NREL Computer-Aided Engineering for Electric Drive Vehicle Batteries (CAEBAT)

The Computer-Aided Engineering for Electric-Drive Vehicle Batteries (CAEBAT) project aims to accelerate the development and lower the cost of lithium-ion batteries for next-generation electric-drive vehicles (EDVs).

Project goals include:

  • Developing engineering tools to design cells and battery packs
  • Shortening the battery prototyping and manufacturing processes
  • Improving overall battery performance, safety, and lifespan
  • Reducing battery costs.

NREL brings its predictive computer simulation of lithium-ion batteries, known as the Multi-Scale Multi-Dimensional (MSMD) model framework, to the CAEBAT project. MSMD's modular, flexible architecture connects the physics of battery charge/discharge processes, thermal control, safety, and reliability in a computationally efficient manner. This allows independent development of submodels at the cell and pack levels.

NREL coordinates the CAEBAT project for the Vehicle Technologies Office of the U.S. Department of Energy's Office of Energy Efficiency & Renewable Energy.

Industry Teams

After a competitive selection process, NREL awarded subcontracts worth $7 million to the following three industry teams:

Each team is working independently to develop and validate modeling and design tools for EDV batteries, with an emphasis on integrating electrochemical, electrical, mechanical, and thermal physics. Teams are also exploring different chemistries, cell geometries, and battery pack configurations.

These industry partners are contributing 50% of project costs, bringing the overall budget to $14 million for three years.

In support of the CAEBAT project, Oak Ridge National Laboratory (ORNL) is developing an open-architecture software interface to link the models developed by different teams into the CAEBAT suite of tools. ORNL is also developing input-output interfaces to allow utilization of models across different platforms.


NREL's Publications Database offers a wide variety of documents related to the development of batteries and energy storage systems for EDVs. The following publications document CAEBAT project activities:
