AC and DC: where the conversion happens
The battery stores energy electrochemically and charges using direct current. AC and DC charging differ largely in where the electrical conversion is performed.
Canvas of Knowledge · 14 November 2026 · Illustrated explainerAC ROUTE
With AC charging, an onboard charger converts the incoming alternating current to DC. Its rating can limit the rate even when a wall unit offers more power.
DC ROUTE
With DC fast charging, the station performs the AC-to-DC conversion. Power reaches the battery through the vehicle’s high-voltage controls, subject to the battery’s permitted limits.
SYSTEMS CAN BE CLEVER
Lucid describes integrated charging and voltage-management hardware in its Wunderbox. Other architectures use different conversion arrangements; connector shape alone does not reveal the internal power path.
THE IDEA TO KEEPAC versus DC describes the power route, not a universal promise about charging speed.
