control of the power controller 501. ) performs an engine battery power application step (S641) for applying power to the non-moving air conditioner power applying unit 52 of the non-moving air conditioner 30.

Accordingly, in the case of the engine battery 12, since the engine is stopped and the air conditioner 30 is operated, the amount of power consumed to start the engine again later and the amount of power used for the black box or other devices of the commercial vehicle In a sufficiently secured state, the remaining charging power is used to operate the silent air conditioner (30).

Therefore, the set value of the predetermined operable charge amount for the engine battery 12 stored in the control memory 502 will be a charge remaining much larger than the operable charge amount in other batteries, and detailed set values for this are commercially available. It will be determined by the specifications of the vehicle, electric components installed in the commercial vehicle, and the specifications of the air conditioner 30.

As such, when the remaining charge of the engine battery 12 corresponds to a predetermined operable charge amount, power is applied under the control of the power controller 501 .

Then, an engine battery power supply operation step (S642) is performed in which the non-active air conditioner 30 receiving power from the engine battery 12 through the non-active air conditioner power application unit 52 operates.

Then, while the non-moving air conditioner 30 is operated with the power of the engine battery 12, the engine battery power monitoring unit 532 connected to the engine battery connection unit 512 monitors the remaining charge of the engine battery 12 to control battery power. The engine battery charge remaining amount monitoring step (S643) transmitted to the manager 56 is performed.

That is, while the non-moving air conditioner 30 is operating, the remaining charge in the engine battery 12 is continuously monitored, and the remaining charge of the engine battery 12 is sufficient to start the engine or operate other electrical components. We will continue to monitor whether

In addition, the battery power control manager 56 receiving the monitoring information of the remaining charge of the engine battery 12 from the engine battery power monitoring unit 532 determines the remaining charge of the engine battery 12 as a predetermined minimum remaining charge. In this case, an engine battery operation stop step (S644) of stopping power supply from the engine battery 12 to the non-active air conditioner 30 and stopping the operation of the non-active air conditioner 30 is performed.

That is, the remaining charge of the engine battery 12 is sufficient to start the engine or operate other electrical components of the commercial vehicle, and is a predetermined minimum remaining charge, which will be greater than the minimum remaining charge of the other batteries.

As such, the remaining charge of the engine battery 12 is determined by the power controller 501 reading the set value data of the predetermined minimum remaining charge corresponding to the engine battery 12 from the control memory 502, and When the remaining amount of charge reaches a predetermined minimum level due to consumption, control is performed so that no more power is applied to the idle air conditioner 30 .

As described above, the battery power control manager 56 continuously monitors the remaining charge amount of each battery during operation of the non-moving air conditioner 30, transmits the monitoring information to the power controller 501, and transmits the power The controller 501 compares each battery with a predetermined minimum remaining charge level setting value, and stops supplying power to each battery when the level of charge level decreases.

When it is determined that the application of power to all batteries including the damper battery to be described later is terminated, the power controller 501 terminates the operation of the idle air conditioner 30 .

That is, when the battery power control manager 56 monitors the remaining charge of the engine battery 12 and the idle air conditioner battery 31 to each predetermined minimum charge, the power controller receives the monitoring information of the batteries. Under the control of step 501, the non-active air conditioner operation stop step (S7) of stopping power supply from the engine battery 12 and the non-active air conditioner battery 31 to the non-active air conditioner 30 is performed.

In addition, the non-moving air conditioner operation stop step (S7) includes the case of termination due to power consumption of the damper battery 35 described later, and when it is determined that all battery power is consumed, the operation of the non-moving air conditioner 30 is stopped will be.

Next, in addition to the engine battery 12 and the heavy-duty air conditioner battery 31, the damper battery 35 additionally configured to act as a damper, and charging the damper battery 35 and damper battery 35 power Let's take a look at the operation process of the Mushi-dong air conditioner (30).

Accordingly, in the power generation monitoring step (S1), when it is determined by the power controller 501 that the engine generator 11 of the vehicle is in a power generation state and the photovoltaic device 20 is in a power generation state, the power controller 501 ) While receiving power from the engine generator 11 and charging the air conditioner battery 31 under the control of ), the generated power of the photovoltaic power generation device 20 is applied to the damper battery 35 side, and the damper battery 35 It includes a solar power generation damper charging step (S4) for charging.

That is, the solar power generation damper charging step (S4), which is a charging process for the damper battery 35 and the damper battery 35, generates power by the solar power generation device 20 together with the power source generated by the engine generator 11 This is a configuration to be applied when a power source or the like is simultaneously generating power as a charging power source.

That is, the power source generated by the engine generator 11 is generated while the commercial vehicle is running, and the power generated by the engine generator 11 generated when the engine operates is It will be used to charge the main battery, the air conditioner battery 31.

