His initial battery patent was awarded in 1903 and by 1904 he had established what was to become the Fritchle Automobile & Battery Company in Denver, Colorado. He was an early adaptor and developer of significant automotive technologies, such as regenerative braking and hybrid drivetrains, that did not reemerge on production vehicles of major car companies until late in the twentieth century.
