Description

Technical Field

[0001] The present invention relates to the field of vehicle networking, and more particularly, to a method and system for displaying carbon dioxide equivalent for a vehicle. Background Art

[0002] To achieve climate goals, environmentally conscious behavior is required in all areas of life, including personal mobility. An important factor in this is that energy not only comes from sustainable resources but is also used efficiently.

[0003] For electric vehicles, the total amount of carbon dioxide equivalents generated per kilometer depends on the energy mix during charging (carbon dioxide equivalent per kilowatt-hour) and the output power (watts) at that time. The carbon dioxide equivalent per kilowatt-hour indicates how many grams of carbon dioxide are released into the atmosphere for every 1kWh of electricity consumed, which also represents the carbon emissions from the use of electric vehicles.

[0004] Some electric vehicles currently on the market already have the ability to display or calculate the current charge level (for example, showing power consumption per kilometer / per 100 kilometers). However, there is currently no known solution that links the carbon equivalent (CO2eq) of charging to the current power and displays it to the driver on the instrument panel. This means that drivers cannot view the amount of greenhouse gases generated by their current driving style while driving, resulting in drivers not consciously adopting more environmentally friendly driving methods when carbon emissions are higher or seeking charging times or charging stations with lower carbon equivalents.

[0005] Therefore, in order to further save energy and reduce emissions and make positive contributions to carbon emission reduction in the electric vehicle field, it is desired to provide a carbon dioxide equivalent display solution for vehicles. Summary of the Invention

[0032] The present invention will be described in detail below with reference to the accompanying drawings. The features of the present invention will be further apparent from the following detailed description. The term "vehicle" used throughout this specification refers to any type of automobile, including but not limited to cars, vans, trucks, buses, etc. For simplicity, the present invention will be described with respect to an "automobile." The term "A or B" used in this specification means "A and B" and "A or B," and does not imply that A and B are exclusive, unless otherwise specified.

[0033] At present, in order to achieve "green and low-carbon" for electric vehicles, there are already some methods (such as adopting economic modes, etc.) to achieve energy conservation and emission reduction on the vehicle side. However, considering the carbon emissions during charging, there is currently no visual solution to feedback to users on the vehicle side the carbon equivalent generated per kilowatt-hour during the current driving process (which actually also depends on the composition of the energy combination during charging).

[0034] In order to solve the above problems and realize visual feedback of carbon equivalents on the vehicle side, this application proposes a carbon dioxide equivalent display solution for vehicles, which motivates the driver to adopt a more environmentally friendly driving method, charge when the proportion of sustainably generated energy in the energy combination is high, etc. by displaying the current carbon equivalent per kilometer or per 100 kilometers to the driver on the vehicle side, thereby promoting carbon emission reduction on the vehicle side.

[0035] like Figure 1 As shown, Figure 1 FIG2 is a schematic diagram of a carbon dioxide equivalent display system 100 for a vehicle according to an embodiment of the present invention. The system 100 may include at least a data acquisition module 102 , a carbon equivalent determination module 104 , and a carbon equivalent display module 106 .

[0036] The data acquisition module 102 can obtain the carbon intensity gCO2eq / kWh corresponding to the corresponding 1kWh charging amount during charging for every 1 kilowatt-hour (kWh) consumed by the vehicle during driving, where the carbon intensity indicates the carbon dioxide equivalent per kWh (how many grams of carbon dioxide are released into the atmosphere for every 1kWh of electricity consumed).

[0037] In one embodiment, the carbon intensity may be obtained from a time series of carbon intensity corresponding to each kWh of charging during charging in a first-in-first-out manner.

[0038] In further embodiments, the time series of carbon intensity may be stored in the vehicle's memory or IT backend.

[0039] In one embodiment, the carbon intensity corresponding to each kWh of charging may depend on the composition of the energy mix during charging and may be obtained from the API of the corresponding electricity supplier during charging (e.g., from the cloud). Figure 2 A schematic architecture diagram related to obtaining carbon intensity is further described in .

[0040] like Figure 2 As shown, when the vehicle is charging, the corresponding charging station 202 can, for example, request the time series of carbon intensity corresponding to the charging amount per kWh during charging (which actually depends on the composition of the energy combination during charging) from the API of the corresponding electricity supplier or some portal website that displays the daily composition of the current energy combination, and obtain the corresponding time series of carbon intensity from it.

[0041] This is Figure 3 Described in further detail in Figure 3A schematic bar graph showing the change in carbon intensity over time T obtained from an API according to one embodiment of the present invention is shown. For example, when the vehicle is charging, in response to a request for a time series of carbon intensity corresponding to each kWh of charging amount (gCO2eq / kWh), the carbon intensity at each corresponding time point can be recorded and transmitted to the charging vehicle via the charging station.

[0042] return Figure 2 , then, the charging station may transmit the corresponding time series of carbon intensity to the vehicle's memory or IT backend 204 for storage.

[0043] When the vehicle is driving, the time series of carbon intensity can be retrieved from the vehicle's memory or the IT backend connected to the vehicle according to the first-in-first-out principle. In this way, the carbon equivalent during charging can be linked to the current power during driving for subsequent calculation and display of the carbon equivalent per kilometer.

