1. A balancing system of a high-voltage or medium-voltage network comprising:
a network input incorporating protection units for protecting said network and units for measuring the performance of said network in order to detect the balancing requirements;
a transformer having a first winding connected to the output of said network input and configured to lower the voltage of said network;
an inverter connected to a second winding of said transformer and configured to transform an AC voltage into a DC voltage;
a set of batteries connected to said DC voltage; and
a supervision unit configured to activate said inverter and to charge or discharge said batteries when an imbalance is measured on said network by said measurement units;
wherein said balancing system also includes an additional inverter connected to a third winding of said transformer, the output of which makes possible the supply of power to at least one charging socket of an electric or hybrid vehicle; and means for detecting a charging requirement of said charging socket;
said supervision unit being configured to activate said additional inverter when a charging requirement is detected at said charging socket and the requirements for injection into the network are less than a threshold value.
