[0001] The present application relates to the field of vehicle technology, and in particular to a new energy vehicle workshop charging method, system, computer equipment and storage medium. Background Art

[0002] The bidirectional charging technology of new energy vehicles can be used in a variety of scenarios. For example, V2G (Vehicle-to-Grid) technology uses new energy vehicles as distributed power sources, feeding the stored electricity back to the grid to provide energy support for the grid; V2H (Vehicle-to-Home) technology feeds the stored electricity on new energy vehicles back to the home grid to power the home; V2B (Vehicle-to-building) technology feeds the stored electricity on new energy vehicles back to the grid of commercial buildings to power commercial buildings.

[0003] V2V (Vehicle-to-Vehicle) technology can transmit electricity between new energy vehicles to achieve power sharing. Based on this technology, road rescue of new energy vehicles can be realized.

[0004] However, when new energy vehicles are currently performing road rescue, the issue of the return range of discharged vehicles is not taken into consideration. Drivers are required to estimate the discharge amount on their own. Inaccurate estimates can easily result in discharged vehicles being unable to reach their destination, causing trouble for users.

When the total actual charge amount is greater than the total externally chargeable amount, at least one first restrictive vehicle is determined from the vehicles to be charged to remove the first restrictive vehicle from the group.

[0051] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0052] The new energy vehicle workshop charging method provided in this application can be applied to Figure 1 In the application environment shown, the terminal 102 communicates with the server 104 via the network.

[0053] The computing cloud platform composed of server 104 obtains various parameters collected by the terminal and performs calculations. The terminal 102 can be, but is not limited to, various personal computers, laptops, smartphones, tablet computers, portable wearable devices, and vehicle-mounted terminals. The server 104 can be implemented as a standalone server or a server cluster composed of multiple servers.

[0054] In one embodiment, Figure 2 As shown, a new energy vehicle workshop charging method is provided, which is applied to Figure 1 The following steps are used as an example to illustrate the server in the example:

[0055] Step 201, parameter acquisition, includes acquiring energy parameters and energy consumption parameters of each member in the group, wherein the energy parameters include the actual remaining amount of energy, and the energy consumption parameters include unit energy consumption. The members include the discharged vehicles and the vehicles to be charged in the group.

[0056] In actual implementation, the workshop charging method provided in this embodiment can be applied to energy coordination and charging rescue in a fleet including multiple new energy vehicles. There may be one or more vehicles in the fleet serving as discharging vehicles, and correspondingly, there may be one or more vehicles with insufficient energy and become vehicles to be charged.

[0057] It can be understood that the group can be created in response to a creation request from a discharging vehicle or a vehicle to be charged. Before the rescue, the cloud receives the creation request from the vehicle side, creates a group for it, and assigns a special code number to the created group as a group identifier. Other members join the group by searching for the group identifier. When joining the group, all members package their own information and upload it to the cloud and update it in real time. The information includes vehicle identification, current coordinates, needs (rescue or waiting for rescue), energy type, actual remaining amount of each energy type (such as the remaining power of pure electric vehicles, the remaining power and fuel level of extended-range vehicles), unit energy consumption (energy consumption per kilometer or energy consumption per 100 kilometers. For the convenience of explanation, the unit energy consumption uses energy consumption per kilometer), vehicle driving mode, etc.

[0058] Step 202 : Obtain the destination coordinates of each member, and obtain the expected driving mileage of each member based on the destination coordinates and the charging location coordinates.

[0059] For each member of the fleet, the destination coordinates can be set by the driver. Click the destination setting on the vehicle side, and the navigation interface will pop up. The driver can enter the destination or search for the destination on the map, and then determine the destination coordinates from the electronic map and upload them to the cloud.

[0060] Among them, the destinations of different members may be different, such as Figure 3 As shown, A1 and A2 in the fleet are discharging vehicles, and B1 is a vehicle to be charged. For the discharging vehicles A1 and A2, after being rescued from the charging location s, their respective remaining energy needs to support them to reach their respective destinations d1 and d2. For the vehicle to be charged B1, after receiving rescue at the charging location s, it can leave the fleet to find the nearest energy station d3 (charging pile or gas station).

