Abstract
Materials handling vehicles are considered one of the
potential early markets for fuel cells. In this
application, lifetime and reliability have been
identified as key parameters to be maximized. However,
typical work cycle of many materials handling and other
industrial vehicles, like forklifts, is characterized by
heavy and fast variations in power demand. This sort of
fast transient operation is not ideal for a fuel cell and
hence hybridizing it with different energy storages is
preferred.
A hybrid power source consisting of PEMFC,
ultracapacitors and lead-acid battery has been developed
on a large counterweight forklift. The energy storages
were connected directly in parallel without actual power
electronics in order to achieve simple structure and
avoid conversion losses. In this arrangement, the
lead-acid battery SoC and the internal resistance of
energy storages directly dictate the load distribution
between them. Only high current rated relays and a
Schottky-diode are used to control current flow between
energy storages and protect the fuel cell stacks.
