Om jobbet
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.
What You Will Do
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
What We Are Looking For
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 vehicles (BEVs)
Exposure to second-life, residual value, or warranty risk analysis
Experience comparing BMS estimates with external models
Basic ability to work with Python, SQL, or similar tools
Background in high-utilization or commercial vehicle applications
Education
Degree in electrochemistry, battery technology, electrical engineering, materials science, or similar
Advanced studies within energy storage systems are a plus
Why Multiply
Work on real-world electrification challenges with direct impact on sustainability and lifecycle efficiency
Combine deep engineering knowledge with data-driven decision-making
Collaborate in cross-functional teams spanning software, data, and systems engineering
Contribute to building scalable capabilities for next-life battery use and optimization
