We investigate, in terms of production from pulsars and their nebulae, thecosmic ray positron and electron fluxes above $\sim10$ GeV, observed by theAMS-02 experiment up to 1 TeV. We concentrate on the Vela-X case. Starting fromthe gamma-ray photon spectrum of the source, generated via synchrotron andinverse Compton processes, we estimated the electron and positron injectionspectra. Several features are fixed from observations of Vela-X and unknownparameters are borrowed from the Crab nebula. The particle spectra produced inthe pulsar wind nebula are then propagated up to the Solar System, using adiffusion model. Differently from previous works, the omnidirectional intensityexcess for electrons and positrons is obtained as a difference between theAMS-02 data and the corresponding local interstellar spectrum. An equal amountof electron and positron excess is observed and we interpreted this excess(above $\sim$100 GeV in the AMS-02 data) as a supply coming from Vela-X. Theparticle contribution is consistent with models predicting the gamma-rayemission at the source. The input of a few more young pulsars is also allowed,while below $\sim$100 GeV more aged pulsars could be the main contributors.