On the other hand, since the solar power generation device 20 continues to generate power even during the charging of the air conditioner battery 31 by the engine generator 11, 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, in the charging process for the damper battery 35, first, it is determined whether or not the engine generator 11 generates power, and then the damper battery 35 is charged with the power generated by the photovoltaic device 20. it will be done

Looking more closely at these steps, the photovoltaic damper charging step (S4) is the engine generator 11 in the engine generator power monitor 531 connected to the engine generator connection 511 of the engine generator 11. The power generation status information is transmitted to the power generation power control manager 55, and the photovoltaic power generation power monitoring unit 534 connected to the solar power generation connection unit 514 of the solar power generation device 20 solar power generation device 20 ) transmits power generation status information to the power generation power control manager 55, and monitors information on power generation from the engine generator 11 and the photovoltaic power generation device 20 from the power generation power control manager 55 to the power controller ( 501), and the power controller 501 performs a photovoltaic power generation state determination step (S41) of determining the power generation states of the engine generator 11 and the photovoltaic device 20.

As such, in the solar power generation state determination step (S41), to charge the power generation power to the damper battery 35, while there is power generation in the engine generator 11 due to the engine operation of the commercial vehicle, and also the solar power generation device 20 ), it is also determined whether or not development is taking place.

In addition, in the photovoltaic power generation state determination step (S41), the engine power generation power monitoring unit 531 connected to the engine power generation connection unit 511 of the engine generator 11 controls the power generation state information of the engine generator 11. manager 55, and the monitoring information on power generation in the engine generator 11 is transmitted from the power generation power control manager 55 to the power controller 501, and the power controller 501 transmits It is to determine the state of power generation, or to determine the state in which the charging power of the non-moving air conditioner battery 31 or the engine battery 12 is applied to the non-moving air conditioner 30 in a state where the engine generator 11 does not generate power.

That is, when the engine of the commercial vehicle is operated and power is generated in the engine generator 11, the power of the engine generator 11 charges the idle air conditioner battery 31. In this way, when the power generated by the engine generator 11 charges the secondary copper air conditioner battery 31, the power generated by the photovoltaic device 20 charges the separately provided damper battery 35.

In addition, the heavy-duty air conditioner 30 is operated when the commercial vehicle is not running, and in particular, since the engine is stopped, the engine generator 11 does not generate power. In this case, in operating the non-moving air conditioner 30, when the non-moving air conditioner 30 is operated with the charging power of the non-moving air conditioner battery 31 or the charging power of the engine battery 12, the damper battery 35 ) and the photovoltaic device 20 are not involved in operating the air conditioner 30.

Therefore, in a state in which the engine is stopped, when the heavy copper air conditioner 30 is operated with the power of the heavy copper air conditioner battery 31 and the engine battery 12, the power generated by the solar power generation device 20 is supplied to the damper battery 35 It will be able to be implemented to charge. As a result, the generated power of the photovoltaic power generation device 20, which generates electricity almost always, is always charged in the non-dong air conditioner battery 31 or the damper battery 35, so that the waste of the generated power and the charging power charged in them is reduced. It will be implemented so that there is no

And, through the power generation power control manager 55 under the control of the power controller 501 and the power generation power control manager 55, the air conditioner of the non-moving air conditioner battery 31 at the engine power generation connection part 511 of the engine generator 11. Power is applied to the battery connection part 513 so that the idle air conditioner battery 31 is charged, and the damper battery connection part 515 of the damper battery 35 in the photovoltaic power generation connection part 514 of the solar power generation device 20 A photovoltaic power generation damper battery charging step (S42) in which power is applied to the side and the damper battery 35 is charged is performed.

That is, the charging process for the engine generator 11 may proceed according to the engine power generation charging step (S2) described above, and in the case where there is a separate engine power generation process and solar power generation is performed together, The generated power of is to be charged in the damper battery (35).

For example, in the case of the solar power generation charging step (S3) described above, it can be more useful when there is no power generation of the engine generator 11, whereas in the case of applying such a damper battery 35, engine power generation and solar power When the power generation proceeds together, the damper battery 35 is charged only for solar power generation.

During the charging of the idle air conditioner battery 31 by the engine generator 11 and the charging of the damper battery 35 by the photovoltaic device 20, the air conditioner battery power monitoring unit connected to the air conditioner battery connection unit 513 533 and the damper battery power monitoring unit 535 connected to the damper battery connection unit 515 receives information on the charging power of the air conditioner battery 31 and the damper battery 35 from the battery power control manager 56 , The battery power control manager 56 analyzes the amount of charged power in the idle air conditioner battery 31 and the damper battery 35, and performs a damper battery charge amount determination step (S43) to determine the fully charged state.

