SHUNT CURRENT MEASUREMENT FEATURING TEMPERATURE COMPENSATION

摘要

The invention relates to a method for measuring an electric current (6) that is supplied by a vehicle battery (4) and is conducted across a shunt (28), said method involving: - detecting a measurement voltage (32) dropping across the shunt (28); - determining a difference in temperature (62) between two temperature points (47, 49) between which at least part of the shunt (28) is located and which are at a distance from one another in the direction of flow of the electric current (6); and - determining the electric current (6) on the basis of the detected measurement voltage (32) and the determined difference in temperature (62).
