With nearly 700 channels available to test everything from watch-sized batteries to full-sized vehicle battery packs, it is no surprise that BTC serves as a Department of Energy core capability for independent, third-party battery testing.
At any given time, several hundred channels are in use. Researchers at BTC work closely with various groups within industry, including automotive manufactures and manufacturers of electric vehicles batteries. These companies send batteries at various stages of development to BTC to ensure consistent results. Testing for research and development products typically lasts for shorter intervals (i.e., only a couple of years), while some of the more established battery designs may have tests running for a decade or longer.
