CONTRIBUTIONS TO ELECTRIC VEHICLE POWER SAFETY THROUGH BATTERY TESTING CALORIMETRY (BTC)

摘要

Extensive on-going research into the development of large scale batteries for applications such as motor vehicles has raised issues about safety, bearing in mind the potentially explosive and toxic nature of the chemicals involved. This article presents the total redesign and testing of a well known Adiabatic Reaction Calorimeter (ARC*), to test the thermal safety of complete batteries and their components over a wide range of condition, often referred to as "abuse" testing. The resulting device, BTC, conforms to the basic design principles of the ARC* but focuses particularly on the safety aspects and flexibility of operation, allowing a wide range of tests to be performed easily. This paper will describe the important features of the BTC and show that the robust design has been achieved without compromising on accuracy of the results.
