Method for detection of plug-in electric vehicle charging via interrogation of smart meter data

摘要

A method and application that utilizes a signal processing algorithm is provided for detecting plug-in electric vehicle charging events through interrogation of smart meter data. The method is a form of non-invasive load monitoring that allows the utility to track plug-in electric vehicle charging events in real time or over extended periods. These parameters are suitably flexible so as to accommodate diverse electric vehicle technologies and a range of electric vehicle owners' charging habits. Application of the method facilitates the integration of electric vehicles into utilities' electrical grids, protection of the utilities' assets, geographic mapping of electric vehicle owners and charging events, managed charging through communication between the utility and the vehicle or owner, managed charging through the offer of time of use rates for electric vehicle owners, and an enabling technology to accompany other Smart Grid functions such as Vehicle-to-Grid distributed energy storage.

1. A non-transitory computer readable medium having computer executable program code embodied thereon, the computer executable program code configured to cause a computing device to:
monitor a residence over time for the presence of individual charging events; detect an individual charging event at the residence and identify it as a plug-in electric vehicle charging event through signal processing analysis of interval consumption data for the residence based on a threshold level of total kWh consumption, a defined duration at which kWh consumption remains above this threshold, a leading edge increase in kWh consumption, and a lagging edge decrease in kWh consumption.
