The invention relates to a battery disconnecting unit (100) for disconnecting a battery system (200) having at least one battery cell (5) from an electrical system (300). The battery disconnecting unit (100) comprises a first terminal (2), a second terminal (4), a first switching element (S1), a second switching element (S2) and a current measuring resistor (6). In this case, a first connection of the first switching element (S1) is connected to a first connection of the current measuring resistor (6), and a second connection of the first switching element (S1) is connected to the second connection (2). In this case, a first connection of the second switching element (S2) is connected to a second connection of the current measuring resistor (6), and a second connection of the second switching element (S2) is connected to the second connection (4).
本发明涉及一种用于将具有至少一个电池组电池(5)的电池组系统(200)与电气系统(300)断开的电池组断开单元(100)。在此,该电池组断开单元(100)包括第一端子(2)、第二端子(4)、第一切换元件(S1)、第二切换元件(S2)和电流测量电阻(6)。在此,第一切换元件(S1)的第一连接端与电流测量电阻(6)的第一连接端连接,并且第一切换元件(S1)的第二连接端与第二端子(2)连接。在此,第二切换元件(S2)的第一连接端与电流测量电阻(6)的第二连接端连接,并且第二切换元件(S2)的第二连接端与第二端子(4)连接。
