The following description is, therefore, not to be taken in a limiting sense.
[0032] Fig. 1 shows a schematic perspective view according to an embodiment of a motor vehicle 10 including at least one assistance system 12. The motor vehicle 10 is at least partially electrically operated. The motor vehicle 10 may also be fully electrically operated. The motor vehicle 10 includes at least one battery 14. The battery 14 may also be referred to as an electric power storage device.
[0033] The assistance system 12 may include at least one capturing device 16 and one electronic computing device 18.
[0034] In particular, Fig. 1 shows a method for determining an adaptive charging profile P for the motor vehicle 10. The capturing device 16 may collect a current status information 20, 22. For example, the capturing device 16 may capture a battery's health information, a time-of-the-day, an ambient data input, a cloud data input, or a current location of the motor vehicle, a driver profile 24 of a driver of the motor vehicle 10 may be provided by the electronic computing device 18. Furthermore, a historical data information 26 may be provided by the electronic computing device 18. The adaptive charging profile P may be determined based on the current status information 20, 22, the driver profile 24, and the historical information 26 by the electronic computing device 18.
[0035] In particular, the electronic computing device 18 may include an artificial intelligence 28 for determining the adaptive charging profile P. [0036] Furthermore, the current status information 20, 22 may include the battery's health information, the time-of-the-day, the ambient information, and/or the current location of the motor vehicle.
[0037] In another embodiment the historical information 26 may be a charging profile of the motor vehicle 10 developed in the past. For example, the empirical data may include data from a previous hour(s), day(s), month(s), and/or year(s). Furthermore, the adaptive charging profile P may include a profile for fast charging 30 and for optimal charging 32. Furthermore, information from the grid 32 such as a charging capacity of a charging station for charging the motor vehicle 10 may be taken into consideration. In other embodiments, information from the grid 32 or grid information may include power load conditions, battery storage conditions, current flow conditions, and/or other relevant information.
[0038] In particular, a more efficient control of the charging time using information from the electronic computing device 18 may include historical information, location data, the driver's profile 24, the battery's health status, the time of the day, the cloud data, and the ambient data.
[0039] As represented in the Fig. 1, the driving range of the motor vehicle 10 may be predicted in a main loop by a vehicle onboard prediction algorithm triggering notifications back to a driver via an existent display device and/or audio prompts if enabled. The onboard prediction algorithm collects historical and/or driver profile information from the electronic computing device 18 such as the state of charge, battery health, battery temperature, intended driving distance, or other characteristics.
[0040] The automotive assistance system 12 may recommend the driver an optimal location to recharge the motor vehicle 10 based on context. In some embodiments, the automotive assistance system 12 may collect information regarding the urgency, time of the day, ambient conditions, state of the driver, history of the charging, history of the discharging, and/or profile of the driver and select an adaptive charging profile P appropriate with a location and urgency of charging.
[0041] For example, the driver may plug in a charging connector or connect to a wireless charging system if the motor vehicle 10 is equipped with wireless charging. The driver may select a charging profile on the user interface present in the car's infotainment system, and the charging activity may commence. In a different embodiment, the driver's selection may be included in the determination of the adaptive charging profile P and adaptive discharging profile D as shown in Fig. 2.
[0042] Fig. 2 shows another schematic perspective view according to another embodiment of a motor vehicle 10 including at least one assistance system 12 and one battery 14. The assistance system 12 may include at least one capturing device 16 and one electronic computing device 18.
[0043] Fig. 2 illustrates another embodiment of a method for determining an adaptive charging profile P and an adaptive discharging profile D for the motor vehicle 10. The capturing device 16 may collect a current status information 20, 22. For example, the capturing device 16 may capture a battery's health information, a time-of-the-day, an ambient data input, a cloud data input, or a current location of the motor vehicle, a driver profile 24 of a driver of the motor vehicle 10 may be provided by the electronic computing device 18. Furthermore, a historical data information 26 may be provided by the electronic computing device 18. The adaptive charging profile P and the adaptive discharging profile D may be determined based on the current status information 20, 22, the driver profile 24, the historical information 26 by the electronic computing device 18, and/or related information. For example, the determination of the adaptive charging profile P and the adaptive discharging profile D may be based on the amount of power required to charge the motor vehicle 10, the timing of the charging or discharging process, or the cost of the charging service.
