Guerin, J. T. and Andrew Burke (1997) Load Leveled Battery System Characteristics Using Sealed Lead-Acid Batteries. Proceedings of the 32nd Intersociety Energy Conversion Engineering Conference (IECEC-97) 2, 883 - 888
The characteristics of a load leveled battery system were studied experimentally using a 36 V pack of sealed lead-acid batteries (38 Ah, 12 V modules) as the energy source and a 24 V pack of the same batteries as the pulse power unit. Control strategy for the load leveling was implemented such that the results could be easily interpreted relative to the use of ultracapacitors as the pulse power unit. The system response and test results are in good agreement with previously published SIMPLEV simulations of battery load leveling with pulse power batteries and ultracapacitors in electric vehicles and show the importance of high efficiency control electronics and the expected high charge/discharge efficiency of ultracapacitors to optimize system performance.
