 Week 8 Blog – Technology Research & Early Technical Foundations

This week my main focus was on deepening the technology research for VehicleGrid and refining the core technical direction of the system. I spent a significant amount of time analyzing the technological landscape around EV routing, charging infrastructure APIs, optimization algorithms, and geolocation services. This was important for validating whether our concept was technically feasible before we progress into design and implementation.

I examined the major algorithms used in EV routing, including A*, Dijkstra, reinforcement-learning approaches, and more advanced optimization methods used in recent studies. I also looked into how battery characteristics, environmental factors, and charger availability influence route calculations. This helped clarify the technical bottlenecks we may face later, especially around data accuracy and range-anxiety modeling.

On the integration side, I researched multiple API options beyond just Google Maps, including Open Charge Map, PubNub, and ArcGIS, to understand redundancy, reliability, and licensing constraints. I compared their data structures, authentication methods, usage limits, and whether they support live charger status. This is where the idea of incorporating multiple fallback APIs came from, which reduces dependency risk and gives us more freedom during development.

Overall, this week was about building the technological foundation needed for the rest of the project. By consolidating this research, I now have a clear understanding of our technical requirements, which APIs will support each function, and the constraints we need to keep in mind when designing the system architecture next.

 This week I suggested that we build a web-based application, since it would be easier to present and maintain . I also shared my screen to walk my team through serveral of my past project s, includes a Movie Review Web App , an Advanced Web Project , a Shooter Game and a Task/Calender App . These demonstrations highlight my technical ability acrosss both web and game development and based on this the team suggrested that I would be the most suitable choice to take on the role of main developer for the project. Beyond my project showcases, I also supported our collaboration setup by creating a Discord server so the team could share updates and stay connected outside formal meetings.

Tausif Rahman This week I presented the  Audit App  concept with its two parts:  Order Audit (OrderAuditPro)  and  Walkthrough Auditor . I later uploaded documentation and demonstration files of an Android version of the Order Audit module, which helped the team understand the concept more clearly. In addition, I encouraged the team to think about their  past subject projects  by asking what they had worked on in Android, iOS, cross-platform, and project management courses, to see if those experiences could be adapted into our current project. Alongside that, I shared several of my own past coursework projects, such as  ScholarSwap  (resource and book exchange platform),  SurvivAway  (a budgeting and life-flow helper), and  FocusFlow  (a study planner with ADHD-focused features). I also raised the issue of  legal risks  in some ideas, such as consumer liability in a Parking App or data security concerns in a Pass...

  participated in the voting process and initially leaned toward the Audit App, but after deeper discussions, I found the Customer Service Checker and Vehicle Manager ideas more scalable and innovative. I located an academic paper titled E-Charge, which described an EV-charging-station planning system using open data and efficiency modelling. I shared the paper with the group and led a discussion on how its methods could guide our approach—particularly its use of driver-collected data, efficiency mapping, and route-planning optimisation. I also helped analyse how to simplify our version for Trimester 1, keeping it practical while leaving room for AI integration later. Additionally, I began finding and reviewing more EV-planning research papers to contribute to our shared knowledge base.