[0044] In particular, the electronic computing device 18 may include an artificial intelligence 28 for determining the adaptive charging profile P and adaptive discharging profile D. [0045] Furthermore, the current status information 20, 22 may include the battery's health information, the time-of-the-day, the ambient information, and/or the current location of the motor vehicle 10. In some embodiments, the ambient information may include a charging current flow 38 and/or a discharging flow 40.
[0046] In another embodiment the historical information 26 may be a charging profile of the motor vehicle 10 developed in the past. For example, the empirical data may include data from a previous hour(s), day(s), month(s), and/or year(s). Furthermore, the adaptive charging profile P or the adaptive discharging profile may include a profile for fast charging 30 and/or for optimal charging 32. Furthermore, information from the grid 32 such as a charging capacity of a charging station for charging the motor vehicle 10 may be taken into consideration.
[0047] In particular, a more efficient control of the charging time using information from the electronic computing device 18 may include historical information, location data, the driver's profile 24, the battery's health status, the time of the day, the cloud data, and the ambient data.
[0048] As represented in the Figs. 1 and 2, the driving range of the motor vehicle 10 may be predicted in a main loop by a vehicle onboard prediction algorithm triggering notifications back to a driver via an existent display device and/or audio prompts if enabled. The onboard prediction algorithm collects historical and/or driver profile information from the electronic computing device 18 such as the state of charge, battery health, battery temperature, intended driving distance, or other characteristics.
[0049] The automotive assistance system 12 may recommend the driver an optimal location to recharge the motor vehicle 10 based on context. In some embodiments, the automotive assistance system 12 may collect information regarding the urgency, time of the day, ambient conditions, state of the driver, history of the charging, history of the discharging, and/or profile of the driver and select an adaptive charging profile P appropriate with a location and urgency of charging.
[0050] For Figs. 1 or 2, there may be at least two charging options based on the location of the charging activity. A first option may be an at home charging option. If there is an urgent status detected by the motor vehicle 10, the charging power may be set to a maximum value available from the grid. If there is no urgent status detected, the charging power may be set at a normal rate predefined based on a default profile. A second option may be a remote charging profile, the charging power may be set at the maximum input power available from the chosen charging station. In certain embodiments, the amount of power drawn from the charging station may be determined based on the adaptive charging profile P, for example, selected based on urgency of charging and discharging and battery parameters. For example, the battery parameters may include the state of charge, state of health, charging power, and/or other values for increasing the battery life. A state-of-the-art charging profile may be implemented to determine the adaptive charging profile P and discharging profile D. [0051] For the charging options, if a vehicle-to-grid (V2G) communication is available and enabled by the driver, the motor vehicle 10 may provide energy back to the grid following the adaptive discharging profile D when discharging operation dependencies are within acceptable operation thresholds. For example, the discharging operation dependencies may include the state of health and state of charge of the battery. During the discharging operation, the charge level, the discharging profile D, and remaining discharge time left may be checked periodically to enable a re-charging, if desired, for the remaining time the vehicle is stationed at the charging location.
[0052] Fig. 3 shows a flow chart according to an embodiment of the method. In a first step S3.1, the method may start. In a second step S3.2, a range prediction query of the assistance system 12 may be determined. In a third step S3.3, the range prediction is checked to determine if the range prediction is low. If the range prediction is low, a fourth step S3.4 is performed, in which the driver is notified of a charging location and an adaptive charging profile P list may be generated. For this purpose, inputs 34 are collected for the determination of the charging location and the adaptive charging profile P. In some embodiments, inputs 34 may include an urgency status, historical information, and/or a price. If the range prediction is not low after the third step S3.3, the method may return to the second step S3.2.
