Abstract

A battery module includes a plurality of battery cells, and includes a voltage bus bar and a voltage / current bus bar that connect electrodes of the plurality of battery cells to one another. Solder traces are formed in regions that are spaced apart from each other in the voltage / current bus bar. Furthermore, the battery module includes an amplifying circuit and a detecting circuit. The amplifying circuit amplifies a voltage between the solder traces formed in the voltage / current bus bar. The detecting circuit detects the voltage between the solder traces amplified by the amplifying circuit.

Description

technical field [0001] The present invention relates to a battery module, a battery system including the battery module, and an electric vehicle. Background technique [0002] As a drive source for mobile vehicles such as electric vehicles, chargeable and dischargeable battery modules are used. Such a battery module has, for example, a configuration in which a plurality of batteries (battery cells) are connected in series. [0003] A user of a mobile body including a battery module needs to know the remaining battery capacity (charged amount) of the battery module. In addition, when charging and discharging the battery module, it is necessary to prevent overcharging and overdischarging of each battery constituting the battery module. Therefore, a device for monitoring the state of a battery module has been proposed (for example, refer to Japanese Patent Application Laid-Open No. 8-162171). [0004] Japanese Patent Application Laid-Open No. 8-162171 describes a monitoring ...
