All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
First embodiment
Referring to fig. 1, a schematic flow chart of a method for charging an electric vehicle according to this embodiment is shown, where the method includes the following steps:
s101: and calculating the power consumption of the target vehicle in a first preset time range in the future according to the running data of the target vehicle.
In this embodiment, any electric vehicle that is charged by this embodiment is defined as a target vehicle, and this embodiment does not limit the battery type of the battery on board the target vehicle, and may be, for example, a lithium ion battery, a nickel metal hydride battery, or the like.
In order to reduce the number of times of charging the vehicle-mounted battery of the target vehicle and improve the service life of the vehicle-mounted battery, firstly, the running data of the target vehicle needs to be acquired, and then, the data processing is performed on the running data to estimate the power consumption of the target vehicle within a future time range.
The running data of the target vehicle refers to the running parameters and the environment parameters of the target vehicle during historical running, the running parameters and the environment parameters during running in a future period of time, and the like.
Specifically, in one possible implementation manner of the embodiment, the running data of the target vehicle may include a historical power consumption amount of the target vehicle, and the specific implementation process of the step S101 "calculating the power consumption amount of the target vehicle in the future first preset time range according to the running data of the target vehicle" may include the following steps a1-a 2:
step A1: and acquiring the historical power consumption of the target vehicle in a second preset time range from the historical discharge record of the target vehicle.
In this implementation manner, in order to calculate the power consumption of the target vehicle in the future within the first preset time range, the power consumption of the target vehicle in the past time range may be first obtained from the historical discharge record of the target vehicle, where the past time range is defined as the second preset time range, it should be noted that a specific value of the second preset time range may be set according to an actual situation and a value of the first preset time range, which is not limited in this application, and may be set to 30 days and the like, for example. After the historical power consumption amount of the target vehicle in the second preset time range is obtained, the subsequent step a2 may be further continued.
Step A2: and calculating the power consumption of the target vehicle in a future first preset time range according to the historical power consumption of the target vehicle in a second preset time range.
In this implementation manner, after the historical power consumption amount of the target vehicle in the second preset time range is obtained from the historical discharge record of the target vehicle through step a1, data processing may be further performed on the historical power consumption amount, so as to estimate the power consumption amount of the target vehicle in the future first preset time range according to the processing result.
For example, the following steps are carried out: assuming that the first preset time range is two days, the second preset time range is 30 days, and the electric quantity consumed by the target vehicle in the past 30 days is 90 kilowatts obtained from the discharge records of the target vehicle, the electric consumption of the target vehicle per day can be calculated to be 3 kilowatts hours, that is, 90/30 kilowatt hours, according to the historical electric consumption, and thus, the possible electric consumption of the target vehicle in the future two days can be estimated to be 6 kilowatts hours, that is, 3 × 2 kilowatt hours.
In a possible implementation manner of this embodiment, the traveling data of the target vehicle may include the traveled mileage of the target vehicle in the first preset time range in the future and the information of the area where the traveling process is located, and a specific implementation process of the step S101 "calculating the power consumption of the target vehicle in the first preset time range in the future according to the traveling data of the target vehicle" may include the following steps B1-B2:
step B1: and acquiring the driving mileage of the target vehicle in a first preset time range in the future and the information of the area where the driving process is located.
In this implementation manner, in order to calculate the power consumption of the target vehicle in the first preset time range in the future, the driving mileage of the target vehicle in the first preset time range in the future, the information of the area where the driving process is located, and the like may be obtained first.
Specifically, the distance (or mileage) of the target vehicle in the first preset time range in the future may be acquired by using an existing or future distance acquisition method, for example, the mileage of the target vehicle in the first preset time range in the future may be estimated by means of an electronic map. For example, assuming that the user to which the target vehicle belongs plans to drive the target vehicle from beijing to tianjin, the driving mileage from beijing to tianjin can be queried to be about 130 km by using the electronic map.
