Introduction
The document introduces the Isothermal Battery Calorimeter (IBC), a range of systems designed to quantify heat release and battery performance across various battery types, including Coin Cell, 18650, 26650, 21700, Prismatics, Modules, and Complete devices. The IBC is crucial for studying battery stability, performance, efficiency, and life cycle by characterizing heat during charging and discharging due to internal impedance.

Isothermal Battery Calorimeter Variants
The IBC is available in several variants to accommodate different battery sizes:

• IBC Cylindrical: Suitable for single chamber up to 26650 with inserts for 21700 and 18650. It operates within a temperature range of -5°C to 60°C and a dynamic range of 200µW to 10W.
• IBC-CC Coin Cell: Features sample and reference chambers up to 2032, with a temperature range of -5°C to 60°C and a dynamic range up to 500mW.
• IBC-PL Large Prismatic: Accommodates battery sizes up to 300 x 300 x 40mm, with a temperature range of -30°C to 60°C and a dynamic range of 200mW to 100W.
• IBC-Air: Designed for electronic components with a chamber size of 450 x 400 x 300mm, operating within a temperature range of -20°C to 60°C and a dynamic range of 500mW to 100W.
