Note 1 to entry: An EES system can have several points of connection arranged in two different classes: primary POC and auxiliary POC. From an auxiliary POC, it is not possible to charge electrical energy, in order to store it internally, and, finally, discharge it to the electric power system, but a primary POC can be used to feed the auxiliary subsystem and the control subsystem. In the absence of an auxiliary POC, the primary POC can be referred to simply as the "POC".
