Distance Until Charge Prediction for Vehicles
First Claim
1. A vehicle comprising:
- a traction battery; and
at least one controller programmed to, in response to a first ignition cycle after a charging of the traction battery, output a distance until charge prediction that is based a plurality of selected distance estimates from filtered sets of historical data having a variance less than a threshold and derived by filtering historical data based on a time and a day of the first ignition cycle.

Abstract
A vehicle includes a traction battery and a controller programmed to, in response to a first ignition cycle after a charging of the traction battery, output a distance until charge prediction based on one or more selected distance estimates from filtered sets of historical data that are derived by filtering historical data based on a time and a day of the first ignition cycle. The selected distance estimates may be from filtered sets having more than a predetermined number of members. The selected distance estimates may be from filtered sets having a variance that is less than an overall historic variance. The filtered sets may include members of an unfiltered set based on a time of day and day of week.

10. An energy management system for a vehicle comprising:
at least one controller programmed to, in response to a first ignition cycle after a charging event, output a distance until charge prediction based on an average of selected distance estimates from a plurality of filtered sets of historical data, wherein the filtered sets are derived from an unfiltered set according to a day of week and a time of day of the first ignition cycle. - View Dependent Claims (11, 12, 13, 14, 15, 16)
