Intern, Battery Cell Controls Engineer, Summer 2026

Team Description:

The Battery Cell Performance Optimization team drives the understanding and advancement of Lucid’s cell technology through testing, modeling, validation, design, and analytical characterization. We develop fast-charge and power-capability control strategies informed by real-world data from Lucid’s expanding vehicle fleet to ensure that customer usage is accurately represented. Our work bridges experimental testing with physics-based modeling to uncover the fundamental mechanisms governing cell performance and degradation.

As an intern on this team, you will contribute to integrating real-time electrochemical and data-driven models into cell testing workflows — enabling live visibility into cell health and performance. Your work will directly influence how we validate and optimize next-generation battery systems for efficiency, longevity, and charging speed.

Role/Responsibilities:

As a summer intern on the Battery Cell Engineering team, you’ll work on the following:

Key Deliverables

• Support development and validation of battery performance and health‑estimation models.
• Build and test simulation environments used to evaluate battery control strategies.
• Implement models into real‑time testing workflows.
• Analyze differences between predicted and measured cell behavior to improve model accuracy.

Deliverable Details

• Integrate battery models and controls into a simulation framework for testing and verification.
• Prepare these models for use in real‑time or automated testing environments.
• Learn how battery state estimation works within a vehicle‑level or system‑level context.
• Validate models through structured tests on lithium‑ion cells.
• Gain hands‑on experience with simulation tools (e.g., MATLAB/Simulink) and develop test protocols that incorporate real‑time
