INTELLIGENT BATTERY CONTROLLER

Various arrangements of intelligent battery controller devices are presented herein. A intelligent battery controller device can include a power input interface that receives power from a power source for charging a battery and a power output interface that outputs power from the battery. The intelligent battery controller device can include a power monitor and control system that monitors: an output power output by the battery to one or more external devices via the power output interface; and an input power received by the battery via the power input interface. Based on the output power and the input power, the intelligent battery controller device may determine a power level of a plurality of predefined power levels. A power level message can be transmitted to an external device that receives power from the intelligent battery controller device.
