Improved energy supply for non-road electric vehicles by occasional charging station location modelling

The Sustainability of Integrating Contactless Occasional Charging in Electric Vehicle Material Handling

“…Investigations for charging station allocation in the BEV environment noted the most suitable application to be a maximal (gradual) covering model in order to meet the requirements of BEV recharging (Frade et al, 2011;Gimé nez-Gaydou et al, 2014), which goes in line with the approach for optimised charging station allocation for occasional recharging in industrial applications with reference to sustainability factors (Fekete et al, 2016).…”

“…As the shown values include energy efforts for additional charging station approaching as well as charging time reductions due to additional material handling equipment movements, it can be stated at this point that occasional charging bears the potential to increase the availability of UBE, whereas advanced charging station allocation based on indeed process knowledge can increase UBE by up to 60% (see also Fekete et al, 2016). The executed analyses showed, that an increased value of recharge energy was not necessarily synonymous to an increased downsizing potential since other factors such as process energy consumption, additional drive distance, transmission efficiency and minimal required battery capacity influence the vehicle (component) design, so that lower additional UBE in several cases showed similar results in reference to the systems overall sustainability.…”

“…As the illustration shows, the more flexible definition of the Eij covering distance results in an increased catchment area whereas the impact to sustainability needs a further revision. The results on additional usable battery energy (UBE) being realised through occasional recharging present an intermediate step towards the investigations on sustainability (see also Fekete et al, 2016). Figure 4.…”

“…As the comparison of existing framework properties and research environment demands revealed, existing models or methods neglect investigations focussing on electrical charging station allocation for occasional recharging as well as the necessary focus on process structures and its inherent potentials. Therefore the impact from occasional charging and charging station allocation was still underdeveloped, so that the model for Occasional Charging Station Location (OCSLM) was designed in order to enable comprehensive analyses on charging system implementation, its impact to the defined sustainability factors and to identify potential areas for system improvements (see also Fekete et al, 2016).…”

“…The cordless alternative bears several advantages, such as minimised handling efforts, fast connectivity and the opportunity for occasional, intra process charging, whereas also negative impact from decreased transmission efficiency emerge (Lee & Lorenz, 2011). This research project is based on previous research findings (see also Fekete et al, 2016) that focused on the simulation of optimal charging infrastructure allocation in reference to the maximisation of chargeable battery energy, and further investigates the impact from sustainability factors such as transmission efficiency, energy conversion and related CO2 emissions to the design of the charging infrastructure. The investigation analyses the impact from technology implementation to economic and ecologic sustainability of the transportation system, consisting of trucks and similar non-road electric transportation vehicles, in reference to an optimised charging infrastructure allocation based on the fundamental structures of Lean and Green Manufacturing.…”
