Application Note: Battery Safety Data
BATTERY SAFETY DATA DIRECT FROM MANUFACTURER: Safety of batteries under different temperature conditions needs to be verified experimentally and "adiabatic" calorimetry is the widely accepted method. Data collected recently by MGL in China from one of their prototypes shows how under adiabatic conditions, the temperature at which a battery starts to undergo self-heating is detected and this provides the maximum safe temperature under which it can ideally be used. In addition, the calorimeter allows the battery to continue thermal runaway and hence provides direct information about the extent of the hazard.
Application Note: Video battery Testing
The performance demands on modern batteries subject them to considerable physical stresses. HEL supply a range of battery testing systems and now include Remote Video Monitoring to record deformation, smoking and degradation in real-time...
Presentation: Battery Safety Testing - Nov 2010, Beijing
A presentation made by Dr J Singh at the 5th International Forum on Li-ion Battery Technology, Beijing, China, Nov 2010, about HEL's advanced Battery Testing Calorimeter (BTC) as a unique solution for both small scale testing of battery components as well as direct simulation of larger scale battery incidents, including the "abuse" testing methods specified by various codes.
