Abstract
In an overdischarge detection device which is connected between positive and negative load current lines for connecting a chargeable electric cell with a load and which comprises an overdischarge detection circuit including a voltage comparing section for detecting that a cell voltage of the electric cell falls below a threshold voltage to prohibit discharging operation, an adjusting circuit connected to the overdischarge detection circuit detects a particular voltage of a specified part that corresponds to a load current varying in response to relative weight of the load to adjust the threshold voltage on the basis of the particular voltage. Preferably, the adjusting circuit may be constructed so as to clamp the threshold voltage when the particular voltage is higher than a predetermined voltage.
