Modular regulator circuit, for a modular electrical storage cell battery, having a number of modules dependent on the number of modules of the battery
First Claim
1. A regulator circuit for a battery of electrical storage cells, and in particular for a battery whose voltage is a function of its state of charge and which is constituted by "n" identical modules ("n" being an integer) connected in series between end terminals of the battery, the circuit comprising "n-1" regulation modules each respectively associated with two series-connected modules of the battery, each regulation module including regulator means for bringing the voltage across the terminals of each of the two series-connected battery modules with which it is associated to a common value by diverting current taken from the terminals of that one of the modules which provides the greater voltage until said greater voltage is reduced to the same value as the voltage present across the terminals of the module that has the smaller voltage.

Abstract
A regulator circuit for a battery of electrical storage cells, and in particular a battery whose voltage is a function of state of charge and which is constituted by "n" identical modules connected in series. The circuit comprises "n-1" regulation modules each associated with two series-connected modules of the battery, each regulation module includes means for bringing the voltage across the terminals of each of the two series-connected battery modules with which it is associated to a common value by diverting current taken from across the terminals of the module which provides the greater voltage across its terminals, end until said greater voltage has been reduced to the value present across the terminals of the module providing the smaller voltage.
