Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some, but not all embodiments of the present invention. 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 invention.
The terms "comprising" and "having," and any variations thereof, as referred to in embodiments of the present invention, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements but may alternatively include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
As shown in fig. 1, an execution process of the method for controlling charging of an electric vehicle according to the embodiment of the present invention may include the following steps:
101. vehicle information is acquired.
Wherein the vehicle information includes vehicle battery data.
102. And determining the target electric quantity according to the vehicle information and the preset charging termination condition.
The target electric quantity is the electric quantity of the vehicle battery which stops charging, and the target electric quantity is smaller than the rated electric quantity of the vehicle battery;
103. when it is determined that the real-time capacity of the vehicle battery reaches the target capacity, the charging operation is terminated.
In the above step, when the vehicle is charged, vehicle information including battery data may first need to be acquired, where the battery data may include information such as a brand and parameters corresponding to the battery. In this embodiment, the mode of acquiring the vehicle information may be acquired through the charging pile, and when the vehicle is connected to the charging pile, a detection program built in the charging pile acquires the vehicle information required by this embodiment from the vehicle. Of course, in practical applications, the method is not limited to the above-mentioned method, for example, after the vehicle is connected to the charging pile, the vehicle information request information is sent to the vehicle-mounted terminal, and after the vehicle-mounted terminal is displayed to the user, the user performs input, so that the vehicle information is acquired from the user input information. Here, the manner of acquiring the vehicle information is not limited, and may be acquired based on actual needs of the user.
After the vehicle information is acquired, the target amount of electricity for terminating the charging of the battery may be determined based on the vehicle information and a preset termination condition. The preset charging termination condition may include determination conditions corresponding to various different parameter information, for example, when the vehicle information includes brand information, the preset charging termination condition may be a charging termination determination condition of a corresponding brand. Therefore, the preset charging termination condition is determined based on the specific information parameter type included in the vehicle information when step 102 is executed, and when the vehicle information includes a plurality of different parameter information, the preset charging termination condition corresponds to a plurality of different parameter information.
After step 102, the target electric quantity for terminating charging of the battery when the current vehicle is charged can be determined, so that in the subsequent charging process, whether the real-time electric quantity reaches the target electric quantity or not can be determined, and when the target electric quantity is reached, the charging operation is terminated. Specifically, the charging operation can be terminated by controlling the charging pile to stop charging. Because the target electric quantity is smaller than the rated electric quantity of the vehicle battery, the charging operation can be stopped after the target electric quantity is charged, the problem of overcharge which can be stored when the battery reaches the maximum SOC is avoided, and the safety risk of the vehicle battery during charging is reduced.
In a possible embodiment, the brand, the specific setting of the vehicle, and the setting of the charging pile may be selected according to the judgment basis for terminating the charging operation, and therefore, the preset charging termination condition includes: brand setting conditions, vehicle setting conditions, and charging pile setting conditions. The brand setting condition may include a vehicle brand and a battery brand, among others.
Based on different predetermined charging termination conditions, the step 102 is adjusted accordingly when executed.
Based on this, in one possible embodiment, when the preset termination charging condition is the brand setting condition, the target electric quantity includes a first electric quantity parameter;
the determining the target electric quantity according to the vehicle information and the preset charging termination condition in step 102 may include:
firstly, determining a target brand of the vehicle according to the vehicle information;
then, according to the target brand, determining corresponding electric quantity from the brand setting condition as the first electric quantity parameter. Wherein the first charge parameter is a vehicle stop charging charge determined according to a brand to which the vehicle belongs.
Therefore, when the preset charging termination condition is the brand setting condition, the first electric quantity parameters corresponding to different brands can be used as the target electric quantity, so that the condition that the current vehicle charges the vehicle battery can meet the requirement that different brands select the appropriate target electric quantity, the accuracy of electric quantity control in the charging process is guaranteed, and the safety of the vehicle battery during charging is further guaranteed.
In a possible implementation manner, when the preset charging termination condition is the vehicle setting condition, the vehicle information includes the vehicle setting condition, and the target electric quantity includes a second electric quantity parameter;
in the step 102, the determining the target electric quantity according to the vehicle information and the preset charging termination condition may include:
firstly, acquiring vehicle setting conditions from the vehicle information;
then, the second electric quantity parameter is determined according to the vehicle setting condition, and the second electric quantity parameter is the electric quantity for stopping charging of the vehicle, which is preset based on a preset control terminal.
In this example, the vehicle setting condition may be understood as a condition for terminating the power failure operation, which is preset by the user, so that in this embodiment, the second power parameter can be determined as the target power based on the vehicle setting condition preset by the user, and thus, the power corresponding to the termination of the charging operation during charging can be manually set based on the vehicle owner, thereby ensuring that the charging process does not avoid the safety problem caused by overcharging, and meeting different needs of the user for adjustment, thereby having better flexibility.
