102, if the battery data meets a preset battery abnormal condition, generating prompt information and control information aiming at the battery data;
the battery abnormal condition can be preset, whether the battery data meets the battery abnormal condition or not is judged by comparing the battery data with the battery abnormal condition, if so, the use of the battery assembly is determined to be abnormal, and then prompt information and control information are generated aiming at the battery data.
In practical application, a database can be built aiming at the acquired battery data, then an identification model is built according to the database, whether the currently acquired battery data meets the battery abnormal condition is judged through the identification model, and further, when the identification model identifies the battery data meeting the battery abnormal condition, prompt information and control information can be output aiming at the battery data.
The embodiment of the invention does not limit the architecture and algorithm of the identification model specifically, and only the identification model is required to identify the battery data meeting the abnormal condition of the battery and output prompt information and control information.
Step 103, the prompt information is sent to a preset terminal;
the prompt information may include abnormal conditions of the battery pack and a control mode matched with the control information.
The mobile terminal corresponding to the vehicle owner of the vehicle can be preset as a preset terminal, the prompt information is sent to the preset terminal after the prompt information is obtained, and the vehicle owner can perceive the prompt information through the prompt information.
Or, identification information corresponding to a vehicle owner of the vehicle is preset, and the identification information may be an identification in an Application (APP). And transmitting the prompt information to a user corresponding to the side identifier in the application program, so that the vehicle owner can perceive the prompt information through a terminal running the application program.
Or the preset terminal is a vehicle-mounted terminal in the vehicle, and the prompt information can be perceived when the vehicle owner is positioned in the vehicle cabin by outputting the prompt information to the vehicle-mounted terminal. Through outputting prompt information to a preset terminal, a vehicle owner can sense that the battery assembly of the vehicle is abnormal, corresponding maintenance control is needed to be carried out on the battery assembly, and a control mode of the control information is displayed to a user, so that the vehicle owner can know the maintenance mode if the maintenance is carried out.
104, when a control instruction of the preset terminal aiming at the prompt information is received, the control information is sent to a battery module of the vehicle; the battery module is used for executing the control information.
When the vehicle owner determines that the corresponding maintenance control needs to be performed on the battery, preset input (such as gestures, voices, texts and the like) can be performed in a preset terminal so as to generate a control instruction for the prompt information.
When a control instruction sent by a preset terminal is received, the control information is sent to a battery module in a vehicle through a vehicle-end gateway by a communication protocol of unified diagnostic service (UDS, unified Diagnostic Services), and the battery module executes the control information so as to improve the abnormal condition of the battery assembly, thereby carrying out certain maintenance on the battery assembly.
In the embodiment of the invention, the battery data of the vehicle are acquired; if the battery data meets the preset battery abnormal condition, generating prompt information and control information aiming at the battery data; the prompt information is sent to a preset terminal; when a control instruction of the preset terminal aiming at the prompt information is received, the control information is sent to a battery module of the vehicle; the battery module is used for executing the control information, so that one end of battery data is obtained, whether the battery assembly of the vehicle is abnormal or not can be identified, prompt information is output to a preset terminal corresponding to a vehicle owner when the battery assembly is abnormal according to the battery data, the vehicle owner can sense the abnormal situation of the battery assembly, when a control instruction aiming at the prompt information is received, the vehicle owner is determined to need to improve the abnormal situation of the battery assembly, the control information generated aiming at the battery data is sent to the battery module, the control information is executed by the battery module, the abnormal situation of the battery assembly is improved, the battery assembly is further maintained to a certain extent, and the service life and the safety of the battery are improved. Compared with the method provided by the user manual in the prior art for maintaining the battery, the method provided by the embodiment of the invention can enable a vehicle owner to sense whether the abnormal condition occurs in the battery assembly or not and actively decide whether control information needs to be issued or not so as to improve the abnormal condition of the battery assembly.
In an alternative embodiment of the present invention, the battery module includes a mutual battery management control system BMS (Battery Management System) and a battery assembly; the battery data is generated by the BMS through detection of the battery assembly; the BMS is configured to execute the control information.
The BMS can monitor the battery assembly, and then obtain battery data. When the BMS obtains the control information, the battery pack can be correspondingly controlled according to the control information, for example: control the charge and discharge of the battery assembly, regulate the temperature, etc.
In an example, the steps 101-104 may be performed by a cloud end connected to a vehicle through a vehicle network, the prompt information is output to a preset terminal provided with a designated APP, the vehicle owner perceives the prompt information through the APP, and the battery module in the vehicle end performs control information to maintain the battery assembly, so as to form a battery assembly maintenance mode of three-terminal closed loop of 'cloud end-APP-vehicle end'.
In another example, the BMS is provided with a storage medium storing battery data, and the above steps 101 to 103 may be performed by the BMS, and the BMS directly performs the control information after receiving the control command without redundantly transmitting the control information in step 104.
In yet another example, steps 101-104 described above may be performed by other components in the vehicle having data transmission and data processing functions, such as: a vehicle machine in a vehicle.
In an alternative embodiment of the present invention, the battery data includes feature information and feature parameters corresponding to the feature information; the battery abnormal condition includes a preset value corresponding to the characteristic information.
And comparing the characteristic parameters of the same characteristic information with preset values, so as to judge whether the battery data meet the abnormal conditions.

a substep S11, when the temperature detection value is greater than the first preset temperature threshold value and the duration is greater than the temperature threshold value, generating a prompt message based on the temperature detection value;
substep S12, generating control information corresponding to a temperature adjustment device in the battery module based on the temperature detection value.
