CAEBAT: Computer-Aided Engineering for Electric-Drive Vehicle Batteries


NREL's work on the U.S. Department of Energy Computer-Aided Engineering for Electric-Drive Vehicle Batteries (CAEBAT) project is accelerating the development and lowering the cost of high-performance lithium-ion (Li-ion) batteries for next-generation electric-drive vehicles (EDVs).

CAEBAT engineering tools are helping battery designers, developers, and manufacturers create the advanced battery technologies needed to boost EDV performance and consumer appeal and ultimately reduce petroleum consumption and emissions. NREL has collaborated with industry, university, and laboratory partners to develop these breakthroughs in computer-aided engineering across three phases of the CAEBAT project.

NREL's CAEBAT work has been divided into three phases: CAEBAT-1, CAEBAT-2, and CAEBAT-3. For CAEBAT-1, three teams created software tools for battery pack design, some of which were based on NREL's multi-scale multi-domain (MSMD) model. Under CAEBAT-2, the teams worked to optimize MSMD speed and explored the use of CAEBAT to improve battery safety. Now underway, CAEBAT-3 activities focus on software integration and microstructure applications.
