[0002] Users are often concerned about the cost of using their vehicles. Common vehicle usage costs include vehicle recharging costs and battery depreciation costs. With the development of electric vehicles, various methods for recharging the power batteries of battery vehicles have emerged. Currently, the most common methods include using home AC charging stations (commonly known as "slow charging") and using public or dedicated DC charging stations (commonly known as "fast charging"). The cost of recharging electric vehicles varies depending on the recharging method, such as fast charging or slow charging, and user usage habits. Currently, electric vehicles are not equipped with dedicated meters to measure the fast or slow charging energy of electric vehicles. Moreover, the unit prices of fast and slow charging are constantly fluctuating, making it difficult for users to calculate the recharging costs of electric vehicles in real time. Furthermore, without meters that directly display the fast or slow charging energy of electric vehicles, users cannot accurately understand battery loss and, therefore, cannot calculate the battery depreciation cost.

[0030] As used in this application and the claims, unless the context clearly indicates otherwise, the words "a," "an," "an," and / or "the" are not intended to refer to the singular but may include the plural. Generally speaking, the terms "comprises" and "include" only indicate the inclusion of the steps and elements specifically identified, and these steps and elements do not constitute an exclusive list. A method or apparatus may also include other steps or elements.

At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to actual proportional relationships. The techniques, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values should be interpreted as being merely exemplary and not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0032] In the description of this application, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction.

[0036] Figure 1 FIG. 1 is a flow chart of a vehicle usage cost calculation method 100 according to an embodiment of the present invention. The vehicle usage cost calculation method 100 is automatically executed by the vehicle. Figure 1 As shown, the vehicle usage cost calculation method 100 includes the following steps:

[0037] Step S11: Setting a virtual electric meter, which is used to collect historical energy usage information of the vehicle, including the accumulated fast charging energy, accumulated slow charging energy, and accumulated external discharge energy;

[0038] Step S12: Obtain historical energy usage information from the virtual electricity meter, and obtain cumulative mileage information and battery information from the vehicle;

[0039] Step S13: receiving charging price information, which includes slow charging price and fast charging price;

[0040] Step S14: Calculate the vehicle usage cost based on historical energy usage information, accumulated mileage information, battery information, and recharging price information.

[0041] Steps S11 to S14 are described in detail below.

[0042] In step S11, due to the limitation of the space in the vehicle console, electric vehicles are not currently equipped with special meters to count the fast charging energy or slow charging energy of electric vehicles, and the vehicle cannot automatically calculate the vehicle usage cost. The present invention sets a virtual meter to count the historical energy usage information of the vehicle without increasing the hardware cost. The virtual meter can be a statistical unit in the software. In some embodiments, the virtual meter includes a fast charging virtual meter, a slow charging virtual meter and an external discharge virtual meter. The fast charging virtual meter is used to count the cumulative fast charging energy, the slow charging virtual meter is used to count the cumulative slow charging energy, and the external discharge virtual meter is used to count the cumulative external discharge energy.

[0043] In some embodiments, the step of calculating the accumulated fast charging energy using the fast charging virtual meter includes:

[0044] Step a1: Detecting the battery status. In some embodiments, the battery status can be determined by the following steps: obtaining the battery voltage, and determining that the battery is in a fast charging state when the voltage is a charging voltage and the charging voltage is a DC voltage.

[0045] Step a2: When the battery is in a fast charge state, record the fast charge voltage, fast charge current, and fast charge time of the battery at this time, and calculate the cumulative fast charge energy based on the fast charge voltage, fast charge current, and fast charge time. In some embodiments, the fast charge virtual meter includes an integration unit, and the cumulative fast charge energy is calculated by the integration unit. Specifically, the integration unit calculates the cumulative fast charge energy using the following formula.

[0046] E DC =∑U1×I1×Δt1

[0047] Among them, E DC To accumulate fast charge energy, U1 is the fast charge voltage, I1 is the fast charge current, and Δt1 is the fast charge time.

[0048] In some embodiments, the step of calculating the accumulated slow charging energy using a virtual slow charging meter includes:

[0049] Step b1: Detecting the battery status. In some embodiments, the battery status can be detected by the following steps: obtaining the battery voltage, and determining that the battery is in a slow charging state when the voltage is a charging voltage and the charging voltage is an AC voltage.

