Energy harvesting technologies motivated researchers and manufacturers to develop a sustainable and eco-friendly power supply to drive low-power electronics. In electrified vehicles, regenerative automobile shock absorbers are currently receiving focus to harvest a part of the dissipated suspension’s kinetic energy. Despite other energy harvesting applications in automobiles, the car’s suspension works and dissipates kinetic energy as much as the vehicle moves on the road, which can be used in continuous vibration-to-electricity energy harvesting applications. This paper provides a full characterization of an arm-toothed rotary electromagnetic regenerative damper. The arm-toothed/flywheel mechanism converts the linear shock absorber’s motion to a rotational motion during both the compression and expansion strokes. The flywheel’s inertia helps to amplify the input speed to enhance the harvested power and provide smooth operation during random non-periodic excitations. A 2-DOF quarter model equipped with the arm-toothed energy-harvesting damper was built. The arm-toothed energy-harvester model is verified through test-bench results. The car regenerative suspension model has been entirely characterized concerning both the harvester and suspension parameters during simulations. To mimic a real-car traveling on roads, the regenerative suspension model was simulated under non-periodic ISO 8606 roads with different qualities and speeds. The results indicated that traveling on a Grade-C road with speeds between 20–100 km/h, the average power and voltage RMS outputs ranged between 5–24 mW and 0.75–1.65 V, respectively.
