The target vehicle may be an electric vehicle, and the electric vehicle may be a pure electric vehicle, a hybrid electric vehicle, or a fuel cell vehicle.
In order to facilitate understanding of the technical solutions provided in the embodiments of the present application, the technical solutions will be described below with reference to the accompanying drawings.
Referring to fig. 1, which is a flowchart of a method for evaluating an influence of a user usage behavior on aging of a battery pack according to an embodiment of the present application, the method may include:
s101: and acquiring user use behavior data, wherein the user use behavior data represents the use behavior of the battery pack by the user.
In the present embodiment, to determine the degree of influence of the usage behavior of the user on the life decay of the battery pack, the usage behavior data of the user is first acquired. The user use behavior data mainly comprises the driving modes of the user, such as the depth of an accelerator pedal and the depth of a brake pedal; charge and discharge habits, charge and discharge modes, vehicle use frequency and the like. The charging and discharging habit may reflect the charging and discharging operations of the battery pack by the user, such as recharging after the battery runs out, charging when the battery is turned upside down, plugging the battery terminal before the battery terminal is plugged in during charging, and the like. For some bad charging and discharging habits, the service life of the battery pack is greatly reduced. The charging and discharging modes can comprise a charging mode and a discharging mode, and the charging mode can comprise direct current fast charging and alternating current slow charging.
S102: and determining a life attenuation coefficient of the battery pack according to the user usage behavior data, wherein the battery pack attenuation coefficient represents the influence degree of the user usage behavior data on the life attenuation of the battery pack.
In a specific implementation, the life coefficient of the battery pack corresponding to the user usage behavior data may be determined according to the following two ways:
in an example, a functional relationship between the user usage behavior data and the life attenuation coefficient of the battery pack may be pre-constructed, and after the user usage behavior data is obtained, the corresponding life attenuation coefficient of the battery pack is determined by using the functional relationship.
In another example, the user usage behavior data is input into the decay correlation model to obtain a battery pack life decay factor. That is, a decay correlation model may be obtained in advance, and the user usage behavior data may be input into the decay correlation model as input data to obtain the life decay coefficient of the battery pack output by the decay correlation model.
The attenuation correlation model is generated by training according to the training user use behavior data and the classification labels corresponding to the training user use behavior data. The attenuation correlation model can be obtained specifically by:
1) acquiring the use behavior data of a training user and a label corresponding to the use behavior data of the training user.
For training, a decay correlation model is generated, and a large amount of training data, namely training user usage behavior data and a decay coefficient corresponding to the training user usage behavior data, can be obtained in advance. The training user usage behavior data can include various usage behavior data to ensure that the decay correlation model generated by training can identify various user usage behavior data and various application scenarios.
2) And training the parameters of the initial deep learning model according to the using behavior data of the training user and the labels corresponding to the using behavior data of the training user to obtain the attenuation correlation model.
When training is carried out, a corresponding label exists in each kind of training user use behavior data in the obtained training user use behavior data, the label is an attenuation coefficient, parameters of the initial deep learning model are trained by using the training user use data and the corresponding attenuation coefficient until the parameters are converged, and an attenuation correlation model is obtained.
In particular, the deep learning model can be trained in a supervised learning manner. In the actual training process, the deep learning model can calculate the contribution strength of the use behavior of each dimension in the use behavior data of the training user to the current corresponding attenuation coefficient, so as to train the weight coefficient in the deep learning model. For example, the calculation of the contribution strength may be performed using a model having a feature selection function.
In practical application, after the user usage behavior data is input into the attenuation correlation model, not only the attenuation coefficient corresponding to the user usage behavior data can be obtained, but also the contribution strength corresponding to the usage behavior of each dimension in the user usage behavior data can be obtained. For example, the user usage behavior has three dimensions of a, B, and C, the training generates an attenuation correlation model of a + B + C ═ Y, and the attenuation coefficient is Y, and the coefficients a, B, and C are the contribution strengths of the three feature dimensions. That is, the input of the obtained attenuation correlation model is the user usage behavior data, and the output is the life attenuation coefficient and the corresponding contribution strength of each dimension.
After the battery pack attenuation coefficient corresponding to the user usage behavior data is obtained in the above manner, a prompt message for prompting the user to maintain or avoid the usage behavior of the battery pack may be sent according to the battery pack attenuation coefficient. Specifically, when the attenuation coefficient of the battery pack is greater than or equal to a first preset threshold, prompting is performed to avoid similar use behaviors, so that damage to the battery pack is reduced; when the attenuation coefficient of the battery is less than a first preset threshold, the prompt is used to maintain similar usage behavior.
