Predicting battery electric vehicle charging on the electrical grid : A study of the future power demand in Västerås

Abstract: Personal vehicles stand for almost 20% of total greenhouse gas emissions and to conform with the Paris Agreement, a switch to battery electric vehicles (BEV) is key. This switch will cause an enormous increase in electricity use and could cause major problems for the electrical grid. This study of the BEVs impact on the electrical grid, uses statistics of vehicles on road, important parameters of popular car series, statistics on driving range, and literature of where and when charging happens. Three different scenarios of BEV adoption for 2030 were studied, calc 56%, low 17%, and high 62%. This study found that the maximum peak demand of the year would increase 5.9%, 1.6%, and 6.1% respectively during the 10th hour of the average December day. If this demand increase is not considered in grid infrastructure planning, it might stall or slow down BEV adoption.
