Abstract
A battery system includes a plurality of battery modules connected in parallel. Each battery module includes a battery, a first output terminal and a second output terminal, a switch circuit connected between the battery and the first output terminal, and a battery manager to detect a battery voltage of the battery and control the switch circuit. Each battery manager is connected to other battery managers through a communication bus and transmits module information of a corresponding battery module to the other battery managers through the bus. Each batter manager also receives module information from the other battery managers through the bus and controls a corresponding switch circuit based on the module information.
