Beschreibung
Zusammenfassung:	The HV junction device (JD) comprises a first battery terminal (B+) for connecting the first battery pack terminal (BP2+) of the second battery pack (BP2) and a second battery terminal (B-) for connecting the second battery pack terminal (BP1-) of the first battery pack (BP1). Furthermore, the HV junction device (JD) comprises a high voltage output with a first high voltage load terminal (HVL+) and a second high voltage load terminal (HVL-) for connecting a high voltage load group with one or more high voltage loads. The HV junction device (JD) also comprises a high voltage input with a first high voltage charge terminal (HVC+) and a second high voltage charge terminal (HVC-) for connecting an electric vehicle supply equipment. The HV junction device (JD) comprises a first contactor (C-DC+) and a second contactor (C-DC-) and the first battery terminal (B+) is connected to the first high voltage charge terminal (HVC+) via the first contactor (C-DC+) and the second battery terminal (B-) is connected to the second high voltage charge terminal (HVC-) via the second contactor (C-DC-). Furthermore, the HV junction device (JD) comprises a third contactor (C-M+) and a fourth contactor (C-M-) and the first battery terminal (B+) is connected to the first high voltage load terminal (HVL+) via the third contactor (C-M+) and the second battery terminal (B-) is connected to the second high voltage load terminal (HVL-) via the fourth contactor (C-M-). The junction device (JD) comprises a fifth contactor (C-BP1) and a sixth contactor (C-BP2) and a node (N) connectable to the second battery pack terminal (BP2-) of the second battery pack (BP2) and the first battery pack terminal (BP1+) of the first battery (BP1) for providing a voltage level of the connection between the first battery pack (BP1) and the second battery pack (BP2). The node (N) is connected via the fifth contactor (C-BP1) to the first high voltage charge terminal (HVC+) and via the sixth contactor (C-BP2) to the second high voltage charge terminal (HVC-).
