How long does it take to charge an EV?

Tesla Model Y (75 kWh): Level 1 (1.4 kW): ~54 hours 0-100%. Level 2 (7.2 kW): ~11 hours. Level 2 (11.5 kW): ~7 hours. DC Fast Charge (250 kW peak): 15-25 minutes to 80%. Fast charge tapers above 80% to protect battery.

What is the difference between Level 1, 2, and DCFC?

Level 1 (120V/12A): 1.4 kW, adds 4-5 miles/hour. Level 2 (240V/32-48A): 7-11.5 kW, adds 20-35 miles/hour. DCFC (CCS/CHAdeMO): 50-350 kW, adds 150-900 miles/hour (limited by onboard charger and battery thermal state).

Why does fast charging slow down above 80% SOC?

Above 80%, charging rate tapers (CC-CV charging curve) to prevent lithium plating and cell damage. Going from 10-80% often takes the same time as 80-100%. Most EV road trip planning stops at 80% to maximize miles gained per charging minute.
