About The Position

Do you have what it takes to make smart vehicles for a smart world? Join the Ford Product Development team. Utilizing Design Thinking and User Experience methods, you will work to deliver breakthrough products and services that delight our customers. We are seeking forward-thinking, laser-focused professionals with a passion for bringing innovative, exciting, and sustainable ideas to life. We have opportunities around the world for you to contribute to such advancements as autonomy, electrification, smart mobility technologies and more! We are the movers of the world and the makers of the future. We get up every day, roll up our sleeves and build a better world -- together. At Ford, we're all a part of something bigger than ourselves. Are you ready to change the way the world moves? The batteries in electrified propulsion systems rely heavily on their thermal management system to maintain battery cell temperatures for performance and durability. Effective thermal management requires a challenging battery internal thermal system (BITS) design with many complex multi-system interactions both internal and external to the battery. Interacting systems include but are not limited to cells, arrays, high voltage EDS, cell vent management, battery controls, battery structures, powertrain cooling, heat management, and climate control. Managing this complex suite of interactions to provide the best overall thermal system design with the best balance between cost, performance, and durability is necessary for Ford to be competitive in the very challenging xEV marketplace. Complex interactions with heat management and powertrain cooling systems external to the battery are critical to providing needed cooling (and heating) of the battery to provide a battery external environment which will allow for needed durability. These critical interactions at the system level require clear ownership and management. Internal to the battery, interactions between the various hardware elements needing thermal management, the battery structure, the cell vent management system, the battery controls system and the BITS also require clear ownership and management. Guidance for CAE teams running crucial thermal analyses from the battery thermal team is also a key enabler to success in our enterprise. Deep technical understanding is necessary regarding the systems involved, how they interact, how they are controlled, and how they must evolve going forward for Ford to be competitive. Battery thermal system design has experienced significant and rapid evolution and is projected to continue at this pace in the foreseeable future. The development of temperature transfer or inference functions is a key technology that Ford has a strong need to advance significantly. Inference functions require enhanced coordination between different activities or systems but may allow for hardware flexibility or lower costs. Immersion cooling and the use of low-cost direct refrigerant-based cell cooling systems are other areas for technical growth. A technical expert position to lead HV battery system thermal management interactions, controls, analyses, and future development is critical to delivering Ford's electrification future at the right value.
