Explosion accidents in oil tanks took place twice in the last three years in China. The simulation test on charge density and surface potential during filling gasoline into a tank has been conducted. The volume-averaged charge density was found to rise to a maximum about 20 min after the pump was started and then began to decrease. The surface potential rose steadily for about 30 min and then decreased during filling operation. The maximum of surface potential sharply increased when the filling rate rose.
