µBC - micro Battery Calorimeter
Measure heat release under isothermal conditions during charge/discharge protocols. Designed for coin cells up to 30mm x 6mm.
The µBC provides accurate and easy testing of heat output from charging and discharging a single battery. The instrumnet is provided with an integrated cycler: 10V, 0.1mA-100mA.
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 that adiabatic calorimeters. Their temperature range is limited and they are not appropriate for safety abuse testing when battery disintegration or high temperatures may result.
