In order to solve the problem that the determination of the discharge residual time length of a power supply device such as a battery pack is inaccurate, the embodiment of the application provides a method and a device for determining the discharge residual time length, a vehicle and a readable storage medium. The method for determining the remaining discharge time period provided in the embodiment of the present application will be described first.
Fig. 2 is a schematic flow chart of a method for determining a remaining discharge duration according to an embodiment of the present application.
The method for determining the remaining discharge time provided by the embodiment of the application can be applied to a device for determining the remaining discharge time, an electronic device, a vehicle and the like. That is, the discharge remaining period determining method may be executed by a discharge remaining period determining apparatus, an electronic device, a controller of a vehicle, and the like. The embodiment of the application will be described by taking a method for determining the remaining discharge time period performed by a controller of a vehicle as an example.
As shown in fig. 2, the discharge remaining period determining method provided by the embodiment of the present application may include the following S210 to S240.
S210, at least one characteristic point of each target load is acquired, wherein the target load comprises a load connected with a power supply device.

S230, determining the target power of each target load according to the weighting coefficient, the real-time power and the historical average power of the target load.

According to the method for determining the discharge residual duration, at least one characteristic point of each target load is acquired; then, according to all characteristic points of each target load, determining the historical average power of the target load; determining the target power of the target load according to the weighting coefficient, the real-time power and the historical average power of the target load; and then determining the discharge residual duration according to the total target power and the residual capacity of the power supply device. That is, in the embodiment of the present application, the historical average power of the target load is determined through all the feature points of each target load, and then the target power of the target load is determined according to the weighting coefficient, the real-time power and the historical average power of the target load, so that the accuracy of determining the target power of the target load can be improved, and the remaining duration of discharge can be determined according to all the target powers and the remaining energy of the power supply device, so that the accuracy of determining the remaining duration of discharge can be improved.
A specific implementation of each of the above steps is described below.
In S110, the target load may include a load connected to the power supply device, that is, the target load may be a load that the power supply device is able to supply power. The target load may include a temperature regulating device, an electric device, and the like.
The characteristic points may be used to characterize the power of the target load. For example, the characteristic point may be a parameter that has a large influence on the load power.
In some embodiments, in the case where the target load is a temperature adjustment device, that is, in the case where the temperature adjustment device is used, the at least one feature point may include at least one of a set temperature value of the temperature adjustment device, a set air volume value, and an ambient temperature value at which the temperature adjustment device is located. Of course, in other embodiments of the present application, where the target load is a temperature regulating device, the at least one characteristic point may also include other characteristic points capable of characterizing the power of the target load.
Taking an application scenario as an example of a vehicle, the temperature adjusting device may include an air conditioner installed in the vehicle, and the environmental temperature value where the temperature adjusting device is located may be the temperature in the vehicle.
In case the target load comprises an electrical consumer, i.e. in case the electrical consumer is in use, the at least one characteristic point comprises a switching state value of the electrical consumer. For example, the switch state value may be used to characterize the switch state of the powered device. For example, a switch state value of 1 may indicate that the switch state is an on state, and a switch state value of 0 indicates that the switch state is an off state.
Still taking the application scene as an example of a vehicle, the power utilization device may include a light-emitting device such as a turn signal, a headlight, a high beam, a dipped headlight, and the like of the vehicle, and a 220V power utilization device such as a charger.
For example, a plurality of target loads and characteristic parameters corresponding to each target load may be stored in a controller of the vehicle. The feature points may be specific values of the feature parameters. In the case where the target load is a temperature adjustment device, the characteristic parameters may include a set temperature of the temperature adjustment device, a set air volume, and an ambient temperature in which the temperature adjustment device is located. In the case where the target load is an electrical device, the characteristic parameter may include a switching state. The controller of the vehicle can firstly determine the characteristic parameters corresponding to the target load according to the target load, and then determine the corresponding characteristic points according to the characteristic parameters.
