1. A smart charge system comprising:
- a control computer;
a system sensor configured to measure power drawn by at least one premises load, and to send system sensor information to the control computer, 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; and
at least one energy storage unit configured to switch between at least two modes of operation, monitor a current state of charge of the energy storage unit, and send energy storage unit information comprising the current state of charge to the control computer, wherein the at least two modes of operation include a charge mode and a discharge mode;
the control computer being configured to switch 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.

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.

18. A non-transitory computer-readable medium including instructions that, when executed by a processor, cause the processor to perform the steps of:
-
measuring power drawn by at least one premises load via a system sensor; sending system sensor information to a control computer, 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; monitoring a current state of charge of at least one energy storage unit configured to switch between a charge mode and a discharge mode; sending energy storage unit information comprising the current state of charge to the control computer; and transmitting, from a control computer to at least one energy storage unit, a mode switch instruction to switch the mode of operation of the energy storage unit between the charge mode and the discharge mode based on the system sensor information and the energy storage unit information. - View Dependent Claims (19, 20)
