Power managers and methods for operating power managers
First Claim
1. A power manager comprising:
- a power bus operable at a DC bus voltage;
a plurality of device ports operably connectable to the power bus;
a first data processing device and a first memory device associated with the first data processing device;
a data communication channel extending between the first data processing device and each of the plurality of device ports;
an energy management schema operating on the first data processing device;
wherein for each of the plurality of device ports, the energy management schema establishes a communication link with an external power device connected to the device port over the data communication channel and determines if an external power device is connected to the device port and if so, determines an external power device type andeach of the plurality of device ports further comprises;
a first power channel disposed between the device port and the power bus; and
a first controllable switching element operable by the data processing device disposed along the first power channel between the device port and the power bus.

Abstract
A power manager including a power bus operable at a DC bus voltage. A plurality of device ports operably connect to the power bus. A first data processing device and a first memory device are associated with the first data processing device. A data communication channel extends between the first data processing device and each of the plurality of device ports. An energy management schema operates on the first data processing device. For each of the plurality of device ports, the energy management schema establishes a communication link with an external power device connected to the device port over the data communication channel and determines if an external power device is connected to the device port and if so, determines an external power device type.
