This paper presents a protected low-voltage Vehicle-to-Grid energy-management platform that combines an ESP32 controller, an 18650 lithium-ion battery pack, a current-limited bidirectional DC-DC converter and a PC-based optimization application. The ESP32 acquires battery voltage, bidirectional current, temperature and DC-bus demand, estimates State of Charge and enforces local safety limits. Framed UART communication transfers telemetry to the PC and returns a bounded CHARGE, DISCHARGE or IDLE request with a sequence number, current limit, timeout and checksum. A short-term load forecast supplies the optimizer, which seeks to reduce peak demand and unnecessary cycling while respecting energy, current, temperature and availability constraints. The proposed validation compares optimized operation with immediate charging using forecast error, peak-demand reduction, energy shifted, command latency, packet-error rate and safety interventions. The platform supports repeatable laboratory study without cloud services or direct utility-grid connection.
KEYWORDS
The proposed V2G platform integrates protected battery sensing, ESP32-based local control, framed serial communication, short-term load forecasting and constrained energy optimization. Its main contribution is an auditable division of responsibility: the PC recommends an operating action, while the embedded controller decides whether the action is safe to execute. The design supports repeatable comparison of forecasting and scheduling methods without depending on cloud services or direct utility-grid connection. Future work will complete calibrated hardware trials, compare forecasting models on unseen profiles, investigate probabilistic forecasts and model predictive control, and evaluate migration to CAN, Modbus or vehicle-charging protocols. Any hardware scale-up will retain independent protection and require new insulation, thermal and certification analysis.