Further, the information of the area where the target vehicle runs within the first preset time range in the future can be acquired, where the information of the area where the target vehicle runs within the first preset time range in the future refers to information of weather (such as sunny days, rainy days, and the like), temperature, road conditions, and the like of each area where the target vehicle runs within the first preset time range in the future. For example, the weather information of the area where the target vehicle is traveling in the first preset time range in the future may be acquired by using an existing or future weather acquisition method. For example, if a user of the target vehicle plans to drive the target vehicle from beijing to harlbine, the weather conditions of the areas such as north river, liaoning, jilin, and black longjiang in the first preset time range in the future can be inquired through the weather information inquiry software installed on the inquiry mobile phone, that is, the weather information of each area through which the target vehicle passes in the driving process in the first preset time range in the future is inquired. After the information of the driving distance of the target vehicle within the first preset time range in the future, the weather, the temperature of the area where the driving process is located, the road construction condition and the like is obtained, the subsequent step B2 may be further performed continuously.
Step B2: and estimating the power consumption of the target vehicle in the first preset time range in the future according to the driving mileage of the target vehicle in the first preset time range in the future and the information of the area where the driving process is located.
In this implementation manner, after the driving distance of the target vehicle in the first preset time range in the future and the information of the area where the driving process is located are obtained through step B1, the power consumption of the target vehicle in the first preset time range in the future can be estimated further by combining the driving distance and the information of the area where the driving process is located.
For example, the following steps are carried out: assuming that the first preset time range is two days and the user of the target vehicle plans to drive the target vehicle to make one round trip between beijing and tianjin within the first preset time range in the future (i.e. within two days), after the driving mileage from beijing to tianjin is about 130 km by using the electronic map, the driving mileage of the user of the target vehicle driving the target vehicle within the two days in the future can be estimated to be about 260 km, and assuming that the power consumption of the vehicle-mounted battery of the target vehicle is about 0.17 kwh per km, the power consumption of the target vehicle within the two days in the future can be estimated according to the estimated driving mileage, namely 0.17 × 260 kwh is about 44.2 kwh.
Meanwhile, when calculating the power consumption of the target vehicle in the first preset time range in the future, information of a region where the target vehicle runs in the first preset time range in the future needs to be considered, taking temperature information as an example, it can be understood that the influence on the power consumption of the target vehicle may be different due to different temperatures, for example, when the temperature is too high or too low, an air conditioner in the target vehicle needs to be turned on to cool or warm, and these situations will increase the power consumption of the target vehicle.
In a possible implementation manner of this embodiment, the travel information of the user to which the target vehicle belongs within the first future preset time range may also be obtained, and then the step S101 of calculating the power consumption of the target vehicle within the first future preset time range according to the driving data of the target vehicle may specifically include: and calculating the power consumption of the target vehicle in a first future preset time range according to the travel information of the user.
In this implementation manner, after obtaining the travel information of the user to which the target vehicle belongs within the first future preset time range, the power consumption of the target vehicle within the first future preset time range may be further calculated according to the travel information, for example, after obtaining the lodging information ordered by the user to which the target vehicle belongs on other software, if information such as a train ticket, an air ticket, and the like ordered by the user is not queried at the same time, the travel mode corresponding to the travel of the user may be estimated as driving the target vehicle, and the power consumption of the target vehicle within the first future preset time range may be further calculated by using the above steps a1-a2 and/or B1-B2.
For example, the following steps are carried out: assuming that the location of the target vehicle is beijing, and the accommodation information of a certain hotel in shenyang after the user of the target vehicle reserves two days by other software is acquired, and meanwhile, the user is not inquired about that the user orders train tickets, air tickets and other information in the last two days, it can be estimated that the travel mode adopted by the user in the journey may be the driving target vehicle, and further, the power consumption of the target vehicle (namely, the power consumption of the driving target vehicle from beijing to shenyang) in the next two days can be calculated by using the modes of the steps A1-A2 and/or B1-B2 and the like.
S102: and judging whether the residual capacity of the vehicle-mounted battery of the target vehicle is smaller than the power consumption of the target vehicle in a first preset time range in the future.
