Inverter

An inverter is power electronics that converts direct current into alternating current. In an electric vehicle, the traction inverter takes DC energy from the battery and supplies controlled AC to the electric motor. The term is sometimes used loosely for other power-conversion equipment, which causes confusion in EV charging. Converting incoming AC electricity into DC for a battery is an AC-to-DC conversion function performed by the onboard charger or by the power electronics inside a DC charge point. Bidirectional power converters can transfer energy in both directions, so their hardware may combine functions that older terminology treated separately.
