Fig. 2 is a schematic flow chart of a charging control method according to an embodiment of the present invention, where the method may be applied to an interactive device, and the interactive device may be a smart phone, a smart tablet or a similar smart device of a user, or may be a central console of a vehicle, for example, an on-board T-BOX. The interaction device may communicate with a battery management system BMS of the vehicle to thereby acquire a state of a power battery of the vehicle. As shown in fig. 2, the method comprises the steps of:
Step S202, in response to the charging prediction request, charging performance prediction information of the power battery in the vehicle is displayed, wherein the charging performance prediction information is used for describing a correspondence between a future charging state of the power battery and a battery performance parameter of the power battery. In this step, the charging prediction request may be a request sent by a user, and the user may wish to obtain, based on the request, the performance of the power battery, for example, the performance that can be achieved by the power battery in different states of charge (the states of charge may also be referred to as states of charge of the battery, abbreviated as SOC) after charging. Optionally, the charging performance prediction information may further carry a target charging state, where the target charging state may be set by autonomous input of a user, and the user may control the interaction device to display part of the prediction information of the power battery by setting the target charging state, for example, the charging performance prediction information of the battery from the current state of charge to the target charging state, where the target charging state is less than 100%, instead of displaying all the prediction information of the power battery from the current charging state to full charge, so as to screen out redundant information unnecessary for the user, and provide individualized and flexible selection for the user.
Optionally, the charging performance prediction information may further include information of the vehicle power battery in two states of fast charging and slow charging, and the user may make a decision according to the information in the two states to select a charging mode suitable for the user's own needs, for example, the user may select to charge the power battery to a cut-off charging state by fast charging or select to charge the power battery to a cut-off charging state by slow charging.
The performance of the power battery may be quantified using battery performance parameters, which may include, as an alternative embodiment, at least one of the following: charging duration, endurance mileage and support arrival areas; the corresponding relation between the future charge state and the charge duration characterizes the time consumed for charging the power battery from the current state to the future charge state; the corresponding relation between the future charging state and the endurance mileage represents the endurance mileage of the corresponding vehicle when the electric quantity of the power battery is the future charging state; the correspondence between the future state of charge and the support arrival area characterizes an area that the corresponding vehicle can reach from the current position when the electric quantity of the power battery is the future state of charge.
It should be noted that the charging duration characterizes the charging rate of the battery; the endurance mileage represents the mileage number that the battery's SOC can support the vehicle to normally run under normal conditions without considering the specific condition of the road on which the vehicle is running and the extreme state of the power consumption load of the vehicle; the support arrival region is a region where the SOC of the vehicle power battery estimated in consideration of the road condition around the vehicle can support the arrival of the vehicle traveling. For example, if the vehicle is currently located on a road in a mountain area, the road in the area around the vehicle inevitably climbs or descends, and the running power consumption of the vehicle is obviously different under different road conditions, so that the user can more obviously see whether the area which the user wants to reach is within the range which can be supported by a certain SOC of the vehicle power battery by supporting the parameter of the reaching area.
Step S204, receiving a charge cut-off interaction operation input based on the charge performance prediction information, wherein the charge cut-off interaction operation carries the target battery performance parameters. Optionally, the charge stopping interaction operation may be made by a user who controls the vehicle to charge on the charging pile, and the interaction device executing the charge control method receives the charge stopping interaction operation and obtains, from the operation, a target battery performance parameter carried in the operation, where the target battery performance parameter may represent a performance that the user wants to reach of the charged power battery. For example, the target battery performance parameter may be: and the endurance mileage is greater than or equal to 100 km, or the charging duration is less than or equal to 1 hour, which indicates that the user hopes that the charging process of the vehicle meets the charging condition corresponding to the target battery performance parameter.
Step S206, in response to the charge cutoff interaction operation, determining a cutoff charge state corresponding to the target battery performance parameter according to the correspondence relation between the future charge state and the battery performance parameter.
The future state of charge is the state of charge that the power battery may reach by charging, and the off state of charge is the critical point at which the user wishes the vehicle to stop charging after charging the power battery to the off state of charge. The interaction device can determine the corresponding cut-off SOC according to the target battery performance parameters selected by the user, and then the electric quantity of the vehicle power battery is charged to the cut-off SOC, so that the personalized charging requirement of the user can be met.
And step S208, controlling the charging pile to charge the vehicle until the power battery of the vehicle reaches a cut-off charging state.
In the step, charging performance prediction information of the power battery in the vehicle is displayed in response to the charging prediction request, wherein the charging performance prediction information is used for describing a corresponding relation between a future charging state of the power battery and a battery performance parameter of the power battery; receiving a charge cut-off interaction operation input based on charge performance prediction information, wherein the charge cut-off interaction operation carries target battery performance parameters; determining a cutoff state of charge corresponding to the target battery performance parameter according to a correspondence between a future state of charge and the battery performance parameter in response to the charge cutoff interaction operation; the charging pile is controlled to charge the vehicle until the power battery of the vehicle reaches a cut-off charging state, so that the aim of providing personalized vehicle charging service for a user is fulfilled, the technical effect of enriching the charging selection of the user when the user charges the vehicle is achieved, and the technical problem that personalized requirements of the user for charging the vehicle by adopting a fixed charging mode intelligently are solved.

The present optional embodiment provides a form of displaying the performance of the power battery for the user, optionally, a two-dimensional coordinate system may be displayed on the interface of the interactive device, where the horizontal axis represents the future charge state of the power battery, and the vertical axis represents the battery performance parameter of the power battery, such as the charging duration or the endurance mileage. The possible condition of charging the power battery can be clearly and clearly defined by the alternative embodiment, so that the user can conveniently make decisions to make personalized charging requests.
As an alternative embodiment, a charge cutoff interoperation for receiving input based on charge performance prediction information includes the steps of: receiving a first selected operation on a future state of charge-battery performance parameter curve, determining a target point in the future state of charge-battery performance parameter curve, wherein the target point corresponds to a target battery performance parameter in the future state of charge-battery performance parameter curve; the first selected operation is regarded as a charge cut-off interaction operation.
Alternatively, the user may directly click on the curve to generate a target point on the curve, or may draw a trace on the interface displaying the future state of charge-battery performance parameter curve, and determine the intersection of the trace and the future state of charge-battery performance parameter curve as the target point. The alternative embodiment provides an intelligent interaction mode, and improves interaction experience when a user selects the target battery performance parameters.
As an alternative embodiment, in response to a charge prediction request, charge performance prediction information of a power battery in a vehicle is presented, including: in the case that the battery performance parameter comprises a support arrival area, generating a target map according to the digital map data and the support arrival area in response to the charging prediction request, wherein the target map is marked with the current position of the vehicle and the area range of the support arrival area; and displaying a target map, wherein the target map belongs to the charging performance prediction information.
Optionally, the target map may be displayed through an interface of the interaction device, and different color blocks on the map may be used to represent a range where the vehicle can be supported by different SOCs of the power battery of the vehicle to travel, for example, when the current SOC of the power battery is a% and the future SOC is b%, the corresponding support reaching area may be represented by a color block of the first color with the current position of the vehicle as the center; when the future SOC is c% (c > b), the support arrival area corresponding to c% may be represented by the color patch of the second color, and the support arrival area corresponding to c% may be represented by the color patch of the first color. Still alternatively, the support arrival regions corresponding to the vehicles at the respective future SOCs may be identified in the target map with the arrival distance lines similar to the contour lines.