[0050] Step b2: When the battery is in a slow charge state, record the slow charge voltage, slow charge current, and slow charge time of the battery at that time, and calculate the cumulative slow charge energy based on the slow charge voltage, slow charge current, and slow charge time. In some embodiments, the slow charge virtual meter includes an integration unit, and the cumulative slow charge energy is calculated by the integration unit. Specifically, the integration unit calculates the cumulative slow charge energy using the following formula.

[0051] E AC =∑U2×I2×Δt2

[0052] Among them, E AC To accumulate slow charging energy, U2 is the slow charging voltage, I2 is the slow charging current, and Δt2 is the slow charging time.

[0053] In some embodiments, the step of calculating the accumulated external discharge energy by the external discharge virtual meter includes:

[0054] Step c1: Detecting the battery status. In some embodiments, the battery status can be detected by the following steps: obtaining the battery voltage, and determining that the battery is in a discharging state when the voltage is a discharge voltage.

[0055] Step c2: When the battery is in a discharging state, record the discharge voltage, discharge current, and discharge time of the battery at this time, and calculate the accumulated external discharge energy based on the discharge voltage, discharge current, and discharge time. In some embodiments, the external discharge virtual meter includes an integration unit, and the accumulated external discharge energy is calculated by the integration unit. Specifically, the integration unit calculates the accumulated external discharge energy using the following formula:

[0056] E DCH =∑U3×I3×Δt3

[0057] Among them, E DCH To accumulate external discharge energy, U3 is the discharge voltage, I3 is the discharge current, and Δt3 is the discharge time.

[0058] In step S12, since the vehicle has a special odometer to count the cumulative mileage information, the cumulative mileage information can be obtained directly from the vehicle's odometer. When the vehicle leaves the factory, the vehicle's battery information is generally recorded in the vehicle's storage unit, and the battery information can be obtained directly from the vehicle's storage unit. In some embodiments, the battery information includes battery cost, number of slow charging cycles, and number of fast charging cycles. For example, the battery cost is 1,000 yuan / kWh, in yuan / kWh, and the number of slow charging cycles is 3,000 times, indicating that if the battery is only slow charged, the battery life is considered to have expired after 3,000 slow charging cycles; the number of fast charging cycles is 1,500 times, indicating that if the battery is only fast charged, the battery life is considered to have expired after 1,500 fast charging cycles.

[0059] In step S13, the energy replenishment price information is received, and the energy replenishment price information includes a slow charging price and a fast charging price. Since the energy replenishment price information fluctuates over time, it is necessary to obtain real-time energy replenishment price information. In some embodiments, the vehicle can receive the energy replenishment price information from the user's input unit, for example, the user inputs the energy replenishment price information through an input device (dashboard or touch screen), and the user can also input the energy replenishment price information through voice input of an input device (microphone). This application does not limit the way in which the user inputs the energy replenishment price information. In some other embodiments, the vehicle can receive the energy replenishment price information from the energy replenishment price website. The vehicle accesses the Internet and obtains real-time energy replenishment price information from the energy replenishment price website.

[0060] In step S14 , the vehicle use cost includes the vehicle energy recharging cost. Figure 2 FIG. 2 is a schematic diagram of a calculation process 200 for vehicle energy replenishment cost according to an embodiment of the present invention. Figure 2 As shown, the vehicle refueling cost calculation process 200 includes the following steps:

[0061] Step S21: Calculate the total vehicle refueling cost based on historical energy usage and refueling price information. For example, first calculate the average refueling price based on the refueling price and historical energy usage information. Then, add the accumulated slow charging energy to the accumulated fast charging energy, minus the accumulated external discharge energy, to obtain the final refueling energy. Multiply the average unit price by the final refueling energy to obtain the total vehicle refueling cost.

[0062] Step S22: Calculate the vehicle refueling cost based on the total vehicle refueling cost and the accumulated mileage information. In some embodiments, the vehicle refueling cost is calculated using the following formula:

[0063]

[0064] Among them, P1 is the vehicle refueling cost, E AC is the accumulated slow charging energy, E DCis the cumulative fast charge energy, E DCH is the accumulated external discharge energy, s is the accumulated mileage information, P AC is the slow charging price, P DC It’s the fast charging price.

