1. A method of characterizing a bundle of electrical cables, comprising:
- taking into consideration for at least one surface temperature of the cables;
first at least one sum of incoming heat fluxes calculated for each cable for a heating effect due to an electrical resistance of each cable passing a respective electric current, andsecond an outgoing heat flux calculated for a heat given off by the bundle into its environment in order to make a dimensioning of the cables compatible with their use, wherein making the dimensioning of the cables compatible with their use includes confirming that a predetermined level of heating is not exceeded,comparing the at least one sum of incoming heat fluxes to the outgoing heat flux to determine whether the bundle satisfies a predetermined heat flux constraint; and
evaluating, for at least one power cable of the bundle, a voltage drop calculated between two ends of the cable to determine whether the bundle satisfies a predetermined voltage drop constraint;
wherein the bundle of electrical cables includes a plurality of cables arranged in parallel.

Abstract
A method of characterizing a bundle (1) of electrical cables (2, 3, 4, . . . ), comprising taking into consideration for at least one surface temperature of the cables (Tsurface), firstly of at least one sum of heat fluxes (Φ1, Φ2, . . . , Φn) calculated for each cable (2, 3, 4, . . . ) for the heating effect due to the electrical resistance of each cable passing a respective electric current (i1, i2, . . . , in), and secondly of a heat flux (Φs) calculated for the heat given off by the bundle (1) into its environment in order to make the dimensioning of the cables (2, 3, 4, . . . ) compatible with their use.
