ARC EV+ Professional Battery Accelerating Rate Calorimeter

EV+ ARC Professional Battery accelerating rate calorimeter, battery runaway analysis

Stock Status: In Stock


The EV+ ARC Accelerating Calorimeter has been designed for EV cells and small modules and to make the needs of testing necessary with EV batteries.

Many prescribed ‘standard’ tests call for Calorimetry and also call for use of abuse testing (eg SAND, SAE).

Tests call for video monitoring, gas detection/analysis, nail penetration and crush under controlled conditions.

The EV+ calorimeter from THT has been designed to accommodate many of these tests - and more whilst gaining quality information on heat release.

The EV+ ARC is an cylindrical calorimeter 40cm in diameter and 44cm depth. Unlike other THT adiabatic calorimeters the lid seals to the base unit. This seal is restricted to below 1 bar and is maintained by electromagnets. This allows for inertion of the environment and the ability to collect products of battery disintegration. A gas collection line (leading to gas collection bag) is standard.
