Do electric buses use AC or DC?

Although all battery electric bus batteries will store electricity in the form of DC, or direct current, power, the electric grid transmits and provides electricity in the form of AC, or alternating current, power. Therefore, a critical process of charging a BEV is the transformation of AC power into DC power.
