Arrangement for Determining Characteristic Variables of an Electrochemical Energy Store

Abstract

An arrangement for determining characteristic variables of an electrochemical energy store comprises a gradient sensor with a bridge circuit including anisotropic magnetoresistive resistance elements. The arrangement additionally comprises a conductor through which a current from the energy store flows during operation of the energy store. The conductor includes a first section configured to primarily magnetically influence a first side of the bridge circuit and a second section configured to primarily magnetically influence a second side of the bridge circuit. The first section and the second section are arranged with respect to the bridge circuit in such a manner that a flow of current through the conductor produces a measurable electrical voltage across the bridge circuit.
