An energy storage device (104) includes a device controller (106), an electrical energy converter (108), an energy storage medium (110) and a power metering device (170). In a method of managing electrical power consumption by a group of the energy storage devices, a measured power level (172) is output (174) from the power metering device of each energy storage device. The power level represents a rate of electrical energy consumption by the electrical energy converter of the device. The measured power levels of each of the devices are communicated (176) to a system controller (102) using the device controllers. An aggregate power level (184) is calculated (178) based on the measured power levels, and is stored (180) in memory (124) using the system controller. In some embodiments, the aggregate power level is communicated (190) to a remote location, such as an electrical power distribution system (112). |
