The invention relates to an electrical energy store (1) for a motor vehicle for supplying at least one vehicle component of the motor vehicle, comprising at least two store branches (S1, S2, S3, S4) extending geometrically next to one another, each of which has a plurality of connected store units (2), the memory units each have at least one memory cell (3); at least one branch connector (C1, C2, C3) for connecting the memory branches (S1, S2, S3, S4) in series, said branch connector having a breaking device (T1, T2, T3) for detecting and interrupting a fault current circuit (K1, K2, K3, K4) formed by an undesired electrical connection between the two memory branches (S1, S2, S3, S4) and by the at least one branch connector (C1, C2, C3), the disconnecting device (T1, T2, T3) has a controllable disconnecting unit (F1, F2, F3) for disconnecting the at least one branch connector (C1, C2, C3) and a current sensor (I1, I2, I3) for detecting a branch current flowing through the at least one branch connector (C1, C2, C3); and a control device (6), which is designed to detect at least one fault current circuit (K1, K2, K3, K4) as a function of the detected branch current and to actuate the at least one breaking unit (F1, F2, F3) in order to interrupt the fault current circuit (K1, K2, K3, K4).

    本发明涉及一种用于机动车的电能量存储器(1),该电能量存储器用于为机动车的至少一个车辆部件供电,该电能量存储器具有:至少两个在几何上并排延伸的存储器支路(S1、S2、S3、S4),所述存储器支路分别具有多个连接的存储器单元(2),所述存储器单元分别具有至少一个存储器单体(3);至少一个用于将所述存储器支路(S1、S2、S3、S4)串联连接的支路连接器(C1、C2、C3),所述支路连接器具有断路装置(T1、T2、T3),用于识别和中断通过在两个存储器支路(S1、S2、S3、S4)之间的不希望的电连接和通过所述至少一个支路连接器(C1、C2、C3)形成的故障电流回路(K1、K2、K3、K4),所述断路装置(T1、T2、T3)具有用于断开所述至少一个支路连接器(C1、C2、C3)的能被控制的断路单元(F1、F2、F3)和用于检测流经所述至少一个支路连接器(C1、C2、C3)的支路电流的电流传感器(I1、I2、I3);以及控制装置(6),该控制装置设计用于根据所检测的支路电流识别至少一个故障电流回路(K1、K2、K3、K4)并且操控所述至少一个断路单元(F1、F2、F3)以中断所述故障电流回路(K1、K2、K3、K4)。
