Electrical Power Time Shifting
First Claim
1. A method comprising:
- monitoring, by an energy management system comprising at least one processor and an electrical energy storage device, a status of the electrical energy storage device;
receiving, at the energy management system, a first demand from a first power load for electrical power;
determining, by the energy management system, whether to supply the electrical power to satisfy the first demand from the electrical energy storage device or from one or more power sources connected to the energy management system, the determining comprising applying an algorithm to determine a power provision arrangement based on at least one preset criteria, the algorithm having data input comprising the status of the electrical energy storage device, one or more load characteristics of the first power load and any other loads supplied with electrical power from the energy management system, and one or more source characteristics of each of the one or more power sources; and
supplying the electrical power to the first power load in satisfaction of the first demand, the supplying occurring in accordance with the determined power provision arrangement.

Abstract
An energy management system and method can include functions such as monitoring a status of the electrical energy storage device; receiving a first demand from a first power load for electrical power, and determining whether to supply the electrical power to satisfy the first demand from the electrical energy storage device or from one or more power sources connected to the energy management system. The determining can include applying an algorithm to determine a power provision arrangement based on at least one preset criteria. The algorithm can have data input that includes the status of the electrical energy storage device, one or more load characteristics of the first power load and any other loads supplied with electrical power from the energy management system, and one or more source characteristics of each of the one or more power sources. Electrical power can be supplied to the first power load in satisfaction of the first demand and in accordance with the determined power provision arrangement.

11. An energy management system comprising:
-
an electrical energy storage device; a power bus connected to the electrical energy storage device and configured to receive electrical power from one or more power sources and to deliver the electrical power to one or more power loads; and at least one processor, the processor performing operations comprising; monitoring a status of the electrical energy storage device; receiving, from a first power load of the one or more power loads, a first demand for electrical power; and determining whether to supply the electrical power to satisfy the first demand from the electrical energy storage device or from the one or more power sources, the determining comprising applying an algorithm to determine a power provision arrangement based on at least one preset criteria, the algorithm having data input comprising the status of the electrical energy storage device, one or more load characteristics of the first power load and any other loads supplied with electrical power from the energy management system, and one or more source characteristics of each of the one or more power sources; and commanding supply of the electrical power to the first power load via the power bus in satisfaction of the first demand, the supplying occurring in accordance with the determined power provision arrangement. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
