ELECTRIC DRIVE ARRANGEMENT AND METHOD FOR ITS OPERATION

Abstract

When charging a high-voltage battery at a DC charging station, a first step opens charging contactors, closes switching elements, and charges the high-voltage battery via the on-board charger and to transfer charge from one partial battery to the other partial battery or vice versa by an inverter. In a second step, when the high-voltage battery has been warmed up to a predetermined target temperature by the recharging process, operation of the inverter is stopped, the charging contactors are closed and in parallel with this is charged charging via the onboard charger and charged via the charging contactors, and the on-board charger is then deactivated and the charging process continues exclusively via the charging contactors.
