To address issues like lack of actual electric vehicle (EV) charging load data, significant regional differences, and complex simulation methods, we propose an EV behavior simulation method consisting of trip chains, energy consumption chains, and charging chains. Initially, to tackle the scarcity of charging data, we derive a vehicle trip chain construction method using a data-driven approach, leveraging similarities between EV and conventional vehicle trips to understand EV travel patterns. Subsequently, we summarize energy consumption models, creating energy consumption chains based on trip chains. Lastly, considering factors like charging anxiety, queueing, and charging time, we develop the EV charging chain. Simulations of common charging strategies demonstrate their impact on user charging costs and the power grid.
