EV+ Accelerating Rate Calorimeter

EV+ Accelerating Rate Calorimeter

Designed for EV cells and small modules and to fulfil requirements of US ABC & Freedom Car, SAND-2005-3123; SAE J2464 and other National and International prescribed tests

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+ 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.

Standard Features of the EV+ calorimeter are:-

  • Integrated cables for current and voltage measurement
  • Video camera
  • Gas collection line
  • Ability for battery pressure and temperature measurement
  • Ability for purging, evaluation, inerting
