1. A system for determining the operating characteristics of a battery, said system comprising:

  • active controller means for generating and shaping a time-varying current signal which is adjustable over time for application to said battery wherein said controller means adjusts the shape of said time varying signal based on the operating characteristics of said battery;

    conversion means for receiving from said battery a time-varying return voltage signal and for converting said time-varying return voltage signal into a digital signal, the amplitude of said time-varying return voltage signal being representative of the operating characteristics of said battery, said time-varying return voltage signal being produced in response to said time-varying voltage signal;

    said controller means being responsive to said digital signal for determining the operating characteristics of said battery, said controller means generating display signals representative of the operating characteristics of said battery; and

    display means coupled to said controller means for displaying a result represented by said display signals.
