AC vs DC — Why It Matters
Level 1 and 2 chargers output AC (Alternating Current), which must be converted to DC by your vehicle's onboard converter before it can charge the battery. The capacity of this converter varies — premium models like some Tesla or BYD vehicles can accept the full 22kW, while budget models may be limited to 7kW.
Level 3 DC chargers bypass this limitation entirely by converting power externally and feeding DC directly into the battery. The only limit is the battery pack's ability to accept and dissipate heat from fast charging. Nearly all modern EVs can handle 50kW DC or more, with premium models accepting 300kW+.
