Battery could be connected to the controller and in this case controller will provide a battery-monitor function. The power-supplies phandle property is needed in order to describe the power supply which is used for charging of the battery, this allows to determine whither battery is charging or discharging, depending on the supply state. The monitored-battery phandle provides information about the battery cell characteristics.
