Specifically, the camper load 50 may mean at least one light, a ventilator, a copper heater, a sewage device, a water purifying device, and a water supply device provided in the camper.

In addition, such a camper load 50 can be classified into a basic load which is essential for driving and a user of the camper and has high importance and an optional load that is selectively used by the user and has low importance.

The first battery 110 may mean a battery directly involved in starting the camper.

The power management processor 200 may distribute power supplied by the second battery 120 .

That is, the power management processor 200 may refer to a processor that controls the power supplied by the second battery 120 to the camper load.

The central processor 300 may mean a processor that comprehensively controls the camper.

The central processor 300 may form the user's power usage log information by accumulating data that matches the power information of the first battery 110 and the second battery 120 with at least the power consumption of the camper load.

The user's log information means information obtained by learning the power usage pattern of the camper user, and the camper can continuously learn power information and power consumption of the battery.

In addition, the central processor 300 may use the learned data to form power use log information based on the user's frequency of load use, and the like.

Meanwhile, the central processor 300 may predict a real-time simulation report corresponding to the current driving situation using a plurality of reference simulation reports based on the similarity between the current driving situation of the camper and the reference driving situation of the camper and the usage log information. .

That is, the central processor may first determine the similarity between the current driving situation of the vehicle and the reference driving situation, and then change the reference simulation report with high similarity to predict a real-time simulation report that can correspond to the current camping car.

Meanwhile, when the central processor 300 predicts a real-time simulation report, log information derived earlier may be used together.

Meanwhile, the power management processor 200 may control the second battery to supply optimized power to the camper load based on the real-time simulation report derived by the above-described method.

Meanwhile, the plurality of reference simulation reports may include the remaining power supply time of the second battery 120 based on the relationship between the voltage and current of the second battery 120 .

That is, each reference simulation report may mean data on battery usage time corresponding to the battery condition of the camper corresponding to each reference driving condition. In more detail, the simulation report may mean a value in which the output voltage of the battery and the battery usage time are matched.

The central processor 300 interpolates at least two of a plurality of reference simulations among a plurality of reference simulation reports based on the similarity between the current driving situation of the camper and the reference driving situation of the camper and the use log information to provide a real-time simulation report predictable.

While the camper can perform driving at different speeds and different types of loads, it is difficult to determine that the current driving situation of the vehicle corresponds to all of the reference simulation data because predetermined reference simulation data is limited.

Meanwhile, the central processor 300 may interpolate two reference simulation reports in predicting such a real-time simulation report.

Meanwhile, each of the plurality of reference simulation reports may be determined differently depending on whether the camper is charged, whether the camper is driven, and whether the electric power of the camper load is used. A detailed description related thereto will be given later.

On the other hand, the power management processor 200, when the voltage of the second battery is less than the predetermined voltage, preferentially supplies power to the basic load among the camper loads, and supplies the minimum power required for driving to optional loads other than the basic load. . In this way, the power management processor can perform optimal power control by distributing power to each load.

Meanwhile, the power management processor 200 may provide a maximum remaining power supply time corresponding to the current driving of the camper by distributing power to the basic load and the optional load.

That is, the fact that the current camper is driven the maximum time means that the power control of the camper is most efficiently performed.

The power management processor 200 may perform optimized power control by distributing appropriate power to a basic load and an optional load.

Meanwhile, the central processor 300 may determine the remaining power supply time of the camper by matching the output current and output voltage of the second battery to the reference simulation report having the highest similarity to the current driving situation.

As described above, the central processor 300 may predict a real-time simulation report corresponding to the current driving situation using the reference simulation report and determine the remaining power supply time accordingly.

However, even without such calculation, the central processor may determine a reference driving situation most similar to the current driving situation of the vehicle and determine a reference simulation report corresponding to the reference driving situation.

The central processor may derive the remaining power supply time of the camper by matching the current and voltage of the second battery to the reference simulation report.

On the other hand, the software structure 10 described in FIG. 2 is only an embodiment of the software structure used by the central processor, and there is no limitation of the software structure in which the camper learns the user's pattern.

3 is a table showing the driving situation of the camper corresponding to the reference simulation report according to an embodiment.

FIG. 4 is a graph illustrating the reference simulation report corresponding to FIG. 3 in relation to the voltage and time of the battery.

Referring to FIG. 3 , the central processor may form a plurality of reference simulation reports including the remaining power supply time of the camper based on the reference driving condition of the camper.

In the case of CASE1 disclosed in FIG. 3, without external charging, charging of the battery due to driving does not occur, and shows a reference driving situation in which the camper load uses the maximum current. In CASE1, the camper load uses the maximum current of 70A.

In a driving situation such as CASE1, the central processor may form a reference simulation report such as C41 of FIG. 4 .

