    • A charging control circuit having a controller including a microcomputer, a charging circuit, detectors for detecting the voltages between the terminals of batteries, and memories for storing charge control data. The controller determines that quick charging is completed when the voltage between the terminals of each battery drops from a peak value to an extent corresponding to a predetermined value stored in the memory, and then terminates the charging operation. During a predetermined period of insensible time immediately after the start of charging stored in the memory, the controller does not detect the voltage to determine whether or not each battery is fully charged, thereby preventing an error in determining a fully charged state of the battery. If a full charge of each battery is not detected while quick charging is continued for a certain period of time stored in the memory, the controller forcibly terminates the quickly charging operation. Desired data is selected from the control data stored in the memories in response to an external signal, and the charge control is optimized according to the number of batteries and other factors.
    • 一种充电控制电路,具有包括微计算机,充电电路,用于检测电池端子之间的电压的检测器和用于存储充电控制数据的存储器的控制器。 当每个电池的端子之间的电压从峰值下降到对应于存储在存储器中的预定值的程度时,控制器确定快速充电完成,然后终止充电操作。 在存储在存储器中的充电开始之后的紧急预定时间内,控制器不检测电压,以确定每个电池是否完全充电,从而防止确定电池的完全充电状态的错误。 如果在存储器中存储一段时间内持续快速充电的情况下未检测到每个电池的完全充电,则控制器强制终止快速充电操作。 根据外部信号从存储在存储器中的控制数据中选择期望的数据,并且根据电池的数量和其他因素来优化充电控制。

    • A battery charger and a charge controller therefor are disclosed, the battery charger including a supply circuit for supplying a charging current to a battery and a control circuit for controlling the supply of the charging current to the battery. The control circuit shuts the charging current when the detected voltage of the battery is smaller than the maximum peak value by a predetermined quantity. A control means shuts the charging current after a predetermined time has elapsed from a time at which the detected voltage of the battery has raised to the maximum peak value. The control means reduces the charging current when the detected voltage of the battery is made to be a switching voltage. Furthermore, the control means shuts the charging current after a predetermined time has elapsed after the charging current had been reduced.
    • 公开了一种电池充电器及其充电控制器,电池充电器包括用于向电池供应充电电流的供电电路和用于控制向电池供应充电电流的控制电路。 当电池的检测电压小于最大峰值预定量时,控制电路关闭充电电流。 在从电池的检测电压上升到最大峰值的时间经过了规定时间后,控制装置关闭充电电流。 当电池的检测电压为开关电压时,控制装置减小充电电流。 此外,控制装置在充电电流减小之后经过了预定时间后关闭充电电流。
