Sr. BMS Engineer - Algorithm

Supernal is at the forefront of creating emerging mobility solutions that will foster the development of human-centered cities. We are designing a completely new electric vertical take-off and landing (eVTOL) aircraft tailored to the mobility needs of future cities. This allows passengers a seamless intermodal journey that safely transports them to their final destination. We fuse research in autonomy, robotics, aviation and services to define a new category of mobility for the world’s communities. We believe in creative thinking and collaboration to help build a better mobility experience for everyone, improving people’s ability to move – whether for work or play.

The BMS Engineer - Algorithm focuses on research & development of Battery prediction algorithms for different cell chemistries used in our Energy Storage Systems (ESS). The role is responsible for developing algorithm requirements, research & development, and verification of algorithms after implementation in BMS. This role collaborates with other HW / SW / Cell Engineers in Battery team and other multi-functional team members to develop Algorithm requirements and to support integration testing at Powertrain, ESS system, or Cell module level.

• Requirements development for different performance prediction algorithms
• Research & Development of dynamic & high-fidelity battery cell models for use in system modeling, battery gauging & charging for high voltage battery packs
• R&D of algorithms to estimate available State of Energy (SOE) and dynamic State of Power (SOP) of battery pack based on system load profiles and prediction requirements using multiple techniques that give redundant and robust solutions
• Verification of models and algorithms developed using MIL, SIL, PIL and HIL techniques at battery pack level and support similar activities at system level (System in the Loop testing)
• Verification of model parameter tracking and prediction algorithm accuracies against HW and environmentally induced parameter variabilities using multi domain models (Thermal, electrical) at battery pack level
• Development of test strategies and harnesses for models and algorithms to eliminate issues early in the design phase
• Optimization of algorithm to work within real time computer resource constraints like CPU cycles, memory, and power consumption
• May require up to 10% of domestic and international travels
• Other duties as assigned
