Abstract:

 The ambient temperature has prominent impact on auxiliary power load, battery performance and traffic conditions of electric vehicles (EVs), thus leading to different charging demands. Quantifying the influence of ambient temperature on charging demands is of great significance to analyze the impacts of EV charging on power grids and plan appropriate charging facilities, etc. A charging load calculation method considering temperature factor is proposed in this paper. The Monte Carlo simulation method is adopted to calculate the total charging load using the data of available range and driving demand of EVs. Taking Guangzhou city as example, simulation results show that EV charging load changes with different ambient temperature, and charging load at a higher or lower temperature day is much higher than at the normal day; charging load of different kinds of EVs are influenced by temperature to different extents and temperature has a more notable influence on electric buses which have a longer daily driving mileage.

Key words:  electric vehicle (EV), Monte Carlo simulation, charging load, ambient temperature
