An electric vehicle includes a battery modules electrically connected in parallel and having the same nominal module voltage, a determination device for determining a battery state parameter representing a state of charge of the battery module; a switching system to switch current paths of the battery modules to be conducting or blocking; an energy management system configured to, if a battery module has a state of charge that is noticeably lower than a state of charge of another battery modules, switch the current path of the battery module with the lower state of charge to be blocking during a driving mode until the charging state of the battery module with the higher state of charge is balanced with the charge state of the battery module with the lower state of charge, and then switch the current path of the battery module with the lower state of charge to be conductive.
