Battery on/off sensing control device for auto temperature controller of car

The present invention relates to the vehicle's thermostatic appointed taljangchak battery detection control device, a battery mounting portion 10, the battery is mounted; Regulator 20 for regulating the voltage of the 12 volt direct current of the battery 5 volts; The regulator 20, the voltage drop across the current control input port 31 is receiving the provided in the microcomputer (30); Wherein after the microcomputer 30 it is activated a certain time after to so that the receiving is a part of the voltage applied to the microcomputer 30, the voltage change animation to the input port 31 of the microcomputer 30, the microcomputer 30 is first thyristors that allows you to detect the battery facts (40); And it is configured to include a cut-off means such that the breaking operation of the microcomputer 30 is activated a certain time after the time the thyristor (40) of. Thus, after by making adding a transistor to the parallel circuit of the thyristor and the operation of the certain time after the thyristor block in the microcomputer activation time, the battery voltage is first applied and then on the ignition in the initial beginning of the mounting the battery on the battery mount when taljangchak and to distinguish the taljangchak from the ignition-off state to obtain the effects of being able to prevent the leakage current.
