Patent ID: 7659639

Claim:
A connection unit for the connection of electrical and/or electronic components to a pole of a motor vehicle battery, comprising: a first conductor section having a first conductor connectable to the battery pole; a second conductor section that originates from the first conductor section and includes a bypass conductor and a main conductor, to which at least one electrical and/or electronic component can be connected in each case; an interruption unit, by which an electrical and/or electronic component connected to the main conductor can be electrically isolated from the battery; the bypass conductor being uninterrupted so that an electrical and/or electronic component connected to the bypass conductor cannot be isolated from the battery by the connection unit; and a sensor for the measurement of a battery current and/or of a battery voltage having a lead for connection to an external evaluation unit for a motor vehicle battery management system wherein the sensor is arranged in the second conductor section and connected directly to the bypass conductor.
