Abstract:
In a battery conditioning system,(a) a rechargeable battery to supply operating current during a number of hours of portable operation so as to become progressively discharged as a result,(b) a battery conditioning circuit coupling with said rechargeable battery to supply current to said rechargeable battery during a battery conditioning cycle,(c) said battery conditioning circuit comprising a computer having an input section to receive measures of battery temperature at successive times during such battery conditioning cycle, and(d) a current control coupling with said rechargeable battery to control the rate of current flow to the rechargeable battery during a battery conditioning cycle,(e) said computer having an output section coupled with said current control to vary the rate of current flow to said rechargeable battery during a battery conditioning cycle as a function of battery temperature as monitored by said computer,(f) a current monitor coupled to the battery to monitor any portion of current to the battery during the battery conditioning cycle attributable to a load on the battery;(g) a load control operatively connected between the current monitor and the current control to insure that current flow to said battery during the battery conditioning cycle exceeds current attributable to a load on the battery.
