The energy behavior of the 48th node during two charging periods. The 48th node has the highest power consumption among all nodes in the network. The energy behavior of each node is periodic and can be calculated after the implementation of ERSVC. Similarly, we can also obtain the energy behavior for other nodes. If the remaining energy of a node’s battery is always higher than Emin, it will remain operational forever
