Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. 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.
As described in the background of the invention, in the prior art, the same charging mode is generally adopted for the battery system of the same electric vehicle, however, as the driving range of the electric vehicle increases and the corresponding charging facilities are more and more perfect, the charging and using requirements of the electric vehicle cannot be met by the single charging mode.
In order to solve the above problems, the embodiment of the present application provides a charging method for an electric vehicle, so that a user can flexibly select a charging mode according to actual needs to better use a vehicle.
The embodiments of the present application will be described in detail below with reference to the accompanying drawings.
Example one
Fig. 1 is a flowchart illustrating a charging method of an electric vehicle according to an exemplary embodiment, and referring to fig. 1, the method includes the steps of:
s1: when the charging mode determined by the user is the user-defined charging mode, acquiring a preset charging parameter, and calculating and determining a target charging sub-mode according to the preset charging parameter and a preset calculation rule.
Specifically, in the embodiment of the invention, at least one general charging mode is preset, and different charging modes can be configured for different charging requirements of the vehicle to be charged, namely, the charging mode can be customized. During specific implementation, a user can determine whether to select a general charging mode to charge the vehicle to be charged or to define the charging mode according to the actual use requirement of the vehicle to be charged. As a preferred embodiment, when the user does not select the general charging mode, it indicates that the user needs the customized charging mode. Wherein, when the user selects the general charging mode, the present procedure is ended.
It should be noted that, in the implementation of the present invention, the general charging mode is only a name, and means a default charging mode, which may be a charging mode preset by an electric vehicle manufacturer, or a charging mode set in an electric vehicle by a user, and is not limited herein. The general charging mode may be understood as a standard charging mode, where the standard refers to that a user does not need to input any parameters before charging, and only needs to select a corresponding charging mode. The general charging mode of the present application is not limited to an actual charging rate, a charging depth, and the like, and any charging mode that does not deviate from the inventive concept of the present application can be used as the general charging mode of the present application. In addition, it should be noted that a plurality of general charging modes may be provided in the embodiment of the present invention, that is, the number of the general charging modes is not specifically limited.
Specifically, in the embodiment of the present invention, before selecting to use the general charging mode or selecting the user-defined charging mode, the user may determine whether the vehicle to be charged needs to be charged according to the expected power consumption and the current remaining power of the battery. When the method is specifically implemented, the predicted power consumption is compared with the current residual capacity of the battery, and when the predicted power consumption is larger than the current residual capacity of the battery, the current capacity of the vehicle cannot enable the vehicle to run to a destination, so that charging is needed; when the predicted electricity consumption is equal to the current remaining capacity of the battery, although the current electricity quantity of the vehicle can enable the vehicle to run to the destination, the vehicle is in a state that the battery is not electrified after the vehicle runs to the destination, which is also a situation that the battery is not allowed to run in practical application, so that the charging is needed at the moment; when the predicted used amount is smaller than the current remaining amount of the battery, but the difference between the current remaining amount of the battery and the predicted used amount of the battery is equal to or smaller than the preset threshold value, charging is also required in order not to affect the subsequent normal running after the vehicle reaches the destination. Here, the preset threshold may be set automatically by the vehicle, or may be set differently according to different selections by the user. For example, the preset threshold may be set as an electric quantity corresponding to a predetermined distance traveled by the vehicle, or may be set as an electric quantity corresponding to a predetermined factor of the battery capacity of the vehicle, which is not limited herein. And when the predicted power consumption is smaller than the current residual power of the battery and the difference between the current residual power of the battery and the predicted power consumption is larger than a preset threshold, the charging is not needed.
Specifically, as a preferred embodiment, when it is determined that the user needs to define the charging mode by himself/herself, the preset charging parameters may be received through a preset parameter setting interface. In specific implementation, when the user does not select the general charging mode, the user enters a parameter setting interface, and receives the preset charging parameters input by the user through the parameter setting interface. The preset charging parameters include, but are not limited to, road condition information, estimated arrival time, target departure time and other information of the current trip of the vehicle to be charged. The traffic information includes, but is not limited to, a destination of the current trip, a route of the driving path corresponding to the current trip, and traffic information of each road segment in the driving path.
