Problems solved by technology
However, after the vehicle power supply is connected to the electrical equipment, the battery it carries will continue to discharge, resulting in an increase in the number of charge and discharge times of the battery and a shortened service life of the battery.
[0003] Whether it is the shortening of the battery life or other abnormal conditions of the battery, it will bring inconvenience to the driver, and in more serious cases, it will even endanger the safety of the driver.

The present invention provides a vehicle power supply monitoring device, including an MCU module, a Bluetooth device and a supply voltage monitoring circuit, wherein the first output end of a vehiclepower supply is electrically connected to the input end of the supply voltage monitoring circuit; the output end of the supply voltage monitoring circuit is electrically connected to the MCU module; the second output end of the vehicle power supply is electrically connected to the MCU module and the Bluetooth device to supply power to the MCU module and the Bluetooth device; the supply voltage monitoring circuit, when in operation, monitors the output voltage of the vehicle power supply by the supply voltage monitoring circuit; and when monitoring that the output voltage of the vehicle power supply is abnormal, the MCU module sends out the abnormal information by the Bluetooth device. The vehicle power supply monitoring device is connected to the vehicle power supply so as to monitor the state of the vehicle power supply in real time without an excessive load increase. The vehicle power supply monitoring device is simple in structure and is safe and reliable in operation.
Description
technical field [0001] The invention relates to the field of motor vehicle state monitoring, in particular to a vehicle-mounted power supply monitoring device. Background technique [0002] With the development of society, motor vehicles have become more and more popular. Family cars, as a current mainstream motor vehicle, have more and more appeared in every ordinary family. Vehicle-mounted power supply (mainly storage battery) is a necessary equipment for ignition and starting of cars. However, with the advancement of electronic technology, it has become a development trend to configure electronic accessories on vehicles (such as automobiles, electric vehicles, etc.). Common electronic accessory devices include driving computer, driving recorder and so on. These electronic accessory devices all belong to electrical equipment, and an on-board power supply is usually provided on the vehicle to supply power. However, after the vehicle-mounted power supply is connected to t...
