Abstract: Nowadays simulations are widely used in new systems design, and the same approach is applicable to Hybrid Electric Vehicle (HEV) development. In this paper several hybrid powertrain configurations for a typical construction machine – a backhoe loader – are investigated. Roading and lorry-loading performances of the backhoe loader are analysed by means of simulation studies. The simulation tool used for these studies is LMS Imagine.Lab AMESim. Several parameters are analysed, including the machine|s acceleration and top speed, maximum tractive effort, roading performance on a particular test circuit, battery current and state of charge, electric motor and engine power. The results clearly indicate the advantages and disadvantages of each hybrid powertrain configuration.

Keywords: construction equipment; hybrid electric vehicles; HEVs; series hybrid powertrains; parallel hybrid powertrains; split hybrid powertrains; regenerative braking; modelling; AMESim; simulation; powertrain configurations; backhoe loaders.