Specifically, in the embodiment of the present application, the method further includes verifying the received preset charging parameter input by the user. Verifying the preset charging parameter includes, but is not limited to, verifying the reasonableness of the preset charging parameter input by the user. During specific verification, a verification rule can be configured in advance, and after the preset charging parameters input by a user, the rationality of the preset charging parameters is automatically verified by using the verification rule.
Specifically, in the embodiment of the present invention, a plurality of preset charging modes may be preset. After the preset charging parameters are calculated by using the preset calculation rules to obtain the calculation results, the most appropriate target charging sub-mode is matched from the plurality of preset charging modes according to the calculation results. As a preferred example, when the parameters are matched specifically, the preset charging mode with the parameters closest to the calculation result may be determined as the target charging sub-mode. The charging modes at least comprise quick charging and slow charging so as to meet the problems that the predicted arrival time and the required arrival time interval are too close, the charging time is too short and the like. The fast charge and the slow charge are merely descriptions of the charge rate, which do not constitute a limitation on the protection range of the charge rate, but merely illustrate that there are at least two different charge rate charge modes in addition to the general charge mode. Specifically, the target charging sub-mode at least includes parameters such as a charging depth, a charging rate, and a charging time. The charging depth refers to the ratio of the amount of electricity received by the storage battery from an external circuit during charging to the capacity of the storage battery in a fully charged state.

Specifically, in the embodiment of the application, when the current battery remaining capacity of the vehicle to be charged can complete the current travel, the battery can be charged by selecting the smaller first preset current, so that on one hand, the damage to the performance of the battery caused by the use of the overlarge current for charging can be avoided, and on the other hand, the problems that the vehicle to be charged does not have the remaining capacity to support the vehicle to continue to run after reaching the destination, so that the use is inconvenient and the like can be avoided. And when the current residual electric quantity of the battery of the vehicle to be charged can not complete the current travel, selecting a larger second preset current to charge the battery so as to ensure that the vehicle to be charged has sufficient electric quantity to complete the current travel.
Further, the magnitude of the charging current may be determined according to the above manner, and may also be determined according to a charging time that a user may use to charge the vehicle, and if the charging time is short, a second preset current that is larger is selected to charge the battery, and if the charging time is long, a first preset current that is smaller is selected to charge the battery. The arrangement is that the damage to the battery caused by large-current charging is reduced while the vehicle to be charged is ensured to have sufficient electric quantity to travel to the destination.

Specifically, in order to make the minimum electric quantity required by the current trip obtained through calculation more accurate, in the embodiment of the present application, in addition to considering the influence of various road conditions on the electric power consumption of the vehicle, the influence of various external factors on the battery performance is also considered when the minimum electric quantity required by the current trip is calculated. The parameters affecting the battery performance of each segment include, but are not limited to, the external ambient temperature, and the like, and the parameters affecting the battery performance may generally refer to parameters given by a battery manufacturer. In order to ensure driving safety and driving efficiency, the required minimum amount of electricity may be set to be between 120% and 130% of the calculated actual amount of electricity used.
As a preferred implementation manner, in an embodiment of the present invention, the method further includes:
and calculating to obtain the minimum time required for finishing charging according to the required minimum electric quantity, the current battery residual electric quantity and a preset estimation rule.
Specifically, firstly, the required minimum electric quantity is used to subtract the current battery residual electric quantity to obtain the actual charging electric quantity, secondly, the time required by the actual charging electric quantity is estimated according to parameters such as the charging rate in the target charging sub-mode, and finally, the estimated time required by the actual charging electric quantity is combined according to the preset estimation rule to obtain the minimum time required by the charging, such as the estimated time required by the charging preparation and the leaving of the charging equipment, and the like.
