      The paper proposes a hybrid plasma model modification to take into account nonelastic particle collisions leading to changes of ion charge states. Particle recharge and ionization kinetics is described by a collision integral, quasilinear in distribution function, which was obtained using small ion velocity and energy change approximations for nonelastic collisions.
      A numerical solution of a kinetic equation for the plasma ion component is defined by a particle method including a way to account collisions specially developed based on splitting by physical processes. Numerical results are given for two test problems related to recharge kinetics in moving plane plasma flows.
