    Abstract: A module for an electrochemical battery including plural accumulators electrically connected together by connection elements, a mechanism for electrical connection of the module with an exterior and a continuous envelope made from a dielectric polymer material that covers exterior surfaces of the accumulators, and connection elements that do not cover the mechanism for electrical connection of the module with the exterior. The continuous envelope is made by soaking to ensure coating of the accumulators and of the one or more connecting elements. The plural accumulators are distributed into plural layers, arranged in relation to each other so that one or more passages are made between the accumulators, wherein the continuous envelope covers a surface of the accumulator or accumulators delimitating the passages between the accumulators.

  • Patent number: 10027000
    Abstract: An accumulator battery system includes series-connected accumulators with potentials across stages powering corresponding controllers that measure potential differences between terminals of accumulators. A first analog-to-digital converter encodes the potential measured between terminals of an accumulator. A first output delivers a first digital sequence corresponding to the encoded potential difference, logic levels of which are defined by at least two potentials across the first-stage accumulator terminals. A decoder decodes a potential measured by the first control-device from the first digital sequence. A second analog-to-digital converter selectively encodes a potential difference measured between terminals of a second-stage accumulator of the second stage and two potentials of the digital sequence received on the input.

  • Patent number: 9606165
    Abstract: An electrical power supply includes DC source outputting Vm and a device that detects insulation defects in the DC source. The device includes input terminals connected to the source's terminals, impedances Z1 and Z2 connected in series between the input terminals, where Z1=Z2=Z and Vm/Imax<z<(3/2)*Vm/Imax, wherein Imax is a maximum insulation defect current defined by a standardized safety threshold, and a current-detection circuit connected between ground and an intermediate point between the impedances. The current-detection circuit includes a microcontroller that receives a voltage proportional to the defect current originating from the intermediate point, the input terminal being connected by Z3 to a power supply with Vcc<Vm, the input terminal being connected to ground by way of Z4. The microcontroller is configured to determine amplitude of an insulation defect as a function of the voltage applied to the input terminal, wherein Z*Vcc/(4*Vm)<(Z3,Z4)<Ztmax=Z*Vcc/2Vm.
