    • Current flowing into and out of a battery installed in a vehicle (V) with the required cable between one of the battery terminals and a reference point on the vehicle is determined by measuring the voltage across the cable and computing the current from the digital value of the measured current. The resistance value of the cable can be known in which case the current is computed using Ohms law and a differential current sensor can be used to respond to the voltage measured across the cable to accommodate for different ranges of current. In an embodiment where the cable resistance is unknown, a reference current source produces a known voltage that is used to set the input value to an amplifier of fixed gain for the voltage measured across the cable by controlling the output of a potentiometer so that the amplifier output voltage can be set to match the reference current generator output voltage, thereby establishing the voltage output of the amplifier as a measurement of the current flow in the cable.

    • Apparatus and method for automatic recovery of sulfated lead acid batteries rely on monitoring battery voltage, current and internal resistance during battery charging. The lead acid battery is recovered for usage by measuring the internal resistance to see if it is so high such that the battery is unrecoverable, or so low such that the normal charging methods can be used. If the internal resistance is between the two limits, the battery receives a first constant charge current. As the lead acid battery is being charged slowly by a constant charge current, the battery voltage is measured. The decrease in the internal resistance (IR) of the battery causes the battery voltage to decrease during charging, while the charging causes the battery voltage to increase. According to the present invention, if it is detected that the battery voltage has reached the minimum voltage and begun to increase in a predetermined period of time, the charge current is substantially increased (e.g., doubled) because the capability of the lead acid battery to accept a higher charge current has increased. As the charge current is increased, the recovery and charging of the lead acid battery arc advantageously more expedient and efficient.
    • 硫酸铅酸电池的自动回收装置和方法依靠电池充电期间的电池电压,电流和内部电阻的监测。 铅酸电池通过测量内部电阻来恢复使用,以观察其是否如此高,使得电池不可恢复,或者如此低,使得可以使用正常的充电方法。 如果内部电阻在两个极限之间,电池将接收第一个恒定的充电电流。 由于铅酸电池通过恒定的充电电流被缓慢充电,所以测量电池电压。 电池内部电阻(IR)的降低导致充电期间电池电压降低,而充电会导致电池电压升高。 根据本发明,如果检测到电池电压已经达到最小电压并且在预定时间段内开始增加,则充电电流显着增加(例如,加倍),因为铅酸电池的能力 接受较高的充电电流已经增加。 随着充电电流的增加,铅酸蓄电池的恢复和充电有利地更方便和有效。
