Mercedes-Benz Cars plants in Germany to be supplied with CO2-neutral energy from 2022

Green Car Congress

A key element of this change is the conversion of production micro-grids from an alternating current (AC) to a direct current (DC) architecture—“Industrial Smart DC Grids”. However, today’s production grids are powered by alternating current—which has to be converted.
