EV-ARC Accelerating Rate Calorimeter

ARC는 단열환경(Adiabatic condition)에서 대소형 배터리의 열안정성을 측정하기 위해 고안된 ARC로써  자동화된 Heat-Wait-Seek 작동 원리로 exothermic onset을 정확하게 측정하는 가속속도열량계 입니다.

 0.005 °C의 감도로 압력변화 및 전압, 전류변화를 동시에 측정하는  전세계 유일의 ARC입니다.

Features

The EV calorimeter is necessary for larger batteries, modules and small packs, power tools, satellite, military and associated applications. The EV calorimeter is used when variation of heat release over surface area (MultiPoint measurement) is to measured and associated thermal management applications. The EV 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 EV system all safety tests can be carried out as well as Battery Performance studies.

The BPC Battery Performance Calorimeter is an even larger calorimeter where thermal management is to be studied - it is not suitable for safety tests, but is used for multipoint and power discharge application and experimentation over environmental temperatures. It is restricted to 200°C.

Spares

A full range of spares and consumables are available. Any user requiring more information please complete the request form.

Low containers Designed by THT these low  containers are designed to enable accelerating rate calorimeter users to bridge the gap into the world of low-phi testing. These cells are available with several different fittings and can also be fitted with magnetic stir bars. Currently these containers are offered in stainless steel although other materials can be produced. Contact us for further details.

Burst Disk Unit THT has designed this burst disk assembly, which is suitable for any

accelerating rate calorimeter. Designed to sit above the calorimeter, this device enables the user to protect the system from cell ruptures. The user can fit a number of special burst disks which are designed to rupture at specific pressures and will cause the cell to rapidly discharge. Any liquid vented will be contained within the catch pot. This system is ideally used alongside low-phi containers and glass bombs

Battery sample holders THT manufactures holders for specific batteries to enable testing in both open and closed (with pressure connections) modes. THT are able to manufacture special holders for any battery dependent on a specified minimum order. Please contact us with your specific requirements.

Sample Holders Specific holders for all battery types.

Safety 2 cubic meter containment vessel (Blast Box) to allow working space; 3mm reinforced Steel, Proximity Switch, Door bolt; Burst Disk Assembly. Automated Fume Extraction facility

Control Modes Adiabatic; Quasi-Isothermal, True Isothermal, Isoperibolic, RampDetection of Endotherms and Tracking of Exotherms

Sample Testing Service For larger battery cells the EV-ARC can be used. A testing service including abuse and electro-thermal dynamics is available.

Abuse type testing will determine heat output when battery is shorted, overcharged or over-discharged. Such tests are routinely carried out in the THT ARC using the BSU option.

Testing can also be carried out to determine Cp variation of heat release over surface area (multi-point) and aspects of thermal management.

The full range of tests that can be carried out with the EV-ARC plus battery test options allows all information on the safety, efficiency, lifetime of batteries and thermal consequences of their  performance to be determined.
