Job Description

DRIVE AN ACCELERATION TOWARDS ZERO EMISSIONS IN TRANSPORTATION THROUGH BETTER POWER ELECTRONICS.

We have an exciting opportunity for a Battery Management Systems (BMS) Algorithm Developer that will be located in Carmel, IN.

Responsibilities:

• Contribute to an algorithm roadmap, contributing with your own expertise and expanding to include journal publications, research labs, national labs, academia, and industry partnerships.
• Create and foster relationships with university research groups and government laboratories to obtain the latest research and implementations of battery models and algorithms.
• 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.
• Have expertise in contactor control, thermal management, diagnostic, fault scenarios, and cell balancing, based on the customer and battery type.
• Work with BMS firmware engineer and lab testing engineer to design lab test method 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.

Candidate Profile

Ideally you have an advanced degree (M.S. or Ph.D.) applicable to understanding and modeling battery performance. Expertise in understanding lithium-ion batteries, advanced testing methods, data analysis, algorithm modeling, and working with academia and university professors are critical elements for success.

This experience combined with a track record of relevant technical innovation, curiosity, communication, structured analytical thinking, sound business judgment and true leadership skills would make you successful in this role.
