HEL has developed a custom battery testing calorimeter (BTC) based on the industry-standard Arc calorimeter developed by Dow Chemicals more than 30 years ago.
The custom BTC is a large-scale version of HEL's Phi-Tec adiabatic calorimeter.
Compact but robust, with a range of hardware- and software-based safety features, the BTC is fully software controlled and can be wheeled in and out of test locations easily and quickly.
Its advanced features enable the user to understand what may happen during a worst-case scenario arising from poor operation.
Specifically, the BTC can provide information such as exotherm 'onset' temperature, heat release (or temperature rise), pressure increase, global reaction kinetics, time-to-maximum rate (TMR) and SADT (commonly used in storage/transportation studies).
It is designed to test a range of battery types sized up to 35cm x 35cm.
Performance while charging under different conditions, as well as physical damage, can be simulated, allowing for the development of safer batteries with carefully determined operating limits.
