The invention discloses a power supply starting circuit. The power supply starting circuit comprises a microcontroller, a voltage detection circuit, an internal resistance detection circuit and a controllable switch circuit, and when an automobile storage battery is installed in an automobile, the power supply starting circuit can detect the internal resistance of the automobile storage battery, the electricity quantity of the storage battery and the health condition of the storage battery; besides, the microcontroller can control a switch circuit to be connected to make an automobile energy storage element output starting current to start the automobile. Thus, the power supply starting circuit has the functions of starting the automobile and detecting the parameters of the automobile storage battery so that when the automobile storage battery cannot provide starting current, the power supply starting circuit can detect the related parameters of the automobile storage battery while providing starting current, the fault of the automobile storage battery is detected, and then the problems that in existing manual fault investigation, much time and labor are consumed, and the investigation efficiency is low are solved.
Description
technical field [0001] The invention relates to the technical field of automobiles, and more specifically relates to a starting power supply circuit. Background technique [0002] The car battery, also known as the car battery, can provide a strong starting current to the engine when the vehicle starts the engine. When the car battery is unable to provide the starting current for the vehicle due to some reasons, the car starting power supply will replace the car battery to start and ignite the car. [0003] There are many reasons why the car battery cannot provide the starting current for the vehicle. For example, the car battery is insufficient, the health of the car battery has problems, etc. In the prior art, relevant maintenance personnel are generally required to check the cause of the car battery failure. Time-consuming and labor-intensive, the investigation efficiency is low. Contents of the invention [0004] In view of this, the present invention discloses a sta...