Of course, in other embodiments of the present application, the target load may be other devices besides a temperature regulating device and an electric device.
In S220, the controller of the vehicle determines, for each target load, a historical average power of the target load according to all the feature points after acquiring at least one feature point of the target load.
In some embodiments, determining the historical average power of the target load based on all of the feature points may include:
acquiring a plurality of historical powers corresponding to all the characteristic points;
the average of all the historical powers is determined as the historical average power of the target load.
In this embodiment, by acquiring a plurality of historical powers corresponding to all the feature points, an average value of all the historical powers is further determined as the historical average power of the target load, and a basis is provided for determining the target power of the target load from the historical average power subsequently.
Historical data may be included in the controller of the vehicle, which may include historical power for each target load at different characteristic points. Historical power for each target load at different characteristic points can be obtained from the historical data.
In some examples, the historical data may also include remaining energy of the power supply, historical voltage of the high voltage device, historical current of the high voltage device, and the like.
Illustratively, in the case where the target load is an air conditioner, the air conditioner sets a temperature value to a1, the air conditioner sets an air volume value to b1, and an ambient temperature value at which the air conditioner is located is c1. The controller of the vehicle stores therein: in the case where the air conditioner sets a temperature value of a1, the air conditioner sets an air volume value of b1, and the ambient temperature value at which the air conditioner is located is c1, the history power of the air conditioner includes d1, d2, d3, d4, and d5. Then, (d1+d2+d3+d4+d5)/5 is taken as the historical average power of the air conditioner.
In S230, the controller of the vehicle may further determine, for each target load, a target power of the target load according to the weighting coefficient, the real-time power of the target load, and the historical average power after determining the historical average power of the target load according to all the feature points for each target load.
In some embodiments, determining the target power of the target load based on the weighting coefficients, the real-time power of the target load, and the historical average power may include:
determining the product of the historical average power and the weighting coefficient as a first power;
determining the difference between 1 and the weighting coefficient as a first difference;
determining a product of the first difference and the real-time power of the target load as a second power;
the sum of the first power and the second power is determined as a target power of the target load.
In this embodiment, the accuracy of determining the target power of the target load can be improved by determining the product of the historical average power and the weighting coefficient as the first power, then determining the product of the first difference value and the real-time power of the target load as the second power, and then determining the sum of the first power and the second power as the target power of the target load, and further, the accuracy of determining the remaining discharge time period can be improved.
Illustratively, the historical average power Px, weighting coefficientThe following equation is satisfied between the real-time power Py and the target power Pz:and the target power of the target load can be rapidly and accurately determined by bringing the weighting coefficient, the real-time power and the historical average power of the target load into the above.
The real-time power of the target load may be a product of the real-time current and the real-time voltage of the target load. For example, the real-time current and real-time voltage of the target load may be detected by a power supply device management system within the vehicle.
In some embodiments, before determining the target power of the target load according to the weighting coefficient, the real-time power and the historical average power of the target load for each target load, the method may further include:
and determining the weighting coefficient of the target load according to the real-time power change rate of the target load.
In this embodiment, the weighting coefficient of the target load is determined by the real-time power change rate of the target load, that is, the determination of the weighting coefficient considers the power fluctuation of the target load, and further, the target power determined according to the weighting coefficient also considers the power fluctuation of the target load, so that the accuracy of the target power can be improved, and further, the accuracy of the determination of the discharge remaining time can be improved.
The real-time power conversion rate of the target load may be determined according to the following manner: determining the product of the real-time current and the real-time voltage of the target load as the real-time power of the target load; dividing the real-time power of the target load by the target time to obtain the real-time power conversion rate of the target load in the target time.
In some embodiments, determining the weighting factor for the target load based on the real-time power rate of change of the target load comprises:
and determining the ratio of the real-time power change rate of the target load to a preset value as a weighting coefficient of the target load.
