Abstract
A connection module for an electrical energy storage device of a motor vehicle includes a first connection element and a second connection element for connecting to the electrical energy storage device and to a traction network. The connection module includes busbars which connect the first connection element and the second connection element to one another. The connection module further includes a primary current measurement element and a secondary current measurement element, wherein the secondary current measurement element operates contactlessly. A power supply system for a motor vehicle is also provided.
Claims11
A connection module for an electrical energy storage device of a motor vehicle, comprising:
- a first connection element and a second connection element for connecting to the electrical energy storage device and to a traction network;
- a plurality of busbars connecting said first connection element and said second connection element to one another;
- a primary current measurement element;
- a secondary current measurement element, said secondary current measurement element being a contactlessly operating current measurement element;
- said first connection element having a first contact and a second contact, said first contact and said second contact extending parallel to one another;
- said first contact being configured as a flat strip with a substantially rectangular cross section such that said first contact has narrow sides and wide sides;
- said second contact being configured as a flat strip with a substantially rectangular cross section such that said second contact has narrow sides and wide sides;
- a first one of said narrow sides of said first contact and a first one of said narrow sides of said second contact facing inwardly toward one another;
- a second one of said narrow sides of said first contact and a second one of said narrow sides of said second contact facing outwardly away from one another and being spaced further apart from one another than said first one of said narrow sides of said first contact and said first one of said narrow sides of said second contact;
- and
- said secondary current measurement element being disposed between said first contact and said second contact of said first connection element in order to detect a measurement magnetic field formed when a current flows through said busbars.
