Abstract:
Modern hybrid electric vehicles (HEVs) often employ all-electric powertrains
that utilise hybrid sources of power and energy; such as batteries, fuel cells
and ultracapacitors. This paper describes the design, simulation and
experimental verification of a power management control system that manages a
high voltage battery, a DC-DC boost converter and an ultracapacitor within a
front-wheel drive HEV in which the motive power for the vehicle comes from two
electrical machines. As part of this study, consideration is given to the
complete control system design life-cycle including plant model development,
algorithm design and software implementation on the target electronic control
unit (ECU). Off-line simulation and initial experimental results are presented
showing the vehicle operating on a powertrain dynamometer as one means of
demonstrating the ability of the ultracapacitor to limit the transient demands
placed on the battery during periods of vehicle acceleration and regenerative
braking.
