Battery Systems Data Analyst Engineer

JD: Battery Pack Data Analysis

The Battery Systems Data Engineer will be responsible for the development of battery data processing and analytics tools to support data input for design and development of xEV Battery Systems. The candidate will take a leading role in analyzing mining processing and tracking the increasing amount of battery test data generated from battery vehicle and fleet testing during the course of product development testing and validation. The candidate will be involved in multiple vehicle programs and deal with a broad range of data i.e. electrical mechanical battery & thermal data. The ideal candidate is expected to be highly motivated in developing intuitive data analysis/processing techniques. Some background in electrified powertrain vehicles is preferred.

Responsibilities include but not limited to:

Develop document the engineering requirements for automotive traction battery systems. Lead other engineers and teams across cell battery and vehicle level to balance requirements.

Support battery system engineers using data to develop battery usage profiles and mission profiles for battery life modeling/ prediction/simulations and component designs for durability and other applications.

Support battery system engineers using data to analyze battery and vehicle usage data from Fleet Test Vehicles to compare and validate battery life and performance models.

Analyze critical battery performance during the entire product lifecycle including power and energy performance battery life safety performance.

Help develop tests as needed for verifying battery system performance and execute product design improvements.

Lead the data analysis activities and interpretation related to battery field performance to guide requirements development and product improvements

Provide data analysis in investigation of system issues and support root cause analysis and mitigation and corrective action plans.

Deliver reports to department Engineers on battery test and analysis activities and generate automated graphical test reports
