摘要： A battery charger with a fixed frequency charging signal at or near the resonant frequency of the battery to be charged is presented. The present invention utilizes a microprocessor to modulate a current source at or near the resonant frequency of the battery to be charged without the use of a PLL. To simplify conventional modulated battery chargers, the PLL or other methods of phase correction are removed, reducing most of the calculation requirements for adjusting the phase angle, thereby reducing the piece count and ultimately cost and complexity. The result is a solution wherein charging occurs at or near the resonant frequency of the battery, and although suboptimal, the results are superior to traditional charging methods.

摘要： A method and apparatus for acquiring battery temperature measurements using stereographic thermal imaging sensors or a simple single thermal imaging sensor which can detect increases in battery heat within the field of view of any single thermal sensor, or any combination of a plurality of thermal imaging sensors is presented. Infrared Detection (ID) using the thermal imaging sensor (pyrometer) is used to focus on certain parts of a housing thereby providing an ability to “see through” or “partially see through” the battery housing to battery cells enclosed by the battery housing. Advantageously, this affords the unique capability of measuring the battery temperature before heat propagates from an individual battery cell or a plurality of battery cells to the battery housing, allowing faster heat gradient detection. Moreover, universality of battery temperature monitoring is achieved by elimination of proprietary communication between the manufacturer of the battery and the charger.
