1. A modular device for the accumulation and delivery of electrical energy comprising a structure comprising
a plurality of shelves,
an air conditioning system, and
at least one bi-directional multi-level electronic converter defining a transformerless type AC/alternating current output including
three legs three-phase connected to said output and each comprising a plurality of modules connected in series,
a plurality of inductors each arranged on a respective output line from said legs, and
a firmware control device configured to modify at least output current and voltage from said modules,
wherein each of said modules comprises:
a first stage AC output including an IGBT device, isolated towards ground wire, capable of connecting in series with said other modules of a respective said leg and capable of generating an output voltage waveform,
a second stage DC/DC conversion defining an input, and
at least one battery connected to said input,
and
wherein said battery is an electric vehicle battery (EVB).
