Nowadays, the use of mobile technologies is rising at an alarming scale. Due to this, more powerful and efficient mobile applications are needed in order to keep up with this trend. Since there exists several mobile platforms (iOS, Android, etc…), each one with different SDK (Software Development Kit) tools and specific development capabilities, application development becomes more complicated and expensive. The challenge is to come up with a solution that allows us to deploy in different platforms using a single SDK tool and maintaining the same performance as the native application. A suitable solution is crossplatform. In this paper, we present a survey of cross-platform creation approaches with an emphasis on the MDA (Model Driven Architecture) approach as it is one of the most promising cross platform approaches. We also identify and discuss the main desirable requirements of any cross-platform technology.

Abstract.Within the next few years, Electrified vehicles are destined to become the essential component of the transport field. Consequently, the charging infrastructure should be developed in the same time. Among this substructure, Charging stations photovoltaic-assisted are attracting a substantial interest due to increased environmental awareness, cost reduction and rise in efficiency of the PV modules. The intention of this paper is to review the technological status of Photovoltaic-Electric vehicle (PV-EV) charging stations during the last decade. The PV-EV charging station is divided into two categories, which are PV-grid and PVstandalone charging systems. From a practical point view, the distinction between the two architectures is the bidirectional inverter, which is added to link the station to the smart grid. The technological infrastructure includes the common hardware components of every station, namely: PV array, dc-dc converter provided with MPPT control, energy storage unit, bidirectional dc charger and inverter. We investigate, compare and evaluate many valuable researches that contain the design and control of PV-EV charging system. Additionally, this concise overview reports the studies that include charging standards, the power converters topologies that focus on the adoption of Vehicle-to grid technology and the control for both PV-grid and PV standalone DC charging systems.
