  • Charging regulator
    Patent number: 4614905
    Abstract: An autonomous regulator for regulating the charging current to the individual cells in a battery. The regulator shunts the portion of the trickle current which constitutes an excess to the charging current. There is thus provided an optimum charge for each cell, independent of differences in self-discharge of the different cells. The size of the shunted current is determined by the difference between the cell pole voltage and a reference voltage generated in the regulator.

  • Method and apparatus for rapid battery charging
    Patent number: 4179648
    Abstract: A method and apparatus for charging electrical storage batteries having a known nominal amperage. Discharging the battery to a predetermined value and then charging the battery with a charging current which is initially several times greater than the nominal battery amperage and which charging current decreases exponentially from the initial charging current to a charging current which is much less than the nominal battery amperage when the battery is fully charged. The apparatus uses the discharge rate of an RC circuit to exponentially control the charging current applied to the battery.
