ENERGY STORAGE DEVICE POWER CONSUMPTION MANAGEMENT

摘要

An energy storage device includes a device controller, an electrical energy converter, an energy storage medium and a power metering device. In a method of managing electrical power consumption by a group of the energy storage devices, a measured power level is output 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 a system controller using the device controllers. An aggregate power level is calculated based on the measured power levels, and is stored in memory using the system controller. In some embodiments, the aggregate power level is communicated to a remote location, such as an electrical power distribution system.
