Abstract

This report focuses on the USB implementation subgroup of the Wrepair Powerstation Project, which aimed to design and develop a versatile USB powerstation capable of supporting both high-power delivery and data transfer through USB Type-C ports. The implementation involved integrating advanced charging protocols, real-time measurements, and power control capabilities into a modular system that can seamlessly fit into existing Wrepair stations. This integration enables the powerstation to feature dynamic power allocation and visualisation of charging performance.

Key tasks of this project included selecting appropriate power delivery integrated circuits (ICs), designing a high-speed USB data hub, and developing control hardware to manage power and data flow efficiently. The USB charging station is designed to support up to 100W per port, with a total available power budget of 300W, distributed across six USB Type-C ports. The powerstation also incorporates safety features to protect against overcurrent, overheating, and short circuits, ensuring user safety and device protection.

The report details the design process, including the selection of components, system integration, and validation procedures. The design process involved evaluating different power delivery systems, including development boards, PD modules, and stand-alone chips, to select the most suitable solution for the project requirements. The chosen solution, the IP2368 PD (Power delivery) module, was initially tested but was found to be inadequate, leading to the exploration of alternative modules such as the SW2303 and MAX25430 development boards.

Furthermore, the design includes a USB data hub sub-module to facilitate high-speed data transfer and connectivity. This hub supports multiple devices and allows for real-time data logging and display, enhancing user interaction and monitoring capabilities. The validation and evaluation phase involved rigorous testing of the USB implementation submodule, including power delivery, measuring and controlling capabilities, and overall system integration.

The results demonstrate that the USB implementation meets the required specifications, ensuring efficient power distribution and data handling for multiple devices. This work contributes to the overall Wrepair Powerstation Project by providing a robust and scalable USB solution that enhances the functionality and utility of Wrepair stations.
