Rapid Growth in EV Ownership
The rapid growth in electric vehicle (EV) ownership marks a transformative shift in the automotive sector. As nations worldwide commit to electrification, governmental policies and market dynamics are crucial in accelerating this transition.
Technological Convergence
Technological convergence involves the fusion of diverse technologies into innovative systems that open up new realms of possibilities. As diverse technological systems and their applications increasingly intersect, they catalyze the creation of novel opportunities, driving smarter, more efficient solutions.

As nations worldwide commit to electrification, the dynamics within the automotive market are consequently evolving to accommodate an increasing demand for electrification. This includes not only increasing the number of charging stations but also improving their management systems to ensure that they are available to those who need them when they need them.
Now is the ideal time to leverage cutting-edge technology and unlock new possibilities to address the rising demand for electrification.

I used a combination of quantitative and qualitative research. I sent out questionnaires and I conducted hour-long interviews with both EV users and professionals working in the EV industry.
Primary Research
Problems
FOR EV OWNERS




"ICED" EV Spots
You want to charge your car, but all the EV spots are occupied, either by other electric vehicles or by internal combustion engine cars.
Out of Order Chargers
Research from Harvard Business School indicates that one in five public chargers in the US is out of order, and they often remain not repaired for extended periods.
Idle Fees
If drivers don't move their cars promptly, idle fees begin accruing 5 to 10 minutes after charging is complete.
Time Wasted
Concerned about idle fees, drivers often wait by their cars with their phones, leading to unnecessary time spent waiting.
FOR SYSTEM OPERATORS

Underutilized Chargers Lead to Profit Loss
The problems that users encountered not only frustrates drivers who need to recharge but also results in lost revenue for service providers who cannot utilize their charging stations efficiently.

Heavy Digging Involved During Installation
For businesses, installing traditional chargers often require extensive digging. This can block off multiple parking spots and disrupt regular operations.
How might we develop a scalable and well-designed EV charging solution that optimizes operational efficiency for system operators while enhances convenience for users?

Charging Methods
I explored various charging methods, such as drive-thru wireless charging, bot charging, drone charging etc. I evaluate each concept in aspects like viability, difficulty of implementation, and future development, and eventually chose bot charging at it scored the highest overall.

Battery Pack

To optimize costs and efficiency, the system separates the bot from the battery packs. The bot, equipped with its robotic arm, transports and connects battery packs to vehicles, reducing manufacturing expenses while expanding service coverage.
Bot: carry battery packs + plug and unplug
Battery pack: charge vehicles
Station: store and recharge battery packs

Beachhead Market
I explored various beachhead market options for launching this new charging service. Using tools like the Business Model Canvas and the Opportunity Attractiveness Scale, I evaluated each location and identified shopping centers as the ideal choice. This option scored highly overall and aligns well with consumers' charging habits.
Mood Board

Slender
The design is envisioned with a tall and slender form to ensure visibility and enable smooth navigation in tight parking conditions
Sturdy
Exposed engineering elements keep people aware of operational areas, while a sturdy overall stance conveys reliability and durability.
Sleek
A predominantly white color palette underscores the design’s sleek, modern aesthetic and reflects sunlight to reduce heat buildup in the battery packs.
Form Exploration
AI Brainstorming
I used MidJourney as a quick brainstorming tool and got some inspiration.




Scale Study
I built a scaled mock-up using cardboard boxes and tested it in parking lots. By recording videos, I analyzed whether it obstructed driveways or interfered with other drivers and pedestrians.
Exploration & Refinement
I used sketches to explore the overall form and experiment with various arrangements of key functions. I landed with a slender form to minimize obstruction in parking spaces while maintaining stability.



I started with Rhino to explore and visualize the overall form and robot arm placement. I then transitioned to SolidWorks for detailed refinements and precise dimensioning.






Iterations
3D-printed scaled models to refine the bot's stability. During the iteration process, I increased the width of the bot's base and gave it more robust-looking wheels to enhance its overall stability.

Station Layout
To address the issues of underutilization and the extensive digging faced by system operators, I aim to create a compact station design. This solution allows businesses to strategically choose locations closest to the grid for station installation, reducing disruption, conserving parking space, and simplifying installation.
I designed the station dimensions based on the standard size of U.S. parking spaces. Using plan drawings and Rhino models, I explored various station layout options.
