Abstract: A power system with a combination of active current sharing and droop current sharing is disclosed. The power system includes a system load and plural power supplies connected with each other and connected to the system load. The power supplies are configured to respectively output a load current to the system load, and each power supply includes an active current sharing circuit and a droop current sharing circuit. The active current sharing circuit is configured to enter an operation or shutdown mode depending on whether the load current is higher than a first current set point. The droop current sharing circuit is configured to enter an operation or shutdown mode depending on whether the load current is higher than a second current set point. Hence, each power supply can respectively output an equal share of the load current by an active current sharing technique and/or a droop current sharing technique.

Abstract: Disclosed is an Ping-Pong Type Battery Management system. The Ping-Pong Type Battery Management system includes first and second battery packs, first and second battery switches, a sensing and controlling module, a supply power regulation module and a load power regulation module. The first battery switch is formed on the first battery pack. The second battery switch is formed on the second battery pack. The sensing and controlling module is connected to the first and second battery packs and the first and second battery switches. The supply power regulation module is connected to the first and second battery switches. The load power regulation module is connected to the first and second battery switches.
