No phone can charge direct on 5V, and no EV battery can charge direct on 120/230/240V. That would be bad. Onboard the device is the actual battery charger - which is responsible for managing and guarding the unique battery chemistry to that phone/car. That does the conversion from "whatever the input power is" to "exactly what the battery needs".
