Bret Trimmer

Bret A. Trimmer, BSChE, MBA, is passionate about making battery packs smaller, lighter, and safer. He spent many years working with the leading maritime battery manufacturers to allow their systems to pass stringent European regulatory standards for thermal runaway. For the last several years, he has turned his attention to the EV, Drone, and Electric Airplane industries. He aims to increase the range per charge, allow faster charging, and prevent thermal runaway.

The first twenty years of his career were spent in the semiconductor and electronics industries, holding engineering, sales, and product management positions with Olin Microelectronics, FlipChip International, and Amkor Technologies. Bret joined NeoGraf Solutions in 2010, where he is currently the Applications Engineering Manager.

Efficient heat management is crucial for ensuring the optimal performance and reliability of these devices. This panel will explore the latest developments in Next-Generation Thermal Materials that play a pivotal role in enhancing heat dissipation and thermal conductivity. Experts from industry and academia will discuss innovative materials, fabrication techniques, and the challenges associated with implementing these materials in various applications. Join us to gain insights into how thermal interface materials can address the thermal management needs of emerging technologies such as high-performance computing, 5G, electric vehicles, and more.

Faster EV Charging, Extended Range, and Propagation Prevention through Advanced Thermal Management

Electric Vehicle, ePlane, eVTOL, and Maritime OEMs have several similar goals relating to battery thermal management. This presentation addresses the current significant topics.

With the first generations of EVs, the primary goal was to quickly get a car on the road that met the basic consumer needs in terms of reliability and performance. With the next generation of EVs, the OEMs are looking for optimized vehicles in terms of weight/driving range, cell-cycle lifetime, and safety (up to and including cell-to-cell propagation control). Battery pack manufacturers now use four primary strategies to prevent Thermal Runaway. All four will be discussed along with the impact of each on fast charging, cell performance, and cell lifetime. As a thin and lightweight thermal management material, flexible graphite heat spreaders are used to improve charging rate, cell cycle lifetime, driving range, and establish propagation prevention in both pouch and prismatic cell battery packs, while making the packs smaller and lighter. Five factors control how fast an EV can be charged. Only one of them can be easily controlled and all will be discussed.
