To provide a switching arrangement which is improved to be usable a pre-charge resistor not only in order to pre-charge a capacitor, but also in a heating mode.SOLUTION: A switching arrangement 1 is provided in a motor vehicle 100 powered at least partially electrically. The motor vehicle 100 includes: an inverter device 2 for converting a DC voltage of a high-voltage battery 10 into a multi-phase AC voltage for a travel drive unit 20; an intermediate circuit capacitor 3 connected to the inverter device 2, and a pre-charge resistor 4. The pre-charge resistor 4 of the switching arrangement 1 is configured to: in a pre-charge mode, prevent occurrence of current spikes during charging of the intermediate circuit capacitor 3; and, in a heating mode 24, heat a coolant cooling the high-voltage battery 10, as well as, allow electrical current to flow from the inverter device 2 to the high-voltage battery 10 through the pre-charge resistor 4 so as to heat the high-voltage battery 10.SELECTED DRAWING: Figure 3
【課題】コンデンサをプリチャージするためにプリチャージ抵抗器を使用することができ、また加熱モードにおいて使用することができる、改善されたスイッチ装置を提供する。【解決手段】スイッチ装置1は、少なくとも部分的に電気的に動力が供給される自動車100に備えられる。自動車100は、高電圧バッテリ10のDC電圧を走行駆動部20のための多相AC電圧に変換するインバータデバイス2と、インバータデバイス2に接続されている中間回路コンデンサ3と、プリチャージ抵抗器4を備える。スイッチ装置1のプリチャージ抵抗器4は、プリチャージモードにおいては、中間回路コンデンサ3が充電される際の電流スパイク発生を防止し、加熱モード24においては、高電圧バッテリ10を冷却する冷却剤を加熱するとともに、プリチャージ抵抗器4を介しインバータデバイス2から高電圧バッテリ10へ電流を流すことにより、高電圧バッテリ10を加熱する。【選択図】図3
