Abstract
An electrical power supply system has electrical energy storage modules and an interconnection interface. Each module includes connection terminals of opposite polarities and an energy storage element connected between them. The interface includes pairs of input terminals and output terminals for a load's power supply. Each pair of input terminals connects removably to connection terminals of a respective storage module. The interface forms parallel branches between the two output terminals. Each includes a storage element. Each branch includes a rheostat in series with a corresponding storage element of the branch. The interface includes a device for measuring current passing through each of the branches, and a control circuit for controlling resistances of the rheostats of the branches as a function of the measured current so as to maintain a current intensity passing through the rheostats to be below a threshold.
