Description

TECHNICAL FIELD

[0002] With the development of science and technology and the strengthening of people's environmental protection awareness, electric vehicles are increasingly favored by people.

[0003] At present, when an electric vehicle is parked, a small irregular current discharge occurs due to the operation of high-power components (such as a vehicle-mounted refrigerator or components associated with a sentinel mode), thereby generating static power consumption. Since the small irregular current discharge is not easy to be monitored, the SOC displayed at the initial moment when the electric vehicle is restarted is still the SOC before parking. After the electric vehicle travels for a period of time, the SOC is automatically corrected in combination with the previous static power consumption, resulting in a jump in the SOC and causing the user's range anxiety and even causing the electric vehicle to break down while traveling.

[0006] In some embodiments, the step of determining the average power consumption of each time of parking of the electric vehicle in history based on the identity information of the electric vehicle comprises the following steps. based on the identity information of the electric vehicle, obtaining average parking duration, driving habit features associated with parking power consumption and basic power consumption per unit time of each time of parking of the electric vehicle in history; determining additional power consumption per unit time of the electric vehicle according to the driving habit features associated with the parking power consumption; The base power consumption per unit time is compared with the additional power consumption of the electric vehicle per unit time. The sum of these is determined as the total power consumption of the electric vehicle per unit time. The average power consumption of an electric vehicle during each historical period of stationary parking is determined based on the average stationary parking time of the electric vehicle and the total power consumption of the electric vehicle per unit time.

[0007] In some implementations, vehicle usage habits associated with idle power consumption include the percentage of times Sentinel mode is used and the percentage of times the refrigerator is used. Based on these usage habits associated with idle power consumption, the additional power consumption per unit time of the electric vehicle is determined, including: If the percentage of times the Sentinel mode is used exceeds the set percentage threshold, obtain the power consumption of the electric vehicle in Sentinel mode per unit time. If the percentage of times the refrigerator is used exceeds a set threshold, obtain the power consumption of the refrigerator per unit time. The sum of the power consumption of the electric vehicle in Sentinel mode per unit time and the power consumption of the refrigerator per unit time is determined as the additional power consumption of the electric vehicle per unit time.

[0008] In some implementations, the average power consumption of the electric vehicle during each historical period of stationary parking is determined based on the electric vehicle's identity information, including: Based on the electric vehicle's identification information, the system retrieves the actual power consumption of the electric vehicle during each historical period of stationary parking from a pre-set database. The average power consumption of electric vehicles during each historical period of stationary parking is determined based on the actual power consumption of the electric vehicles during each historical period of stationary parking.

[0009] In some embodiments, the method provided in this application further includes: When the average power consumption exceeds a set power threshold, the electric vehicle's identity information is marked. Receive a SOC anomaly query command from the customer service terminal, wherein the SOC anomaly query command... It contains the vehicle owner's identification information; If the identity information of the electric vehicle associated with the owner's identity information is marked, the marked electric vehicle's identity information will be sent to the customer service terminal.

[0010] In some implementations, the SOC calibration reminder is a prompt instructing the vehicle owner to slow charge the electric vehicle to 100%.

[0011] In some implementations, a reminder message for SOC correction is sent to the user terminal associated with the electric vehicle's identity information, including: From the pre-set database, query the frequently used times associated with the electric vehicle's identity information; When the current time arrives at the usual time for vehicle use or when the electric vehicle is detected to be charging, a reminder message for SOC correction is sent to the user terminal associated with the electric vehicle's identity information.

It can receive parking commands uploaded by the electric vehicle, which carry the vehicle's identification information. Understandably, during parking, electric vehicles generate continuous, irregular small-current discharges that are difficult to detect, resulting in a certain amount of parking power consumption. Therefore, based on the electric vehicle's identification information, the average power consumption of the electric vehicle during its historical parking periods can be determined. This average power consumption can characterize the power consumption of the electric vehicle during the current parking period. If the average power consumption exceeds a set power threshold, it indicates that the parking power consumption during this period may be significant. After the electric vehicle is started and driven for a period of time, its SOC is highly likely to fluctuate. Therefore, a reminder message for SOC correction is sent to the user terminal associated with the electric vehicle's identification information. This prompts the vehicle owner to correct the vehicle's SOC before starting the vehicle, thereby avoiding range anxiety caused by SOC fluctuations and preventing the electric vehicle from breaking down while driving.

[0023] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail below with specific examples. The following specific examples can be combined with each other, and the same or similar concepts or processes can not be described again in some examples. The embodiments of the present application will be described below with reference to the drawings.

[0024] Please refer to Figure 1 The SOC correction reminding method for an electric vehicle provided in the embodiments of the present application is applied to a cloud server. The method provided in the embodiments of the present application includes S101-S103, wherein, S101: receiving a static parking instruction uploaded by an electric vehicle, the static parking instruction carrying identity information of the electric vehicle.

[0025] Exemplarily, after the electric vehicle is parked and turned off, the electric vehicle can upload a static parking instruction to the cloud server. The identity information of the electric vehicle can be, but is not limited to, a vehicle identification code VIN (Vehicle Identification Number, VIN).