[0061] For example, the coordinates of the charging location are generally the current coordinates of the vehicle to be charged; when there are multiple vehicles to be charged, the driver can use the vehicle navigation system to find a suitable charging location (such as a parking lot, a wide area, etc.) within the distribution range of the vehicles to be charged. After the fleet arrives at the charging location, a group is created to carry out rescue. The vehicle end of the vehicle to be charged can then upload the coordinates of the charging location to the cloud.

[0062] After obtaining the coordinates of the destination and the charging site, the cloud can use the navigation system to determine the navigation path from the charging site to the destination and calculate the length of the navigation path as the expected mileage of the vehicle.

[0063] Step 203: Obtain the expected energy value of each member according to the expected driving mileage and energy consumption parameters of each member.

[0064] It can be understood that the energy consumption parameters can be calculated based on the historical energy consumption data of each member, and the energy required to travel from the charging point to the destination can be reversed based on the expected mileage and energy consumption parameters. Generally, when the expected energy value of the vehicle is met, the vehicle can reach the destination.

[0065] Step 204 : calculating the additional energy demand of the vehicles to be charged, including obtaining the amount to be charged according to the expected energy value and the actual remaining amount of each vehicle to be charged.

[0066] It should be pointed out that the rescue method for new energy vehicles in this application is mainly to replenish power. Even for extended-range vehicles, when it is estimated that the remaining power and remaining oil are not enough to support reaching the destination, it can join the group to seek power replenishment.

[0067] If the vehicle to be charged is a pure electric vehicle or a range-extended vehicle with zero fuel consumption, the subsequent driving process will only consume electricity. The expected power can be calculated based on the expected mileage and power consumption per kilometer. The expected power minus the actual remaining power is the amount to be charged;

[0068] If the vehicle to be charged is an extended-range vehicle with non-zero fuel, and part of the mileage in the subsequent driving process is completed by switching from oil to electricity, the fuel-driven mileage can be first calculated based on the actual remaining fuel and the fuel consumption per kilometer, and then the fuel-driven mileage can be deducted from the expected driving mileage to obtain the electric-driven mileage, thereby obtaining the expected power. The expected power minus the actual remaining power is the power to be charged.

[0069] It should be pointed out that although part of the electricity will be used to replenish the battery pack during the operation of the range extender, when this electricity is used to drive the vehicle or for external charging, it is still regarded as fuel consumption.

[0070] During the V2V charging process, electric energy passes through the bidirectional chargers of the discharging vehicle and the vehicle to be charged, and is limited by the battery pack charging efficiency (the ratio of discharged power to charged power), so there is power loss during the rescue process. Therefore, after calculating the amount to be charged, the actual charging amount required for each vehicle to be charged is determined based on the amount to be charged and the external charging loss ratio. The external charging loss ratio can be calibrated according to the actual vehicle, and the actual charging amount is used for subsequent comparison to obtain more accurate results.

[0071] On the other hand, step 204 further calculates the surplus amount of energy for the discharging vehicles, including obtaining the externally chargeable amount according to the expected energy value and the actual remaining amount of each of the discharging vehicles.

[0072] Similar to the calculation process of additional demand, if the discharging vehicle is a pure electric vehicle or an extended-range vehicle with zero fuel, and the V2V process and subsequent driving process only involve power consumption, the expected power can be calculated based on the expected mileage and unit power consumption, and the actual remaining power can be subtracted from the expected power to obtain the externally chargeable amount.

[0073] If the discharging vehicle is an extended-range vehicle with non-zero fuel, the V2V process and subsequent driving process involve fuel consumption. At this time, when determining the external chargeable amount of the extended-range vehicle in the discharging vehicle, it is necessary to determine the V2V strategy based on the driver's wishes.