It should be noted that, in this embodiment, the setting condition may be set in advance through a vehicle-mounted terminal of the vehicle, and when a battery of a subsequent vehicle is charged, the vehicle is acquired by the charging pile after being connected to the charging pile. Certainly, in practical application, the setting can be performed based on corresponding programs or software through intelligent terminals such as mobile phones, and the setting is sent to the charging pile after the charging pile is connected with the vehicle battery.
In a possible implementation manner, when the preset charging termination condition is the charging pile setting condition, the target electric quantity comprises a third electric quantity parameter;
in the step 102, the target electric quantity is determined according to the vehicle information and the preset charging termination condition, and the executing may specifically include:
firstly, determining a vehicle identifier according to the vehicle information;
and then, determining corresponding electric quantity from the charging pile setting conditions according to the vehicle identification to serve as the third electric quantity parameter.
In the above step, the application scenario may be that the charging pile sets a corresponding vehicle identifier for the vehicle before charging, and sets a charging electric quantity corresponding to each vehicle, that is, a third electric quantity parameter, as the target electric quantity in the charging pile in advance according to the vehicle identifier, and when the vehicle is connected to the charging pile, the charging is performed according to the set third electric quantity parameter.
Therefore, when the preset condition of stopping charging is the charging pile setting condition, the corresponding third charging capacity is determined as the target capacity according to the vehicle identification, the charging control can be carried out by the setting of the charging pile in the charging process, the safety problem caused by over-charging can be avoided during charging, the target capacity can be adjusted and controlled based on the charging pile, and the effect of flexibly adjusting the charging capacity is achieved.
In a possible embodiment, since the preset charging termination condition may not be unique, the target electric quantity may also not be unique, and therefore, the target electric quantity at least includes one electric quantity parameter;
thus, before terminating the charging operation when the real-time charge amount of the vehicle battery is determined to reach the target charge amount in the aforementioned step 103, the aforementioned steps may be performed to further include:
and judging whether the electric quantity parameter contained in the target electric quantity is unique.
Based on this, when the real-time electric quantity of the vehicle battery is determined to reach the target electric quantity in the foregoing step 103, when the charging operation is terminated, the method may specifically include:
if the electric quantity parameter contained in the target electric quantity is not unique, determining the execution electric quantity in the plurality of electric quantity parameters according to a preset rule;
terminating the charging operation when it is determined that the real-time electric quantity of the vehicle battery reaches the execution electric quantity.
Therefore, the target electric quantity obtained in the step can be a plurality of electric quantity parameters, and the method can ensure that when the electric quantity parameters are not unique, one of the electric quantity parameters is selected as the execution electric quantity according to the preset rule and is used as the basis for the subsequent electric quantity termination operation, so that the interference caused by the plurality of electric quantity parameters is avoided, and the safety of the charging process of the vehicle battery is ensured.
In a possible implementation manner, the preset rule in the foregoing embodiment determines the execution manner of the power amount differently due to different requirements and settings of users, and thus the preset rule may be an extreme value rule or a priority rule. The extreme value rule is used for determining the minimum electric quantity parameter from a plurality of electric quantity parameters, and the priority rule is used for determining the electric quantity parameter with the highest priority from the plurality of electric quantity parameters. In other words, in the process of determining the execution electric quantity, the minimum electric quantity parameter may be selected as the execution electric quantity in the manner of an extreme value rule, and the electric quantity parameter with the highest priority may be determined as the execution electric quantity from among the plurality of electric quantity parameters in the target electric quantity in the manner of a priority rule according to the priority.
Based on this, the determining, according to a preset rule, the execution electric quantity in the plurality of electric quantity parameters in the foregoing example may specifically include:
and when the preset rule is an extreme value rule, determining the minimum electric quantity parameter from the plurality of electric quantity parameters as the execution electric quantity. For example, for convenience of description, the electric quantity according to the present embodiment may be determined according to the SOC load electric quantity, and therefore, when the first electric quantity parameter is 0.9, the second electric quantity parameter is 0.8, and the third electric quantity parameter is 0.85,
and when the preset rule is a priority rule, selecting the electric quantity parameter with the highest priority from the plurality of electric quantity parameters as the execution electric quantity.
It should be noted that, when the execution electric quantity is determined according to the priority rule, actually, each electric quantity parameter may add a corresponding priority level according to a preset priority relationship in the determination process, for example, when the first electric quantity parameter is a first level, the second electric quantity parameter is a second level, and the second level is higher than the first level, the second electric quantity parameter may be determined as the execution electric quantity.
