1. A smart charge system, comprising:
- a control computer that is configured to;
receive system sensor information from a system sensor configured to measure power drawn by at least one premises load, the system sensor information comprising an indication of the power drawn and a timestamp corresponding to the time at which the power drawn is measured;
receive energy storage unit information from at least one energy storage unit that is configured to switch between at least two modes of operation, and monitor a current state of charge of the energy storage unit, wherein the at least two modes of operation include a charge mode and a discharge mode; and
cause the mode of operation of the at least one energy storage unit to switch between the charge mode and the discharge mode based on the system sensor information and the energy storage unit information.

Abstract
The invention provides systems and methods for control of power charge/discharge from energy storage system. The invention also provides for power monitoring and management. A smart charge system may include a system sensor, one or more energy storage units, and a controller, which may receive information about the power demand, power provided by an electricity provider, and charge/discharge information from an energy storage unit. The information received may all be time synchronized in relation to a time based reference. The controller may provide instructions to an energy storage unit at a rapid rate.

7. A method of power monitoring and management, comprising:
-
receiving system sensor information from a system sensor configured to measure power drawn by at least one premises load, the system sensor information comprising an indication of the power drawn and a timestamp corresponding to the time at which the power drawn is measured; receiving energy storage unit information from at least one energy storage unit that is configured to switch between at least two modes of operation, and monitor a current state of charge of the energy storage unit, wherein the at least two modes of operation include a charge mode and a discharge mode; switching the mode of operation of the at least one energy storage unit between the charge mode and the discharge mode based on the system sensor information and the energy storage unit information; and transmitting a mode switch instruction that causes the mode of operation of the energy storage unit to switch between the charge mode and the discharge mode based on the system sensor information and the energy storage unit information. - View Dependent Claims (8, 9, 10)

11. A non-transitory computer-readable storage medium including instructions that, when executed by a control computer, cause the control computer to monitor and manage power, by performing the steps of:
-
receiving system sensor information from a system sensor configured to measure power drawn by at least one premises load, the system sensor information comprising an indication of the power drawn and a timestamp corresponding to the time at which the power drawn is measured; receiving energy storage unit information from at least one energy storage unit that is configured to switch between at least two modes of operation, and monitor a current state of charge of the energy storage unit, wherein the at least two modes of operation include a charge mode and a discharge mode; switching the mode of operation of the at least one energy storage unit between the charge mode and the discharge mode based on the system sensor information and the energy storage unit information; and transmitting a mode switch instruction that causes the mode of operation of the energy storage unit to switch between the charge mode and the discharge mode based on the system sensor information and the energy storage unit information. - View Dependent Claims (12, 13, 14)
