In addition, the order of the steps may be rearranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Example one
Fig. 1 is a schematic flowchart of a vehicle charging safety protection method according to an embodiment of the present invention, where the method may be performed by a vehicle charging safety protection device, where the device may be implemented by software and/or hardware, and may be generally integrated in a charging platform such as a server. As shown in fig. 1, the method includes:
s101, acquiring charging process data corresponding to the target vehicle in the process that the target vehicle is charged through the charging pile.
The charging process data comprise first charging process data uploaded by the target vehicle and second charging process data uploaded by the charging pile.
The target vehicle represents an electric vehicle to be charged, and in the process of charging the electric vehicle, first charging process data may be correspondingly generated for the battery, and the first charging process data may include various information, for example, temperature information of the current battery, current charging voltage information, current charging current information, and the like, and the generated first charging process data is uploaded to the charging platform.
Correspondingly, the charging pile for providing the electric energy for the target vehicle can generate corresponding second charging process data in the charging process, the second charging process data can be information about whether the electric quantity of the charging pile is overcharged, the temperature information of the current charging pile, the voltage information of the current charging pile and the like, and the generated second charging process data are uploaded to the charging platform.
The charging platform is used for acquiring and monitoring first charging process data of a target vehicle and second charging process data of a charging pile in real time when the target vehicle is in a corresponding charging pile charging process, a pre-stored safety threshold value about battery index data of the target vehicle in the charging process can be contained in the charging platform, and a safety threshold value of the charging pile in the charging process can be contained in the charging platform.
And S102, evaluating the charging safety index of the target vehicle and the charging safety index of the charging pile according to the charging process data.
The charging safety index of the target vehicle can be evaluated according to the safety threshold corresponding to the obtained first charging process data. The evaluation mode can divide evaluation grades into the following grades according to vehicle data in historical charging or charging pile data in the historical charging obtained by the charging platform: no danger warning, moderate danger warning, severe danger warning, and the like. The charging vehicles and the charging piles upload correspondingly generated vehicle data in historical charging or charging pile data in historical charging to the charging platform in real time, so that the charging platform evaluates the charging safety indexes of the target vehicles and the charging safety indexes of the charging piles based on the historical data.
Taking battery temperature information in first charging process data obtained by a target vehicle as an example, if the battery temperature information is obtained according to temperature data in historical vehicle charging, taking a safety threshold corresponding to a charging safety index of the temperature information as an example of 30-40 degrees, and if the obtained temperature information of the current target vehicle is within the safety threshold, indicating that no danger warning exists currently; if the current temperature information difference is smaller than a first preset value (for example, 10%) of the safety threshold, outputting a moderate danger warning; and if the current temperature information difference value is larger than the preset value of the safety threshold value, outputting a severe danger warning and the like.
Accordingly, the charge safety index of the target vehicle may also be: evaluating a safety threshold corresponding to the current charging voltage information, evaluating a safety threshold corresponding to the current charging current information, and the like, wherein the evaluation mode is similar to the evaluation mode of the battery temperature information, and according to historical charging voltage data and charging current data obtained by a charging platform, the data information of the charging voltage and the charging current of the target vehicle is evaluated as follows: no danger warning, moderate danger warning, severe danger warning and the like, and outputting corresponding warning degrees and the like according to a preset safety threshold value.
Alternatively, the temperature information of the present battery, the voltage information of the present charge, and the current information of the present charge obtained by the target vehicle may be used as the whole of the evaluation, and when the evaluation is performed according to the historical data of the vehicle, a second preset value (for example, 10%) of the data according to the single-term average value is in the safety threshold range, if the second preset value is within the safety threshold, the corresponding evaluation is an a-level, and if the second preset value exceeds the safety threshold, the corresponding evaluation is a B-level. When the number of the obtained B grades of the charging platform is greater than a first preset number (for example, 2), a heavy danger warning is correspondingly output; if the number of B is less than the first preset number, a moderate danger warning is outputted correspondingly, and the specific evaluation manner is determined according to the information included in the acquired first process data, which is not limited herein.
Accordingly, the charging safety index of the charging pile can be evaluated according to safety threshold data corresponding to second charging process data obtained in the charging process of the target vehicle. For example, according to whether the electric quantity of charging pile overcharges information, the temperature information of charging pile at present and the voltage information of charging pile at present, also can divide into: the evaluation levels of the no-danger warning, the moderate-danger warning, the severe-danger warning and the like are similar to the evaluation mode of the safety index of the target vehicle, and the detailed description is omitted here.

The manner of intervening in the charging process may include: the charging platform sends early warning prompt information to vehicle owner side equipment (such as a target vehicle or a mobile terminal used by a vehicle owner) corresponding to the target vehicle, the charging platform automatically stops charging or automatically adjusts charging parameters (such as output current) of the charging pile, and the like.
Optionally, the intervention mode may be different according to different evaluation results. According to the embodiment, by taking the charging platform to obtain the battery temperature information as an example, through comparison with the pre-stored safety threshold data, when the output is the moderate danger warning, at the user side, information can be sent to the user mobile terminal, so that the user mobile terminal displays on a visual interface, for example, "the current battery temperature is abnormal, the moderate danger warning is output, the vehicle is suggested to be checked", the user is enabled to make sure that the current charging battery temperature is beyond the normal safety temperature range, the user can adopt a timely checking mode to make sure whether the current battery is abnormal, and if the current battery is abnormal, relevant repairing operation can be adopted. When the severe danger warning is output, the charging platform can remotely control the charging pile corresponding to the target charging vehicle to stop charging and send information to the user mobile terminal, so that the user mobile terminal displays the conditions of 'abnormal current battery temperature, outputting severe danger warning, stopping charging' and the like on a visual interface, and the user can timely find abnormal conditions, thereby avoiding dangerous accidents caused by abnormal battery temperature and realizing the protection of charging safety.
