Patent ID: 8558511

Claim:
A method for managing charging and discharging of a battery comprising the steps of: a. connecting said battery to a battery charger, b. connecting the battery charger to a power supply, c. providing a plurality of controllers in communication with one and another, each of said controllers monitoring input variables, and an input variable monitored by one of the controllers is indicative of a condition of electrical power of the power supply and an input variable monitored by another of the controllers is rate of change of measured battery pressure, d. generating a set of charging constraints for each controller as a function of the input variables monitored by that controller and wherein the set of charging constraints for the another of the controllers includes the rate of change of measured battery pressure, e. defining an actual charge rate falling within all of the sets of charging constraints generated for the plurality of controllers including limiting the actual charge rate using the rate of change of measured battery pressure, f. providing a current flow between said battery and said battery charger at the actual charge rate.