[0044] return Figure 1 Furthermore, the data acquisition module 102 may determine the vehicle's current power consumption per kilometer (kWh / km) or per 100 kilometers (kWh / 100km). Power consumption per kilometer / per 100 kilometers may be an important parameter for measuring the endurance of an electric vehicle.

[0045] The carbon equivalent determination module 104 may then determine the current carbon dioxide equivalent gCO 2 eq / km of the vehicle based on the carbon intensity gCO 2 eq / kWh and the electricity consumption kWh / km.

[0046] In one embodiment, the current carbon dioxide equivalent per kilometer (gCO2eq / km) of the vehicle may be calculated by multiplying the carbon intensity (gCO2eq / kWh) and the electricity consumption per kilometer (kWh / km).

[0047] The carbon equivalent display module 106 can display the current carbon dioxide equivalent gCO2eq / km (or gCO2eq / 100km) of the vehicle to the driver.

[0048] In one embodiment, the carbon equivalent display module may be provided as a dashboard, a head-up display (HUD), or any other suitable display within the vehicle.

[0049] Furthermore, when the calculated current gCO2eq / km of the vehicle is higher than a threshold, appropriate carbon emission reduction measures can be recommended to the driver (including, for example, activating the economy mode, changing to a more environmentally friendly driving style (for example, maintaining a medium to low speed, using the vehicle's kinetic energy recovery function, reducing driving on roads with poor road conditions, using internal circulation to save power, controlling load, etc.) or any other appropriate carbon emission reduction methods).

[0050] Furthermore, time periods with lower carbon intensity (eg, a higher proportion of sustainably generated energy in the energy mix) and corresponding charging stations may be recommended to the user for selection during the next charging.

[0051] Those skilled in the art will appreciate that the carbon dioxide equivalent display system of the present invention may be implemented in the form of hardware or software, and the modules may be merged or combined in any appropriate manner.

[0052] Figure 4 An example scenario of carbon dioxide equivalent display on a vehicle side according to an embodiment of the present invention is shown.

[0053] like Figure 4 As shown, the vehicle's central control screen displays the current electricity consumption (kWh / km) and the current CO2 equivalent (gCO2eq / km). This can encourage drivers to adopt more environmentally friendly driving methods or choose charging times or charging stations with lower carbon equivalents.

[0054] Of course, it is understood that the above scenario is merely an example, and the current gCO2eq / km may be displayed in any other manner on any suitable display screen in the vehicle (of course, the electricity consumption per 100 kilometers (kWh / 100km) may also be obtained and gCO2eq / 100km may be displayed).

[0055] Figure 5 FIG. 4 is a schematic flow chart of a method 500 for displaying carbon dioxide equivalent for a vehicle according to an embodiment of the present invention.

[0056] The method 500 starts at step 502 . The data acquisition module 102 may acquire the carbon intensity (gCO 2 eq / kWh) corresponding to the corresponding 1 kWh of charging during vehicle driving, for every 1 kWh consumed. The carbon intensity indicates carbon dioxide equivalent per kWh.

[0057] In one embodiment, the carbon intensity may be obtained from a time series of carbon intensity corresponding to each kWh of charging during charging in a first-in-first-out manner.

[0058] In a further embodiment, the above-mentioned time series of carbon intensity is stored in the vehicle's memory or IT backend, and the corresponding carbon intensity can be retrieved from the vehicle's memory or IT backend on a first-in-first-out basis when the vehicle is driving.

[0059] In one embodiment, the carbon intensity corresponding to each kWh of charging may depend on the composition of the energy mix during charging and may be obtained from an application programming interface (API) of a corresponding electricity supplier during charging.

[0060] In step 504 , the data acquisition module 102 may determine or acquire the current power consumption per kilometer (kWh / km) of the vehicle (of course, the power consumption per 100 kilometers (kWh / 100km) may also be acquired).

[0061] In step 506 , the carbon equivalent determination module 104 may determine the current carbon dioxide equivalent gCO 2 eq / km of the vehicle according to the carbon intensity gCO 2 eq / kWh and the electricity consumption kWh / km.

[0062] In one embodiment, the current carbon dioxide equivalent per kilometer (gCO2eq / km) of the vehicle may be calculated by multiplying the carbon intensity (gCO2eq / kWh) and the electricity consumption per kilometer (kWh / km).

[0063] In step 508 , the carbon equivalent display module 106 may display the calculated carbon dioxide equivalent per kilometer gCO 2 eq / km to the driver.

[0064] In one embodiment, the carbon equivalent display module 106 may display the vehicle's current carbon dioxide equivalent gCO 2 eq / km to the driver on a dashboard, a head-up display, or any other display within the vehicle.

[0065] Further preferably, when the vehicle's current carbon dioxide equivalent per kilometer gCO2eq / km is higher than a predetermined threshold, appropriate carbon emission reduction measures can be recommended to the driver, where the carbon emission reduction measures may, for example, include activating an economic mode, changing to a more environmentally friendly driving style, or any other appropriate carbon emission reduction method.

