Abstract
This device comprises a rectifier-inverter supplied with current by the mains and adapted to deliver a charging current to the battery in the course of the charging periods of the battery and to restore to the mains the discharge current of the battery in the course of the discharging periods of the battery, a direct current chopper for chopping the current of the battery at an available conduction rate in the course of the simulation of the cycle of operation, a switch connected between the rectifier-inverter and the chopper and circuits for automatically controlling the chopper, the switch and the rectifier-inverter as a function of the cycle of operation of the battery to be simulated.
