The wide adoption of electric vehicles (EVs) is required for deep decarbonisation of transportation sector. The vast majority of EVs use lithium-ion batteries and their driving ranges are reduced under cold weather conditions due to excessive need for heating the battery and the driver cabin. In this paper, probabilistic modeling and simulation of large-collections of EV charging are presented and the impacts on power generation portfolio is investigated for the case of the UK. Particularly, the extra energy and power demands are quantified across different regions. Extensive simulations reveal that cold weather necessities an additional 630 MW of peak power when compared to optimal ambient temperatures. Simulation results further show that the hourly carbon intensity of the power grids could increase by 25% during cold days with low renewable generation. The problems pertinent to temperature effects on EV charging require greater attention as EVs are becoming the main mode of transport in the next decade.
