| 20130020982 | EQUALIZATION SYSTEM FOR ACCUMULATOR BATTERIES - An apparatus comprising a charge equalizing system for batteries has two accumulator stages in series. Each stage has a charging device having an inductance for storing energy, and first and second diodes. The first diode's anode links to a negative pole of the accumulator stage. Its cathode links to the inductance's first end. The second diode's cathode links to a positive pole of the accumulator stage; its anode links to the inductance's second end. A first controlled switch links to a battery's negative pole and to the second diode's anode. A second controlled switch links to the battery's positive pole and to the first diode's cathode. A control device controls the charging devices. The control device closes the switches of a charging device associated with the accumulator stage to be charged so that the inductance stores energy, and opens the switches to transfer the energy to the associated accumulator stage. | 01-24-2013 |
| 20130038290 | CHARGE EQUALIZATION SYSTEM FOR BATTERIES - An equalization system for batteries has two series-connected accumulator stages connected, each including an accumulator, a voltage generator including positive and negative poles, for each stage, an associated charging device supplied by the voltage generator. The charging device includes an inductor having a first and second ends, and a capacitor having first and second ends. The capacitor's first end connects to the generator's positive pole. It also has a diode whose anode connects to a negative pole of the accumulator stage and whose cathode connects to the inductor's first end. It also has a switch whose first end connects to the inductor. And it also has a control device that controls the generator and closes a switch of a charging device associated with an accumulator stage to be charged so that the inductor stores energy, and causes its transfer to that accumulator stage. | 02-14-2013 |

| 20140084935 | DEVICE FOR DETECTING A DEFECT IN INSULATION - 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| 03-27-2014 | |
| 20140103939 | DETECTION OF AN INSULATION DEFECT - An electrical power supply device includes a DC voltage source with terminals, a controller, and an insulation-defect detecting device for detecting an insulation defect of the voltage source. The device has input terminals connected to source terminals, and circuits connected between respective input terminals and an intermediate point. The insulation-defect current-detection circuit connects between ground and the intermediate point. Both circuits have current-limiter circuits that open and close a connection between respective inputs and the intermediate point. Both current-limiter circuits are rated for traversal by a current of less than a standardized safety threshold when the first current-limiter circuit is closed and one of the terminals of the DC voltage source is shorted to ground. The control circuit is configured to simultaneously keep one current-limiter circuits open and the other closed. | 04-17-2014 |
