Colorado: Isothermal Battery Calorimeter Quantifies Heat Flow, Helps Make Safer, Longer-lasting Batteries

Project Overview
Positive Impact: Isothermal Battery Calorimeters (IBCs) help create safer, more efficient batteries. IBC receives 2013 R&D 100 Award.
Location: Colorado
Partners: NETZSCH, National Renewable Energy Laboratory.
EERE Investment: $750,000 over 3 years
Clean Energy Sector: Sustainable transportationPDF

Partnered with NETZSCH, the National Renewable Energy Laboratory (NREL) developed an Isothermal Battery Calorimeter (IBC) used to quantify heat flow in battery cells and modules. This specially-designed calorimeter can perform precise thermal measurements at new levels of accuracy and functionality. Precisely measuring heat generation helps optimize battery thermal management systems to extend battery life and improve safety at an affordable cost. Entry to the market for this technology couldn’t be timelier, as it follows a 70% year-over-year jump in plug-in electric vehicle sales. NREL and NETZSCH received a 2013 R&D 100 Award in recognition of the IBC technology, which will help auto manufacturers create safer, more efficient batteries.

The Vehicle Technologies Office (VTO) develops and deploys efficient and environmentally friendly highway transportation technologies that will enable America to use less petroleum. These technologies will provide Americans with greater freedom of mobility and energy security, while lowering costs and reducing impacts on the environment.
