Battery Safety and Battery PerformanceStudiesWorld Benchmark Battery Testing Calorimetry
Now a complete range of calorimeters from THT tocover all needs for thermal measurement of largeformat cells or small modules… Adiabatic andIsothermal. The true ARC ™ technology * firstcommercialised in 1979 has been manufactured byTHT since the mid 1990’s and continues to this dayfor battery, chemical, explosive, oil and otherapplications with reactive materials. The ARCcalorimeter family is shown hereThe EV+ and BPC Calorimeters and all their optionsare now fully developed and available from THT.THT has implemented software for appropriate largepower cyclers to give turnkey systems. For theautomotive industry cyclers to 100V 200A have beenimplemented down to, for small batteries, 5V, 5A.First BPC and EV+ units have been shipped and arenow being used across three continents. The rapidadvancement of larger format Li cells for automotiveuse has led to need for these large calorimeters.Download our complete Battery Brochure.
ARC ™ is a trade name of Thermal Hazard Technology and Netzsch andcannot LEGALLY be used by other makers of calorimeters (battery, chemicalor other application)
Welcome to THT’s June newsletter of 2013, focusing on calorimetry for battery applications

June 2013 Newsletter
Testing of batteries and small modules….Customer needs have been met that includevideo monitoring and gas collection for onwardanalysis. This led to the need for a sealedcalorimeter with clear safety releasemechanisms. This has been addressed by use ofelectromagnets. The measurement of heatprofile over the cell surface has been addressedby up to 24 thermocouples monitoring thetemperature over the cell surface.
Most challenging and uniquely devised by THT isthe need for Nail Penetration at controlled ratewithin the sealed environment. THT offers avariety of controlled speed high torque units – upto 10cm/sec and 37kN
The LNFO - Liquid Nitrogen Flow Option allowssub zero testing to -50°C
7kVA – the EV+ power supply needs6000Watts... Why?The larger calorimeters still need robustness andthough not as thick as the standard ARCcalorimeter – there is a lot of metal to heat.There is the need to heat at rates to 20C/min.You cannot have it both ways – either use acalorimeter with too thin walls or apply morepower.
THT EV+ will track at up to 20C/min, not the2-3C/min from other calorimeters or poordesign.
DataYes we supply data:- Tracking andperformance of the calorimeter itself and ofthe options:- Nail penetration, multipoint,specific heat. Contact THT with your specificrequests.
Gas collection optionsFrom collection bags to closed cylinders,THT have a number of options, THT mayadvise, but the choice is down to the user
User base continues to growLatest installations include universities inSingapore, China & Canada, major carcompanies in Germany and Japan, leadingbattery suppliers in Korea and USA. THThas made the first sale to India for BatteryTesting. These have kept Stephen andDanny our two installation engineers verybusy.
Support – Yes we support all users byemail, phone, Skype freely into the futureover the complete life of the instrument.