[0074] For example, if the driver of a discharging vehicle sets the fuel priority mode and hopes to retain more power, the power cutoff value is higher, such as 80% power; if the driver sets the pure electric priority mode and hopes to retain more oil, the power cutoff value is lower, such as 20%. During the V2V process or driving, whenever the battery pack power drops to the power cutoff value, the range extender will be started for external charging or driving. When the cloud obtains the driving mode of the vehicle, it determines the power cutoff value of the vehicle accordingly. First, the power cutoff value is subtracted from the actual remaining power (generally, the actual remaining power is greater than the power cutoff value) to obtain the first externally chargeable amount of the extended-range vehicle. The first externally chargeable amount is the power released by the battery pack.

[0075] Then, the reserved fuel amount is determined based on the power cutoff value, the unit power consumption, the expected mileage, and the unit fuel consumption. Specifically, assuming that in the fuel priority mode, 80% of the power of the power cutoff value will be completely consumed during the subsequent driving process, the mileage that can be traveled with 80% of the power can be determined based on the unit power consumption. After subtracting this part from the expected mileage, the remaining mileage is the shortest fuel-driven mileage. The excess fuel can be used for external charging rescue. The fuel amount corresponding to the fuel-driven mileage can be reversed based on the unit fuel consumption, which is the reserved fuel amount.

[0076] Afterwards, the amount of external fuel available for external charging can be determined based on the actual remaining fuel amount minus the reserved fuel amount. Based on the external fuel amount and the oil-to-electricity conversion rate, the second externally chargeable amount of the extended-range vehicle can be obtained. The sum of the first externally chargeable amount and the second externally chargeable amount is the externally chargeable amount of the extended-range vehicle.

[0077] The oil-to-electricity conversion rate (the amount of electricity converted from every 1L of fuel, in kWh) can be calibrated through bench tests, and the range is generally 2.70-3.29. In actual implementation, the oil-to-electricity conversion rate is mainly affected by the oil temperature, the fuel pressure in the fuel pipe, and the speed. Therefore, a bench test can be carried out to measure the oil-to-electricity conversion rate from the engine to the generator output end at different oil temperatures, fuel pressures in the fuel pipe, and speeds. The temperature, fuel pressure in the fuel pipe, speed, and corresponding oil-to-electricity conversion rate obtained from the test are then fitted to obtain the corresponding mapping relationship between the oil-to-electricity conversion rate and the oil temperature, fuel pressure in the fuel pipe, and speed. The mapping relationship is stored and can be searched and called based on the current oil temperature, fuel pressure in the fuel pipe, and speed when applied.

[0078] After determining the additional demand for vehicles to be charged and the excess capacity of vehicles to be discharged, you can proceed to the next step.

[0079] Step 205 : Match at least one of the discharging vehicles from the group to the vehicle to be charged based on the comparison between the actual charge capacity and the externally chargeable capacity, so that the discharging vehicle performs vehicle-to-vehicle charging rescue based on the externally chargeable capacity.

[0080] For example, Figure 4 As shown, after the actual charge capacity of the vehicle to be charged and the external charge capacity of the discharge vehicle are clearly determined, the identification of the vehicle to be charged, the corresponding actual charge capacity, the identification of the discharge vehicle, and the corresponding external charge capacity can be sent to the vehicle end for display, and the driver can choose the combination of the discharge vehicle and the vehicle to be charged, or the cloud can perform the pairing and send the pairing result to each member. The principle of combination pairing is to select a discharge vehicle with an external charge capacity greater than or equal to the actual charge capacity for rescue. If there is no discharge vehicle with an external charge capacity greater than or equal to the actual charge capacity or the discharge vehicle that meets this condition is occupied by other vehicles, multiple discharge vehicles with an external charge capacity less than the actual charge capacity can be selected as rescue vehicles for the current vehicle to be charged, and let them take turns to recharge the vehicle to be charged.

