Evaluation of a High Voltage Battery Under Pulsed Loads
Abstract
Electrochemical energy storage devices, such as lithium-ion batteries, are being considered for use inmany shipboard electrical power systems. In some cases the energy storage will serve primarily as backuppower however in many applications, the energy storage will serve as the prime power source. Currently,it is proposed that batteries be configured with open circuit potentials as high as 1000 VDC. The batterieswill be constructed in the form of large series strings of individual cells to obtain the high voltage requiredand then strings will be paralleled to obtain the capacity needed to supply the high energy and high powerloads. The Navy has worked with a number of different energy storage vendors to specify the requirementsfor future shipboard power systems. The results of many trade studies have led to the design anddevelopment of a few different battery systems that are nearing completion of the development phase andthat are nearing the research and evaluation phase. To that end, the University of Texas at Arlington (UTA)Pulsed Power and Energy Laboratory (PPEL) proposes a research effort in which they will assist the Navyin evaluating newly developed technologies. Utilizing expertise and laboratory hardware already in place,the PPEL will develop a research test plan in which the battery(s) of interest to the Navy, and that is suppliedby the Navy, are stressed to the limits specified by the manufacturer both electrically and thermally. Theoutcome of the research will be a better understanding of how these new technologies perform when theyare utilized to power future shipboard transient load profiles.
