Description

Technical Field

[0001] The present disclosure relates to systems and methods for discharge energy management of a dedicated electric vehicle. Background Art

[0002] As the size of the transportation market for transporting various commodities increases along with the size of the market for electric vehicles, the demand for specialized electric vehicles with refrigeration or freezing functions continues to increase.

[0003] In particular, unlike internal combustion engine vehicles, dedicated electric vehicles with a refrigeration or freezing function can provide an advantage in that the refrigeration or freezing function can be maintained by driving an electric compressor using energy released from a battery even when the vehicle is parked / stopped with the ignition turned off.

[0004] However, conventional dedicated electric vehicles with a cooling or freezing function determine whether the cooling or freezing function can be maintained by only considering the battery state of charge (SOC) indicating the current remaining power of the battery without considering the driving conditions at the destination (e.g., ignition off, parking / stop time, etc.), the driving energy required to the destination, the energy required for cooling or freezing, etc. Therefore, there may be a problem that the existing dedicated electric vehicle may lose the cooling or freezing function when the vehicle stops / stops according to the battery SOC.

[0005] For example, when the battery SOC is lower than a reference value, in addition to achieving the purpose of driving the vehicle to a destination, a conventional special-purpose electric vehicle having a refrigeration or freezing function determines that the battery SOC is insufficient to maintain the refrigeration or freezing function, thereby limiting the battery discharge energy provided to the components performing the refrigeration or freezing function. Therefore, a problem may be caused, so that the conventional special-purpose electric vehicle may not be able to use the refrigeration or freezing function.

[0006] In addition, when a conventional dedicated electric vehicle with a refrigeration or freezing function travels to a destination, it is impossible for the driver to accurately recognize whether the vehicle can easily reach the destination at the current battery SOC level while consuming the battery discharge energy required to maintain the refrigeration function in addition to the battery discharge energy required to drive the vehicle to the destination.

[0007] Therefore, a driver who is worried about the complete discharge of the battery may develop anxiety, and thus, there is a problem in that the driver can only operate the cooling or freezing function conservatively, for example, temporarily turning off the cooling or freezing function.

[0008] The above content is only intended to help understand the background of the embodiments of the present disclosure, and is not intended to mean that the embodiments of the present disclosure fall within the scope of the prior art known to those skilled in the art. Summary of the invention

[0009] The present disclosure relates to a system and method for discharge energy management of a special electric vehicle. Specific embodiments relate to a system and method for discharge energy management of a special electric vehicle, which can appropriately manage the discharge energy from the battery of a special electric vehicle with a refrigeration or freezing function in consideration of the driving destination and driving conditions.

[0010] Therefore, embodiments of the present disclosure have been made keeping in mind the problems arising in the prior art, and embodiments of the present disclosure provide a system and method for discharge energy management for a dedicated electric vehicle, wherein the system and method calculate the driving energy required for the vehicle to travel to a destination and a first required energy for maintaining a refrigeration or freezing function to the destination, and predetermine whether the vehicle can be driven to the destination while consuming the driving energy and the first required energy at the current battery SOC level to notify the driver, thereby stably enabling the vehicle to travel to the destination while maintaining the use of the refrigeration or freezing function.

[0011] In addition, embodiments of the present disclosure provide a system and method for discharge energy management of a dedicated electric vehicle, wherein, when the vehicle stops / stops for a specific period of time when traveling to a destination, the system and method can calculate a second required energy for maintaining a refrigeration or freezing function when the vehicle stops / stops, and determine the available stop / stop time when the second required energy is consumed at the current battery SOC level to notify the driver, thereby stably enabling the vehicle to travel to the destination while maintaining the use of the refrigeration or freezing function.

[0012] According to one embodiment of the present disclosure, a system for discharge energy management of a dedicated electric vehicle can be provided, comprising: a navigation device for inputting a destination and parking / stop time of the vehicle; a controller configured to calculate the driving energy required for the vehicle to travel to the destination and a first required energy for maintaining a refrigeration or freezing function to the destination, and to predetermine whether the vehicle can travel to the destination while consuming the driving energy and the first required energy at a current battery SOC level; and a display device configured to display whether the vehicle can travel to the destination (including a total energy obtained by adding the driving energy and the first required energy) through a command of the controller so that it can be recognized by the driver.

[0013] When it is determined that it is impossible for the vehicle to travel to the destination while consuming the driving energy and the first required energy, the controller may be configured to perform control for displaying a battery discharge energy limit warning on the display device and, in order to simultaneously induce charging of the battery, for displaying a charging station on the navigation device.

