Electric vehicle charging has me confused. Are we charging with AC or DC? When I plug into a home outlet, does the power go straight to the battery or is there a circuit in the car? What determines charging speed? How do fast-charging stations work, and how does the DC current there adapt to the car’s AC system? Can you explain the process technically but simply?

As you mentioned, when you plug it into the home outlet, it's actually AC power, and the vehicle's onboard charger converts it to DC to charge the battery. At fast charging stations, since DC power is supplied directly, it bypasses the vehicle's AC-DC converter, allowing you to reach up to 80% in just 30 minutes—my car went from 20% to 80% in 25 minutes, very convenient.
