    • In an apparatus, a predicting unit uses, as an initial value of a controlled variable, at least one of a first measured value of the controlled variable and a second measured value of a physical variable expressed as a function of the controlled variable. The predicting unit predicts, based on the initial value of the controlled variable, a value of the controlled variable when a driving mode of a switching element of a power converter is set. A driving unit has an integral element and determines, based on an output of the integral element to which a deviation between the predicted value of the controlled variable and a command value of the controlled variable is inputted, an actual driving mode of the switching element to thereby drive the switching element in the determined driving mode.

    • A large number of rechargeable unit cells connected in series forming a combination battery are divided into groups of cells, each group including several cells, preferably, three to five cells. Voltage unevenness among the cells in each group is eliminated by operation of a voltage balancer device connected to each group of cells. The voltage balancer device includes a circuit for equally dividing a terminal voltage of the group of cells and obtaining an average voltage among the cells. The average voltage is compared with an individual cell voltage, and the cells having a voltage higher than the average voltage are discharged so that all cell voltages in the group become equal. A plurality of the battery modules each including the group of cells and the voltage balancer device are connected in series to form a single combination battery, and voltage unevenness among the battery modules are controlled by another voltage control device. The voltage unevenness among cells in a group may be eliminated by charging a capacitor from cells having a higher voltage and charging cells having a lower voltage from the charged capacitor. Thus, the voltage unevenness among the combination battery cells is eliminated by a simple and inexpensive device.
    • 串联连接形成组合电池的大量可再充电电池单元被分成一组电池,每个组包括几个电池,优选三个至五个电池。 通过连接到每组电池的电压平衡装置的操作来消除每组中的电池之间的电压不均匀性。 电压平衡器装置包括用于对该组单元的端子电压进行均分并获得单元之间的平均电压的电路。 将平均电压与单个电池电压进行比较,并且将具有高于平均电压的电压的电池放电,使得组中的所有电池电压相等。 每个包括电池组和电压平衡器装置的多个电池模块串联连接以形成单个组合电池,并且电池模块之间的电压不均匀性由另一个电压控制装置控制。 通过从具有较高电压的电池充电电容器和来自充电的电容器的具有较低电压的充电电池,可以消除组中的电池之间的电压不均匀性。 因此,通过简单且便宜的装置来消除组合电池之间的电压不均匀性。
