Ohio state police pulled over Andrew Boguslawski in January after they said he was going 85 mph in a 70 mph zone on Interstate 70.
Authorities said they found 48 explosives, four guns and a remote detonation device when they searched the vehicle.
The complaint alleges Boguslawski had several devices that fit the definition of improvised explosive weapons.
Boguslawski was scheduled for an initial court appearance Monday afternoon in Columbus. A message was left for his attorney.
Boguslawski had worked at an Indiana National Guard training center near Butlerville, Ind., and told troopers he had items for training purposes.