[0081] The discharging vehicle performs vehicle-to-vehicle charging based on the externally chargeable amount. The externally chargeable amount gradually decreases as the external charging rescue progresses. When it reaches zero, the vehicle end automatically stops external discharging to prevent excessive external discharge from causing the vehicle to be unable to complete the journey.

[0082] In the above pairing process, it is assumed that the energy of the discharged vehicle is sufficient to replenish the actual power of all vehicles to be charged. However, in the actual implementation process, it is inevitable that the total energy is insufficient, so it is necessary to formulate an abandonment strategy when rescue is impossible.

[0083] Exemplarily, the cloud obtains the total actual charge amount based on the actual charge amount of each of the vehicles to be charged; obtains the total externally chargeable amount based on the externally chargeable amount of each of the vehicles to be discharged; compares the total actual charge amount with the total externally chargeable amount, and when the total actual charge amount is greater than the total externally chargeable amount, a prompt of insufficient total amount can be sent to the vehicle end of the member, and the driver can selectively give up rescue from the current vehicles to be charged, for example, determine the vehicle to be charged with the largest additional demand as the first restrictive vehicle that needs to be abandoned, and remove it from the group.

[0084] In the above embodiment, the workshop charging method is applied to energy distribution in a fleet. The distance between the discharged vehicles and the rescued vehicles in the same fleet is short, and rescue is convenient. The workshop charging method provided in this application can also be used to seek rescue from unfamiliar vehicles within a certain distance.

[0085] For example, in one embodiment, when the driver of a vehicle to be charged predicts that his or her own energy cannot complete the intended journey, he or she initiates a rescue request to the cloud. The cloud creates a group based on the rescue request and forwards the rescue request to other vehicles within a certain distance around the vehicle to be charged. Other vehicles can then join the group after confirmation.

[0086] After that, the vehicle to be charged can choose a drivable location as the charging location, and the discharging vehicle can drive to the charging location. In one embodiment, the cloud can determine one or more possible charging locations for the driver to choose from the original path between the current coordinates and the destination coordinates based on the remaining mileage of the vehicle to be charged. Selecting a charging location from the original path can reduce the yaw distance of the vehicle to be charged, thereby reducing the external charging amount of the discharging vehicle and reducing V2V loss.

[0087] In one embodiment, the cloud obtains the original path of the vehicle to be charged, and plans a rescue path for the discharged vehicle from the current coordinates to the original path based on the current coordinates of the discharged vehicle, and determines the intersection of the rescue path with the shortest distance and the original path as the rescue point. The coordinates of the intersection are used as the coordinates of the rescue point in subsequent calculations, thereby saving energy consumption of the discharged vehicle.

[0088] In the outbound call for help method, the discharged vehicle may need to travel a certain distance to reach the charging site. The energy consumed in this distance may result in insufficient rescue energy or inability to return to the intended destination after rescue. Therefore, before obtaining the expected mileage of each member based on the destination coordinates and the charging site coordinates, it also includes obtaining the current coordinates and the remaining mileage of the discharged vehicle in the group. The remaining mileage can be calculated based on the remaining energy and historical energy consumption; obtaining a first expected mileage based on the current coordinates and the charging site coordinates; obtaining a second expected mileage based on the destination coordinates and the charging site coordinates; determining a discharged vehicle whose sum of the first expected mileage and the second expected mileage is greater than the remaining mileage of the discharged vehicle as a second restricted vehicle, so as to remove the second restricted vehicle from the group.

[0089] Vehicles with insufficient rescue energy or unable to return to the intended destination after rescue are excluded from the group, effectively avoiding the occurrence of secondary rescue.

[0090] It should be understood that although Figure 1 The steps in the flowchart are shown in sequence as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this document, there is no strict order restriction for the execution of these steps, and these steps can be executed in other orders. In addition, Figure 1 At least part of the steps may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily executed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least part of the sub-steps or stages of other steps.

