For this wiki's definition, Level 1, 2 and 3 are as follows
Level 1 = “0” kW - 1.92 (2) kW AC
Level 2 = 1.92 (2) kW - 19.2 (20) kW AC
The 19.2 kW - 24 kW AC is not available in US, Europe has 400V 3 phase compared to US 240 1 phase.
Level 3 = 24 (20) kW and up DC fast chargers
What AI says about the “official” EV charging levels.
Official EV Charging Levels (SAE J1772 Standard)
Level 1 (AC Charging) - Voltage: 120 V AC - Power: Up to ~1.92 kW - Connector (North America): J1772 or Tesla - Use case: Home outlets, emergency charging - Speed: ~3–5 miles of range per hour. This is the slowest official level.
Level 2 (AC Charging) - Voltage: 208–240 V AC - Power: Up to 19.2 kW (the official upper limit) - Connector: J1772 or Tesla - Use case: Homes, hotels, workplaces, public AC stations - Speed: ~20–40 miles of range per hour (varies by car’s onboard charger)
19.2 kW is the maximum official Level 2 power. Anything above that is not Level 2.
Level 3 (DC Fast Charging — officially called DCFC) - Voltage: 200–1000 V DC - Power: 24 kW up to 350+ kW - Connector: CCS, CHAdeMO, Tesla NACS - Use case: Road trips, highway corridors - Speed: 60–1000+ miles of range per hour (varies by car and charger)
The official standard doesn’t use “Level 3” in the technical documents — it uses DC Fast Charging or DCFC — but “Level 3” is widely used in public conversation.
19.2 kW AC → Officially Level 2 - 24 kW DC → Officially DC Fast Charging (DCFC)
There is no official “Level 2.5” or “slow Level 3” category, even though travelers often describe it that way.
