摘要： Disclosed are methods for charging batteries utilizing a charge balance approach, and charger systems using those methods. In one example, a method for charging a battery includes monitoring an amount of charge released by the battery while in a discharge state, recording the amount of charge released while in the discharge state, applying a voltage which results in current in reverse direction to the battery at a first voltage level for a time sufficient to introduce an amount of charge substantially equal to the recorded amount of charge released by the battery while in the discharge state, and maintaining the battery in a stand-by mode by applying a voltage which results in current in reverse direction to the battery at a second voltage level, the second voltage level being in a range sufficient to prevent self-discharge of the battery and insufficient to induce evaporation of electrolyte in the battery.

摘要： The present invention relates to emergency lighting ballasts having rechargeable batteries, usually of the nickel-cadmium type and more specifically to an apparatus to facilitate the charging of the battery pack at temperatures generally below normal operating ranges of the batteries (such as below 0° C) without damaging the battery. The apparatus includes such as a reverse-biased zener diode which has a breakdown voltage in the reverse mode which is at or below the maximum allowable charging voltage for the battery. Accordingly, when ambient conditions would otherwise allow the charging current of the battery to exceed the allowable level, the clamping zener diode breaks down shunting the excess current away from the battery.
