BATTERY CHARGER SYSTEM

Abstract: a battery charger system includes multiple power channels to accommodate multiple battery chargers through a power input port. each power channel includes a power outlet electrically coupled to the power input port through a relay. each power channel further includes a current sensor. a controller is configured to estimate current in each of the power channels using the sensor signals, and configured to control the relays. the battery charger system is configured to provide power to the outlets by closing the corresponding relays, until the total current estimate is more than a maximum current limit, at which point the controller is configured to open the most recently closed relay. the controller is further configured to sequentially close remaining relays after the total current drops sufficiently, while maintaining the total current below the maximum current limit.
