The Battery Data Analysis Engineer works with the energy storage team to support battery testing, validation, and development activities related to the family of next-generation xEV FCA powertrains and batteries. The candidate will take a leading role in analyzing, mining, processing, and tracking the increasing amount of battery and cell test data generated 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. cell level, pack-level, vehicle-level, and fleet-level. The ideal candidate is expected to be highly analytical, and have experience in data analysis/processing.

Job responsibilities include but not limited to:

  • Process and analyze battery data such as battery/cell performance data, drive cycle testing, cell characterization tests (HPPC, OCV), usage history statistics, battery management system (BMS) functions, battery state estimation SOX validation for state-charge (SOC), state-of-power (SOP) limits, and battery state of health (SOH) estimation

  • Develop core software histograms requirements for collecting the battery and cell characteristics

  • Support data regression, statistical analysis, and parameter fitting functions related to battery/cell data, voltage/temperature response modes, and age empirical modeling

  • Perform target deep-dive analysis of FCA (historical) battery data to support root-cause analysis of battery related issues

  • Deliver reports to department engineers on battery test and analysis activities

  • Generate automated graphical test reports to support validation, analysis, and verification of battery software functions such as battery state estimation, cell balancing, and sensor measurement processing

  • Coordinate with FCA/supplier battery/cell/HIL test labs for characterization and validation testing activities

  • Provide as needed battery data analysis/processing to support production program design release activities

  • Perform as needed data collection activities using software tools such as CANalyzer, INCA, and Control Tec

  • Interface with supplier/FCA cell/battery specialists to optimize battery data generation, collection, and analysis workflow

  • Support development of appropriate battery usage history statistics and their online recording

  • Constructively contribute to research and development activities related to battery/cell modeling and testing for automotive applications

Basic Qualifications:

  • Bachelor of Science in Electrical, Computer or Software Engineering or Computer Science from an accredited university

  • Minimum 5 years of relevant experience

  • Minimum 2 years of experience in data analysis/processing/mining or an advance degree

  • Knowledge of parameter fitting, optimization, and data regression methods

  • Excellent MATLAB scripting skills or other languages e.g. Octave, Python

  • Effective graphical presentation, interpersonal, and time management skills to engage development and testing teams/personnel

Preferred Qualifications:

  • Masters of Applied Science in Electrical, Control, Chemical, Mechanical, Computer or Software Engineering or a Masters in Computer Science, or related discipline with Battery Management System experience at an accredited university

  • Working knowledge of battery management systems mechatronics and software functions, battery/cell modeling and characterization methods

  • General knowledge of xEV vehicle and powertrains

  • Expertise in statistical analysis, signal processing, simulations, regression, optimization, machine learning, big data analysis

  • Experience with battery/cell lab test equipment and xEV vehicle testing and DVP&R procedures

  • Research and development experience to creatively support innovation projects and university research collaborations
