Article: Tracked vehicle physics-based energy modelling and series hybrid system optimisation for the Bradley fighting vehicle Journal: International Journal of Electric and Hybrid Vehicles (IJEHV) 2020 Vol.12 No.1 pp.1 - 14 Abstract: A hybrid electric tracked ground vehicle (HETGV) can reduce military fuel usage, however a review of current tools determined they are not suitable to estimate HEGTV performance. Based on topographic data and vehicle attributes, this research developed an estimation tool by creating a model to determine tracked vehicle energy and fuel requirements, and using these requirements, created a HEGTV cost and performance optimisation for the Bradley fighting vehicle energy system. The optimised design reduced fuel consumption by 15%, and met the vehicle's peak power requirement of 365 kW, with a recommended configuration of a 135 kW generator and 100 kWh battery, and an estimated drivetrain and fuel cost of $155,000. This analysis concludes by articulating the operational and tactical impacts of increased fuel efficiency. Inderscience Publishers - linking academia, business and industry through research
