dynamic Charge Acceptance of lead acid batteries comparison of methods for conditioning and testing
Journal of Power Sources, 2012Co-Authors: Heide Buddemeiwes, Dirk Uwe Sauer, Julia Kowal, Dominik Schulte, Ralf Hecke, Eckhard KardenAbstract:Abstract Dynamic Charge Acceptance (DCA) is a key requirement for batteries in micro-hybrid vehicles. In automotive applications, DCA reaches a stable level during several weeks or months in service. A conditioning method that accelerates stabilizing DCA is presented. Various test methods for evaluation of DCA are compared. This is necessary for comparing new technologies (e.g. negative electrodes with carbon additives) and cell concepts (e.g. bi-polar batteries).

Study of Charge Acceptance for the lead-acid battery through in situ EC-AFM observation — influence of the open-circuit standing time on the negative electrode
Journal of Power Sources, 2001Co-Authors: Yoshiaki Yamaguchi, Masashi Shiota, Masaaki Hosokawa, Yasuhide Nakayama, Nobumitsu Hirai, Shigeta HaraAbstract:An influence of the open-circuit standing time after oxidation of the lead electrode was investigated for understanding Charge Acceptance of the negative electrode of a lead-acid battery. It was confirmed by a potentiostatic transient experiment that Charge Acceptance of the lead electrode heavily depended on the standing time before charging, and Charge Acceptance decreased if the standing time was longer. This tendency was conspicuous at the initial period of the reduction process in particular. When the behavior of the lead electrode surface during the open-circuit standing after oxidation was observed by in situ electrochemical atomic force microscope (EC-AFM), it was found that some lead sulfate crystals gradually grow with time to bigger crystals having a smooth surface, retaining basically its morphology of previous one. We have concluded that the standing time dependence of the Charge Acceptance is caused by this behavior of the crystals. Also, it was confirmed that Charge Acceptance of a valve regulated lead-acid (VRLA) battery with different standing times can be explained by result of the potentiostatic transient test and the EC-AFM observation.
