While conventional storage systems, for example batteries, offer very limited electrical properties, for example DC voltage with a voltage which is prespecified by the battery design and the state of charge, the apparatus disclosed herein can deliver virtually any desired current and voltage profiles within certain limits, for example a maximum voltage and a maximum current, without the need for a separate power-electronics converter circuit. At the same time, the apparatus can not only output but also receive energy in virtually any desired form and charge its integrated electrical energy stores, for example capacitors, batteries, rechargeable batteries and the like, while maintaining prespecified charging properties, for example specific current and voltage profiles or power output profiles over time (for example constant, increasing with a specific profile or falling with a specific profile). | 2017-01-26 |
20170025867 | Balancing Series-Connected Electrical Energy Units - An apparatus and methods to fabricate the apparatus for balancing a string of N series-connected electrical energy units (such as battery cells or modules) comprising: a transformer with a magnetic core and N windings; N switch circuits; N driver circuits, each driver circuit operable to turn ON/OFF a respective switch circuit in a discharging or charging or idling configuration; and a controller circuit. In a novel way, the controller circuit selects each electrical energy unit for discharging or charging or idling, and controls simultaneously coupling all selected-for-discharging electrical energy unit(s) to respective winding(s) in discharging configuration(s) for a first period of time to simultaneously energize the respective winding(s); then immediately or after a short delay, the controller circuit controls simultaneously coupling all selected-for-charging electrical energy unit(s) to respective winding(s) in charging configuration(s) for a second period of time to be charged with respective induced current(s). | 2017-01-26 |
20170025868 | BATTERY THERMAL MONITORING SYSTEM - A battery thermal monitoring system prevents thermal runaway during battery charging. A temperature sensor and relay may be connected to each battery. The temperature at each battery may be compared to the ambient temperature in the charging system. When the temperature difference between the battery charging temperature and the ambient temperature exceeds a predetermined difference, the relay may disconnect the battery from the charging source. | 2017-01-26 |
