The Effect of Ambient Temperature on the Costs of Battery Electric Vehicles Charging in the Microgrid

Global adoption and use of battery electric vehicles (BEVs) is limited by their prices, driving ranges and insufficient charging infrastructure. The driving range depends on vehicle efficiency, aging, battery capacity, driving conditions, ambient temperature, etc. The effect of ambient temperature on the costs of battery electric vehicles charging in a microgrid is analyzed in this paper. The schedule of charging/discharging electric vehicles is optimized so to minimize the energy costs of the microgrid according to the day ahead energy prices given per hour. The microgrid has photovoltaic panels with estimated energy production, and it is connected to the main grid. Optimization of the microgrid electricity costs is done in program Lingo.
