This article presents a novel electric vehicle (EV) charging system model. The model introduces power constraints in the grid‐to‐battery converter to improve modelling accuracy. Simulation results of the presented model indicate EV charging impact on a low‐voltage electricity grid. Even though most of the battery charging load is spread evenly during desired times (e.g. off‐peak load during night), power constraints of the EV model result in narrow peak loads. Plug‐in EVs bring additional load to the electricity grid. If not managed properly, high EV deployment may lead to unnecessary grid investments due to high‐peak currents of EV charging. Rising numbers of grid connected EVs is a challenging task in the future electricity grid planning. Thus an accurate EV charging system model is essential for reliable analysis of EV deployment.
