In response to growing concerns on the environment and the need to save energy, working machine manufacturers\ud have started to consider hybridization of their products. This paper presents a systematic modelling approach\ud to identify the most promising hybrid configurations for existing skid loaders. This approach involves\ud accuratemodelling of the existing version (fittedwith a conventional power train),model validation bymatching\ud the simulation results with experimental tests, design by modelling of different hybrid configurations and corresponding\ud cost/benefit analysis

“…The same happens in the case of construction vehicles: in [20,21] the authors defined a specific duty cycle for the hybridization process of a skid loader, while in [22][23][24][25][26] different duty cycles were used for analyses on compact excavators. The need of a standard duty cycle for excavators has been emphasized in many articles, such as [27], and a good attempt at standardization was made by the Japanese Construction Mechanization Association with the test procedure explained in [28], but they are still not globally recognized.…”

“…Examples of this trend include the various projects on the hybridization of compact agricultural tractors [18,19,136,137], where the main objectives are the possibility of downsizing the ICE and addition a pure electric mode, which could be useful for less demanding tasks or for use inside greenhouses. However, even if there are some cases of hybrid compact vehicles below 56 kW, like the hybrid skid loader studied in [20,21], their higher efficiency does not justify their higher upfront cost.…”

Electrified vehicles have undergone great evolution during the last decade because of the increasing attention paid on environmental sustainability, greenhouse gas emissions and air pollution. Emission regulations are becoming increasingly tight, and governments have been allocating multiple funds to facilitate the spreading of the so-called green mobility. In this context, steering towards electrified solutions not only for passenger vehicles, but also for compact off-highway vehicles extensively employed, for instance, on construction sites located in urban areas, warehouses, and greenhouses, is essential even if seldom considered. Moreover, the electrification of compact off-highway machinery may allow manufacturers to increase their expertise in and lower the costs of these alternative solutions, while gathering useful data to be applied in bigger and more remunerative off-highway vehicles. In fact, while electric automobiles are as of now real alternatives for buyers, off-highway vehicles, regardless of the application, are mostly in the research and experimental phase, with few of them already on the market. This delay, in comparison with the passenger automotive industry, is caused by different factors, mostly related to the different tasks of off-highway vehicles in terms of duty cycles, productivity performance parameters and user acceptability. The aim of this paper is to give an overview of the many aspects of the electrification of compact off-highway vehicles, to highlight the key differences between on-highway and off-highway vehicles and to summarize in a single source of information the multiple solutions investigated by researchers and manufacturers.

h i g h l i g h t sAn innovative on board hydraulic system fed by a KERS is presented. A complete model of the proposed system is presented. The model is validated on experimental data. a r t i c l e i n f o a b s t r a c tMany conventional truck and working machines are equipped with additional hydraulic tooling or manipulation systems which are usually fed through a mechanical connection with the internal combustion engine, involving a poor efficiency. In particular, this is a common situation for industrial vehicles whose mission profiles involves a relevant consumption of energy by the on board hydraulic systems, respect to the one really needed for only traction purpose. In this work it is proposed an innovative solution based on the adoption of a system aimed to recover braking energy in order to feed an efficient on board hydraulic actuation system. The proposed system is then adopted to a real application, an Isuzu truck equipped with a hydraulic tooling for garbage collection. A prototype of the system has been designed, assembled and tested showing a relevant improvement of system efficiency and the feasibility of the proposed approach. In the paper the proposed solution is presented, showing the simulation models and preliminary validation results including experimental devices assembled to perform the tests.
