GM Energy Ultium Home

The Challenge

As the world shifts toward electrification, GM has an opportunity to lead in home energy. With a suite of solutions, including vehicle-integrated backup power, standalone battery systems, and solar-compatible options, GM can deliver energy independence, outage protection, and long-term savings. To support this vision, our team was tasked with designing and building an e-commerce portal that allows customers to explore, configure, and purchase these energy products with ease.

The Process

Research & Analysis: We conducted user interviews, surveys, and analyzed in-app analytics to understand the pain points and user needs. We also studied competitor apps and industry trends to gather insights.

Information Architecture: Based on the research findings, we structured the app's navigation and content, prioritizing features and information according to user needs.

Wireframing & Prototyping: We designed low-fidelity wireframes to visualize the new layout and navigation, iteratively refining them based on user feedback. Afterward, we built a high-fidelity, interactive prototype to test the design.

Usability Testing: We conducted usability tests with a diverse group of users to validate the design and identify areas for improvement. Based on the feedback, we made a few adjustments to the design.

Visual Design & Style Guide: We developed a cohesive visual language, including color schemes, typography, and iconography, ensuring consistency throughout the app. We also created a style guide to maintain design consistency in future updates.

The Results

The new e-commerce portal launched successfully, enabling users to seamlessly explore and purchase GM’s home energy products. Within the first 3 months:

  • Customer inquiries related to product confusion decreased significantly.

  • Internal stakeholders reported increased sales confidence and a stronger brand perception in the energy space.