In the present embodiment, the weight coefficient of the target load can be quickly and accurately determined by determining the ratio of the real-time power conversion rate of the target load to the preset value as the weight coefficient of the target load.
The preset value may be set according to actual conditions, and is not limited herein.
Illustratively, the real-time power conversion rate of the target load ranges from [0, 100] kw/s, the preset value may be 100kw/s, and in the case that the real-time power conversion rate of the target load is 30kw/s, the weighting coefficient of the target load may be 30/100=0.3; in the case where the real-time power conversion rate of the target load is 50kw/s, the weighting coefficient of the target load may be 50/100=0.5; in the case where the real-time power conversion rate of the target load is 73kw/s, the weighting coefficient of the target load may be 73/100=0.73.
It can be understood that when the power fluctuation of the target load is larger, that is, the real-time power conversion rate of the target load is larger, the weighting coefficient is larger, the target power of the target load is larger, and the historical average power of the target load is referenced more, so that the influence of the large power fluctuation of the target load on the determination of the discharge residual duration is reduced, and the accuracy of the determination of the discharge residual duration can be improved.
In S240, the controller of the vehicle may determine the remaining discharge duration based on the total target power and the remaining energy of the power supply device after determining the target power of the target load based on the weighting coefficient, the real-time power of the target load, and the historical average power for each target load.
One target load corresponds to one target power, and all target powers may include target powers respectively corresponding to target loads connected to the power supply device.
In some embodiments, determining the discharge remaining duration from the total target power and the remaining energy of the power supply device may include:
determining the sum of all the target powers as the target total power;
and determining the ratio of the residual energy of the power supply device to the target total power as the residual discharge duration.
In this embodiment, by determining the sum of all the target powers as the target total power, the discharge remaining duration can be rapidly and accurately determined according to the ratio of the remaining energy of the power supply device to the target total power.
The target total power is the total power consumed by all target loads connected with the power supply device.
The controller of the vehicle may store the remaining energy of the power supply device, and thus, the remaining energy of the power supply device may be directly called from itself.
For example, the target load includes N, N is a positive integer, N target powers corresponding to the N target loads include P1, P2, and P3 … PN, and one target load corresponds to one target power, and then the target total power p=p1+p2+p3+ … +pn. And if the residual energy of the power supply device is W, discharging residual duration T=W/P.

In order to facilitate understanding of the method for determining the remaining discharge time, the method for determining the remaining discharge time is described in the practical application process, and specifically comprises the following steps:
1. acquiring vehicle history data (i.e., history data);
2. selecting characteristic points of each load;
for example, when a user turns on an air conditioner (i.e., a temperature adjusting device), an air conditioner set temperature (i.e., an air conditioner set temperature value), a set air volume (i.e., a set air volume value), and an ambient temperature (i.e., an ambient temperature value) may be selected as a feature point;
when a user uses 220V electric appliances (namely, an electric device), 220V switch states (namely, switch state values) can be selected as characteristic points;
3. taking the characteristic points of each load as input parameters, counting historical load power conditions of the cloud vehicle, and obtaining historical average power of each load;
4. calculating each load according to the real-time power change rate of each load at the vehicle endWeighting coefficients of individual loadsWhen the real-time power fluctuation is large, the weighting coefficient is increased, and cloud historical data of the load are referenced more;
5. calculates the real-time power of each load of the actual current vehicle,
6. the total power consumed by all loads is calculated, and the vehicle discharge remaining time (i.e., the discharge remaining duration) is calculated according to the battery remaining energy (i.e., the remaining energy of the power supply device) divided by the total power consumed by the loads (i.e., the target total power).
Based on the same inventive concept as the above-mentioned method for determining the remaining discharge time, the embodiment of the present application further provides a device for determining the remaining discharge time, and the device for determining the remaining discharge time provided in the embodiment of the present application is described below with reference to the accompanying drawings.
