Abstract
Official abstract text for this publication.
A battery state detector includes a main unit configured to detect a state of one battery assembly in a battery pack storing therein a plurality of battery assemblies each including a plurality of battery cells arranged in rows, a subunit configured to detect a state of a battery assembly in the battery pack other than the battery assembly that is a detection target of the main unit, and a first communication line that connects the main unit with the subunit. The main unit is connected to a controller configured to control the battery pack via a second communication line that is separate from the first communication line.
First claim
Opening claim text (preview).
What is claimed is: 1 . A battery state detector comprising: a main unit configured to detect a state of one battery assembly in a battery pack storing therein a plurality of battery assemblies each including a plurality of battery cells arranged in rows; a subunit configured to detect a state of a battery assembly in the battery pack other than the battery assembly that is a detection target of the main unit; and a first communication line that connects the main unit with the subunit, wherein the main unit is connected to a controller configured to control the battery pack via a second communication line that is separate from the first communication line. 2 . The battery state detector according to claim 1 , wherein the main unit receives a detection result of the subunit from the subunit via the first communication line, and the main unit transmits management information based on the detection result of the subunit and a detection result of the main unit to the controller via the second communication line. 3 . The battery state detector according to claim 1 , wherein the main unit is integrated with a busbar module that electrically connects the battery cells in the battery assembly, a state of the battery assembly being detected by the main unit, and the subunit is integrated with a busbar module that electrically connects the battery cells in the battery assembly, a state of the battery assembly being detected by the subunit. 4 . The battery state detector according to claim 2 , wherein the main unit is integrated with a busbar module that electrically connects the battery cells in the battery assembly, a state of the battery assembly being detected by the main unit, and the subunit is integrated with a busbar module that electrically connects the battery cells in the battery assembly, a state of the battery assembly being detected by the subunit.
