    摘要： A four-stage charging technique for nickel-zinc cells and batteries, is provided, whereby a high cycle life is assured, without dendrite formation or harmful overcharge, with minimal shape change of the zinc electrode, and with minimal oxygen recombination. In the first stage, the nickel-zinc cell or battery is charged with an average current less than C/5 for a period of less than five minutes, or until the terminal voltage of a cell reaches 1.75 volts to 1.79 volts. In the second stage, a fast charge is imposed, until the terminal voltage of a cell reaches between 1.88 volts and 1.92 volts. In the third stage, a moderate charge is imposed, until the terminal voltage of a cell reaches 1.90 volts to 1.94 volts. The fourth stage gives a trickle charge when the terminal voltage is greater than 1.94 volts. Typically, each of the transitions between the Stages 1 and 2 and Stages 2 and 3 is determined by a temperature dependent voltage; the transition between Stages 3 and 4 is determined by a time dependent inflection point of the terminal voltage of the cell; and Stage 4 termination is determined when dV/dt = 0.

    摘要： The present invention provides a method for detecting a fully charged condition of a secondary battery by which the fully charged condition of a secondary battery can be detected accurately and deterioration in battery characteristic due to overcharging can be restrained irrespective of the charging mode and the surroundings, without the need for a special battery structure. In the method, pulse vibrations generated inside a secondary battery being charged are detected, and when the obtained characteristic value of the pulse vibrations, for example, incidence of generation of the vibrations reaches a predetermined value, the secondary battery is determined to be in fully charged condition.

    摘要： The useful life of an electrolytic battery cell commonly employed in a series string (17) as a backup power source is significantly extended by maintaining the polarization of the positive plates (22) of such a cell at a predetermined level relative to a reference electrode (26) of similar composition in contact with the cell electrolyte. While the cell is being supplied with the usual float charging voltage, a controller circuit (20) senses any variance of polarization below the desired level and meters a minute input current to the positive plates with a resulting increase in the polarization over a substantial time period. The slow biasing of the polarization effects a passivation of the surface of the plates which deters the penetration of oxygen to the plate metal and prevents the deep destructive formation of expansive metal oxide.

    摘要： A charging voltage or an overcharge determination value for determining an overcharge state is set taking into consideration the states of secondary battery cells (21a-21d) of a battery pack (20) during charging. Charging of the secondary battery cells is then carried out using charging voltages set taking into consideration the states of the secondary battery cells. It is then determined whether or not the secondary battery cells are in an overcharged state using overcharge determination value is set taking into consideration the states of the secondary battery cells.
