1. Apparatus for monitoring and forecasting performance of a system of connected batteries, comprising:

  • a. a plurality of probe assemblies connected for sensing physical parameters indicative of the operating states of said connected batteries, said probe assemblies having an output means providing digital output signals indicative of said sensed physical parameters;

    b. means for generating digital data strings and providing said strings to said probe assemblies;

    c. means associated with said probe assemblies for modifying the digital data strings applied to said probe assemblies to reflect present values of said sensed physical parameters;

    d. means for sensing resulting output voltage and current of said connected batteries;

    e. means for providing historical data battery output voltage and current as functions of said physical parameters;

    f. means receiving said sensed output voltage and current of said connected batteries for processing said digital data strings to obtain real time values indicative of operating parameters of individual ones of said connected batteries when said parameters are sensed; and

    g. means for comparing said values to fixed parameter values and determining corresponding battery performance from said stored historical data;

    wherein said probe assemblies are serially connected.
