  • Battery charging system and method of using same
    Patent number: 5349281
    Abstract: A battery charging system which prevents false switching from a fast charge mode to a trickle charge mode due to low frequency voltage aberration signals. The battery charging system includes a battery voltage analyzer and a plurality of battery charging and conditioning units for charging different types and kinds of nickel cadmium batteries. Firmware in the microprocessor rejects low frequency aberrations permitting a desired voltage signal to be produced which is indicative of the actual battery potential for charge switching purposes.
    Type: Grant
    Filed: September 28, 1992
    Date of Patent: September 20, 1994