[0014] Furthermore, when it is determined that the vehicle can travel to the destination while consuming the driving energy and the first required energy, the controller may be configured to perform control for displaying a message notifying that the vehicle can travel to the destination at the current battery SOC level on the display device.

[0015] Specifically, the controller can be configured to control to: calculate a second required energy required to maintain a refrigeration or freezing function in a parked / stopped state of the vehicle during an input park / stop time input through a navigation device, and determine an available park / stop time in which the vehicle can be parked / stopped while discharging the second required energy based on a current battery SOC level, thereby displaying the available park / stop time on a display device.

[0016] In addition, the controller may be configured to compare the input stop / stop time with the available stop / stop time, and when the input stop / stop time is greater, output a command to the display device to re-input the stop / stop time to a value not greater than the available stop / stop time.

[0017] Furthermore, the controller may be configured to compare the input stop / stop time with the available stop / stop time, and when the available stop / stop time is greater, output a message to the display device indicating that stop / stop is possible during the input stop / stop time.

[0018] Furthermore, when the actual stop / stop time exceeds the above available stop / stop time, the controller may be configured to output a warning message indicating that the battery SOC may drop below a lower limit reference value to the display device.

[0019] The display device may include a display installed inside the vehicle and a smart device owned by the driver.

[0020] According to another embodiment of the present disclosure, a method for discharge energy management of a special-purpose electric vehicle can be provided, comprising: in a controller, confirming that the destination and parking / stop time of the vehicle are input into a navigation device; in the controller, calculating the driving energy required for the vehicle to travel to the destination and a first required energy for maintaining a refrigeration or freezing function to the destination, and determining whether the vehicle can travel to the destination while consuming a total energy obtained by adding the driving energy to the first required energy at a current battery SOC level; and in the controller, controlling to display on a display device whether the vehicle can travel to the destination (including the total energy obtained by adding the driving energy to the first required energy) so that it can be recognized by the driver.

[0021] In addition, when it is determined that the vehicle cannot travel to the destination while consuming the driving energy and the first required energy, a battery discharge energy limit warning can be displayed on the display device, and at the same time, through the control of the controller, a charging station can be further displayed on the navigation device to introduce charging of the battery.

[0022] In addition, when it is determined that the vehicle can travel to the destination while consuming the driving energy and the first required energy, through the control of the controller, a message that the vehicle can travel to the destination at the current battery SOC level can be further displayed on the display device.

[0023] Specifically, when a stop / stop time is input through a navigation device in a state where the vehicle is parked / stopped, the method may further include, in a controller, calculating a second required energy required to maintain a refrigeration or freezing function during the input stop / stop time input through the navigation device, in the controller, determining an available stop / stop time in which parking / stopping can be performed while discharging the second required energy based on a current battery SOC level, and in the controller, controlling the determined available stop / stop time to be displayed on a display device.

[0024] Furthermore, in the controller, the input stop / stop time may be compared with the available stop / stop time, and when the input stop / stop time is greater, a command to re-input the stop / stop time to a value not greater than the available stop / stop time may be output to the display device.

[0025] Furthermore, in the controller, the input stop / stop time may be compared with the available stop / stop time, and when the available stop / stop time is greater, a message indicating that the input stop / stop time is appropriate may be output to the display device.

[0026] Furthermore, when the actual stop / stop time exceeds the available stop / stop time, in the controller, a warning message indicating that the battery SOC may drop below a lower limit reference value may be output to the display device.

[0027] As described above, through the above-mentioned features, the embodiments of the present disclosure provide the following effects.

[0028] First, when a destination of a special-purpose electric vehicle with a refrigeration or freezing function is input, an embodiment of the present disclosure can calculate the driving energy required for the vehicle to travel to the destination and the first required energy for maintaining the refrigeration or freezing function to the destination, and determine whether the vehicle can travel to the destination while consuming the driving energy and the first required energy at the current battery SOC level, so as to notify the driver in advance, thereby stably enabling the vehicle to travel to the destination while maintaining the use of the refrigeration or freezing function.

[0029] Secondly, the driver can accurately recognize whether the vehicle can easily reach the destination with the current battery SOC level while consuming the battery discharge energy required to maintain the refrigeration function in addition to the battery discharge energy required to drive the vehicle to the destination, thereby preventing the driver from worrying about complete discharge of the battery and enabling the driver to drive stably.

[0030] Third, when the vehicle stops / stops for a specific period of time when driving to a destination, an embodiment of the present disclosure can calculate a second required energy for maintaining a refrigeration or freezing function when the vehicle stops / stops, and determine the actual available stop / stop time when the second required energy is consumed at the current battery SOC level to notify the driver in advance, so as to allow the driver to accurately identify the actual available stop / stop time, thereby preventing the driver from worrying about a complete discharge of the battery due to the stop / stop time, and stably driving the vehicle to the destination while maintaining the use of the refrigeration or freezing function.

