PORTABLE POWER MANAGER
First Claim
1. A power manager comprising:
- a power bus (410);
a plurality of device ports each configured to operably connect with an external power device;
a first power channel (525, 1305) comprising a first conductive path disposed between each device port and the power bus and a first controllable switching element (465, A) disposed along the first connective path for selectively connecting and disconnecting each device port to and from the power bus over the first power channel;
a second power channel (530, 1320) comprising a second conductive path disposed between each device port and the power bus, a second controllable switching element (495, D) disposed along the second connective path for selectively connecting and disconnecting each device port to and from the power bus over the second power channel and a controllable power converter (442) disposed along the second conductive path between the second controllable switching element and the power bus for converting a power signal;
a data processing device (420) and associated memory in communication with each of the first and second controllable switches and the power converter; and
,energy management schema operating on the power manager for controlling each of the first and second controllable switches and the power converter.

Abstract
A portable DC power manager (400) includes an internal power bus (410) and a plurality of device ports (1150, 1160, 1170, 1180, 1190, 1200) for connecting with external power and energy sources, external power loads and other external power managers. Each device port is isolated for the internal power bus by controllable switches (A, B, C, D). Power converters (440, 442, 510) may be disposed between device ports and the internal power bus to convert voltages and attenuate current amplitude. Energy management schema operating on the power manager sums available power and allocates the available power to connected power loads according to power priority settings. A hot-change-over circuit (1300) connects additional sources to the internal bus in response to a voltage drop on the internal power bus. A compact and lightweight package (1100) enables a portability.

28. A power manager comprising:
-
a power bus (410); a plurality of device ports each configured to operably connect with an external power device; a first power channel (525, 1305) comprising an first conductive path disposed between each device port and the power bus and a first controllable switching element (465, A) disposed along the first conductive path for selectively connecting and disconnecting each device port to and from the power bus over the first power channel; a backup power channel comprising a backup conductive path disposed between each device port and the power bus, a first backup controllable switching element (B) and a second back up controllable switching element (C) each disposed along the backup conductive path; a sensor (1315) for sensing a low power condition on the power bus and for generating a low power signal in response thereto; a conductive path (1340) extending between the sensor and the second backup controllable switching element (C) associated with each device port such that the low power signal generated by the sensor causes each of the second backup controllable switches (C) to close in response thereto. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35, 36, 37, 38)
