Description

Technical Field

[0001] The present invention belongs to the technical field of vehicle battery replacement, and specifically relates to a vehicle battery replacement rental billing method, device, and system. Background Art

[0002] Battery-swap heavy trucks can quickly complete battery swaps and recharges at battery swap stations, greatly reducing vehicle waiting time and improving vehicle operating efficiency. Battery asset operators are mainly involved in the leasing and management of power batteries for electric vehicles. Their core business is to provide leasing services to battery swap operators or directly to electric heavy truck drivers. Currently, battery asset management operators charge battery rental fees mainly through metering and billing the charging power of the battery box at the battery swap station and the SOC value difference between the battery box before and after the battery swap of the battery swap heavy truck.

[0003] Method 1: The battery pack of an electric heavy-duty truck is charged at a battery swap station. Settlement begins when the battery pack is fully charged. The charging entity is the charger, and settlement is based on the meter reading on the charger's DC output. This method cannot achieve real-time billing and settlement for battery pack swaps. Settlement cannot be completed until the driver's replaced battery pack is fully charged at the battery swap station. This results in billing time lags, a poor user experience, and requires driver authorization for deductions. This method is not conducive to the promotion of the vehicle-battery separation business model.

[0004] Method 2: The settlement is made by subtracting the SOC difference between the SOC value when the battery box is replaced on the electric heavy-duty truck and the SOC value when the battery box is replaced. The data of this method is derived from the evaluation value of the battery management system in the battery box. It is not measured by legal instruments and has the disadvantage of large measurement deviation. It is unreasonable to use it as a billing basis.

[0005] At the same time, electric heavy trucks currently have conditions where kinetic energy is fed back during driving. The vehicles also have the function of feeding back electricity. Especially in the scenario of heavy-loaded downhill driving, the energy fed back is very large and can even fully fill the battery box. This makes the existing metering and billing settlement methods unreasonable. For the power battery box, it has already undergone a cycle of charge and discharge and consumed a cycle life. Summary of the Invention

[0006] The purpose of the present invention is to provide a vehicle battery swap rental billing method, device and system to solve the technical problem in the prior art that the battery swap rental fee does not take into account charging events outside the battery swap station, resulting in an unreasonable billing method.

[0007] In order to solve the above technical problems, the present invention provides a technical solution for a vehicle battery swap rental billing method: a vehicle battery swap rental billing method, the method comprising:

When the present invention is billing the battery swap rental, in addition to the power battery box loss caused by the normal power consumption of the power battery box, the power battery box loss caused by the charging events outside the battery swap station (that is, the charging amount of the charging pile outside the battery swap station and the feedback amount of the vehicle energy feedback device) is also taken into account. The battery loss caused by a single lease is measured more reasonably, and the billing strategy is optimized, making the billing method more reasonable and effectively protecting the legitimate rights and interests of the battery asset manager.

BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Figure 1 This is a schematic diagram of the system composition of an embodiment of the vehicle battery swap rental billing system of the present invention;

[0025] Figure 2 This is a schematic diagram of the billing process of the vehicle battery replacement rental billing system implementation method of the present invention. DETAILED DESCRIPTION

[0026] When charging for battery swapping leases, the present invention not only takes into account the power battery box loss caused by normal power consumption, but also takes into account the power battery box loss caused by charging events outside the battery swap station (i.e., the charging amount of the charging pile outside the battery swap station and the feedback amount of the vehicle energy feedback device). This makes the measurement of battery loss caused by a single lease more reasonable, thereby optimizing the billing strategy, making the billing method more reasonable, and effectively protecting the legitimate rights and interests of the battery asset manager. The present invention solves the technical problem in the prior art that battery swapping lease fees do not take into account charging events outside the battery swap station, resulting in an unreasonable billing method.

[0027] Implementation method of vehicle battery swap rental billing system:

[0028] A vehicle battery replacement rental billing system, such as Figure 1 As shown, it includes an intelligent control terminal, a high-voltage metering box, a signal acquisition terminal and a high-voltage box installed on the power battery box. The high-voltage box integrates the positive and negative terminals of multiple battery modules in the power battery box (i.e., the positive and negative poles of the battery modules), and connects the terminals in series and parallel to obtain the desired voltage and current of the power battery box. The signal acquisition terminal collects the DC voltage on both sides of the high-voltage busbar of the power battery box through parallel voltage divider resistors. The DC voltage V on both sides of the busbar is DC The voltage is converted into a low voltage signal V by the voltage divider resistors R1 and R2 low .