[0091] In one embodiment, Figure 5 As shown, a new energy vehicle workshop charging system is provided, including: an acquisition module 301, a calculation module 302 and a matching module 303, wherein:

[0092] Acquisition module 301 is used to acquire parameters of each member in the group, including energy parameters, energy consumption parameters, and coordinate parameters of each member. The energy parameters include the actual remaining amount of energy, the energy consumption parameters include the unit energy consumption, and the coordinate parameters include the coordinates of the charging location and the coordinates of the member's destination. The member includes the discharged vehicles and the vehicles to be charged in the group.

[0093] Calculation module 302 is configured to obtain an expected driving range for each member based on the destination coordinates and the charging location coordinates, and obtain an expected energy value for each member based on the expected driving range and energy consumption parameters. Thereafter, the remaining charge capacity is obtained based on the expected energy value and the actual remaining capacity of each vehicle to be charged, and the available external charge capacity is obtained based on the expected energy value and the actual remaining capacity of each vehicle to be discharged. Furthermore, the actual charge capacity required for each vehicle to be charged is determined based on the remaining charge capacity and the external charge loss ratio.

[0094] The matching module 303 is configured to match at least one of the discharging vehicles from the group with the vehicle to be charged based on the comparison between the actual charged capacity and the externally chargeable capacity, so as to perform vehicle-to-vehicle charging rescue.

[0095] In one embodiment, when acquiring energy parameters, the acquisition module 301 includes acquiring the actual remaining power of all members in the group and the actual remaining fuel of the extended-range vehicles among the members; when acquiring energy consumption parameters, the unit power consumption of all members and the unit fuel consumption of the extended-range vehicles among the members are acquired, so that the calculation module 302 can calculate the amount of charge to be charged of the extended-range vehicles among the vehicles to be charged, and the amount of external charge that can be charged of the extended-range vehicles among the discharging vehicles.

[0096] When calculating the externally chargeable capacity of the extended-range vehicle among the discharging vehicles, the calculation module 302 obtains a first externally chargeable capacity of the extended-range vehicle according to the capacity cutoff value and the actual remaining capacity;

[0097] The amount of externally consumed fuel available for external charging is determined based on the reserved fuel amount and the actual remaining fuel amount. The second externally charged amount of the extended-range vehicle is obtained based on the externally consumed fuel amount and the oil-to-electricity conversion rate. The sum of the two is the externally charged amount.

[0098] In one embodiment, the calculation module 302 further obtains the total actual charge capacity according to the actual charge capacity of each of the vehicles to be charged; and obtains the total externally chargeable capacity according to the externally chargeable capacity of each of the discharging vehicles.

[0099] The matching module 303 compares the total actual charge amount and the total external charge amount. When the total actual charge amount is greater than the total external charge amount, the matching module 303 removes at least one vehicle from the vehicles to be charged so that the total actual charge amount of the remaining members is less than or equal to the total external charge amount.

[0100] In one embodiment, the workshop charging system provided in the present application is used to ask for help from an unfamiliar vehicle and verify the energy level of the unfamiliar vehicle before it drives to the charging site. Specifically, the acquisition module 301 obtains the current coordinates and the remaining mileage of the discharged vehicle in the group; the calculation module 302 obtains the first expected mileage based on the current coordinates and the charging site coordinates; and obtains the second expected mileage based on the destination coordinates and the charging site coordinates; if the sum of the first expected mileage and the second expected mileage is greater than the remaining mileage of the discharged vehicle, it can be removed and no longer used as a discharged vehicle.

[0101] When matching a discharging vehicle with a vehicle to be charged, the matching module 303 may use a discharging vehicle with a chargeable capacity greater than or equal to the actual charge capacity as a rescue vehicle for the vehicle to be charged, or use multiple discharging vehicles with a chargeable capacity less than the actual charge capacity as rescue vehicles for the vehicle to be charged.

[0102] In one embodiment, the acquisition module 301 obtains the coordinates of the charging location from the planned path of the navigation system. Specifically, the navigation system plans a path between the current coordinates of the vehicle to be charged and the coordinates of the destination, and the acquisition module 301 selects a location on the path within the driving range of the vehicle to be charged as the charging location.
