Overview

Battery  Safety Testing Calorimeter - Phi-TEC BTC

Overview

HEL's phi-tec range of adiabatic calorimeters has been expanded to include the "Battery Testing Calorimeter" or BTC. The operating principles are the same as a standard "ARC" system which is already proven in phi-tec designs. The importance of EV and other high energy battery applications warrants a separate design.

One of the key reasons for a change in the design is the size and shape of cells and battery packs that need to be tested. Traditional adiabatic calorimeters can handle the smaller cells, typically up to 18650 cells but not larger. The custom calorimeter allows for high energy and larger cells to be tested, defining as standard the maximy safe temperature but also extension to include for multiple charge and discharge cycle tests which allow discharge (current) rate limits and overcharge (voltage) limits to be defined.

One system for all tests...

The BTC is in fact very versatile due to proprietary adiabatic control model used in the control and this allows accurate results are produced for small battery components, 18650 batteries and much larger batteries and battery packs, including EV, HEV, Military and commercial air craft
