Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
An electric vehicle, a charging control method and apparatus thereof, a terminal device, and a storage medium according to embodiments of the present invention are described below with reference to the accompanying drawings.
Fig. 1 is a flowchart of a charging control method for an electric vehicle according to an embodiment of the present invention. The charging control method can be realized through terminal equipment bound with the electric automobile, wherein the terminal equipment can be a vehicle-mounted terminal or a mobile terminal.
As shown in fig. 1, the charging control method of the electric vehicle includes the steps of:
s11, a charging parameter setting instruction input for the target full charge time is received.
Specifically, when the electric automobile is charged, different charging parameters and corresponding full charge time can be displayed through a display screen of the terminal device, and then the automobile owner can compare the parking time with the full charge time and select the charging parameter corresponding to the full charge time closest to the parking time so as to input a charging parameter setting instruction. The full charge time closest to the stop time is defined as the target full charge time.
And S12, determining the charging demand current according to the setting instruction.
In this embodiment, the charging parameter may be a charging current or a charging power. If the set charging parameter is determined to be the charging current according to the setting instruction, determining that the charging required current is the charging current; if the set charging parameter is determined to be charging power according to the setting instruction, acquiring the current voltage of a power battery of the electric automobile, and calculating to obtain the charging required current according to the current voltage and the charging power, wherein the calculation formula is as follows: the charging demand current is the charging power/present voltage.
S13, the charging demand current is sent to the charging pile, so that the charging pile charges the electric automobile according to the charging demand current.
Specifically, a charging controller of the electric vehicle, such as a BMS (Battery Management System), sends a charging demand current to the charging pile through a message (such as a BCL message, i.e., a Battery charging demand message), and after the charging pile acquires the message containing the charging demand current, the electric vehicle can be charged according to the charging demand current. Therefore, the charging parameters are set according to the charging time, more charging requirements of the car owners can be met, the service life of the power battery of the electric car can be prolonged to a certain extent, and the worry of part of car owners about the service life of the power battery is reduced.
In an embodiment of the present invention, before the step of receiving the charging parameter setting instruction input for the target full charge time, as shown in fig. 2, the charging control method of the electric vehicle may further include:
and S21, receiving a charging parameter selection function starting instruction.
And S22, controlling the electric automobile to start the charging parameter selection function according to the starting instruction, and sending first prompt information to prompt various charging parameters and corresponding full charging time.
Specifically, a key corresponding to the charging parameter selection function may be displayed on an operation interface of the terminal device, and if the user triggers the key before charging starts to control the electric vehicle to start the charging parameter selection function, the terminal device may send a first prompt message after receiving a charging parameter selection function start instruction, for example, display a plurality of charging parameters and corresponding full charging time on a display screen of the charging device, so that the user may select corresponding charging parameters according to the full charging time. Accordingly, if the user does not activate the button before charging begins, the electric vehicle may be charged in a default charging mode, such as charging at a default fast charge demand current.
As an example, the first prompt message may also be sent in a form of voice broadcast, and the user may input the charging parameter selection function starting instruction through voice.
As an example, after the electric vehicle starts the charging parameter selection function, the terminal device may pop up a charging parameter setting interface, and a user may directly input a target full charge time through the interface, match a corresponding charging parameter according to the target full charge time, and then directly input a setting instruction according to the matched charging parameter.
In an embodiment of the present invention, after the step of receiving the charging parameter setting instruction input for the target full charge time, as shown in fig. 3, the charging control method of the electric vehicle may further include:
and S31, receiving a charging parameter storage instruction.
And S32, storing the current charging parameters and the current charging scene according to the storage instruction, wherein the current charging scene comprises a charging station where the electric automobile is located currently.
Specifically, a storage key can be further arranged on an operation interface of the terminal device, after the charging parameters are set by a user, if the storage key is triggered, the terminal device can store the currently set charging parameters and the currently set charging scene, and establish a corresponding relationship between the charging parameters and the charging stations in the currently set charging scene, so that the corresponding charging parameters can be popped up by default for the user to select when the charging stations are charged next time, and the user operation is facilitated. The charging parameters and the corresponding relation can be stored in a storage unit of the terminal device, and can also be transmitted to the cloud server by the terminal device for storage.