In a specific implementation manner, a usage behavior evaluation result may be obtained according to the life decay coefficient of the battery pack and the user usage behavior data, and the sent prompt message may include the usage behavior evaluation result, where the usage behavior evaluation result is used to reflect whether the user usage behavior corresponding to the user usage behavior data is normative or not, so that the user may intuitively know whether the current usage behavior of the user is normative or not.
Wherein the usage behavior evaluation result can be obtained by:
1) and obtaining an evaluation result corresponding to the use behavior data of each dimension.
In this embodiment, the user usage behavior data includes multiple dimensions of usage behavior data, for example, different dimensions such as a charging and discharging manner and a charging and discharging habit, and an evaluation result corresponding to each dimension of usage behavior data is obtained.
The evaluation result corresponding to each dimension use behavior data can be obtained by using a use behavior evaluation model generated by pre-training. Namely, the user usage behavior data and the battery pack attenuation coefficient are used as input data to be input into the usage behavior evaluation model, and the evaluation result corresponding to each dimension usage behavior data is obtained according to the output result.
The using behavior evaluation model is generated by pre-training according to the using behavior data of the training user and the label corresponding to the using behavior data of each dimension in the using behavior data of the training user. The training user usage behavior data comprises multi-dimensional user usage behavior data, and the label is an attenuation coefficient corresponding to the training user usage behavior and an evaluation result corresponding to each dimensional user usage behavior data in the training user usage behavior data. Specifically, a large amount of training data may be obtained, where the training data includes training user usage behavior data, an attenuation coefficient corresponding to the training user usage behavior data, and an evaluation result corresponding to each dimension usage behavior data in the training user usage behavior data, and the training data is used to train parameters of the initial model to generate a usage behavior evaluation model. The obtained training data may include various use behavior data and attenuation coefficients, so as to ensure that the user use behavior evaluation model generated by training may be applicable to various scenarios.
In particular, the deep learning model can be trained in a supervised learning manner. In the actual training process, the deep learning model can calculate the evaluation result of the current corresponding attenuation coefficient of the use behavior of each dimension in the use behavior data of the training user, so as to train and generate the use behavior evaluation model.
2) And obtaining a use behavior evaluation result according to the evaluation result corresponding to the use behavior data of each dimension and the weight coefficient.
After the evaluation result and the weight coefficient corresponding to the usage behavior data of each dimension are obtained, the evaluation result and the weight coefficient of the usage behavior data of each dimension can be weighted and summed to obtain the usage behavior evaluation result corresponding to the usage behavior data of the user. Wherein the weight coefficient is used for indicating the contribution strength of the usage behavior data of each dimension to the life decay coefficient of the battery pack. When the weight coefficient corresponding to the use behavior data of a certain dimension is larger, the influence of the use behavior data of the dimension on the service life attenuation of the battery pack is larger. For example, the user usage behavior data includes 3 dimensions of usage behavior data, the evaluation result corresponding to the first dimension of usage behavior data is a, and the weight coefficient is 0.6; the evaluation result corresponding to the second dimension use behavior data is b, and the weight coefficient is 0.3; the evaluation result corresponding to the third-dimension usage behavior data is c, the weight coefficient is 0.1, and the usage behavior evaluation result is 0.6 a +0.3 b +0.1 c. The evaluation result may be a specific evaluation score.
In some implementation manners, in order to improve the service life of the battery pack, a standard use behavior may be recommended to the user, specifically, the target user use behavior data whose use behavior evaluation result meets a preset condition is sent to the client, so as to prompt the user to use the vehicle according to the target user use behavior data.
According to the method, in order to detect the influence degree of the use behavior of the user on the life attenuation of the battery pack, the use behavior data of the user in the current period of time is obtained, and the use behavior data of the user can represent the use behavior of the user on the battery pack in the latest period of time. And obtaining a battery pack service life attenuation coefficient corresponding to the user use behavior data according to the user use behavior data, wherein the battery pack attenuation coefficient represents the influence of the use behavior of the user on the attenuation of the battery pack service life, and further the influence degree of the use behavior of the user on the battery pack performance can be quantitatively measured.
In addition, after the life attenuation coefficient of the battery pack is obtained, prompt information can be sent according to the life attenuation coefficient of the battery pack to prompt a user to keep the current using behavior or avoid the current using behavior. For example, when the life decay coefficient of the battery pack is large, it indicates that the current usage behavior will cause the battery life to decay greatly, so that the battery life is shortened, and the usage behavior should be avoided as much as possible in future use. Or when the life attenuation coefficient of the battery pack is smaller, the current use behavior is not harmful to the life attenuation of the battery, and the user can be prompted to keep the use behavior, so that the working performance of the battery pack is ensured.
