BATTERY WITH SWITCHED ACCUMULATORS

A battery including: a power supply bus; an assembly of electric cells and of first switches coupling the cells; second switches forming an H bridge and coupling said assembly to nodes; a first circuit for supplying first control signals to the first and second switches; a second circuit for delivering a first power supply voltage to the first circuit based on the voltage across one of the cells; a third circuit for supplying second control signals to at least two of the second switches and connected to the power supply bus; and first diodes coupling the first circuit to the two second switches and second diodes coupling the third circuit to the two second switches.
