The typical free charging session was one hour and 18 minutes, and consumed 42 kwh.
The info doesn’t embody information from Tesla’s Supercharger community. It is based mostly on the EVWatts dashboard, a DOE undertaking managed by Energetics consulting and utilizing a self-selected subset of EV homeowners, aiming at higher understanding charging patterns. It now consists of information from 50,712 cost ports, 14.16 million classes, and greater than 249 terawatt-hours of vitality.