[0038] Hereinafter, exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0039] Figure 1 is a control configuration diagram showing a system for discharge energy management of a dedicated electric vehicle according to an embodiment of the present disclosure, and Figure 2 and Figure 3 1 and 2 are flowcharts each illustrating a method for discharge energy management of a special electric vehicle according to an embodiment of the present disclosure.

[0040] Embodiments of the present disclosure focus on calculating the driving energy required for a vehicle to travel to a destination, a first required energy for maintaining a refrigeration or freezing function to the destination, and a second required energy for maintaining a refrigeration or freezing function when the vehicle is parked / stopped, and determining whether the vehicle can travel to the destination at the current battery SOC level while consuming the driving energy, the first required energy, and the second required energy, thereby stably enabling the vehicle to travel to the destination while maintaining the use of the refrigeration or freezing function.

[0041] For this reason, Figure 1As shown, a system for discharge energy management of a dedicated electric vehicle according to an embodiment of the present disclosure includes: a navigation device 10 for inputting a destination and a parking / stop time of the vehicle; a controller 20, configured to calculate the driving energy required for the vehicle to travel to the input destination and a first required energy for maintaining a refrigeration or freezing function to the input destination, and to predetermine whether the vehicle can travel to the destination while consuming the driving energy and the first required energy at the current battery SOC level; and a display device 30, configured to display whether the vehicle is likely to travel to the destination (including the total energy obtained by adding the driving energy to the first required energy through a command of the controller 20) for identification by the driver.

[0042] The controller 20 is an upper controller, and is configured to receive current battery SOC information from the battery controller 40 which is a lower controller.

[0043] The display device 30 may include a display 31 for an instrument panel installed in a vehicle and a smart device 32 (such as a smart phone, etc.) owned by a driver.

[0044] On the other hand, the driving energy required for the vehicle to travel to the destination is the discharged energy of the battery discharged to the driving motor of the electric vehicle, and can be determined as a value obtained by subtracting the margin energy consumed by using air conditioning, etc. from the available energy of the battery used when calculating the remaining fuel drivable distance (DTE) reflecting the destination.

[0045] Furthermore, the first required energy may be energy consumed by a compressor driven to maintain a refrigeration or freezing function to a destination.

[0046] After calculating the driving energy required for the vehicle to travel to the destination and the first required energy for maintaining the refrigeration or freezing function to the input destination as input through the navigation device 10, when it is determined that the vehicle cannot travel to the destination while consuming the calculated driving energy required for the vehicle to travel to the destination and the first required energy for maintaining the refrigeration or freezing function to the input destination, the controller 20 is configured to execute control for displaying a battery discharge energy limit warning on the display 31 and the smart device 32 (each of which is a display device 30) and at the same time for displaying a charging station on the navigation device to introduce charging of the battery.

[0047] Therefore, the driver can realize that with the current battery SOC level, the vehicle can travel to the destination, however, it is not possible to maintain the refrigeration or freezing function of the items in the loading box. Therefore, when driving the vehicle to the destination, the electric vehicle charging station can guide the driver to stop to recharge the battery.

[0048] When it is determined that the vehicle can travel to the destination while consuming driving energy and the first required energy, the controller 20 is configured to execute control for displaying a message on the display 31 and the smart device 32 (each being a display device 30) notifying that the vehicle can travel to the destination at the current battery SOC level.

[0049] Therefore, the driver can accurately recognize whether the vehicle can easily reach the destination at the current battery SOC level while consuming the battery discharge energy required to maintain the cooling function in addition to the battery discharge energy required to drive the vehicle to the destination. Therefore, the anxiety of the driver who is worried about the complete discharge of the battery can be prevented, so that stable driving can be achieved.

[0050] When the vehicle stops / stops for a specific period of time when driving to the destination, the embodiment of the present disclosure can calculate the second required energy to maintain the refrigeration or freezing function when the vehicle stops / stops, and determine the duration that the vehicle can stop / stop while consuming the second required energy at the current battery SOC level to notify the driver. Therefore, another aspect of the embodiment of the present disclosure is to enable the driver to stably drive the vehicle to the destination while maintaining the use of the refrigeration or freezing function.

[0051] To this end, the controller 20 is configured to perform the following control: calculate the second required energy required to maintain the refrigeration or freezing function in the parked / stopped state of the vehicle during the input park / stop time input through the navigation device 10, and determine the available park / stop time in which the vehicle can be parked / stopped while releasing the second required energy based on the current battery SOC level, thereby displaying the available park / stop time on the display 31 and the smart device 32 (each of which is a display device 30).

