BPC는 EV와 같은 대형셀과 모듈을 연구하는 데 쓰이도록 개발되어, 충방전 시 열적 변화 특성 (특히 비열)을 정량화할 수 있습니다.

The BPC is not appropriate for stability, safety and abuse studies where battery disintegration is possible. The BPC has an upper temperature limit of 200°C but operates down to -30°C. Cryogenic operation is possible by linking to a refrigerated circulating bath.
A key and unique feature of the BPC is the ‘Thermal Diode’ heating system that allows current flow through the calorimeter. This eliminates need for conductive leads or cables to carry current. At high power operation such loads do come major heat loss and data error in calorimeters with no ‘thermal guard’. (The EV+ uniquely does have thermally guarded leads and these do minimise error)
The calorimeter has a depth of 50cm but its cross section is oval (50-65cm) maximising useful volume for large batteries.
With heat detection sensitivity at 0.005°C/min the BPC has stable specific detection for heat release. In conjunction with the THT surface area (multipoint) heat measurement option, the BPC at well below 1 w/g detection, is ideally suited for gaining information appropriate for Thermal Management.
The BPC used with THT ARC software and electronics can be used within the adiabatic isothermal or isoperibolic modes. The choice of mode relates to the studies undertaken.
Key options used with the BPC are the surface area (multipoint) option and the heat capacity option. The BPC complements the other calorimeters available from THT.
