Battery Management Systems (BMS) Algorithm Developer (Carmel, IN)

Aptiv is a global technology leader in developing safe, green, and connected solutions for the automotive industry. Our Vehicle Electrification Systems Division is focused on designing and delivering innovative electrification systems that enable our customers to build more efficient, reliable, and sustainable vehicles.

Our broad portfolio covers the full spectrum of architecture electrification solutions, delivering power from the grid to the systems that need it most. We follow the power.

We envision a world with zero emissions. Making the future of mobility greener is at the heart of our mission.

Your Role

As a Battery Management Systems (BMS) Algorithm Developer in the Vehicle Electrification Systems Division, you will be responsible for contributing to an algorithm roadmap, contributing with your own expertise and expanding to include journal publications, research labs, national labs, academia, and industry partnerships.

You will work collaboratively with cross-functional teams of engineers and designers to ensure the development and delivery of products that meet our customers' needs and exceed their expectations. In your daily job you will:

• Contribute to a portfolio of battery models and algorithms, such as open circuit voltage (OCV) prediction with hysteresis, state of charge (SOC) tracking with real-time error correction, capacity learning over life, estimation of internal cell temperature and thermal gradients, internal resistance estimation, frequency-dependent impedance estimation, lifetime prediction, and state of health (SOH) reporting.
• Interface to customers and understand the usage scenario, load cycle, conditions, and performance envelope expected from the battery management models and algorithms.
• Interface to the battery manufacturer to understand the properties, limitations, and capabilities of the battery chemistry. Understand the data available from the manufacturer and what data is needed to fill in the gaps.
• Supervise experiments to test and validate each algorithm subcomponent using the battery laboratory with growth possibilities as the program progresses from cell-level to full-size electric vehicle battery pack systems.
• Maintain relationships with outside battery testing laboratories for tests not suitable for the internal battery laboratory.

Your Background

Key ingredients for succeeding in this role are your:

• Bachelor’s Degree in Engineering, computer science or equivalent technical field from an accredited institution.
• A deep interest and/or domain expertise in lithium-ion battery technology, chemistry variants, electrode and cell fabrication methods, and methods to model their performance and behavior.
