1. A method for charging an electric vehicle (EV) comprising:
determining an anticipated dispatch time for the EV based on predicted demand for a fleet of EVs, the fleet comprising the EV;
identifying a first charger having a first charging rate and a second charger having a second charging rate, the second charging rate less than the first charging rate;
determining a first charging rate curve based on battery data associated with the EV and the first charging rate, the first charging rate curve comprising a first plurality of charging rates over time that minimize battery degradation;
determining a second charging rate curve based on the battery data and the second charging rate, the second charging rate curve comprising a second plurality of charging rates over time that minimize battery degradation;
determining available dispatch times for the EV using the first charging rate curve and the second charging rate curve;
selecting the second charger based on degradation costs associated with the first charging rate curve and the second charging rate curve, the available dispatch times, and the anticipated dispatch time;
communicating, from a charging manager remote from the EV, the second charging rate curve to the EV; and
instructing, by the charging manager, the EV to maneuver to the second charger for charging at the second charging rate curve.
