The invention provides a control circuit for intelligent on-off of an automobile storage battery, the control circuit is provided with a single-chip microcomputer module, a power supply module, a comparator module, a boost module and a logic circuit module, intelligent on-off control of the storage battery can be realized, the front end of the single-chip microcomputer module is provided with a DC5V-3. 3V power supply module, the DC5V-3. 3V power supply module is in power supply connection with the single-chip microcomputer module, and the logic circuit module is connected with the single-chip microcomputer module. The front end of the DC5V-3. 3V power supply module is provided with a DC12V-5V power supply module, the DC12V-5V power supply module is in power supply connection with the DC5V-3. 3V power supply module, and the front end of the DC12V-5V power supply module is in electric signal connection with the negative electrode of the power wire harness. The problems that an existing storage battery on an automobile is not provided with a battery on-off control circuit, intelligent on-off of the storage battery cannot be achieved, when the automobile flames out, the storage battery still has high static electricity output loss, the storage battery continuously feeds, and when the automobile is started again, starting is difficult or fire cannot be ignited are solved. The device can be widely applied to intelligent on-off of the automobile storage battery.
本发明提供一种用于汽车蓄电池智能通断的控制电路,其设有单片机模块、供电模块、比较器模块、升压模块、逻辑电路模块,能够实现蓄电池的智能通断控制,单片机模块的前端设有DC5V‑3.3V供电模块,DC5V‑3.3V供电模块与单片机模块供电连接,DC5V‑3.3V供电模块的前端设有DC12V‑5V供电模块,DC12V‑5V供电模块与DC5V‑3.3V供电模块供电连接,DC12V‑5V供电模块的前端与电源线束负极电信号连接。其解决了现有汽车上的蓄电池由于没有设置电池通断控制电路,无法实现蓄电池的智能通断,导致汽车熄火时,蓄电池还存在较高的静电量输出损耗,导致蓄电池持续馈电,当汽车再次启动时,出现启动困难或者打不着火的问题。本发明可广泛应用于汽车蓄电池的智能通断。
