Abstract
A battery system includes a battery assembly having a plurality of modules, which are controlled by a system control circuit, each module including a module control circuit and a module by-pass circuit which is controlled via the module control circuit so as to suppress the charging variation among the plurality of modules. Each control circuit and the system-controlling circuit are connected to each other via a bilateral transmission medium and each module by-pass circuit is controlled based on information bilaterally transmitted between each module control circuit and the system control circuit via the bilateral transmission medium.
