  • Patent number: 7696729
    Abstract: A plurality of supercapacitor elements is arranged in rows and columns within a single housing. The elements have no physical connection until they are configured into series, parallel or combinatory matrix by a configuration circuit composing of switches, a driver and a controller. Under the manipulation of the configuration circuit, the elements can be assembled in a broad voltage range to deliver the desired powers to automobiles, heavy machineries, power tools, appliances, or consumer electronics in real-time responses. When the loads present energy for recovery, the elements can also be immediately grouped in the voltage and capacity ranges corresponding to the power levels of the energy to be harvested. Using the present invention, the efficiency of DC and AC energy utilization can be significantly improved.

  • Publication number: 20080129253
    Abstract: An energy-reclamation apparatus of the present invention including at least a supercapacitor element connected with a charging source and a controlled circuit. After the supercapacitor element is charged to the potential of the charging source, the supercapacitor element and the charging source will work in series to conduct a repetitive polarity reversal of the supercapacitor element through a controlled circuit. As the supercapacitor element discharges, it is reversely charged concurrently. In other words, while the voltage of the supercapacitor element is decreasing on the side, a negative potential is complementarily developing on the other side. By repeatedly reversing the polarity of the supercapacitor element, more energy from the serially connected charging source can be reclaimed and reused.
