About this role
In this role, you will contribute to building next-generation capabilities for assessing battery health and lifetime, enabling smarter decisions across the lifecycle of electric vehicles—from first use to second-life applications.
You will work closely with experts in data science, software, and engineering, bringing critical domain knowledge to ensure that battery insights are technically sound, interpretable, and actionable.
Responsibilities
- Develop and validate methods for State of Health (SOH) and Remaining Useful Life (RUL) estimation for Li-ion batteries
- Analyze real-world vehicle and battery data to understand degradation behavior over time
- Interpret and explain battery aging based on factors such as:
- Temperature
- State of Charge (SOC)
- Depth of Discharge (DoD)
- Charging patterns and C-rate
- Load profiles and usage conditions
- Compare and evaluate on-board BMS health estimates vs. off-board analytical models
- Define confidence levels, limitations, and applicability of lifetime predictions
- Collaborate with cross-functional teams to ensure models are physically grounded and credible
- Translate battery health insights into practical recommendations for:
- Lifecycle planning
- Residual value and risk assessment
- Warranty and service strategies
- Second-life and reuse scenarios
Requirements
- Strong background in Li-ion battery technology and degradation mechanisms
- Experience with battery lifetime assessment, including:
- Calendar aging
- Cycle aging
- Real-world usage effects
- Deep understanding of:
- SOH and RUL
- Capacity fade and resistance increase
- Performance degradation in field conditions
- Experience working with battery data from vehicles, BMS systems, or testing environments
- Ability to critically evaluate models and challenge assumptions
- Experience collaborating with data scientists, engineers, and business stakeholders
- Strong communication skills—able to explain complex battery behavior clearly
- Meriting Experience
- Experience with battery systems in electric vehicl