As an example, the charging scenario may further include a state of charge of the power battery when the charging parameter is set and a full charging time corresponding to the set charging parameter, so that the charging parameter may be set more accurately when charging next time.
In an embodiment of the present invention, after the charging parameters are set, the terminal device may also automatically store the currently set charging parameters and the current charging scenario, and establish a corresponding relationship between the charging parameters and the current charging scenario.
As one example, the automatic storage operation may be performed when the frequency of occurrence of the current charging scenario is high. For example, if the frequency of charging at the current charging station is greater than a preset threshold, the set charging parameters and the corresponding relationship between the charging parameters and the charging scene are automatically stored. Therefore, the accuracy of the recommendation of the charging parameters can be improved.
In an embodiment of the present invention, after the step of controlling the electric vehicle to start the charging parameter selection function according to the start instruction, as shown in fig. 4, the charging control method of the electric vehicle may further include:
and S41, acquiring the current charging scene, and judging whether the corresponding charging parameters are stored in the current charging scene.
And S42, if the corresponding charging parameters are stored in the current charging scene, sending out second prompt information to prompt the stored charging parameters.
Specifically, after the electric vehicle starts the charging parameter selection function, if there is a storage of the corresponding charging parameter in the current charging scenario, the terminal device may send a second prompt message, for example, display the corresponding charging electrical parameter and the full charging time on the display screen, so that the user may determine whether to charge the electric vehicle with the charging parameter. If the charging parameters are determined to be correct, a confirmation instruction can be input through the terminal equipment, the charging parameters are sent to the BMS of the electric automobile, and then the BMS can send the charging parameters to the charging pile. If not, a denial instruction can be input through the terminal equipment, and then the terminal equipment can send out the first prompt information so as to facilitate the selection of a user.
In an embodiment of the present invention, if the step of controlling the electric vehicle to start the charging parameter selection function occurs after the charging is started, the step of determining whether the corresponding charging parameter is stored in the current charging scene may not be performed, and the first prompt message may be directly issued. Therefore, wrong recommendation can be avoided to a certain extent, and the timeliness of charging control is improved.
In an embodiment of the present invention, after the step of sending the second prompt message, as shown in fig. 5, the charging control method of the electric vehicle may further include:
s51, a change instruction for the stored charging parameter is received.
And S52, sending out a third prompt message according to the change instruction so as to prompt various charging parameters and corresponding full charging time.
Specifically, if the charging parameter included in the second prompt information does not meet the user requirement, the user may input a change instruction through the terminal device, for example, in an inquiry frame of the second prompt information (e.g., whether to select the charging parameter for charging), the no option is selected to trigger the input of the change instruction. The terminal device may send out a third prompt message according to the change instruction, where the third prompt message may be the same as the charging parameter included in the first prompt message, or may be a message formed by removing the charging parameter in the second prompt message from the first prompt message. Therefore, the charging parameters meeting the requirements can be conveniently selected by the user.
As an example, when the set charging parameter is larger than the power/current limit value of the power battery limited by other factors such as the environment, the BMS may take the parameter limit value of the required current value in the BCL message sent by the charging pile. For example, when the maximum temperature of the power battery is T1 ℃, the maximum current allowed by the power battery is I61, but the set charging current I62, I62 > I61, and at this time, the charging demand current in the BCL message sent by the BMS to the dc charging pile is I61.
In summary, according to the charging control method of the electric vehicle in the embodiment of the invention, the charging parameters are selected according to the full charging time, so that more charging requirements of a vehicle owner can be met, and the service life of the power battery of the electric vehicle can be prolonged to a certain extent. In addition, by storing the charging parameters, the operation times of the user can be reduced, and the user experience is improved.
Further, the present invention proposes a computer-readable storage medium.
In an embodiment of the present invention, a computer program is stored on a computer-readable storage medium, and when the computer program is executed by a processor, the method for controlling charging of an electric vehicle is implemented.
The computer readable storage medium of the embodiment of the invention can meet more charging requirements of an owner and can prolong the service life of a power battery of an electric vehicle to a certain extent when the computer program on the computer readable storage medium is executed by the processor.
