| dc.description.abstract | This report presents the design and implementation of a low-cost, bidirectional Vehicleto-House (V2H) energy management and charging system, developed as a final year project prototype at Busitema University. The system was built around an ESP32-S3 micro controller, IR2104 MOSFET gate drivers, IRF3205 power MOSFETS forming an H-bridge converter, an ACS712 current sensor, and a 12 V, 7 Ah sealed lead-acid (SLA) battery as the energy storage unit. The primary motivation for this project is Uganda's persistent power-supply unreliability, rising electricity costs, and the growing adoption of electric motorcycles without corresponding bidirectional charging capabilities. Existing Vehicle-to-Grid (V2G) and V2H commercial systems are designed for high-capacity electric cars in developed economies and are inaccessible in the Ugandan context. This project addresses that gap by demonstrating, at low voltage and laboratory scale, that bidirectional energy transfer from a motorcycle-scale battery to a household load is technically feasible using locally sourced components. The implemented system demonstrated successful directional control of DC energy flow, with the ESP32-S3 firmware providing PWM-based switching of the H-bridge converter at a frequency of 20 kHz. The ACS712 sensor enabled real-time current monitoring for both charging and discharging modes. Voltage regulation and modeswitching logic were validated under resistive loads representative of small household appliances. | |
