Abstract

A computer-implemented method for predicting electric vehicle (EV) charging behavior of a driver. The method includes predicting when an EV needs to be charged, where the EV needs to be charged, and for how long the EV needs to be charged based on individualized characteristics of the driver or one or more passengers, weather conditions, and geospatial characteristics. The method further includes evaluating an availability of one or more EV charging stations located within a given radius of the EV and comparing a location of the one or more available EV charging stations, located within the given radius of the EV, to one or more desired locations of the driver of the EV. The method further includes determining an estimated waiting time at the one or more EV charging stations and scheduling an EV charging time at the one or more EV charging stations, based on the location and duration.

First claim

1 . A computer-implemented method for predicting electric vehicle (EV) charging behavior of a driver, the method comprising:
predicting when an EV needs to be charged, where the EV needs to be charged, and for how long the EV needs to be charged based on individualized characteristics of the driver or one or more passengers, weather conditions, and geospatial characteristics; evaluating an availability of one or more EV charging stations located within a given radius of the EV; comparing a location of the one or more available EV charging stations, located within the given radius of the EV, to one or more desired locations of the driver of the EV; determining an estimated waiting time at the one or more EV charging stations; scheduling an EV charging time at the one or more EV charging stations, based on the location and duration.

2 . The computer-implemented method of claim 1 , further comprising:
training a machine learning model to predict potential “range anxiety” for the driver, or the one or more passengers, of the EV; and establishing that the “range anxiety” is a causal relation with health or behavioral concerns of the driver, or the one or more passengers, of the EV.

3 . The computer-implemented method of claim 2 , further comprising:
triggering an amelioration action when the predicted “range anxiety” is above a given threshold, wherein the amelioration action comprises generating an actionable alert to the driver, or the one or more passengers, to charge the EV at a specific location, at a specific time, and for a specific duration.

4 . The computer-implemented method of claim 1 , further comprising:
training a machine learning model to predict possible idle time of the EV at a given time of day; and determining optimal charging parameters (location, duration, and time) while minimizing operation downtime of the EV.

5 . The computer-implemented method of claim 1 , wherein the predicted charging information of the EV automatically creates a calendar event, for the driver, with detailed metadata of the predicted charging.

6 . The computer-implemented method of claim 1 , further comprising:
optimizing the predicted charging of the EV based on economic costs and EV charging factors; and recommending a cost-effective EV charging, wherein the EV charging factors comprise a charging time, a location, a charger type and emission, a route, and health and behavioral concerns of the driver, or the one or more passengers.

7 . The computer-implemented method of claim 1 , further comprising:
training a modular neural network for a joint analysis of predicting an EV charging station and output of a weather-impact analysis to determine optimal EV charging factors.

8 . The computer-implemented method of claim 1 , further comprising:
stopping the EV charging when an actual charge level exceeds a predicted charge level required, by a predetermined amount, to reach a desired location.

9 . A computer program product, comprising a non-transitory tangible storage device having program code embodied therewith, the program code executable by a processor of a computer to perform a method, the method comprising:
predicting when an EV needs to be charged, where the EV needs to be charged, and for how long the EV needs to be charged based on individualized characteristics of the driver or one or more passengers, weather conditions, and geospatial characteristics; evaluating an availability of one or more EV charging stations located within a given radius of the EV; comparing a location of the one or more available EV charging stations, located within the given radius of the EV, to one or more desired locations of the driver of the EV; determining an estimated waiting time at the one or more EV charging stations; scheduling an EV charging time at the one or more EV charging stations, based on the location and duration.

10 . The computer program product of claim 9 , further comprising:
training a machine learning model to predict potential “range anxiety” for the driver, or the one or more passengers, of the EV; and establishing that the “range anxiety” is a causal relation with health or behavioral concerns of the driver, or the one or more passengers, of the EV.

11 . The computer program product of claim 10 , further comprising:
triggering an amelioration action when the predicted “range anxiety” is above a given threshold, wherein the amelioration action comprises generating an actionable alert to the driver, or the one or more passengers, to charge the EV at a specific location, at a specific time, and for a specific duration.

12 . The computer program product of claim 9 , further comprising:
training a machine learning model to predict possible idle time of the EV at a given time of day; and determining optimal charging parameters (location, duration, and time) while minimizing operation downtime of the EV.

13 . The computer program product of claim 9 , wherein the predicted charging information of the EV automatically creates a calendar event, for the driver, with detailed metadata of the predicted charging.

14 . The computer program product of claim 9 , further comprising:
optimizing the predicted charging of the EV based on economic costs and EV charging factors; and recommending a cost-effective EV charging, wherein the EV charging factors comprise a charging time, a location, a charger type and emission, a route, and health and behavioral concerns of the driver, or the one or more passengers.

15 . The computer program product of claim 9 , further comprising:
training a modular neural network for a joint analysis of predicting an EV charging station and output of a weather-impact analysis to determine optimal EV charging factors.

16 . A computer system, comprising:
one or more computer devices each having one or more processors and one or more tangible storage devices; and a program embodied on at least one of the one or more storage devices, the program having a plurality of program instructions for execution by the one or more processors, the program instructions comprising instructions for:
predicting when an EV needs to be charged, where the EV needs to be charged, and for how long the EV needs to be charged based on individualized characteristics of the driver or one or more passengers, weather conditions, and geospatial characteristics;
