In this report we represent the results of the investigation of the localized states of few extra electrons in a deformable chain, which are described by the many-component NLSE. It is shown that in the case of two extra electrons the minimum of energy corresponds to the singlet bisoliton state. In the triplet state two electrons form two almost free solitons separated by some distance which is determined by the competition between Pauli repulsion and their mutual attraction due to the nonadiabatic interaction with the phonon subsystem.
