While a specific embodiment of a method for replenishing the charge level of a vehicle power battery according to the present application will be described below, fig. 2 is a flowchart of a method for replenishing the charge level of a vehicle power battery according to the embodiment of the present application, and the present specification provides the method operation steps as shown in the embodiment or the flowchart, but may include more or less operation steps based on conventional or non-inventive labor. The order of steps recited in the embodiments is only one of many possible orders of execution and does not represent the only order of execution, and in actual execution, the steps may be performed sequentially or in parallel as in the embodiments or methods shown in the figures (e.g., in the context of parallel processors or multi-threaded processing). As shown in fig. 2, the method includes:
s201: acquiring the current residual capacity of the power battery;
in the embodiment of the application, the vehicle-mounted controller can monitor the State of Charge (SOC) of the power battery in real time, so as to determine the remaining capacity of the power battery, and can also obtain the current remaining capacity of the power battery by receiving a battery feedback signal. Optionally, the onboard controller is an Electronic Control Unit (ECU).
S203: if the current residual electric quantity is less than or equal to a first threshold value, current running information of the vehicle is obtained;
in the embodiment of the application, the vehicle-mounted controller compares the acquired current residual electric quantity of the power battery with a first threshold value to judge whether the electric quantity of the power battery needs to be supplemented with the electric quantity, and if so, the current running information of the vehicle is acquired; if not, the vehicle normally runs without considering the problem of electric quantity supplement of the power battery. Specifically, fig. 3 is a schematic diagram illustrating a change in a state of charge of a power battery according to an embodiment of the present disclosure, as shown in fig. 3, a point O is a full-charge state of the power battery, and as the vehicle travels, the electric quantity of the power battery gradually decreases, when the electric quantity of the power battery is greater than a control point a (cal dataa), the vehicle travels normally under the driving of the power battery, and when the electric quantity of the power battery decreases to the control point a (cal dataa), the electric quantity of the power battery has decreased more, so as to ensure continuous travel of the vehicle, at this time, current travel information of the vehicle is obtained, so as to determine an electric quantity supplement scheme of the power battery.
S205: and recommending an electric quantity supplement scheme of the power battery according to the current running information.
In the embodiment of the application, when the electric quantity of the power battery is reduced to the control point A, a proper electric quantity supplement scheme of the power battery is determined according to the acquired current running information of the vehicle, and recommendation information is sent to a driver. Optionally, the current driving information includes current position information of the vehicle and energy consumption information of the vehicle. The current position information may be obtained by Positioning the current position of the vehicle through a vehicle-mounted navigation device, such as a beidou navigation device, a Global Positioning System (GPS), and the like, to obtain the current position information of the vehicle. The energy consumption information of the vehicle can be obtained by calculating the energy consumption of the vehicle in the current load state within the preset time of the previous period, namely when the residual electric quantity of the power battery is before the point A. The energy consumption information of the vehicle can also be calculated through historical energy consumption. As an example, the energy consumption of the remaining capacity of the power battery in any time interval between the point O and the point A is obtained, and the average energy consumption in the time interval is calculated and can be used as the current energy consumption information. In order to improve the calculation accuracy and avoid calculation errors caused by random single time intervals, the energy consumption of the residual capacity of the power battery in a plurality of arbitrary time intervals between the point O and the point A can be obtained, and then the average energy consumption is calculated. As another example, the current load state of the vehicle is acquired, and then the energy consumption in the time that the remaining capacity of the power battery coincides with the current load state between the point O and the point a is determined as the current energy consumption information. As another example, energy consumption information for a vehicle is determined based on historical energy consumption profiles for the vehicle. The calculated energy consumption in this case is more than that of the difference in energy consumption due to the fact that different drivers have different driving habits. Preferably, the historical energy consumption information calculated according to the historical energy consumption and the current load energy consumption information calculated in the current vehicle state are calculated by setting different weight coefficients to obtain the energy consumption information.

S403: acquiring a power change station within a distance range in which a vehicle can run according to the current position information;
in the embodiment of the application, the distance which can be traveled by the power battery under the current residual capacity is obtained through calculation, then the current position of the vehicle is taken as the center, the distance which can be traveled by the vehicle driven by the current residual capacity is taken as the radius, and the power change station in the area range is obtained. In some embodiments, the current position of the vehicle can be used as a center, the distance that the vehicle can run driven by the current residual capacity is used as a radius, and the charging stations and the charging piles within the area range are obtained, so that more choices for supplementing the battery capacity can be provided for the driver. In some embodiments, after the distance that the power battery can travel under the current remaining capacity is calculated, all reachable power changing stations may not be acquired, but the power changing station closest to the current position of the vehicle is directly acquired, and information of the power changing station is directly recommended to the driver.
S405: and recommending the power changing station meeting the preset conditions to replace the fully charged power battery for the vehicle.
In the embodiment of the application, the battery replacement stations within the distance range in which the vehicle can run are obtained, one or more battery replacement stations may exist within the range, and if only one battery replacement station exists, information of the battery replacement station is recommended to a driver; if a plurality of battery replacement stations exist in the range, one to a plurality of battery replacement stations suitable for replacing the power battery of the vehicle are recommended to the driver through a certain selection strategy.
