  • Battery charging control circuits
    Patent number: 3936718
    Abstract: An improvement in the battery charging control circuit of our co-pending Application Serial No. 400,001, and more particularly a new means for detecting the onset of gassing during the charging of a battery, such as lead-acid battery.In the exemplary embodiment described in our co-pending Application Serial No. 400,001, the onset of gassing was assumed to be imminent upon the attainment of a particular battery cell voltage. The present invention provides an improved means for determining the true onset of gassing by recognition of a unique point in the temporal pattern of the differences between successive registered battery voltages as measured during interruptions of charging.
