主权项

1. An apparatus for battery balancing, comprising:
a power conditioning system: a plurality of batteries connected with the power conditioning system in parallel; relays disposed between the power conditioning system and the batteries in series; and a manager connected to the power conditioning system, the batteries, and the relays, respectively and monitoring voltages of each battery, communicating with the power conditioning system when the batteries of which the voltage unbalance is sensed occur, determining the batteries to be balanced among the batteries of which the voltage unbalance is sensed, and determining a balancing mode to control the relays and transmitting a state of the battery to the power conditioning system, wherein the power conditioning system is configured to convert power into a predetermined output for battery balancing when receiving balancing request information by communicating with the manager.
