Abstract
A battery system includes a first battery, a second battery, and a battery manager. The first battery is electrically connected between a first node and a second node via a first module switch in a short circuit state. The second battery is electrically insulated from the first battery by a second module switch in an open circuit state. The battery manager detects a first battery voltage of the first battery, a second battery voltage of the second battery, and a system current flowing between the first and second nodes, determines an open circuit voltage of the first battery based on the first battery voltage and the system current, and short-circuits the second module switch when the open circuit voltage is substantially equal to the second battery voltage so that the at least one second battery is connected to the at least one first battery in parallel.