When the temperature detection value is greater than the first preset temperature threshold value and the duration time is greater than the temperature threshold value, the battery assembly is in the environment which is higher than the temperature threshold value within a period of time, and the environment is abnormal, prompt information is generated based on the temperature detection value and used for prompting a user that the battery is in the high-temperature environment for a duration time.
The temperature adjusting device is arranged in the battery module, and the control information corresponding to the temperature adjusting device is generated, so that when the vehicle receives the control information, the temperature of the battery assembly can be reduced by controlling the temperature adjusting device, the time that the battery assembly is in a high-temperature environment is shortened, the service life of the battery assembly is prolonged, and the effect of maintaining the battery assembly is achieved.
In one example, the temperature regulating device may be a fan.
In an optional embodiment of the present invention, the characteristic information includes a power consumption characteristic, and the characteristic parameter includes a first frequency of less than a first preset percentage of a remaining power corresponding to the power consumption characteristic; the preset value comprises a preset frequency corresponding to the power consumption characteristic; step 102 comprises:
a substep S21, when the first frequency is greater than the preset frequency, generating a prompt message based on the first frequency;
Step S22, generating a second preset percentage larger than the first preset percentage according to the preset difference value;
a substep S23 of generating control information based on the second preset percentage; and the battery module is used for outputting alarm information when detecting that the current residual electric quantity of the battery module is reduced to the second preset percentage.
When the first frequency is larger than the preset frequency, determining that the battery assembly is abnormal in electric quantity use, and determining a second preset percentage larger than the first preset percentage. And generating control information based on the second preset percentage, and outputting alarm information when the residual electric quantity of the battery assembly is reduced to the second preset percentage when the battery module receives the control information so as to prompt a user of the current residual electric quantity, so that the situation that the user uses the battery to be lower than the first preset percentage can be reduced to a certain extent.
For example: the first preset percentage can be 5%, the preset frequency can be 3 times/30 days, namely when the battery assembly is determined to be within 30 days according to the battery data, when the residual electric quantity is reduced to less than 5%, the battery assembly is determined to have abnormal electric quantity use, and the second preset percentage is generated to be 10%, so that the battery assembly can be promoted to charge before the residual electric quantity is reduced to 5% to a certain extent when the battery assembly is detected to be reduced to 10%, and further the battery assembly is prevented from being maintained by reducing the residual electric quantity to below 5%.
In an optional embodiment of the present invention, the feature information includes a fast charging feature, and the feature parameter includes a first charging number, a first fast charging number duty ratio, and a first full charging number duty ratio within a first preset time corresponding to the fast charging feature; the preset value comprises a first preset times threshold value, a first preset quick charge proportion and a first preset full charge proportion which correspond to the quick charge characteristic; step 102 comprises:

For example: the first preset time may be 30 days, the first preset number of times threshold may be 10 times, the first preset quick charge ratio may be 90%, and the first preset full charge ratio may be 60%. The first fast charge frequency is a ratio of the fast charge frequency to the first charge frequency, and the first full charge frequency is a ratio of the full charge frequency to the first charge frequency, and the full charge frequency is a condition of charging the electric quantity of the battery assembly to 100% of the current capacity.
The first target full charge percentage is less than 10% of the preset standard full charge percentage, and the first target fast charge current may be less than 20% of the preset standard fast charge current.
By reducing the percentage of full charge and the charging current, the impact of frequent and rapid charging by the user on the battery assembly is reduced.
In this alternative embodiment, the control information further includes a valid number of times, for example, 5 times, that is, the number of times the battery pack is cycled to charge the control information, and the control information is invalidated after the number of times the cycled charge reaches the valid number of times.
In an optional embodiment of the present invention, the feature information includes a full charge feature, and the feature parameter includes a second charge number, a second fast charge number duty ratio, and a second full charge number duty ratio within a second preset time corresponding to the fast charge feature; the preset value comprises a second preset time threshold value, a second preset quick charge proportion and a second preset full charge proportion which correspond to the quick charge characteristic; step 102 comprises:
step S41, when the second charging frequency is greater than a second preset frequency threshold, the fast charging frequency proportion is greater than a second preset fast charging proportion, and the full charging frequency proportion is greater than the second preset full charging proportion, generating prompt information based on at least one of the fast charging frequency proportion and the full charging frequency proportion;
Step S42, determining a second target full charge percentage smaller than a preset standard full charge percentage and a second target fast charge current smaller than a preset standard fast charge current;
substep S43 generates control information based on the second target full charge percentage and the second target fast charge current.
For example: the second preset time may be 30 days, the second preset number of times threshold may be 10 times, the second preset quick charge ratio may be 60%, and the second preset full charge ratio may be 90%. Wherein the second fast charge frequency is the ratio of the fast charge frequency to the second charge frequency, the second full charge frequency is the ratio of the full charge frequency to the second charge frequency,
the first target full charge percentage is less than 10% of the preset standard full charge percentage, and the first target fast charge current may be less than 20% of the preset standard fast charge current.
By reducing the percentage of full charge and the charging current, the impact of frequent full charge by the user on the battery assembly is reduced.
In this alternative embodiment, the control information further includes a valid number of times, for example, 5 times, that is, the number of times the battery pack is cycled to charge the control information, and the control information is invalidated after the number of times the cycled charge reaches the valid number of times.
It may be appreciated that the first charging frequency and the second charging frequency may be equal or unequal, the first preset time and the second preset time may be equal or unequal, the first target full charge percentage and the second target full charge percentage may be equal or unequal, and the second target fast charge flow may be equal or unequal.
