HEL (www.hazards.co ) provides hazard testing and consulting tools relating to Li-ion and other high performance batteries and storage devices. This includes adiabatic (ARC-type) calorimeters for thermal runaway testing which provides a direct measure of maximum temperature, maximum current and voltage limits relating to thermal explosion risk.
HEL has also developed an isothermal calorimetry technique, which allows heat generation rate under controlled conditions which provides both data for thermal management and helps to understand battery performance.