[0065] According to the above formula, assuming the vehicle has accumulated 300kWh of fast charging, 500kWh of slow charging, 50kWh of external discharge, and a cumulative mileage of 5500km, the unit price of fast charging is 1.2 yuan / kWh, and the unit price of slow charging is 0.5 yuan / kWh. Substituting these into the above formula, the vehicle's cost of use is 0.104 yuan / km.

[0066] In some embodiments, the vehicle usage cost includes battery depreciation cost. Figure 3 FIG. 3 is a schematic diagram of a calculation process 300 of battery depreciation cost according to an embodiment of the present invention. Figure 3 As shown, the calculation process 300 of the battery depreciation cost includes the following steps:

[0067] Step S31: Calculate the battery depreciation price based on the battery information. The battery depreciation price can be obtained by dividing the battery cost by the number of battery cycles. For example, assuming the battery cost is 1,000 yuan / kWh and the number of slow charging cycles is 3,000, the depreciation price of the slow charging battery is approximately 0.33 yuan / kWh (1,000 yuan / kWh / 3,000); if the number of fast charging cycles is 1,500, the depreciation price of the fast charging battery is approximately 0.66 yuan / kWh (1,000 yuan / kWh / 1,500).

[0068] Step S32: Obtain the battery depreciation cost based on the historical energy usage information and the battery depreciation unit price. In some embodiments, the battery depreciation cost is calculated using the following formula:

[0069]

[0070] Among them, P2 is the battery depreciation cost, E AC is the accumulated slow charging energy, E DC is the cumulative fast charge energy, P B is the battery cost, N1 is the number of slow charging cycles, and N2 is the number of fast charging cycles.

[0071] The vehicle usage cost calculation method of the present invention uses a virtual electricity meter to collect historical energy usage information of the vehicle, and automatically calculates the vehicle usage cost based on the historical energy usage information, cumulative mileage information, battery information and energy replenishment price information, so that users can intuitively understand the vehicle usage cost and solve the problem of opaque vehicle usage cost; the present invention does not require additional hardware costs under existing conditions, and the method has low implementation cost.

[0072] Figure 4FIG is a system block diagram of a vehicle-mounted automatic calculation device 400 for vehicle usage cost according to an embodiment of the present invention. Figure 4 As shown, the onboard automatic computing device 400 may include an internal communication bus 401, a processor 402, a read-only memory (ROM) 403, a random access memory (RAM) 404, a communication port 405, and an interface port 406. The internal communication bus 401 can enable data communication between the components of the onboard automatic computing device 400. The processor 402 can perform calculations and feedback calculation results. The communication port 405 can enable data communication between the onboard automatic computing device 400 and the outside world. In some embodiments, the onboard automatic computing device 400 can send and receive information and data from the network through the communication port 405. The interface port 406 can obtain input information from the external input device 10. For example, when the input device 10 is a dashboard or a touch screen, the interface port 406 obtains energy replenishment price information from the dashboard or touch screen; when the input device 10 is a microphone, the interface port 406 obtains energy replenishment price information from the microphone. The vehicle-mounted automatic calculation device 400 may also include various forms of program storage units and data storage units, such as a read-only memory (ROM) 403 and a random access memory (RAM) 404, capable of storing various data files used for computer processing and / or communication, as well as possible program instructions executed by the processor 402. The processor executes these instructions to implement the main part of the method. The above-mentioned operating method can be implemented as a computer program, stored in the read-only memory (ROM) 403, and loaded into the processor 402 for execution to implement the vehicle usage cost calculation method of the present application.

[0073] In some embodiments, the vehicle-mounted automatic calculation device 400 may further include a display unit 407. Processor 402 transmits processing results to display unit 407 via internal communication bus 401, where the processing results are displayed. For example, processor 402 transmits acquired historical energy usage information to display unit 407 via internal communication bus 401, allowing users to visually view the vehicle's accumulated charging energy. This facilitates second-hand vehicle transactions by providing additional reference information beyond the accumulated mileage displayed on the meter, facilitating information disclosure and promoting transactions in the used vehicle market.
