Abstract
The present inventions, in certain aspects, are directed to techniques and/or circuitry to charge a battery the method comprises (i) charging the battery via a charging sequence, wherein charging the battery includes: (a) applying a plurality of charge signals, and (b) applying one or more discharge signals wherein, in response thereto, the battery outputs electrical energy. In certain embodiments, the electrical energy output by the battery in response to the discharge signals is stored (for example, in a capacitor and/or second battery). The present inventions are also directed to, among other things, an apparatus to charge a battery comprising charging circuitry including: (i) a current source to generate a plurality of charge signals, and (ii) a current sink to generate one or more discharge signals, wherein, in response thereto, the battery outputs electrical energy. The apparatus may also include control circuitry, a storage device (for example, in a capacitor and/or second battery), to store the energy output by the battery in response to the one or more discharge signals, and/or an ambient environmental device to adjust the ambient environment or conditions of the battery u…
