- * 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).
- *
- * When the energy left is below 0 the mote is dead.
- *
+ * 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.
