The value of "vehicle to grid" integration into warehouse logistics management : case of Slovenian retailer
Matjaž Knez, Péter Bajor, 2011, izvirni znanstveni članek

Opis: Wide-scale application photovoltaic energy sources for electricity production purposes is quite a challenge in Slovenia. The nature of sun is unpredictable, and the Slovenian National Grid has no significant storage opportunities today - if the V2G (vehicle-to-grid) solutions could be competitive in the near future we could prepare for the special circumstances: the batteries of electrically driven forklifts could provide attractive storage functions for renewable electricity storage. The following paper presents an overview of some "environmental background approaches" to show the complexity of this innovative system and to show the value of V2G technology and its application in warehouse logistics.

Electric forklifts with vehicle to grid technology for efficient warehouse energy management
Matjaž Knez, Péter Bajor, 2012, izvirni znanstveni članek

Opis: From an electric utility perspective, the sun is an intermittent electrical generator, tolerable in huge quantities, but increasingly difficult to manage. The nature of sun is unpredictable, and the Slovenian National Grid has no significant storage opportunities - if the V2G (vehicle-to-grid) solutions could be competitive in the near future it could prepare for special circumstances: the batteries of electrically driven forklifts could provide attractive storage functions for renewable electricity storage and for backupping the electrical national grid. This paper shows the study of the current research findings on the ŽVehicle to Gridʼ innovative concept and a proposed theoretical model of Forklift-to-Grid integration into energy management of a warehouse. Analyses of data, calculations of the economic value and of the profitability of the proposed business model yielded positive results that fully confirm the thesis that the integration of environmentally friendly renewable energy sources and new technologies into the logistic processes can improve logistics management while minimizing the negative impact of business on the environment.

Green logistics - a solar warehouse concept
Matjaž Knez, Péter Bajor, Sebastijan Seme, 2011, izvirni znanstveni članek

Opis: Transportation and logistics are responsible for climate change as they produce greenhouse gases and contribute to the increasing share of fossil fuels, such as oil, in global energy consumption. Supplying the required energy for the transport and logistics sector in an environment-friendly way (based on electric or hydrogen fuels) is one of the main challenges for mankind. Material handling processes have a significant energy demand in warehouse operations, and the application of electricity-driven vehicles and equipment is widely accepted. With the effective use of available green electricity sources - like photovoltaic and wind energy - in the warehouse, we could provide energy for these operations. This article, based on laboratory data, describes a solar-warehouse concept and analyzes the critical parameters, such as energy demand of processes and vehicles, the characteristics of consumption and production, the alternative solutions of electricity storage and fast-charging.
