    DESIGN OF SOLAR PHOTOVOLTAIC FOR ELECTRIC VEHICLES CHARGING UNIT

    Machines. Technologies. Materials., Vol. 13 (2019), Issue 12, pg(s) 522-531

    In this paper, we design and simulate a 20 kW solar on grid power charging unit for electric vehicles at Al-Hussein Bin Talal University (AHU)/Maan-Jordan by using a Bluesol 3.0, Sketch Up 2018 software.
    Two scenarios are considered; one where number of vehicles is five in the interval (8 am – 12 pm) & five vehicles in the interval (12 pm – 4 pm) and time of charge half of battery capacity four hours and the second scenarios where number of vehicles is eight in the interval (8 am – 12 pm) & eight vehicles in the interval (12 pm – 4 pm) and time of charge half of battery capacity four hours. We conclude that the system is efficient and very useful to the electric vehicles users in the university. In addition, the system is reducing the CO2 emissions annually from generating power by 28.4 tons of CO2.

  • DYNAMIC MODEL OF USING POWERED LITHIUM-ION BATTERIES FOR EV / HEV APPLICATIONS

    Machines. Technologies. Materials., Vol. 8 (2014), Issue 2, pg(s) 29-31

    model of charging and discharging of the battery is validated experimentally with a traction battery used in EV / HEV. An interesting feature of this model is the simplicity for extracting of the dynamic parameters of technical specifications of the battery. Only two points on the curve for the discharge of the battery in the steady state are required to obtain the necessary parameters. The model of the battery is included in the simulation using the LabJack U12 in the programming environment LabVIEW2012 for EV / HEV applications. The results show that the model can accurately represent the dynamic behavior of the battery during use of EV / HEV vehicles.
