Assessment method of electromobile charging demand based on vehicle electron identifying and device thereof

Abstract

The invention relates to an assessment method of electromobile charging demand based on vehicle electron identifying. And the steps of the method are achieved by constructing function modules to combine into a function module framework mainly through computer programs which are stored in computer readable storage medium. According to the vehicle electron identifying information of the electromobile, a charging pile which is connected with the electromobile acquires an actual charging model of the charging last time from a control cloud end, pre-estimates charging time according to a charging saturation value, the power saving value of a cell and the actual charging model of the charging last time, and hereby establishes a charging evaluation model in a present charging period. Then in the charging of this time, charging will be conducted according to the charging evaluation model, in this way, under the circumstance of cell aging, the charging pile will charge the cell according to the latest charging condition in a nearly saturated charging interval, thus keeping a faster charging rate and getting a full charge.

Description

technical field [0001] The present invention relates to the field of electric vehicle charging demand, and in particular to a method for evaluating electric vehicle charging demand based on vehicle electronic identification. In the steps of the method, functional modules can be established and combined into a functional module framework, which is mainly stored in a computer-readable storage medium. computer program to achieve. Background technique [0002] With the rapid development of electric vehicles, the popularity of electric vehicles is becoming more and more widespread. With the increase of the battery life of electric vehicles, the battery will age due to long-term charging and discharging actions.

With the increase of the battery life of electric vehicles, the battery will age due to long-term charging and discharging actions. The aging of the battery will affect the charging rate and battery storage of the battery. The current charging demand assessment method for electric vehicles is usually based on The charging power and battery capacity of the new rechargeable battery at the factory are used to evaluate the charging demand. In the case of battery aging, the average charging rate of the battery in the near-saturated charging range and the rated charging rate of the battery will change. The storage capacity and the rated battery storage capacity will change. If the charging pile still charges the battery at the rated average charging rate and battery storage capacity, the charging speed will be slow, and the battery cannot even be fully charged.
