    • A charger for charging a rechargeable battery. The charger comprises a circuit for producing a charging current having a variable level and a control circuit for controlling the charging current. During a first charging period the current is maintained at a level to rapidly charge the battery at a rate in amperes which is greater than the capacity of the battery in ampere-hours. The controller includes means for interrupting the charging current for a predetermined interruption interval. During the interruption interval, the charging current is maintained at a non-zero value. The controller also includes means for determining a resistance free voltage for the battery. During a subsequent charging period, the charging current is controlled in response to the value of the resistance free voltage.
    • 充电器为充电电池充电。 充电器包括用于产生具有可变电平的充电电流的电路和用于控制充电电流的控制电路。 在第一充电周期期间,电流保持在电平上以使电池快速充电,电池的安培速率大于电池的安培时间。 控制器包括用于在预定的中断间隔中断充电电流的装置。 在中断间隔期间,充电电流保持在非零值。 控制器还包括用于确定电池的无电阻电压的装置。 在随后的充电期间,响应于电阻自由电压的值来控制充电电流。