[0026] S102: determining average power consumption of each time of static parking of the electric vehicle in history based on the identity information of the electric vehicle.

[0027] Specifically, the specific implementation of S102 includes, but is not limited to, the following two kinds: The first kind: as shown in Figure 2 The specific implementation of S102 can include S201-S204, wherein, S201: based on the identity information of the electric vehicle, obtaining average static duration, vehicle habit features associated with static power consumption, and basic power consumption per unit time of each time of static parking of the electric vehicle in history.

[0028] The basic power consumption can be the power consumption of the engine anti-theft module, the door sensor, and the battery management module of the vehicle, etc.

[0029] S202: determining additional power consumption per unit time of the electric vehicle according to the vehicle habit features associated with static power consumption.

[0030] For example, the vehicle habit features associated with static power consumption include the proportion of sentinel mode usage times and the proportion of refrigerator usage times. In this way, in the case that the proportion of sentinel mode usage times is greater than a set proportion threshold (such as 80%), the power consumption per unit time of the sentinel mode of the electric vehicle is obtained. In the case that the proportion of refrigerator usage times is greater than a set proportion threshold (such as 80%), the power consumption per unit time of the refrigerator is obtained; and the sum of the power consumption per unit time of the sentinel mode of the electric vehicle and the power consumption per unit time of the refrigerator is determined as the additional power consumption per unit time of the electric vehicle.

[0031] In other implementations, the actual power consumption of the electric vehicle during each historical parking period can be retrieved from a preset database based on the electric vehicle's identity information; and the average power consumption of the electric vehicle during each historical parking period can be determined based on the actual power consumption of the electric vehicle during each historical parking period.

[0032] S203: Combine the base power consumption per unit time with the additional power consumption of the electric vehicle per unit time. The sum of these values ​​is determined as the total power consumption of the electric vehicle per unit time.

[0033] S204: Determine the average power consumption of the electric vehicle during each historical period of stationary parking based on the average stationary parking time of the electric vehicle and the total power consumption of the electric vehicle per unit time.

[0034] For example, according to formula P 平均 =P 总 / t, determines the average power consumption of the electric vehicle during each historical period of stationary parking. Where P 平均 P represents the average power consumption of an electric vehicle during all historical periods of stationary parking, where t is the average parking time. 总 This represents the total power consumption of an electric vehicle per unit of time.

[0035] S103: When the average power consumption is greater than the set power threshold, send a wake-up message for SOC correction to the user terminal associated with the electric vehicle's identity information.

[0036] For example, the set battery threshold can be, but is not limited to, 5% or 10%; the SOC correction reminder message is a prompt instructing the owner to slowly charge the electric vehicle until the remaining battery level is 100%. In this way, the owner can slowly charge the electric vehicle until the remaining battery level is 100%, and during the slow charging process, the electric vehicle will automatically correct its SOC.

[0037] It should be noted that the system can query the frequently used times associated with the electric vehicle's identity information from a preset database; when the current time reaches the frequently used time or the electric vehicle is detected to be charging, a reminder message for SOC correction will be sent to the user terminal associated with the electric vehicle's identity information.

[0038] In summary, the SOC correction reminding method for an electric vehicle provided in the embodiments of the present application can receive a static parking instruction uploaded by an electric vehicle, and the static parking instruction carries identity information of the electric vehicle. Understandably, the electric vehicle will generate a continuous irregular small current discharge that is not easy to be monitored during the static process, and has a certain static power consumption. Then, the average power consumption of the electric vehicle in each static parking in history can be determined based on the identity information of the electric vehicle. Understandably, the average power consumption of the electric vehicle in each static parking in history can represent the power consumption of the electric vehicle in the current static process. In the case where the average power consumption is greater than a set power threshold, it is indicated that the static power consumption of the electric vehicle in the current static process can also be large. After the electric vehicle is started and travels for a period of time, the SOC of the electric vehicle is most likely to jump. Therefore, the reminding information of performing SOC correction is sent to the user terminal associated with the identity information of the electric vehicle. In this way, the vehicle owner can be prompted to correct the SOC of the vehicle before the vehicle is started, so as to avoid the range anxiety caused by the jump of the SOC and avoid the situation that the electric vehicle breaks down during driving.

[0039] In addition, the method provided in the embodiments of the present application can further include: Step 1: In the case where the average power consumption is greater than a set power threshold, the identity information of the electric vehicle is marked.

[0040] Step 2: Receive an SOC abnormality query instruction from a customer service terminal, wherein the SOC abnormality query instruction carries owner identity information. Step 3: If the identity information of the electric vehicle associated with the owner identity information is marked, the identity information of the marked electric vehicle is sent to the customer service terminal.

[0041] Based on the above steps 1-3, when the owner comes to the customer service center store, the customer service personnel can query the identity information of the electric vehicle associated with the owner identity information according to the owner identity information. If the marked identity information of the electric vehicle is queried in the customer service terminal, the maintenance personnel can be notified to check the electric vehicle of the owner and give the SOC correction suggestion after checking the electric vehicle.
