Charging time for Electric Vehicles

Current electric vehicle charging system technologies fall into one of three standardized levels. Note that time to charge depends significantly on the characteristics of an individual vehicle, especially its battery type and chemistry.

Level 1: 120V AC, plug in to a standard wall outlet. These are included in all electric vehicles sold. Time to charge: 8-14 hours.

Level 2: 240V AC, special SAE J1772 connector. Customers may confuse this with the quick charge below. Time to charge: 4-8 hours.

DC quick charge: 500V DC, plug standards still in development. The Society of Automotive Engineers (SAE) is working on a J1772 Combo Connector that combines the connections for Level 2 and DC in one connector. Time to charge: as little as 15 minutes.
