    • A battery-capacity management device comprises a charged/discharged-capacity integrating unit that detects a voltage and a current of a driving battery and that calculates a discharged capacity of the driving battery. The device also comprises a battery temperature sensor that detects a temperature of the driving battery, a memory, and an available-capacity calculating unit. Map data that represents relationships among voltages, currents, and temperatures of the driving battery at states in which remaining capacity of the driving battery has reached a preset value can be stored in the memory. The available-capacity calculating unit calculates a renewed available capacity of the driving battery based on a discharge capacity discharged over a period between a time when the driving battery is charged and a time when the voltage value detected by the charged/discharged-capacity integrating unit reaches a voltage value corresponding to the current value and the battery temperature in the map data.
    • 电池容量管理装置包括充电/放电容量积分单元,其检测驱动电池的电压和电流,并计算驱动电池的放电容量。 该装置还包括电池温度传感器,其检测驱动电池的温度,存储器和可用容量计算单元。 在驱动电池的剩余容量达到预定值的状态下,表示驱动电池的电压,电流和温度之间的关系的映射数据可以存储在存储器中。 可用容量计算单元基于在驱动电池被充电的时间和由充电/放电容量积分单元检测的电压值之间的时间段期间放电的放电容量来计算驱动电池的更新的可用容量 达到与地图数据中的当前值和电池温度对应的电压值。

    • A drain resistor is connected to a drain electrode of a Field Effect Transistor (FET). One of the input signals to be multiplied is applied to the drain electrode through the drain resistor. The other input signal to be multiplied is applied to a gate electrode of the FET. An output proportional to the product of two signals appears across a resistor connected between a source electrode of FET and ground. In such an arrangement the resistance value of the drain resistor is so determined that the gradient of the characteristics of the drain current to the one input signal becomes almost equal to that of the characteristics of the drain current to the other input signal.
    • 漏极电阻连接到场效应晶体管(FET)的漏电极。 通过漏极电阻将要乘以的输入信号中的一个施加到漏电极。 要乘以的另一个输入信号被施加到FET的栅电极。 与两个信号的乘积成比例的输出出现在连接在FET的源极和地之间的电阻上。 在这种布置中,漏极电阻器的电阻值被确定为对于一个输入信号的漏极电流的特性梯度几乎等于对另一个输入信号的漏极电流特性的梯度。
