    • A power supply arrangement for supplying power from a battery (2) to an electric load (3) comprises a controlled switch (4) having a first state in which a connection is provided from the battery (2) to the load (3), and a second state in which the load (3) is disconnected from the battery (2), and a control circuit (5, 8, 9) for controlling the state of the controlled switch (4). The control circuit (5, 8, 9) is arranged to be disconnected from the battery (2) when the controlled switch (4) is in its second state. By disconnecting not only the electrical load, but also the control circuit from the battery, it is ensured that this circuit cannot draw any leakage current from the battery, when the load is switched off. This means that no over-discharge protection is needed in the battery itself.
    • 用于从电池(2)向电负载(3)供电的电源装置包括:具有第一状态的受控开关(4),其中从电池(2)向负载(3)提供连接, 以及负载(3)与电池(2)断开的第二状态,以及用于控制受控开关(4)的状态的控制电路(5,8,9)。 控制电路(5,8,9)被布置成当受控开关(4)处于其第二状态时与电池(2)断开连接。 通过不仅断开电气负载,而且断开来自电池的控制电路,当负载关闭时,确保该电路不会从电池中吸取任何泄漏电流。 这意味着电池本身不需要过放电保护。

    • The present invention relates to an apparatus and method for charging a battery cell according to a charging scheme. The apparatus comprises a power supply and control unit for delivering a charging current to the battery cell according to said scheme, a current monitoring device for monitoring and measuring the charging current, a voltage monitoring device for monitoring and measuring the voltage over the battery cell, a charging terminator devised for terminating the charging of the battery when a predetermined charging criteria is met and a safety timer for starting a predetermined time interval when charging of the battery cell has reached its constant voltage. The predetermined charging criteria is met either when the charging current is falling below a predetermined limit or when the charging current has not decreased a predetermined amount, ΔI, within the predetermined time interval.
    • 本发明涉及一种根据充电方案为电池单体充电的装置和方法。 该装置包括用于根据所述方案向电池单元传送充电电流的电源和控制单元,用于监视和测量充电电流的电流监视装置,用于监视和测量电池单元上的电压的电压监视装置, 设计用于在满足预定的充电标准时终止电池的充电的充电终止器,以及当电池单元的充电已经达到其恒定电压时用于开始预定时间间隔的安全定时器。 当充电电流下降到预定极限以下或当充电电流在预定时间间隔内没有减小预定量时,满足预定充电标准。
