A National Renewable Energy Laboratory (NREL) project, funded by GM, found that an ultracapacitor-based energy storage system (ESS) in a Saturn VUE BAS (belt alternator starter) mild hybrid performed at least as well or better than the NiMH battery system in the production hybrid.

While there are no 48 V models in production today, these are the next phase of an incremental multi-generational product plan for cost-effective improvement in vehicle fuel economy. There is not a clear winning 48 V power system architecture and associated components. Noting a predicted 3.7 GWh of the total market.

Monthly fuel economy of the retrofitted Honda Civic during the first 9 months of the fleet test. DOE researchers attributed the significant fuel economy reduction for May, June, and July as most likely being due to significant mountain driving and the likely use of the vehicle’s air conditioning.

The main advantage of HEVs and PHEVs is the existence of individual subsystems, e.g., the internal combustion engine, the electric machines (motor and generator), and the energy storage system (battery) that can power the vehicle either separately or in combination. —Shaltout et al.

Fuel cell buses are currently in a pre-commercial phase, although there are buses being deployed in regular transit operations and transit fuel cells being offered with conventional warranties. Most fuel cell development in the transit sector has focused on the full-size 40-foot buses, with the fuel cell providing primary propulsion.

The green line reflects FEV’s 15% cost reduction for the power transmission/clutch/motor subsystems from 2010 to 2013, assuming that the same reductions are achieved in all parts of the hybrid system. annual cost reductions plus implementation of higher-power Li-ion batteries that should reduce future battery costs by at least $500.
