Abstract: Techniques are presented for the detection of whether an EV is using a household or other user location for charging. A machine learning model is trained on a training population of user locations using historical usage data and a label for a some of the user locations, typically a small proportion, indicating that an EV charges there, where the labels can, for example, be provided by a utility or derived from the EVs' telematics. The trained model can then be applied to un-labeled user locations' electricity usage data to detect EV charging, both assigning a label and a confidence value to the label. If telematics are available, for user locations at which EV charging is detected, the EV charging can be disaggregated from other electricity usage of the user location.
