Climate-resilient electric vehicle charging infrastructure for sustainable cities: An interpretable causal-ensemble framework for preventive maintenance and low-carbon mobility
Summary
The FGDSE (feature-governed dynamic stacking ensemble) framework is introduced to predict fault risk in electric vehicle (EV) charging infrastructure, enabling preventive maintenance against urban climate stress like extreme heat and heavy precipitation. This interpretable decision-support system partitions heterogeneous signals into four feature families for domain experts and adds two deep temporal experts for short-term and long-term degradation. A horizon-wise gating mechanism forecasts daily fault risk over 1 to 30 days. Evaluated on 25 months of data from 13 stations, FGDSE surpasses twelve baselines beyond the ten-day horizon, maintaining approximately 85% macro-recall at 30 days with an AUC decay of only 3.2 points. It reveals extreme heat as the sole exposure whose causal effect amplifies over time, flagging roughly 30% of posts as heat-sensitive and providing quantitative thresholds for climate-adaptive maintenance.
Key takeaway
For MLOps Engineers or urban planners managing EV charging infrastructure, this framework offers a critical shift towards climate-resilient operations. You should integrate predictive models like FGDSE to move beyond reactive repairs, especially considering extreme heat's amplifying causal effect on fault risk. Utilize the identified quantitative thresholds to implement proactive, climate-adaptive maintenance strategies, ensuring sustained low-carbon mobility and urban energy resilience.
Key insights
FGDSE predicts EV charging fault risk using a causal-ensemble framework, enabling climate-resilient preventive maintenance.
Principles
- Heterogeneous signals require specialized expert models.
- Causal analysis reveals amplifying climate stress effects.
- Ensemble learning improves multi-horizon fault prediction.
Method
FGDSE partitions signals, assigns them to domain and deep temporal experts, then uses a horizon-wise gating mechanism for adaptive weighting to forecast daily fault risk over 1-30 days. SHAP and X-learner provide causal decision support.
In practice
- Identify heat-sensitive EV charging posts for targeted maintenance.
- Implement climate-adaptive maintenance based on quantitative thresholds.
- Shift from reactive repair to proactive fault prevention.