[0053] Fig. 4 shows another flow chart according to an embodiment of the method. In a first step S4.1, the method may start. In a second step S4.2, a wireless charging option may be checked. If the wireless charging option is initiated, a third step S4.3 may be performed, in which the vehicle location is checked. If no wireless charging is initiated, the wired charging option may be checked. If a charging connector is plugged in at the fourth step S4.4, the third step S4.3 may be performed, in which the vehicle location is checked.
[0054] If the motor vehicle 10 is at home, an urgent status may be checked at a fifth step S4.5. If there is an urgent status, a sixth step S4.6 may be performed, in which the maximal power allowed for charging may be provided. Coming from the third step S4.3, if the motor vehicle 10 is not at home, an eighth step S4.8 may be performed, in which the availability of a vehicle-to-grid network is checked. If the motor vehicle 10 does not have access to an available vehicle-to-grid network, the maximal power allowed for charging may be provided at a ninth step S4.9. If the motor vehicle 10 does have access to the available vehicle-to-grid network at the eighth step S4.8, the connection to the vehicle-togrid network at a seventh step S4.7 may be checked. Additionally, if the status is not urgent at the first step S4.5, the seventh step S4.7 may be performed. For example, the method may include the electronic computing device 18 may determine whether the feature to enable the motor vehicle 10 to connect to the vehicle-to-grid connection is enabled or disabled.
[0055] Coming from the seventh step S4.7, if the connection to the vehicle-to-grid network is disabled, the optimal profile for charging may be kept, which is shown in a tenth step S4.10. If the connection to the vehicle-to-grid network is enabled, an eleventh step S4.11 may be performed, in which the battery health may be checked. For example, the battery 14 may include an optimal state of health, and the optimal state of health of the battery 14 may be determined. If the state of health of the battery 14 is optimal, a twelfth step S4.12 may be performed, in which the state of charge of the battery 14 may be checked. If the state of charge of the battery 14 is optimal, a thirteenth step S4.13 may be performed, in which a discharging profile from the adaptive discharging profile list may be updated. After the thirteenth steps S4.13, a fourteenth step S4.14 may be performed, in which the remaining time the vehicle is stationed at the charging location may be checked, which is further described in Fig. 5.
[0056] Coming from the eleventh step S4.11 or from the twelfth step S4.12, if the state of the battery's health is not optimal and/or the state of charge of the battery 14 is not optimal, a fifteenth step S4.15 may be performed, in which the driver may be notified and warned based on the collected data such as the state of the battery's health and state of charge of the battery 14. After the fifteenth step S4.15, a sixteenth step S4.16 may be performed, in which the charging profile is updated from the adaptive charging profile P list. Subsequently, a seventeenth step S4.17 may be performed, in which the motor vehicle 10 and/or the battery 14 is charged based on the determined adaptive charging profile P. Fig. 5 shows another flow chart according to an embodiment of the method. In a first step 55.1, the method may start. In a second step 55.2, the remaining time the vehicle is stationed at the charging location may be checked. If there is enough time left, a third step 55.3 may be performed, in which a discharge limit of the battery 14 may be checked. If the discharge limit of the battery 14 is not met, a fourth step S5.4 may be performed, in which the battery 14 may be discharged. If the discharge limit of the battery 14 is met at the third step S5.3 or if there is not enough time left at the charging location at the second step S5.2, a fifth step S5.5 may be performed, in which the charging profile may be updated from the adaptive charging profile P list. After the update of the charging profile at the fifth step S5.5, a sixth step S5.6 may be performed, in which the motor vehicle 10 may be charged. In some embodiments, the motor vehicle 10 may be re-charged, if desired, for the remaining time the vehicle is stationed at the charging location based on periodic checks of the charge level and remaining discharge time.