[0066] Further preferably, time periods with lower carbon intensity (ie, better energy combinations) and corresponding charging stations can be recommended to the user for selection during the next charging.

[0067] Therefore, by taking into account the energy mix during charging (carbon equivalent per kilowatt-hour gCO2eq / kWh) and the power consumption during driving (kWh / km), the current carbon equivalent (greenhouse gas emissions) per kilometer or per 100 kilometers can be fed back to the driver in a visual manner. This can, for example, encourage the driver to adopt a more environmentally friendly driving style, thereby promoting carbon emission reduction on the vehicle side.

[0068] Figure 6 An exemplary vehicle 600 supporting CO2 equivalent display according to one embodiment of the present invention is shown. Vehicle 600 may include various software and hardware components connected via bus 614.

[0069] The vehicle 600 may include the carbon dioxide equivalent display system 100 as described above, which may be configured to obtain a carbon intensity gCO2eq / kWh corresponding to a corresponding 1kWh charging amount during charging for every 1kWh consumed when the vehicle is traveling, wherein the carbon intensity indicates carbon dioxide equivalent per kWh; determine the vehicle's current electricity consumption per kilometer kWh / km; determine the vehicle's current carbon dioxide equivalent per kilometer gCO2eq / km based on the carbon intensity gCO2eq / kWh and the electricity consumption per kilometer kWh / km; and display the vehicle's current carbon dioxide equivalent per kilometer gCO2eq / km to the driver.

[0070] Vehicle 600 may also include a power system 602, which may include a power battery, a battery management system, an onboard charger, and an auxiliary power source. The power battery is the power source of the electric vehicle and serves as an energy storage device. Currently, pure electric vehicles primarily use lithium-ion batteries, including lithium iron phosphate batteries and ternary lithium-ion batteries. The battery management system can monitor the power battery's usage in real time, detecting power battery status parameters such as terminal voltage, internal resistance, temperature, battery electrolyte concentration, remaining battery capacity, discharge time, discharge current, or discharge depth. It also controls the temperature according to the power battery's ambient temperature requirements, uses current limiting to prevent overcharging and over-discharging of the power battery, and displays relevant parameters and alarms. Signals flow to auxiliary systems, and relevant information is displayed on the instrument cluster.

[0071] Furthermore, the vehicle 600 may also include a communication system 604 , which may be used to communicate with a charging station during charging to obtain corresponding charging information (eg, current charging progress, corresponding carbon intensity value per kWh).

[0072] Furthermore, the vehicle 600 may further include a display system 606 , which may be used to display the calculated vehicle's current CO2 equivalent per kilometer (gCO2eq / km) to the driver. In one example, the display system 606 may be a dashboard, a head-up display, or any other suitable display within the vehicle.

[0073] Additionally, the vehicle 600 may also include a sensor system 608 , a wireless transceiver 610 , a global navigation satellite system (GNSS) receiver 612 , and the like.

[0074] Sensor system 608 may include any suitable number of accelerometers, gyroscopes, and / or magnetometers. In some embodiments, sensor system 608 may be part of an inertial measurement unit (IMU) of vehicle 600. Sensor system 608 may be used to provide and / or verify motion and orientation information, monitor wheel and drivetrain performance, and / or measure the amplitude and frequency of oscillations of vehicle 400 and / or components of vehicle 600. For example, an accelerometer may measure vibrations of vehicle 600, such as movement or mechanical oscillations about the equilibrium position of components of vehicle 600. In one embodiment, the gyroscopes and magnetometers of sensor system 608 may be used to measure the vehicle's rotational state and orientation relative to magnetic north, respectively, and to measure and calibrate an estimate and / or model of the turning radius at the current speed and / or maneuverability measurements at the current speed (particularly when used in conjunction with measurements from other external and internal sensors, such as speed sensors, wheel tick sensors, and / or odometer measurements). Additionally, sensor system 608 may include radar, LIDAR, vision sensors, and the like. For example, LIDAR can provide a means of more confidently detecting the distance (and orientation) of objects, especially with respect to objects of unknown size and shape.

[0075] The wireless transceiver 610 may be configured to communicate via a short-range wireless communication protocol (e.g., ) and / or via a local area network and / or a wide area network, and / or via a cellular network, and / or via any suitable wireless network to transmit and receive data messages and elements. Of course, it should be understood that these are merely examples of networks that can be utilized by vehicle 600 over a wireless link, and the claimed subject matter is not limited in this respect. In one embodiment, wireless transceiver 610 may include various combinations of WAN, WLAN, and / or PAN transceivers. In one embodiment, wireless transceiver 610 may also include a Bluetooth transceiver, a ZigBee transceiver, or other PAN transceiver.

[0076] GNSS receiver 612 may be configured to receive and digitally process signals from navigation satellites (and / or other vehicles) to provide the receiver's position, velocity, and time. GNSS receiver 612 may include hardware and / or software components. In one embodiment, GNSS signals from GNSS satellites received by GNSS receiver 612 are used by vehicle 600 for position determination and / or for determining GNSS signal parameters and demodulated data.
