Uncertainties on the parton distribution functions (PDFs), in particular those of the valence quarks, can be constrained at LHC energies using the charge asymmetry in the production of W<sup>±</sup> bosons. This thesis presents a measurement of the electron channel, lepton charge asymmetry using 497 pb<sup>-1</sup> of data recorded with the ATLAS detector in 2011. The measurement is included in PDF fits using the machinery of HERAPDF and is found to have some constraining power beyond that of existing W charge asymmetry measurements.
