摘要： A circuit for charging a storage battery is disclosed which uses a ferroresonant transformer in combination with a full-wave rectifier to supply direct current to charge the battery. The charging current is controlled by a single silicon controlled rectifier connected to substantially short circuit either all or a portion of one secondary winding of the transformer during increasing portions of half cycles of one polarity as the battery becomes charged. A voltage divider applies a preselected portion of the alternating current transformer output voltage, which is essentially the battery voltage, to gate the controlled rectifier. This preselected voltage is modified by the resistance varying characteristics of a thermistor which is responsive to heat produced by current through the controlled rectifier when it is conducting to reduce the current supplied to the battery. A lamp may be provided to visually indicate when the battery is charged.

摘要： To reduce the charging current in the latter part of a charge, an automatic battery-charging apparatus includes means for comparing a sample voltage depending on the battery voltage while on charge, with a reference voltage which is progressively increased throughout the charge, and using a function of the difference to control the charging current. Thus if the battery voltage and sample voltage increase more rapidly than the reference voltage, the charging current is reduced and vice versa. The reference voltage may be supplied by a motor-driven potentiometer, or by a progressivley charged capacitor. The duration of the charge is also controlled so that a phase of the charge is terminated when the value or rate of change of the sample voltage, having exceeded that of the reference voltage, then falls below it.
摘要翻译：为了减少充电后期的充电电流，自动电池充电装置包括用于在充电时将取决于电池电压的采样电压与在整个充电期间逐渐增加的参考电压进行比较的装置，并且使用功能的差异来控制充电电流。因此，如果电池电压和采样电压比参考电压更快地增加，则充电电流减小，反之亦然。参考电压可以由电机驱动的电位器或由进给电荷的电容器提供。还控制充电的持续时间，使得当已经超过参考电压的样品电压的值或变化速率降到其下面时，电荷的相位终止。
