Install a timer circuit on an electric vehicle

Circuit working principle: The integrated block CD4060 is a 14-stage two-frequency serial counter
with its own oscillator. The square wave
oscillator is composed of 9, 10 and 1 pins of 1C and C4, R4 and C. The timing time of the RC parameters shown in Figure 5-5 is approximately 180 minutes. When charging is required
, press the button switch AN, and the 220 V voltage passes through C. After stabilization, a 12 V
DC working voltage is obtained. Month: C3 provides reset voltage to pin 12 , and the CD4060 juice counter starts
to work. At this time, pin 3 outputs low level, VT, is cut off, VT7 is on, relay K
works, and contact K is closed. Closed to form self-locking. The socket cz provides power output for the charger
, and the charger charges the electric vehicle . VDz is a light-emitting diode, and its flashing frequency is
the frequency of the 1C oscillator. After about 180 minutes, pin 3 outputs high level, VT, is turned on,
VT2 is turned off, the relay contact Ko is disconnected, the whole machine is powered off and stops working, and charging is completed.