In this embodiment, after the power consumption of the target vehicle in the first preset time range in the future is calculated in step S101, it may be further determined whether the current remaining power of the on-board battery of the target vehicle is less than the calculated power consumption of the target vehicle in the first preset time range in the future, if so, the subsequent step S103 is executed, and if not, the subsequent step S104 is executed.
S103: and if the residual electric quantity of the vehicle-mounted battery of the target vehicle is judged to be smaller than the electric consumption quantity of the target vehicle within a first preset time range in the future, the target vehicle is charged after the charging gun is inserted into a charging gun socket of the target vehicle.
In this embodiment, if it is determined in step S102 that the remaining capacity of the battery mounted on the target vehicle is less than the power consumption of the target vehicle within the first preset time range in the future, it indicates that the target vehicle needs to be charged, and the charging may be started after the charging gun is inserted into the charging gun socket of the target vehicle.
S104: and if the residual electric quantity of the vehicle-mounted battery of the target vehicle is judged to be not less than the electric consumption quantity of the target vehicle within the future first preset time range, the target vehicle is not charged.
In this embodiment, if it is determined through step S102 that the remaining capacity of the battery onboard the target vehicle is not less than the power consumption of the target vehicle within the first preset time range in the future, it indicates that the current remaining capacity of the battery onboard the target vehicle is sufficient to support the consumption of the target vehicle within the first preset time range, and therefore, it is not necessary to charge the battery onboard the target vehicle, and thus unnecessary charging of the battery onboard the target vehicle can be reduced, that is, the number of charging times of the battery onboard the target vehicle is reduced, and the service life of the battery onboard the target vehicle is prolonged.
It should be noted that, in a possible implementation manner of this embodiment, it may also be determined whether the target vehicle-mounted battery needs to be charged according to a charging habit of the user, for example, if the charging habit of the user is that the battery needs to be charged in a fixed time period every day regardless of whether the battery is sufficient, even if it is determined through step S102 that the remaining power of the target vehicle-mounted battery is not less than the power consumption of the target vehicle in the first preset time range in the future, the target vehicle-mounted battery still needs to be charged.
In addition, in a possible implementation manner of the embodiment, after the step S102 determines that the remaining capacity of the battery on board the target vehicle is smaller than the power consumption of the target vehicle within the future first preset time range, the embodiment further includes: and sending charging prompt information, wherein the prompt information comprises voice form information and/or short message form information.
In this implementation manner, after it is determined through step S102 that the remaining power of the battery mounted on the target vehicle is less than the power consumption of the target vehicle within the first preset time range in the future, a charging prompt message may be sent to the user to whom the target vehicle belongs, so as to prompt the user to charge the target vehicle as soon as possible and to prompt the user of the power required to be charged. The charging prompt message may include a voice form message and/or a short message form message. For example, people in the vehicle can be reminded in the form of characters and/or pictures on a display screen in a cab of the target vehicle, the current residual capacity of a vehicle-mounted battery of the target vehicle is less than the power consumption of the target vehicle within a first preset time range in the future, and the target vehicle needs to be charged so as to ensure a driving journey within the first preset time range in the future; or, the information such as the specific electric quantity and the like required to charge the vehicle-mounted battery of the target vehicle can be sent to the user in a short message form; or, push information such as the specific electric quantity to be charged and the charging requirement of the vehicle-mounted battery of the target vehicle can be pushed to the user terminal in a software push message mode.
In summary, in the method for charging an electric vehicle provided in this embodiment, first, according to the driving data of the target vehicle, the power consumption of the target vehicle in a first preset time range in the future is calculated, and then, by comparing the remaining power of the battery mounted on the target vehicle with the calculated power consumption of the target vehicle in the first preset time range in the future, it is determined whether to charge the target vehicle. Compared with the current mode of charging the vehicle-mounted battery of the target vehicle at will without considering the charging times, the method and the device fully consider the influence of the charging times on the vehicle-mounted battery, and charge the vehicle-mounted battery under the condition that the power consumption of the target vehicle in a future period of time is judged to exceed the residual capacity of the vehicle-mounted battery, so that the charging times of the vehicle-mounted battery of the target vehicle can be reduced as much as possible, and the service life of the vehicle-mounted battery is prolonged.
