Abstract
Fuel cell-battery hybrid systems for the powertrain, which have the advantage of emissionfree power generation and adapt to material transport and emission reduction, are
investigated. Based on the characteristics of the fuel cell system and the characteristics of
the electric forklift truck powertrain system, this work defines the design principle of the
control strategy to improve overall performance and economy. A simulation platform for
fuel cell and electric vehicles has been established. The optimal performance of the fuel
cell stack and the battery capacity were defined for the specific application. An energy
control strategy was defined for different operating cycles and operating conditions. Model
validation involved comparing simulation results with experimental data obtained during
VDI60 test protocol. The main parameters that influence the forklift performance were
defined and evaluated, such as energy loss, fuel cell operating conditions and different
battery charging cycles. The optimal size of the fuel cell stack of 11 kW and the battery of 10
Ah was determined for the specific load profile with the proposed control strategy. The
results obtained in this work forms the basis for an in-depth study of the energy management of fuel cell battery drive trains for forklift trucks.
