摘要

PURPOSE: A battery module, a battery system including thereof, and an electric powered vehicle are provided to detect the current flowing through plural battery cells with a simple structure. CONSTITUTION: A battery module(100) comprises the following: plural battery cells(10); a connecting member connecting at least two electrodes on the battery cells; a voltage detecting unit detecting the voltage at the portion in between a first region and a second region separated with each other on the connecting member; and a wiring substrate including first and second conductor patterns, electrically connected to the voltage detecting unit. The connecting member is a metal plate including the first and second regions.
