Abstract:

© 2015 The Authors. Published by Elsevier Ltd. Ultracapacitors (UCs) are being increasingly studied and deployed as a short-term energy storage device in various energy systems including uninterruptible power supplies, electrified vehicles, renewable energy systems, and wireless communication. They exhibit excellent power density and energy efficiency. The dynamic behavior of a UC, however, strongly depends on its impedance characteristics. In this paper, the impedance characteristics of a commercial UC are experimentally investigated through the well-adopted Electrochemical Impedance Spectroscopy (EIS) technique. The implications of the UC operating conditions (i.e., state of charge (SOC) and temperature) to the impedance are systematically examined. The results show that the impedance is highly sensitive to temperature and SOC; and the temperature effect is more significant. The experimental design and multi-condition impedance analysis provides prudent insights into UC system integration, dimensioning, and energy management strategy synthesis in advanced energy systems.