That is, the central processor can determine the time it takes to be discharged in the case of CASE1. In case of CASE1, the time it takes to discharge, that is, the remaining power supply time may be determined to be 100 minutes.

In the case of CASE 2 disclosed in FIG. 3, without external charging, charging of the first battery occurs due to 80 km/h driving and shows a reference driving situation in which the camper load uses the maximum current. In CASE2, the camper load uses the maximum current of 70A.

In a driving situation such as CASE2, the central processor may form a reference simulation report such as C42 of FIG. 4 .

That is, the central processor can determine the time it takes to be discharged in the case of CASE2. In case of CASE2, the time it takes to discharge, that is, the remaining power supply time may be determined to be 150 minutes.

In the case of CASE 3 disclosed in FIG. 3, it shows a reference driving situation in which the camper load uses the power saving current without external charging.

That is, in CASE3, the load of the camper uses the power saving current of 29A. According to an embodiment, in the case of CASE3, the air conditioner in the camper may be used in a power saving mode and current may be consumed with an output of 29A.

In a driving situation such as CASE3, the central processor may form a reference simulation report such as C43 of FIG. 4 .

That is, the central processor can determine the time it takes to be discharged in the case of CASE3. In case of CASE3, the time it takes to be discharged, that is, the remaining power supply time may be determined to be 200 minutes.

In the case of CASE 4 disclosed in FIG. 3, it shows a reference driving situation in which the camper load uses power saving current without external charging. In case of CASE4, the second battery may be charged by driving the vehicle at a constant speed. Also, in CASE4, the camper load uses a power saving current of 29A.

In a driving situation such as CASE4, the central processor may form a reference simulation report such as C44 of FIG. 4 .

That is, the central processor can determine the time it takes to be discharged in the case of CASE4. In case of CASE4, the time it takes to discharge, that is, the remaining power supply time, may consume 1000 minutes.

Meanwhile, referring again to FIG. 4 , FIG. 4 is a graph showing the relationship between the output voltage of the battery and the battery usage time, and the vertical axis indicates the output voltage of the battery and the horizontal axis indicates the usage time of the battery.

Each of the plurality of reference simulation reports may include a remaining power supply time of the second battery based on a relationship between the voltage and current of the second battery.

4 shows that the remaining power supply time for each CASE is determined to be 100 minutes, 150 minutes, 200 minutes, and 1000 minutes.

On the other hand, the central processor interpolates at least two of the plurality of reference simulation reports based on the similarity between the current driving situation of the camper and the reference driving situation of the camper and the use log information to predict the real-time simulation report. can

For example, in the case of CASE2, the camper consumes the maximum power, but in the case of CASE4, the camper consumes the minimum power.

On the other hand, if the current driving situation of the car consumes 50A of current, it does not correspond directly to CASE3 or CASE4, so the central processor can interpolate CASE 3 and CASE4 to predict a new real-time simulation report (C45).

As described above, the user's log information may be used by the central processor to form this new simulation report.

Based on the real-time simulation report C45 derived in this way, the camper may determine the remaining power supply time as 400 minutes.

In addition, based on the real-time simulation report, the power management processor can supply optimized power to each load.

In addition, the central processor may determine the remaining power supply time of the camper in response to the output voltage of the second battery in the real-time simulation report.

Meanwhile, the central processor can apply these behaviors to the newly predicted real-time simulation report.

Referring to FIG. 4 , when the real-time simulation report corresponding to the current driving situation of the vehicle is C45, the central processor may determine the remaining supply time based on the output voltage of the current vehicle's second battery.

That is, if the current driving situation is C45 and the output voltage of the second battery is 11.5V, the remaining supply time may be determined as 100 minutes excluding 300 minutes from 400 minutes.

In this way, the central processor can derive the remaining supply time of the second battery without complicated calculation and deliver the information to the user.

On the other hand, the operation of the present invention described in FIGS. 3 and 4 is only one embodiment of the present invention, and the central processor predicts a real-time simulation report, but based on this, the power management processor supplies power to the load. There are no restrictions.

In addition, the central processor of the camper may also output an interface informing the user of the remaining time based on the current battery (I52).

The corresponding remaining time information may be determined based on the real-time simulation report as described above.

The central processor may transmit the determined user interface as shown in FIG. 5 to an external device such as a smart phone, and the external device may output the interface.

Meanwhile, the user interface described in FIG. 5 is only an embodiment of the present invention, and there is no limitation in the form or function of the user interface.

6 is a diagram illustrating a flowchart according to an embodiment.

Referring to FIG. 6 , the central processor may form a reference simulation report using the reference driving situation ( S100 ).

Also, it is possible to determine the degree of similarity between the current driving situation of the vehicle and the reference driving situation (S200).
