Verfahren und Vorrichtung zur Detektierung der Anomalien einer Batterie-Parallelanschlussschaltung

摘要

In a method for detecting abnormality in a parallel battery-connection circuit (1), the parallel battery-connection circuit includes: a first circuit including a first plurality of batteries connected in series (3) and a second circuit including a second plurality of batteries connected in series (4); wherein: at least one of the first plurality of batteries is connected to a first temperature detection section (5A), at least one of the second plurality of batteries is connected to a second temperature detection section (5B), and the first temperature detection section and the second temperature detection section are connected to an abnormality determining section (6) for determining abnormality in the parallel battery-connection circuit, the method comprising the steps of: detecting a first temperature of the at least one of the first plurality of batteries by the first temperature detection section; detecting a second temperature of the at least one of the second plurality of batteries by the second temperature detection section; and determining abnormality in the parallel battery-connection circuit by the abnormality determining section based on a temperature difference between the first temperature detected by the first temperature detection section and the second temperature detected by the second temperature detection section.
