This paper reports and analyses experimental results showing the performances of two state-of-the art, com-mercially available storage systems, adequate for use onboard hybrid vehicles, i.e. a supercapacitor (SC) and a super-high power lithium battery. The two devices were subjected to specific experimental tests adequate to ease comparisons for use onboard hy-brid vehicles. The results are expressed mainly in terms of specific power and charge/discharge efficiency as a function of the wanted discharge time; they show that, if future cycle efficiency analyses do not reverse the result, very high power lithium batteries are a very competitive candidate for use as onboard storage within hybrid vehicles, when storage of a single technology are considered.

Abstract
This paper reports and analyses experimental results showing the performances of two state-of-the art, com-mercially available storage systems, adequate for use onboard hybrid vehicles, i.e. a supercapacitor (SC) and a super-high power lithium battery. The two devices were subjected to specific experimental tests adequate to ease comparisons for use onboard hy-brid vehicles. The results are expressed mainly in terms of specific power and charge/discharge efficiency as a function of the wanted discharge time; they show that, if future cycle efficiency analyses do not reverse the result, very high power lithium batteries are a very competitive candidate for use as onboard storage within hybrid vehicles, when storage of a single technology are considered.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
