IBC-PL

Isothermal Battery Calorimeter - PL

Cell format: Prismatic

Measure heat release under isothermal conditions during charge/discharge protocols. Designed for small prismatic cells

Isothermal Battery Calorimeter - PL

The IBC-PL provides accurate and easy testing of heat output from charging and discharging a single battery.

Heat occurring during the charging and discharging of batteries is largely due to their internal impedance. Characterisation of this heat at different operating temperatures is vital for efficient thermal mangement of cells in packs or modules.

Isothermal calorimeters have higher sensitivity than adiabatic calorimeters. Their temperature range is limited and they are not appropriate for safety abuse testing when battery disintegration or high temperatures may result.
