QUICK CHARGING METHOD OF ALKALINE SEALED ACCUMULATORS AND ACCUMULATOR BATTERIES, AND MEASUREMENT METHOD OF INTERNAL TEMPERATURE OF SEALED ACCUMULATOR Russian patent published in 2011 - IPC H01M10/44 H01M10/50 

FIELD: electricity.

SUBSTANCE: charging of accumulators without their overheating and damage is performed with charging current density maximum required during the whole charging process, which allows considerably enlarging the range of moving-up charging currents; at that, charging time of accumulators remains minimum possible for the chosen charging velocity. Factor of charging current reaches 99%. Minimum time of complete charge of accumulators and accumulator batteries is 17 minutes and less. Method is not sensitive to parametre spread of various examples of accumulators. Control of charging process and determination of point of time when the charging is stopped is based on measurement of temperature of charged accumulator. Measurement method of temperature of sealed accumulator allows measuring temperature of its inner layers.

EFFECT: improving accuracy and reducing time constant of measurements.
