Abstract: A battery charger is equipped with a current adjusting device. A current sensor continuously measures the current output from the charger and feeds the readings to a current comparator. The terminal voltage of the battery is also continuously read and the readings are fed to a voltage comparator. A voltage reference feeds a constant reference voltage to the voltage comparator. The voltage comparator compares the battery voltage with the reference voltage and feeds a signal dependent upon the voltage difference and in accordance with a preselected program to a current reference. The current reference delivers a signal dependent on the output of the voltage comparator and in accordance with a preselected program to the current comparator. The current comparator to the the signal received from the current sensor tothe signal received from the current reference and provides an output signal to cause the current adjusting device to adjust the charging current to the values called for by the preselected program. A typical charge program which can be selected is a first charging mode at the initial charge rate of the battery until the battery voltage rises to a preselected value slightly below the gassing voltage. This is followed by a second charging mode wherein the charging current is gradually diminished so as to hold the voltage constant at the preselected value. When the charging current drops down to the finishing rate of the battery, a third mode commences wherein the current is held at the finishing rate regardless of further increase of the battery voltage. The charge can be terminated by a timing device set for total charge time or alternately for a predetermined charge period at the finishing rate.

Abstract translation: 电池充电器配有电流调节装置。 电流传感器连续测量来自充电器的电流输出，并将读数馈送到电流比较器。 电池的端子电压也被连续读取，读数被馈送到电压比较器。 电压参考电压将恒定的参考电压馈送到电压比较器。 电压比较器将电池电压与参考电压进行比较，并将取决于电压差并根据预选程序的信号馈送到电流基准。 电流参考值根据电压比较器的输出并根据当前比较器的预选程序提供信号。 电流比较器将信号从当前传感器接收到从当前参考信号接收的信号，并提供一个输出信号，使电流调节装置将充电电流调节到预选程序所要求的值。 可以选择的典型的充电程序是电池的初始充电速率的第一充电模式，直到电池电压上升到略低于放气电压的预选值。 之后是第二充电模式，其中充电电流逐渐减小，以将电压保持在预选值。 当充电电流下降到电池的完成速率时，开始第三种模式，其中电流保持在完成速率，而不管电池电压的进一步增加。 可以通过设定为总充电时间的定时装置或者以完成速率交替进行预定的充电期间来终止充电。
