  • DEVICE FOR BALANCING THE CHARGE OF THE ELEMENTS OF A POWER BATTERY
    Publication number: 20160197498
    Abstract: A device for balancing charge of an electric power storage device including: a plurality of electrical storage elements connected in series including at least two current limiting DC/DC converters each including: an input configured to be connected to terminals of a respective storage element; an output configured to be connected to an electrical network having a voltage controlled at a lower level than the voltage at the terminals of the storage device; a transformation law of following type: Vout=K1*Ve?f(I) for 1<=1 lim, in which Vout is potential difference at the output, K1 is a constant, Ve is potential difference at the input, f(I) is an affine function of current I delivered at the output, and 1 lim is current limitation of the converter.
