* <p>
|

* This Battery updates energy after each mote tick:
|

* the energy consumption of each interface is summed up.
|

* In addition, the Battery adds the CPU energy.

* This observable notifies every tick (relatively time-consuming).

|

* A Battery represents the energy source for a mote.
|

* The previous battery mote interface implementation was removed,
|
||||
* awaiting a new more powerful design connected to Contiki's power profiler.

* The current code does not monitor the energy consumption of simulated motes.
