Switching device for charging the battery of an electric vehicle at present and future DC charging infrastructures and a method for operating the switching device

摘要

The present invention provides a switching device for the galvanic isolation or connection of an at least two-pole battery terminal, an at least two-pole inverter terminal and a at least two-pole charger terminal comprising at least one battery contactor (BS1, BS2) each having a battery terminal pole (B1, B2) and at least one charger contactor (LS1, LS2), each with a charger connection pole (L1, L2), wherein a battery contactor (BS1, BS2) with a charger contactor (LS1, LS2) is connected in series between the respective battery connection pole (B1, B2) and the charger connection pole (L1, L2) and a center tap between the battery contactor (BS1, BS2) and the battery contactor Charger contactor (LS1, LS2) is connected to the respective inverter connection pole (W1, W2).