[0029]

[0030] The physical quantity of the DC current flowing through the bus is collected by inserting a shunt in series. The DC current IDC flowing through the bus generates a small voltage drop Vshunt through the shunt Rshunt. This voltage is proportional to the current.

[0031] V shunt =I DC ×R shunt

[0032] Therefore, the DC+ / DC- voltage signal and current signal on the DC output bus are converted into low-voltage acquisition signals through the voltage divider resistor and shunt and transmitted to the high-voltage metering box.

[0033] The high-voltage metering box controller calculates the real-time power P through the transmitted digital signal and the gain of the hardware acquisition circuit, and then obtains the charging and discharging power of different events through digital integration operations.

[0034] The real-time power calculation formula is as follows:

[0035]

[0036] The calculation formulas for charging and discharging power are as follows:

[0037] E=∫P(t)dt

[0038] The high-voltage metering box transmits the charge and discharge information of different events to the intelligent control terminal via 485 serial port communication. The intelligent control terminal determines the business logic status of a single battery swap of the battery swap vehicle and identifies different types of metering tasks, including loading and unloading of the power battery box, charging at the charging pile outside the battery swap station, and charging of the energy feedback device. Based on different metering tasks, the difference between the power battery box's charge when loading and unloading, the charge amount of the charging pile outside the battery swap station, and the feedback power of the vehicle's energy feedback device are obtained. The difference between the power battery box's charge when loading and unloading, the charge amount of the charging pile outside the battery swap station, and the feedback power of the vehicle's energy feedback device are then added together to obtain the single-cycle power. When a battery box loading and unloading action is completed, the single charge and discharge data (i.e., single-cycle power) is automatically generated and pushed to the battery box asset management platform via 4G / 5G signals. The battery box asset management platform completes the real-time metering and billing function of the vehicle's battery swap through the metering and billing settlement strategy (i.e., the vehicle battery swap rental billing method).

[0039] It should be noted that the battery box asset management platform represents the owner of the power battery box, not the battery swap station. Therefore, the billing method of the present invention is the loss fee charged by the battery box asset management platform during the use of the power battery box, and does not involve the electricity charges generated by charging in the battery swap station and other fees charged by the battery swap station.

[0040] like Figure 2 As shown, the metering and billing process of the vehicle battery replacement rental billing method of this embodiment is as follows:

[0041] 1) The battery-swapping heavy truck enters the battery-swapping station and starts the battery-swapping operation;

[0042] 2) The on-site spare power battery box is loaded onto the vehicle at the battery swap station;

[0043] 3) The battery box intelligent control terminal in the power battery box detects the battery loading event in the station and starts the metering task;

[0044] 4) The high-voltage metering box in the power battery box collects the initial value Ms of power measurement when the power battery box is loaded on the vehicle in real time;

[0045] 5) The high-voltage metering box transmits the starting metering value of the power battery box to the intelligent control terminal via serial port 485 communication;

[0046] 6) During vehicle operation, the high-voltage metering box measures the vehicle's charging and discharging voltage and current in real time;

[0047] 7) The high-voltage metering box collects the charging power M1 of the off-site charging pile during vehicle operation;

[0048] 8) The high-voltage metering box collects the amount of electricity M2 that is reversely charged to the battery box by the braking energy feedback system during vehicle operation;

[0049] 9) The heavy truck completes its production and operation activities and enters the battery swap station to start the battery swap operation;

[0050] 10) The battery box on the battery swapping vehicle completes the unloading operation at the battery swapping station;

[0051] 11) The high-voltage metering box in the power battery box collects the end metering value Me of the power battery box in real time, and obtains the total battery power reduction value Mr = the starting metering value Ms of the battery box on the vehicle - the end metering value Me of the battery box off the vehicle;

[0052] 12) The current measurement value (the total battery power reduction value Mr) is transmitted to the intelligent control terminal via the serial port 485 communication method;

