International Classification:

H02J 7/00

US Classification:

320155, 320139

Abstract:

A battery charger with a self-contained power source which provides a current charging signal at or near the resonant frequency of the battery to be charged when no other power supply is readily available. A storage energy device, for example a battery, delivers a current charging signal modulated at or near the resonant frequency of a load, or stores energy from a source.

Assignee:

Advanced Battery Management, LLC - Irving TX

International Classification:

H02J 7/00

US Classification:

320137

Abstract:

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.

Inventors:

International Classification:

H02J 7/00

US Classification:

320150

Abstract:

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.

International Classification:

H02J 7/00

US Classification:

320106

Abstract:

A signature connector adapter adapted to provide additional capabilities for a battery charger beyond not only charge batteries, but performing other user-friendly functions is presented. One embodiment utilizes a resistor disposed within a signature charger adapter to detect battery type and communicate the battery type to the battery charger. The signature connector adapter provides information such as, but not limited to, battery chemistry, battery voltage, charging capabilities, and thermal limits. The battery charger can then optimize charging performance. The signature connector adapter allows a plurality of household, construction, medical and military devices to be charged and/or powered via the battery charger. Devices such as lights, radios, cigarette lighters, and other such devices requiring specific levels or types of power can now be operated and charged with a single charger, since the signature connector adapter facilitates the charging system changing its output to match the device's requirements.

Assignee:

Ericsson, Inc. - Research Triangle Park NC

International Classification:

H02M 7217
H02M 100

US Classification:

363127

Abstract:

A rectifier circuit having voltage clamping circuitry is disclosed. The rectifier circuit includes a transformer having a primary winding and a secondary winding and transistor switches each being connected to an end of the secondary winding of the transformer. The rectifier circuit further includes a first diode having an anode terminal connected to a first end of the secondary winding and a second diode having an anode terminal connected to a second end of the secondary winding. The cathode terminals of the first and second diodes are coupled to a capacitor. The energy stemming from voltage spikes and/or high frequency ringing appearing at the transistor switches due to parasitic effects is effectively absorbed by the first and second diodes and collected in the capacitor. The collected energy is recycled to control the operation of the transistor switches.
