To implement tests with larger batteries THT have developed the EVx ARC
The EVx calorimeter is necessary for larger batteries, modules and small packs, power tools, satellite, military and associated applications. The EVx calorimeter is rugged and is sited in a secure containment vessel.
Within the containment vessel the standard ARC calorimeter (as in ES-ARC) can be used and this is regularly supplied for "Double Systems". Such a system gives versatility capable of measuring:- small prismatic, coin cell, 18650 and other larger batteries used in power applications.
With the EVx system all safety tests can be carried out as well as Battery Performance studies.
