Abstract: Es wird ein Verfahren zum Schätzen eines Ladezustandes einer Lithium-Ionen-Batterie zur Verfügung gestellt, bei der eine Lithium-Phosphat-Verbindung mit einer Kristallstruktur vom Olivintyp für eine positive Elektrode verwendet wird und ein aktives Material, das aufgrund einer Insertions-/Desorptionsreaktion von Lithium keine Potentialfluktuation zeigt, für eine negative Elektrode verwendet wird, das auf einer Spannungsänderungsrate basiert. Das Verfahren weist Folgendes auf: einen ersten Schritt des Speicherns eines Diagramms, das eine Korrespondenzrelation zwischen der Spannungsänderungsrate und dem Ladezustand bei einer Mehrzahl von Lade-/Entladeraten repräsentiert; einen zweiten Schritt des Erhaltens eines Kandidaten für einen vorliegenden Ladezustand aus einer tatsächlich gemessenen Spannungsänderungsrate, die auf der Grundlage eines während des Ladens/Entladens gemessenen Werts berechnet wird, durch Bezugnahme auf das Diagramm; und einen dritten Schritt des Erhaltens des vorliegenden Ladezustandes durch einen Vergleich zwischen dem Kandidaten für den Ladezustand, der während des Ladens erhalten worden ist, und dem Kandidaten für den Ladezustand, der während des Entladens erhalten worden ist. Es wird ein Verfahren zum Schätzen eines Ladezustandes einer Lithium-Ionen-Batterie zur Verfügung gestellt, bei der eine Lithium-Phosphat-Verbindung mit einer Kristallstruktur vom Olivintyp für eine positive Elektrode verwendet wird und ein aktives Material, das aufgrund ei ...more ...less

Abstract: A method of estimating a state of charge of a lithium ion battery, which uses a lithium phosphate compound having an olivine-type crystal structure for a positive electrode and uses an active material exhibiting no potential fluctuation due to an insertion/desorption reaction of lithium for a negative electrode, based on a voltage change rate. The method includes: storing a map representing a correspondence relationship between the voltage change rate and the state of charge at a plurality of charging/discharging rates; obtaining a candidate for a present state of charge from an actually measured voltage change rate, by referring to the map; and obtaining the present state of charge through a comparison between the candidate for the state of charge obtained during the charging and the candidate for the state of charge obtained during the discharging.

Abstract: In a power supply system using various kinds of storage batteries such as a large capacity storage battery or a small capacity storage battery, an electric power path is complicated, which may increase failures such as a short circuit trouble. There is a problem in that, when a short circuit trouble between storage batteries occurs, damage to a smaller capacity storage battery is serious. Accordingly, in a power supply system according to the present invention, the relationship among voltages, current capacities, and electric power capacities of various kinds of storage batteries such as a large capacity storage battery or a small capacity storage battery is defined so that damage to the storage batteries may be minimized even when malfunction occurs in, for example, switching a switch, and energy transfers from a higher voltage storage device.
