Abstract

An over-discharge prevention apparatus comprising: PA1 a voltage detection device 2 for detecting electric voltages of both ends of a electric storage element (B) and outputting a discharge finishing signal (PFD) when a discharge extinction voltage (VL) is detected; PA1 a discharge controlling device 3 for delaying the detected output of the voltage detection device 2 for a predetermined time (Td); and PA1 a switching device 1 connected in series with the electric storage element (B), the switching device being set to an OFF state by a delay signal of the discharge controlling device.
