The invention discloses an automobile starting power supply with a
voltage detection function. The automobile starting power supply with the
voltage detection function comprises an MCU, a temperature detection circuit, an overload protection circuit, an automobile
voltage detection circuit, an undervoltage protection circuit, a 12V power supply and a drive circuit. The MCU is connected with an anti-
reverse connection detection circuit, an anti-
short circuit detection circuit, an
overvoltage protection circuit, a temperature detection circuit, the overload protection circuit, the automobile voltage detection circuit, an LCD drive circuit, a power circuit, a timing module and the drive circuit, and the drive circuit is also connected with a
power output, the 12V power supply and the timing module. The automobile starting power supply with the voltage detection function can directly measure the voltage of an storage battery at the automobile end and display the voltage on an LCD screen, intuitive data are provided for users, so that users can quickly judge whether the undervoltage of the storage battery leads to the fact that the automobile can not be started by taking the data as a reference; and the comprehensive fault detection and promoting function is fulfilled, safe
usage experience is provided for users, and unwanted accidents are avoided.
