This report analyzes EV use in TNC fleets from 2016 through 2018. Data sets from TNCs and charging service providers are used to analyze charging and use patterns of EVs within TNC fleets. The emissions benefits of EV use withing TNC fleets is quanitfied, assessments of EVs to perform TNC services are made, and the effects of EV use within TNC fleets on charging behavior of non-TNC EVs is understood.

Key findings



The emissions benefits of electrifiying EVs in a TNC fleet is nearly three times greater than the benefits from electrifying a privately owned vehicle.



Using an EV in lieu of a gasoline-powered vehicle to provide full-time TNC service reduces CO2 emissions by nearly 40 kg/car/day.



Continued availability of free chargers will do much to encourage TNCs and TNC drivers to go electric but may not be economically feasible at a large scale, especially given the outsize per-vehicle charging demand of TNC fleets.



Use of public chargers by TNC EVs is low but not negligible during nighttime hours, and moderately high from about 12:00 p.m. to midnight. Use dips between 6:00 p.m. and 8:00 p.m.—presumably because this time period coincides with the period of highest demand for TNC-provided rides.
