The invention relates to a vehicle (2) having an on-board electrical system (1) with:-a traction battery (5),-a charging port (6) for coupling to a DC charging station (4),-a positive potential line (HV + L),-a negative potential line (HV-L),-a reference potential line (ML), and-a voltage measuring device (SV1, SV2) between the positive potential line (HV + L) and the reference potential line (ML) and/or between the negative potential line (HV-L) and the reference potential line (ML). According to the invention, a DC-DC converter (DC/DC +, DC/DC-) is arranged in the positive potential line (HV + L) and/or in the negative potential line (HV-L), an isolating element (T +, T-) is arranged in the positive potential line (HV + L) and/or in the negative potential line (HV-L), a processing unit (7) is provided, the processing unit is designed and adapted to analyze the measured voltage (s) and to control the opening of the individual isolation elements (T +, T-),-specifying one or more trigger criteria relating to the measured voltage (s),-specifying one or more trigger criteria relating to the measured voltage (s),-specifying one or more trigger criteria relating to the individual isolation elements (T +, T-); and-the processing unit (7) is designed and adapted to control the individual isolation elements (T +, T-) to open upon determining that a trigger criterion or one or all of a plurality of trigger criteria has occurred.
本发明涉及一种具有车载电气系统(1)的车辆(2),该车载电气系统具有:‑牵引电池(5),‑用于与直流充电站(4)耦合的充电端口(6),‑正电位线(HV+L),‑负电位线(HV‑L),‑参考电位线(ML),以及‑位于正电位线(HV+L)与参考电位线(ML)之间和/或位于负电位线(HV‑L)与参考电位线(ML)之间的电压测量装置(SV1、SV2)。根据本发明规定,‑在正电位线(HV+L)中和/或在负电位线(HV‑L)中布置有直流‑直流转换器(DC/DC+、DC/DC‑),‑在正电位线(HV+L)中和/或在负电位线(HV‑L)中布置有隔离元件(T+、T‑),‑设置有处理单元(7),该处理单元被设计和适配成分析测得的一个或多个电压以及控制各个隔离元件(T+、T‑)断开,‑指定涉及测得的一个电压或测得的多个电压的一个或多个触发标准,以及‑处理单元(7)被设计和适配成在确定发生了触发标准或多个触发标准之一或所有触发标准时,控制各个隔离元件(T+、T‑)断开。
