High Voltage Junction Device For A High Voltage Battery Of An Electric Vehicle And High Voltage Battery System

Teachings herein include a junction device for a high voltage battery of an electric vehicle. An example includes: a first terminal to connect the first terminal of a second battery pack; a second terminal to connect the second terminal of a first battery pack; a high voltage output with two load terminals to connect a high voltage load group; a high voltage input with two high voltage charge terminals to connect an electric vehicle supply; six contactors; and a node. The node is connected via the fifth contactor to the first high voltage charge terminal and via the sixth contactor to the second high voltage charge terminal.
