In the present work we utilize ACE/SWICS in-situ measurements of the properties of the solar wind outside ICMEs in order to determine whether, and to what extent are the solar wind properties affected by the solar cycle. We focus on proton temperatures and densities, ion temperatures and differential speeds, charge state distributions and both relative and absolute elemental abundances. We carry out this work dividing the wind in velocity bins to investigate how winds at different speeds react…
