DC fast chargers facilitate higher power EV charging, which requires much larger AC-to-DC rectifiers, so the converter is built as part of the EV charging station and DC power is supplied directly to the vehicle, bypassing the onboard converter.

Public EV charging stations are typically found street-side or at retail shopping centers, government facilities, and other parking areas.
| FactSnippet No. 1,264,852 |
Private EV charging stations are typically found at residences, workplaces, and hotels.

Level 2 EV charging equipment was permanently wired and fastened at a fixed location under NEC-1999.
| FactSnippet No. 1,264,854 |
Level 3 EV charging equipment used an off-vehicle rectifier to convert the input AC power to DC, which was then supplied to the vehicle.
| FactSnippet No. 1,264,855 |
AC EV charging stations connect the vehicle's onboard EV charging circuitry directly to the AC supply.

Commonly, though incorrectly, called "Level 3" EV charging based on the older NEC-1999 definition, DC EV charging is categorized separately in the SAE standard.
| FactSnippet No. 1,264,857 |
The Avcon butt-and-pin connector supported Level 2 and Level 3 EV charging and was described in the appendix of the first version of the SAE J1772 recommended practice; the 2001 version moved the connector description into the body of the practice, making it the de facto standard for the United States.

This, together with the lack of EV charging stations, has reduced the number of electric models available in Europe.
| FactSnippet No. 1,264,859 |
Some EV charging stations have been criticized as inaccessible, hard to find, out of order, and slow, thus slowing EV adoption.

Mobile EV charging involves another vehicle that brings the charge station to the electric vehicle; the power is supplied via a fuel generator, or a large battery.
| FactSnippet No. 1,264,861 |
Wireless EV charging uses inductive EV charging mats that charge without a wired connection and can be embedded in parking stalls or even on roadways.
