.The data used in this study is drawn from a publicly available mobile application, which provides the real-time availability of charging piles (i.e., idle or not). Within Shenzhen, China, a total of 18,061 public charging piles are covered during the studied period from 19 June to 18 July 2022 (30 days) with a minimum interval of 5 minutes and 8640 timestamps
. As shown in Figure 1, the city is constructed into a graph-structure data with 247 nodes
(traffic zones) and 1006 edges
(adjacent relationships).
Figure 1. Spatial distribution of the 18,061 public EV charging piles in ST-EVCDP.
Besides, the pricing schemes for the studied charging piles are also collected. Among the 247 traffic zones, 57 of them (enclosed in red lines) deploy time-based pricing schemes, while others use fixed ones. More statistical details are illustrated in the following table.
Expanding on the foundation of ST-EVCDP, we have gathered an extensive dataset called ST-EVCDP-v2, specifically tailored for EV-related research. This dataset covers a timeframe of one year, spanning from September 2022 to September 2023, which includes comprehensive information such as coordinates, charging occupancy, duration, volume, and price for a total of 1,682 public charging stations with 24,798 public charging piles. Notably, it provides detailed information on charging stations, with a granularity that allows analysis at the charging station level. And its temporal interval is one hour. You can download the data from Google Drive Link.

We developed a physics-informed and attention-based approach for spatio-temporal EV charging demand prediction, named PAG. Expect that, some representative methods are included, e.g., LSTM, and GCN-LSTM, GAT-LSTM. You can train and test the proposed model through the following procedures:
main.py
or use the default model (PAG-) by skipping this procedure.main.py
via Pycharm, etc. or change your ROOT_PATH and command:cd [path] && python main.py
models.py
and replace the model in main.py
.More updates will be posed in the near future! Thank you for your interest.
