Vehicle charging method, device, apparatus and vehicle

By adjusting the gain factor of the current request value, the current request value is gradually increased to stimulate the charging pile to release its charging capacity, which solves the problem of the charging pile not outputting according to its charging capacity, and improves charging efficiency and user experience.

AI Technical Summary

Technical Problem

The problem of poor charging efficiency caused by charging piles not outputting charging capacity may be due to multiple vehicles charging at the same time, resulting in reduced current output at the charging pile or a charging pile malfunction that prevents it from outputting current normally.

Method used

By adjusting the gain ratio of the current request value, the current request value is gradually increased to stimulate the charging pile to release its charging capacity. This includes defining the initial current request value and updating the gain ratio until the charging pile returns to normal or is determined to be faulty.

Benefits of technology

It increases the current output of the charging pile, shortens the charging time, improves charging efficiency and user charging experience, and promptly reminds users to replace the charging pile to avoid malfunctions.

Abstract

The application relates to the field of intelligent vehicles and provides a vehicle charging method, a vehicle charging device, a vehicle charging equipment and a vehicle. The method comprises the following steps: applying for charging from a target charging pile according to a current request value, obtaining a pile end output current value provided by the target charging pile to the current vehicle, wherein the current request value is less than a maximum current output value of the target charging pile; in response to the current request value and the pile end output current value meeting preset charging adjustment conditions, updating a gain multiplication factor coefficient of the current request value, and adjusting the current request value according to the updated gain multiplication factor coefficient; and reapplying for charging from the target charging pile according to the adjusted current request value. The technical scheme adjusts the output state of the charging pile, makes the charging pile increase the output of the charging current in response to the increased current request value, thereby releasing the charging capacity of the charging pile, the increase of the charging current shortens the charging time of the user for the vehicle, improves the charging efficiency of the vehicle, and further improves the charging experience of the user.
