Home Battery Control

UX Research project for greenely

Context & Objective

Greenely, a digital electricity company, planned to launch their first home battery control feature in their app. The challenge was to ensure the feature was intuitive, useful, and trustworthy before releasing the Minimum Lovable Product (MLP).

My Role

I worked as the UX Researcher, responsible for:

  • Designing the research plan and test script
  • Recruiting and screening six representative participants
  • Moderating interviews and usability tests
  • Synthesizing findings through affinity mapping
  • Presenting prioritized recommendations to Product and Design

(Collaborators: Lee Georges – Notes & Design, Pierre Fosto – Product Management)

Method

Research focused on three guiding questions:

  1. Can users understand and configure battery controls without guidance?
  2. Does the interface feel intuitive to non-technical users?
  3. Are labels and translations clear in a real user context?

I conducted six semi-structured interviews and usability tests, collecting both behavioral observations and direct quotes to inform actionable improvements.

Insights

Key Findings

1. “I don’t know when the battery will finish charging

2. “I want to be able to start charging in the middle of the night when prices are the lowest”

3. “I would like greenely to provide the best optimization for battery health”

4. “I want to be able to start charging in the middle of the night when prices are the lowest”

Outcome & Impact

The product team integrated several recommendations into the next sprint—particularly scheduling, state-of-charge display, and time-remaining indicators. Stakeholders estimated a 25 % reduction in setup time and anticipated fewer customer support tickets around “when will it finish charging?”.

Reflection

This project strengthened my skills in:

  • Advocating for user-centered design in an emerging energy-tech domain
  • Rapid validation of high-impact features using lean research
  • Cross-functional collaboration with product managers and designers
