Abstract

The present disclosure provides a power supply device and a vehicle information system including the same, the device includes: a main power supply unit and a backup power supply unit, wherein the backup power supply unit is connected to the output end of the main power supply unit through a boost unit, and As the output terminal of the power supply device; a boost unit, the boost unit has an enable terminal, and the enable terminal is set to respond to the output voltage of the main power supply unit being higher than the first voltage threshold and / or The output voltage of the standby power supply unit is higher than the second voltage threshold to keep the boost unit in an enabled state, and the boost unit is used to output different voltages according to the source voltage of the main power supply unit. The boost unit is always enabled, so the process of switching from the main power unit to the backup power unit takes a very short time and realizes seamless switching, avoiding the parallel connection of large capacitors at the output end of the power supply unit, reducing costs and improving It improves the reliability of main and backup power switching and power supply.

Description

technical field [0001] The present disclosure relates to the technical field of the Internet of Vehicles system, in particular to a power supply device and a vehicle information system including the same. Background technique [0002] The Internet of Vehicles system includes four parts: the host, the vehicle information system (referred to as vehicle T-BOX, Telematics BOX), the terminal application program and the background server. Among them, the vehicle T-BOX is mainly used to communicate with the background server and the terminal application program to realize the terminal Display and control of vehicle information by application. The vehicle T-BOX is generally powered by the vehicle battery and the backup power supply. Under normal circumstances, the vehicle battery is used for power supply. Once the vehicle battery fails and the power supply is abnormal, it needs to be switched to the backup battery for power supply; switch. Contents of the invention [0003] The ...