[0052] At this time, in the ignition-off state, when the utility mode is used (the utility mode refers to a mode of using battery power in external devices for camping), when the vehicle is in phase P, the controller 20 recognizes that the vehicle is in a parked / stopped state.

[0053] In addition, the controller 20 is configured to perform the following control: compare the input stop / stop time input through the navigation device 10 with the available stop / stop time in which the vehicle can stop / stop while discharging the second required energy based on the current battery SOC level, and when the input stop / stop time is greater, display a command to re-enter the stop / stop time to a value not greater than the available stop / stop time on the display 31 and the smart device 32 (each of which is a display device 30).

[0054] On the other hand, the controller 20 is configured to perform the following control: compare the input stop / stop time input through the navigation device 10 with the available stop / stop time in which the vehicle can stop / stop while discharging the second required energy based on the current battery SOC level, and when the available stop / stop time is greater, display a message on the display 31 and the smart device 32 (each of which is a display device 30) indicating that stopping / stopping is possible during the input stop / stop time.

[0055] Therefore, when the driver wants to park / stop the vehicle for a certain period of time at a service area or the like when driving to a destination, the driver can clearly recognize the actual parking / stop time that can maintain the refrigeration or freezing function of the internal items of the loading box, and thus, the driver's anxiety of worrying about complete discharge of the battery due to the parking / stop time can be prevented.

[0056] On the other hand, when the actual parking / stop time exceeds the above-mentioned available parking / stop time, the controller 20 is configured to perform the following control: a warning message indicating that the battery SOC may drop below the lower limit reference value as the second required energy for maintaining the refrigeration or freezing function continues to be consumed is displayed on the display 31 and the smart device 32 (each of which is a display device 30), thereby allowing the driver to recognize that the vehicle needs to be started immediately without further parking / stopping.

[0057] Here, the method for discharging energy management for a dedicated electric vehicle according to an embodiment of the present disclosure based on the above control configuration is referred to in sequence. Figure 2 and Figure 3 Description is as follows.

[0058] First, in S101 , the driver inputs a destination via the navigation device 10 in the ignition on or ignition off state.

[0059] Therefore, in S102 , after confirming that the destination is input through the navigation device 10 , the controller 20 calculates the driving energy required for the vehicle to travel to the destination of the vehicle.

[0060] The driving energy is the discharged energy of the battery discharged to the driving motor of the electric vehicle, and can be determined as a value obtained by subtracting the remaining energy consumed by using the air conditioner, etc. from the available energy of the battery used when calculating the remaining fuel drivable distance (DTE) reflecting the destination.

[0061] Subsequently, in S103 , the controller 20 calculates a first required energy for maintaining a refrigeration or freezing function to a destination.

[0062] The first required energy may be energy consumed by a compressor driven to maintain a refrigeration or freezing function to a destination.

[0063] At this time, in S104 , the total energy obtained by adding the driving energy to the first required energy may be displayed on the display device 30 through the control of the controller 20 .

[0064] Next, in S105 , the controller 20 determines whether the vehicle can travel to the destination at the current battery SOC level while consuming the total energy obtained by adding the driving energy to the first required energy.

[0065] More specifically, the controller 20 is configured to perform the following control: displaying the total energy obtained by adding the driving energy to the first required energy on the display 31 and the smart device 32 (each of which is a display device 30), and at the same time, displaying the determination result of whether the vehicle can travel to the destination while consuming the total energy obtained by adding the driving energy to the first required energy at the current battery SOC level on the display 31 and the smart device 32 so that it can be recognized by the driver.

[0066] When it is determined in the above step S105 that it is impossible for the vehicle to travel to the destination while consuming the total energy obtained by adding the calculated driving energy to the first required energy, then in S106, through the control of the controller 20, a battery discharge energy limit warning is displayed on the display 31 and the smart device 32 (each of which is a display device 30), and at the same time, a step of displaying the charging station on the screen of the navigation device 10 is executed to guide the charging of the battery.

[0067] Therefore, the driver can realize that it is possible to drive to the destination with the current battery SOC level, but it is not possible to maintain the refrigeration or freezing function of the items in the loading box. Therefore, when driving the vehicle to the destination, the electric vehicle charging station can make the driver stop to recharge the battery.

[0068] On the other hand, when it is determined in the above step S105 that the vehicle can travel to the destination while consuming the driving energy and the first required energy, in S107, through the control of the controller 20, a step is performed to display a message on the display 31 and the smart device 32 (each of which is a display device 30) notifying that the vehicle can travel to the destination at the current battery SOC level.

