Ellet was born at Penn's Manor in Bucks County, Pennsylvania, son of Charles Ellet Sr. and Mary Israel. His brother Alfred W. Ellet also became a civil engineer and later a brigadier general in the Union Army during the Civil War. Their grandfathers on both sides served in the American Revolutionary War. Their maternal grandfather, Israel Israel, was a member of Pennsylvania's Committee of Safety and a recognized active patriot. Ellet married Elvira Augusta Stuart Daniel on November 7, 1837 in Lynchburg, Virginia. Her father was Virginia justice William Daniel and her mother was Margaret Baldwin. Her family was one of the First Families of Virginia and owned enslaved persons, although Ellet would not. Judge Daniel's father had served as an ensign during the Revolutionary war under Captain Arda Allen, and his wife's maternal grandfather Dr. Cornelius Baldwin had served as a surgeon for the patriot cause throughout the conflict. The Ellets' Virginia-born daughter, Mary V. Ellet Cabell, helped found the Daughters of the American Revolution and became its member n. 6. Their son Charles Rivers Ellet also served as a colonel in the Union Army.
Early career and education
Ellett worked as a rodman, measuring for the Chesapeake and Ohio Canal and making drawings. Benjamin Wright promoted him to Assistant Engineer of the Fifth Residency, but in 1830, he resigned to continue his studies in Paris. Charles Ellett studied civil engineering at École nationale des Ponts et Chaussées in Paris, France, and in 1832 submitted proposals for a suspension bridge across the Potomac River. In 1842, he designed and built the first major wire-cable suspension bridge in the United States, spanning 358 feet over the Schuylkill River at Fairmount, Philadelphia, Pennsylvania. He designed the record-breaking Wheeling suspension bridge over the Ohio River at Wheeling, West Virginia in 1848, and a 770-foot suspension footbridge at Niagara Falls at the same time. His other civil engineering accomplishments include supervising both the James River and Kanawha Canal in Virginia and the Schuylkill Navigation improvements in Pennsylvania, He also constructed railroads in those states. Ellet developed theories for improving flood control and navigation of mid-western rivers. In 1849 he had advocated the use of reservoirs, built in the upper reaches of drainage basins, to retain water from the wet season that could be released during periods of low water to improve navigation; to some degree this also would tend to lessen the level of flooding during high flow. In 1850, the Secretary of War, conforming to an Act of Congress, directed Ellet to make surveys and reports on the Mississippi and Ohio Rivers with a view to the preparation of adequate plans for flood prevention and navigation improvement. His very complete report had considerable influence on later engineering thought and navigation improvements. His Report of the Overflows of the Delta of the Mississippi River helped to reshape New Orlean's waterfront. George Perkins Marsh published Man and Nature fourteen years later, but it was Ellet who first noted in writing that the artificial embankments created an overflowing delta. However, only decades later would his assertions be taken seriously and used in flood control decisions.
Military designs, service and death
In September 1854, the 250-ton accidentally rammed and sank the 2,794-ton. This incident convinced Ellet that with the development of steam propulsion, ramming would be a very effective form of naval combat. He was unable to persuade the U.S. Navy of this, so he published the pamphlet Coast and Harbor Defenses, or the Substitution of Steam Battering Rams for Ships of War in late 1855, hoping to gain the interest of the public. When the Civil War broke out, Ellet renewed his advocacy. The Navy still ignored him, but in March 1862, Secretary of War Edwin M. Stanton, familiar with his work on the Wheeling Suspension Bridge among other projects appointed Ellet colonel of engineers, and authorized him to form the United States Ram Fleet on the Mississippi River. Ellet converted several river steamers to rams, and by June his fleet was ready. As captains of the other rams, he appointed his brothers, his nephews, and his son Charles Rivers Ellet. On June 6, Colonel Ellet led the rams in the Battle of Memphis as captain of. During this complete Union victory, Queen of the West and Monarch both rammed and sank the Confederate flagship. Ellet was wounded during the battle—the only Union casualty. He died of his injuries in a hospital in Cairo, Illinois 15 days later.

Ellet's remains were returned to Philadelphia and buried in historic Laurel Hill Cemetery overlooking the Schuylkill River. The U.S. Navy named a destroyer to honor the Ellet family. USS Ellet was in service in 1939-46 during World War II.
