| 20090066318 | SENSOR DEVICE WITH ALTERNATING EXCITATION FIELDS - The invention relates to a magnetic sensor device comprising excitation wires ( | 03-12-2009 |
| 20100036627 | APPARATUS AND METHOD FOR DETERMINATION OF THE STATE-OF-CHARGE OF A BATTERY WHEN THE BATTERY IS NOT IN EQUILIBRIUM - The invention relates to a method and an apparatus, like a charger for determining the state-of-charge of a battery which has been charged or discharged and which has not reached its equilibrium state, the method comprising the steps of determining the EMF of the battery by extrapolation of the battery voltage sampled during relaxation after the charge or the discharge process, wherein the extrapolation is based on a model using only variables sampled during the relaxation process and deriving the state-of-charge from the EMF of the battery by using a predetermined relation between the EMF and the state-of-charge. This method is a voltage-prediction method without the need to store parameters beforehand. Instead, the voltage relaxation end value is determined based on the measured first part of a voltage relaxation curve and mathematical optimisation/fitting of a function to this measured part of the relaxation curve. | 02-11-2010 |
| 20100045240 | METHOD AND APPARATUS FOR DETERMINATION OF THE STATE-OF-CHARGE (SOC) OF A RECHARGEABLE BATTERY - The present invention relates to a method for determination of the state-of-charge (SoC) of a rechargeable battery as a function of the Electro-Motive Force (EMF) prevailing in said battery. The invention also relates to a method for measuring the relation between the state-of-charge (SoC) and the EMF. The invention further relates to an apparatus for determination of the State-of-Charge (SoC) of a rechargeable battery as a function of the Electro-Motive Force (EMF) prevailing in said battery. | 02-25-2010 |
| 20100148731 | METHOD AND CHARGER FOR BOOST CHARGING A CHARGEABLE BATTERY ON THE BASIS OF A PHYSICAL MODEL - The invention relates to a method of charging a rechargeable unit, such as a rechargeable battery or a rechargeable battery pack, wherein the charging current is larger than the nominal charging current (C) if at least one condition in the rechargeable unit is met, and wherein the at least one condition is continuously calculated from measurable variables of the rechargeable unit through a physics-based model. The invention also relates to a corresponding method. The features of the invention allow a continuous monitoring of the variables in the battery, so that a proper criterion is available for the decision if charging with high charge current is allowable without a reduction of the lifetime of the battery. | 06-17-2010 |
| 20100265030 | INDUCTIVE COMPONENTS FOR DC/DC CONVERTERS AND METHODS OF MANUFACTURE THEREOF - An inductive component for a DC/DC converter is made by transferring a copper track ( | 10-21-2010 |
| 20110031816 | PHOTOVOLTAIC UNIT, A DC-DC CONVERTER THEREFOR, AND A METHOD OF OPERATING THE SAME - A photovoltaic unit is disclosed comprising a plurality of sub-units connected in series, each sub-unit having a main input and a main output, which main output is connected to the respective main input of a neighbouring sub-unit, each sub-unit further comprising a segment comprising one or more series-connected solar cells, and a supplementary power unit, wherein the supplementary power unit is configured to at least one of receive power from or supply power to the neighbouring sub-unit. The supplementary power unit is preferably a DC-DC converter, and arranged to exchange energy between neighbouring segments, without requiring a high-voltage connection across the complete string (of more than 2 segments). The converter may be inductive or capacitive. | 02-10-2011 |
| 20110115297 | PHOTOVOLTAIC ASSEMBLY AND METHOD OF OPERATING A PHOTOVOLTAIC ASSEMBLY - A photovoltaic assembly is disclosed which comprises a string formed from a plurality of series-connected photovoltaic generators, and a hierarchical structure of power-exchange units, which each exchange power between neighbouring photovoltaic generators or groups of photovoltaic generators. | 05-19-2011 |