[0069] Therefore, the driver can accurately recognize whether the vehicle can easily reach the destination at the current battery SOC level while consuming the battery discharge energy required to maintain the cooling function in addition to the battery discharge energy required to drive the vehicle to the destination through the message information displayed on the display 31 and the smart device 32. Therefore, the anxiety of the driver who is worried about the complete discharge of the battery can be prevented, and stable driving can be performed.

[0070] On the other hand, when it is determined in S105 that the vehicle can travel to the destination while consuming driving energy and the first required energy, in S107, under the control of the controller, a step is executed to display a message on the display device notifying that the vehicle can travel to the destination with the current battery SOC level.

[0071] Therefore, the driver can accurately recognize whether the vehicle can easily reach the destination at the current battery SOC level while consuming the battery discharge energy required to maintain the cooling function in addition to the battery discharge energy required to drive the vehicle to the destination through the message information displayed on the display 31 and the smart device 32. Therefore, the anxiety of the driver who is worried about the complete discharge of the battery can be prevented, and stable driving can be performed.

[0072] Meanwhile, when the vehicle stops / stops for a specific period of time when traveling to the destination, the driver inputs the stop / stop time through the navigation device 10 in a state where the vehicle is stopped / stopped in S108 .

[0073] At this time, in the ignition off state, when using the utility mode (the utility mode refers to a mode of using battery power in an external device for camping), when the vehicle is in stage P, the controller 20 identifies the vehicle as being in a parked / stopped state and can receive a parked / stopped time input from the navigation device 10.

[0074] Next, in S109 , the controller 20 calculates a second required energy required to maintain the cooling or freezing function during the input stop / stop time input through the navigation device 10 in the stopped / parked state.

[0075] The second required energy may be energy consumed by a compressor or the like driven to maintain a refrigeration or freezing function during the stop / stop time.

[0076] Subsequently, in step S110, the controller 20 is configured to perform control to determine an available stop / stop time during which the vehicle can stop / stop when discharging the second required energy based on the current battery SOC level, thereby displaying the available stop / stop time on the display 31 and the smart device 32 (each of which is a display device 30).

[0077] Therefore, the driver can recognize the available parking / stopping time for maintaining the refrigeration or freezing function through the display 31 and the screen of the smart device 32 .

[0078] Subsequently, in S111, the controller 20 is configured to perform the following control: when the input stop / stop time is greater, in S112, a command to re-enter the stop / stop time to a value not greater than the available stop / stop time is displayed on the display 31 and the smart device 32 (each of which is a display device 30).

[0079] Therefore, the driver can re-input the desired stop / stop time within the available stop / stop time for maintaining the cooling or freezing function.

[0080] On the other hand, the controller 20 is configured to perform the following control, compare the input parking / stop time with the available parking / stop time, and when the available parking / stop time is greater, in S113, display a message indicating that parking / stopping is possible during the input parking / stop time on the display 31 and the smart device 32 (each of which is a display device 30).

[0081] Therefore, the driver can view the message displayed on the display device 30 and recognize that the cooling or freezing function can be maintained during the parking / stopping time input thereby.

[0082] Meanwhile, when the vehicle stops / parks, the controller 20 is configured to perform the following control: in S114, the actual stop / stop time is compared with the available stop / stop time, and when the actual stop / stop time exceeds the available stop / stop time, in S115, a warning message indicating that the battery SOC may drop below a lower limit reference value is displayed on the display 31 and the smart device 32 (each of which is a display device 30).

[0083] Therefore, the driver can recognize through the warning message that the actual stop / stop time exceeds the available stop / stop time, thereby guiding the vehicle to start moving toward the destination.

[0084] Therefore, when the vehicle stops / stops for a specific period of time when driving to a destination, an embodiment of the present disclosure can calculate a second required energy for maintaining a refrigeration or freezing function when the vehicle stops / stops, and determine the actually available stop / stop time while consuming the second required energy at the current battery SOC level to notify the driver in advance, so as to allow the driver to accurately identify the actually available stop / stop time, thereby preventing the driver from worrying about a complete discharge of the battery due to the stop / stop time, and stably enabling the vehicle to travel to the destination while maintaining the use of the refrigeration or freezing function.

[0085] Although the embodiments of the present disclosure have been described in detail above using various embodiments, the scope of the embodiments of the present disclosure is not limited to the above-mentioned embodiments, and it should be understood that various modifications and improvements by those skilled in the art using the basic concept of the embodiments of the present disclosure defined in the appended claims will also be included within the right scope of the embodiments of the present disclosure.
