Not by plugging in. An EV cannot be connected to a charger while it is moving, and onboard generators are not used in battery EVs. What every EV does is regenerative braking: when you slow down, the motor works as a generator and returns some energy to the battery, which extends range in city driving. Dynamic wireless charging, where coils in the road charge moving vehicles, is being researched and piloted but is not available for ordinary drivers.
Ways an EV Gains Energy
| Method | Available? |
|---|---|
| Regenerative braking | Yes, all EVs |
| Solar roof panels | A few models; small amounts |
| Plug-in charging | Only when parked |
| Dynamic wireless road charging | Pilots and research only |
| Towing behind another vehicle to charge | Not recommended; most makers prohibit flat towing |
Plan Instead
Charge at home overnight and plan fast-charging stops on trips; see where to find EV charging stations. For more on wireless charging, see what is EV wireless charging.
A Level 2 home charger such as the EVDANCE EV-ACS4005T 40A NACS portable charger or EVDANCE EV-AC04001U 40A J1772 portable charger starts every day with a full battery.
Frequently Asked Questions
Does regenerative braking fully charge the battery?
No; it recovers part of the energy used.
Can a generator in the trunk charge an EV while driving?
Not practical or safe.
Will roads charge EVs in future?
Dynamic wireless charging is being piloted; wide use is not yet available.
