This paper analyzes the introduction of regenerative braking systems into DoD tactical vehicles, with a focus on Marine Corps logistics vehicles. The analysis addresses a regenerative braking system’s ability to provide a short-term energy source for ancillary systems as well as assisting in the vehicle’s propulsion to save fuel. Different means of incorporating regenerative braking systems are evaluated to determine the most efficient and effective alternatives (e.g., regenerative braking integrated into the drive-train and in-wheel regenerative braking systems). Other means of improving fuel efficiency and powering on-board systems are also evaluated, to include idle-reduction technology, improved batteries, and addition of solar panels. Each system is assessed for its potential to provide power for other on-board systems, such as C2 assets, as well as fuel savings. The potential payback period is assessed using cost-benefit analysis. Research on regenerative braking systems is reviewed as well as issues driving the integration of energy-saving systems and factors affecting the acquisition and integration of these technologies. This study helps decision-makers to make informed decisions about the potential use of regenerative braking systems in tactical logistics vehicles. While regenerative braking systems do provide an alternate power source of auxiliary power systems, they were found to not be a viable alternative at this point. Idle-reduction systems should be pursued.
