Job description

JD: Battery Sox/State Estimation Algorithm Engineer

The main responsibility of this service is to provide engineering support to develop (or manage) and execute technical aspects of the Battery Algorithm, Performance, System design and engineering support areas and general expectations are listed below.

Responsibilities:

• Process and analyze battery data such as battery/cell performance data, drive cycle testing, capacity/energy tests, cell characterization tests (HPPC, OCV), and battery state estimation SOx validation for state-charge (SOC), state-of-power (SOP) limits, and battery state of health (SOH) estimation.
• Support data regression, statistical analysis, and parameter fitting functions related to battery/cell data, voltage/temperature response modes, and age modelling.
• Perform target deep-dive analysis of (historical) battery data to support root-cause analysis of battery state estimation-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 various test labs for characterization and validation testing activities.
• Provide as-needed battery data analysis/processing/simulations to support production program design release activities.
• Process SOx Validation data from Model-in-the-loop (MIL), Hardware-in-Loop (HIL), and Pack and Vehicle level testing.
• Perform as-needed data collection activities using software tools such as CANalyzer, INCA, and Matlab.

Basic Qualifications & Technical Skills

• Bachelor's in Electrical/Computer/Software Engineering or Computer Science
• with a minimum of 4+ years of relevant experience
• Two years of experience in data analysis/processing/mining
• Knowledge of parameter fitting, optimization, and data regression methods
• Working knowledge of Battery Management Systems
• 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 Requirements:

• Prior experience with 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
• Prior experience with battery/cell lab test equipment and xEV vehicle testing and DVP&R procedures.
• Knowledge of battery algorithms such as estimation of State-Of-Charge, State-Of-Health (resistance/capacity), and State-Of-Power availability.
