Description
The rapid growth of e-bikes and e-scooters is straining conventional, fossil-fuel-intensive power grids and exposing a critical gap in urban charging infrastructure. In this work, a fully modular hybrid station that synergistically couples three energy vectorsphotovoltaics, second-life Li-ion battery packs, and the utility gridvia an intelligent, sub-50 ms source-arbitration network. The power-conditioning front end employs a flyback-derived SMPS delivering five tightly regulated outputs (5 V, 12 V, 37 V, 48 V DC; 230 V AC) at 9295% efficiency, while a bidirectional synchronous boost stage attains 9497% efficiency and future-proofs the system for vehicle-to-grid operation. End-to-end power quality is preserved with < 5% total harmonic distortion under dynamic loads. An ESP32-centric IoT stack with LoRaWAN back-haul furnishes kilometre-scale telemetry, secure billing, and over-the-air firmware updates, whereas a BiLSTM-assisted battery-management layer enables real-time state-of-charge and state-of-health tracking of repurposed EV modulesextending their usable life and anchoring circular-economy objectives. By fusing high-efficiency power conversion, adaptive energy-source orchestration, and cloud-native intelligence in a compact footprint, the proposed platform sets a scalable blueprint for low-carbon, resilient charging ecosystems that can keep pace with the next wave of urban micro-mobility. 2025 IEEE.
