Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking this could be related to recent software updates. Have there been any significant over-the-air updates in the last quarter?

Why it matters: Software changes can significantly impact battery management systems. Expected answer: Yes, there was a major update to improve charging speed. Impact on approach: If confirmed, we'd focus on software-related hypotheses.

• Considering potential hardware issues, has there been any change in battery suppliers or manufacturing processes recently?

Why it matters: Changes in components or processes could affect battery performance. Expected answer: No changes in suppliers, but a new manufacturing line was introduced. Impact on approach: We'd investigate the new manufacturing process for potential issues.

• Given the specific 15% decrease, I'm curious about the consistency of this drop. Is this decrease uniform across all vehicle models and regions?

Why it matters: Uniform decrease suggests a systemic issue, while variations could point to specific factors. Expected answer: The decrease is more pronounced in newer models and colder regions. Impact on approach: We'd focus on model-specific features and environmental factors.

• Thinking about user behavior, have there been any significant changes in how customers are using their vehicles compared to previous quarters?

Why it matters: Changes in usage patterns could affect perceived battery range. Expected answer: Data shows an increase in fast charging usage. Impact on approach: We'd investigate the impact of frequent fast charging on battery health.
