SHUNT CURRENT MEASUREMENT WITH TEMPERATURE COMPENSATION
First Claim
1. A method for the measurement of an electric current by an electrical conductor in a vehicle, said electrical conductor comprised of two conductor sections, between which a shunt is connected, the method comprising:
- determining an electrical measuring voltage delivered via the shunt;
recording of a first corrective voltage in the direction of the electric current, considered an up-circuit of a given point on the shunt;
recording of a second corrective voltage in the direction of the electric current, considered a down-circuit of said point on the shunt; and
determining the electric current based upon the electrical measuring voltage recorded and a difference between the first corrective voltage and the second corrective voltage.

Abstract
A method for the measurement of an electric current by an electrical conductor in a vehicle, the electrical conductor having two conductor sections, between which a shunt is connected, the method including determining an electrical measuring voltage delivered via the shunt; recording a first corrective voltage in the direction of the electric current up-circuit of a given point on the shunt; recording a second corrective voltage in the direction of the electric current down-circuit of the point on the shunt; and determining the electric current based upon the electrical measuring voltage recorded and a difference between the first corrective voltage and the second corrective voltage.