As a result, the damper battery power monitoring unit 535 connected to the damper battery connection unit 515 transmits the information on the amount of energy charged in the damper battery 35 to the battery power control manager 56, and the battery power control manager ( In step 56, the charging of the damper battery 35 is monitored, and the monitoring information is transmitted to the power controller 501.

In this way, when the damper battery 35 is charged with the power generated by the photovoltaic device 20, the charging power of the damper battery 35 is used as a power source for operating the air conditioner 30.

That is, in the non-moving air conditioner operation step (S6), when the damper battery 35 is charged with the generated power of the photovoltaic device 20, the non-moving air conditioner 30 receives power from the damper battery 35 It includes a damper battery power application operation step (S65) in which is operated.

To this end, in the battery power monitoring step (S61) described above, the damper battery power monitoring unit 535 connected to the damper battery connection unit 515 of the damper battery 35 receives the charge amount information of the damper battery 35. The power control manager 56 monitors the charge amount of the damper battery 35 and transmits monitoring information to the power controller 501.

In this way, by the monitoring process, in the non-active air conditioner operation power selection step (S62), in the battery power monitoring step (S61), the charged amount of the damper battery 35 determines a predetermined amount capable of operating the non-active air conditioner 30. If it is more than the operable charge amount, the charging power of the damper battery 35 in the power controller 501 is selected as the applied power of the non-moving air conditioner 30.

As such, as a process of applying the charging power of the damper battery 35 as the operating power of the non-active air conditioner 30, in the damper battery power application operation step (S65), first, the amount of charge of the damper battery 35 is non-active air conditioner ( 30), the power of the damper battery 35 is transferred from the damper battery connection part 515 under the control of the power controller 501 to the non-operating air conditioner power of the non-operating air conditioner 30 A damper battery power application step (S651) applied to the application unit 52 is performed.

Then, a damper battery power operation step (S652) is performed in which the non-active air conditioner 30 supplied with power from the damper battery 35 through the non-active air conditioner power application unit 52 operates, so that the non-active air conditioner 30 The damper battery 35 is operated as a charging power source.

While the air conditioner 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 to control battery power The damper battery charge remaining amount monitoring step (S653) transmitted to the manager 56 is performed.

Therefore, by monitoring the remaining charge of the damper battery 35, it will be determined whether or not the charging power is consumed.

Thereafter, the battery power control manager 56, which receives the monitoring information of the remaining charge of the damper battery 35 from the damper battery power monitoring unit 535, determines the remaining charge of the damper battery 35 as a predetermined minimum remaining charge. In this case, the application of power from the damper battery 35 to the non-active air conditioner 30 is stopped and the damper battery operation stop step (S654) of stopping the operation of the non-active air conditioner 30 is performed.

In the subsequent process, when other battery power such as the engine battery 12 or the non-moving air conditioner battery 31 is also consumed, the non-moving air conditioner 30 is completely stopped by the non-moving air conditioner operation stop step (S7). It will be.

In addition to the engine generator 11 as described above, in a situation where power is generated from the photovoltaic power generation device 20, the non-active air conditioner battery 31, which is the main battery power source for operating the non-active air conditioner 30, commercial vehicles While the power generated by the engine generator 11 is charged by the engine of the engine, the power generated by the photovoltaic device 20 is charged to the damper battery 35 provided separately.

In general, power generation in the photovoltaic device 20 is by solar cell panels using sunlight, and the cells of each panel collect and charge the power generated at low power. In general, the charge amount of a stable charging pattern flows with a DC power supply.

On the other hand, the engine generator 11, which generates electricity by operating engine power, converts alternating current generated by high rotation into direct current, so it forms a charging source with irregular waveforms for each fine section.

If each separate battery or charging circuit is formed, no particular problem will occur, but a situation in which charging power from different power sources charges one battery may not be correct.

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

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 in the engine battery 12, in the engine generator 11, since it is caused by the engine power, which is a large power source, it forms a high-intensity charging source, and thus the non-moving air conditioner battery (31 ) to be in a useful state for charging.

Therefore, when the engine is stopped, power generated by the photovoltaic device 20 charges the non-moving air conditioner battery 31, whereas when the engine is started, power generated by the engine generator 11 is non-moving air conditioner battery. 31 is charged, and a separate damper battery 35 is provided to charge the generated power of the photovoltaic device 20, thereby increasing the charging efficiency, such as achieving a maximum charged state.

Although the embodiments of the present invention have been described in detail above, this is because an embodiment has been described so that those skilled in the art can easily practice the present invention. The technical idea of the present invention should not be construed as being limited.