[0053] 13) The intelligent control terminal detects the battery box unloading event and generates a single battery rental billing event;

[0054] 14) Start the metering strategy to calculate the battery single cycle power, battery single cycle power Mc = battery total power reduction value Mr + off-site charging pile charging power M1 + energy feedback power M2;

[0055] 15) The intelligent control terminal generates a single cycle of battery power and sends it to the battery box asset management platform via 4G / 5G;

[0056] 16) The battery box asset management platform starts the settlement strategy based on the single cycle power and the operator-set electricity rental fee C to calculate the single battery rental fee S, which is battery rental fee S = battery single cycle power Mc * electricity rental fee service fee C;

[0057] 17) The battery box asset management platform performs billing and settlement for the transportation users based on billing events and battery rental fees, and outputs a settlement statement.

[0058] In other implementations, other billing strategies may be used, such as a tiered pricing strategy: as the power consumption per cycle increases to a certain range, the power rental fee and service fee may also be adjusted accordingly. Or other types of billing methods may be used.

[0059] In other embodiments, the intelligent control terminal may also be provided inside the power battery box. It only needs to be integrated with the power battery box to ensure that the data collected by the high-voltage metering can be stably received.

[0060] In other embodiments, the intelligent control terminal may not be set on the power battery box, but on the vehicle, and may not be put on or off the vehicle with the power battery box. When the power battery box is put on the vehicle, the high-voltage metering box on the power battery box is communicatively connected to the intelligent control terminal; when the power battery box is unloaded from the vehicle, the communication connection between the high-voltage metering box and the intelligent control terminal is disconnected.

[0061] Implementation method for vehicle battery replacement leasing billing method:

The specific vehicle battery swap rental billing method has been described in sufficient detail in the aforementioned vehicle battery swap rental billing system and will not be repeated here.

[0063] Specifically, the rental fee for this vehicle battery replacement is the product of the single-cycle electricity consumption and the electricity rental service fee.

[0064] Implementation method of vehicle battery replacement rental billing device:

[0065] A vehicle battery swap rental billing device includes a processor configured to execute a computer program to implement the steps of the vehicle battery swap rental billing method described above. The specific vehicle battery swap rental billing method has been described in sufficient detail in the vehicle battery swap rental billing system described above and will not be repeated here.

[0066] Specifically, the processor may be a CPU, or other general-purpose processor, a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. A general-purpose processor may be a microprocessor or any conventional processor, etc. The processor may also be a processor that supports the Advanced RISC Machine (ARM) architecture.

[0067] It should be noted that the processor here can be the processor of the battery box asset management platform or the processor of the battery swap station management platform.

[0068] The main difference between this embodiment and the above-mentioned vehicle battery swap rental billing system is that the intelligent control terminal no longer processes the data collected by the high-voltage meter box, but sends the data collected by the high-voltage meter box directly to the platform where the processor of this embodiment is located (battery box asset management platform or battery swap station management platform). The platform's processor calculates and processes the data collected by the high-voltage meter box to obtain the difference between the power when getting on the vehicle and the power when getting off the vehicle, the charging amount of the charging pile outside the battery swap station, and the feedback power of the vehicle energy feedback device, and further charges according to the preset billing strategy.

[0069] The present invention has the following characteristics:

[0070] In the business model of heavy truck battery swapping and vehicle-to-vehicle separation, the collection of battery rental requires real-time and accurate measurement of the vehicle's charging and discharging power. The above-mentioned settlement scheme in the embodiment of the present invention can firstly realize real-time and effective settlement when the battery box is replaced and the vehicle is unloaded, which is convenient for realizing the billing model of off-vehicle settlement; secondly, it has the ability to dynamically measure and bill for the charging and swapping of battery boxes through unconventional means outside the battery swap station operated by the asset manager, effectively protecting the legitimate rights and interests of the battery asset manager; it can judge the battery's on-board and off-vehicle status and collect the charging and discharging amount without relying on the battery swap station, and can separate the settlement of the battery swap service fee of the battery swap station and the settlement of the battery rental service fee of the battery asset manager, simplifying the settlement logic and facilitating the interconnection of multiple stations of different battery swap station operators sharing the same battery asset manager.

[0071] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments without inventive effort, or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
