Abstract:
A method of operating a rechargeable battery subject to charge control parameters comprising a nickel hydroxide positive electrode and an electrolyte comprising the steps of:(a) after completion of a discharge cycle, charging the battery at a temperature T1 between approximately âˆ’10Â° C. and âˆ’30Â° C. which is lower than a temperature T2, in the range of approximately âˆ’15Â° C. to +5Â° C., at which discharge begins; (b) automatically and without manually tuning the charge control parameters determining a total charge to be returned to the battery for establishing an ideal charge and temperature for the battery leading into the next discharge cycle; and (c) applying charge energy to the battery having the magnitude determined in step (b).
