Method, device and equipment for estimating remaining charging duration of new energy automobile and medium

Abstract

The invention provides a new energy automobile remaining charging duration estimation method, device and equipment and a medium, the method comprises the steps that target configuration information, a real-time charge state and a target charge state are acquired, and the target configuration information comprises target automobile type information and charging pile real-time power information; for the target configuration information, inputting the real-time charge state and the target charge state into a corresponding duration estimation model, and determining target residual charging duration information, the duration estimation model corresponding to the target configuration information; and sending the target residual charging duration information to a user terminal, so that the user terminal displays the target residual charging duration information. According to the scheme provided by the embodiment of the invention, the residual charging duration of the new energy vehicle of each vehicle type under the corresponding charging power can be accurately estimated, so that the influence on the use experience of a user is avoided.

Description

technical field [0001] The invention relates to, but is not limited to, the technical field of new energy vehicles, and in particular, relates to a method, device, equipment and medium for estimating the remaining charging time of a new energy vehicle. Background technique [0002] New energy charging stations are sites for charging new energy vehicles. New energy vehicles include pure electric vehicles, extended-range electric vehicles and hybrid electric vehicles. There are technical differences between different types of new energy vehicles, resulting in various types of new energy vehicles. The actual charging power is different, and the new energy charging station is equipped with a variety of charging piles, which can charge various types of electric vehicles according to different voltage levels. [0003] At present, in order to estimate the remaining charging time of new energy vehicles, linear operations are used to calculate the remaining charging time through the ...

Problems solved by technology

[0003] At present, in order to estimate the remaining charging time of new energy vehicles, linear calculation is used to calculate the remaining charging time through the charging power of charging piles and the real-time state of charge of new energy vehicles. Since the state of charge of new energy vehicles is not linear during the charging process In addition, the charging efficiency of different models of new energy vehicles is different, and the charging efficiency of new energy vehicles of the same model is different under different charging powers, resulting in inaccurate estimates of the remaining charging time of new energy vehicles, and users cannot get Accurate remaining charging time affects user experience
