The present disclosure relates to a field-effect transistor (FET) controlling apparatus and method for accurately, controlling an operation state of a FET by adaptively adjusting a voltage applied to the FET to correspond to a voltage of a source terminal of the FET. The voltage applied to the gate terminal of the FET may be adaptively controlled according to the voltage of the source terminal using a capacitor. Therefore, even when the source terminal is not connected to the ground but connected to an external load, there is an advantage that the operation state of the FET may be smoothly and accurately controlled. In addition, there is an advantage that a voltage within a certain range may be applied to the gate terminal of the FET.

FET controlling apparatus and method

A battery control system includes first to third signal paths, and first to nbattery controllers. When a high level voltage is inputted through the second signal path, the first battery controller sets an ID of the first battery controller based on ID information collected through the first signal path and outputs the high level voltage to the second signal path. Where i is a natural number of 2˜n, when the high level voltage outputted by the i−1battery controller is inputted through the second signal path, the ibattery controller sets an ID of the ibattery controller and outputs the high level voltage to the second signal path. When the high level voltage is outputted to the third signal path by the nbattery controller, each battery controller outputs a response signal to the first signal path.

Disclosed is an apparatus and method for controlling power of a parallel multi pack system. The power control apparatus includes first to nsensor units measuring operation characteristic values of first to nbattery packs connected in parallel; a power management unit controlling a power consumed in a load or a power provided by a charging device; and a multi pack management unit that: determines a pack resistance of each of the battery packs based on the operation characteristic value of each battery pack received from the sensor units, determines a minimum available power among available powers respectively corresponding to the pack resistances of the battery packs, determines a total power of the parallel multi pack system so the pack power of a battery pack having a lowest pack resistance becomes identical to the minimum available power, and transmit the determined total power to the power management unit.
