Analysis of a Hybrid Light Tactical Vehicle Demonstrator: Considering Performance, Functionality, and Weight

Hybrid powertrain technology serves to improve performance, enable new functional capabilities, decrease fuel consumption, increase operational reach, and increase lethality by supporting advanced weapons systems. Several demonstrators have been developed for the Army, including those recently commissioned and tested by numerous programs over the last decade. This work examines the results of one of these demonstrators for a Light Tactical Vehicle (LTV) and analyzes tradeoffs in the components’ characteristics, including the battery size, energy, and power capabilities, specifically regarding the system’s ability to meet key performance and power generation requirements. Test data analysis coupled with a vehicle 1D simulation allowed for this work to be completed. Results show design implementation impacts and tradeoffs between vehicle weight, performance, EV-only range, and fuel consumption that can be utilized for system level optimization.
