This paper presents a novel energy management strategy for a dual-engine system adopted in a series hybrid heavy-duty vehicle. The studied vehicle is powered by Li-ion batteries and two auxiliary power units (APUs). The model of the studied powertrain is established. Simulations under two Chinese-World Transient Vehicle Cycles (C-WTVCs)are conducted using the Charge Depleting and Charge Sustaining (CDCS)strategy. A power distribution strategy between two diesel engines is proposed to improve the system efficiency. The proposed power distribution strategy is compared with other strategies and can decrease the energy consumption by up to 8.7%. The dual-engine system is also compared with a conventional series hybrid heavy-duty vehicle with single engine. Simulation results show that different powertrains have similar energy efficiencies while the dual-engine system has additional merits such as good fault-tolerance ability.
