Networking control-based vehicle-mounted charging system

Abstract

A networking control-based vehicle-mounted charging system comprises a CPU (central processing unit), a communication circuit, a power supply circuit, a switching circuit and a plurality of charging terminals, the charging terminals are connected in parallel with the power supply circuit, the communication circuit is connected in series with the charging terminals and the CPU, and the CPU controls the connection between the power supply circuit and a vehicle-mounted power supply through the switching circuit. Each charging terminal comprises an MCU (microprogrammed control unit), a DC-DC (direct current-direct current) switching circuit and a protective circuit, the MCU is connected with the control end of the DC-DC switching circuit and the communication circuit, the input end of the DC-DC switching circuit is connected with the power supply circuit through the protective circuit, and the output end of the DC-DC switching circuit is connected with a charging interface. By adopting the technical scheme, the system can simultaneously charge a plurality of mobile devices, is suitable for large public transportation equipment with a lot of passengers, has a centralized control function, and can be further added with a charging function for charging.

Description

technical field

[0001] The invention relates to an on-vehicle charging system, in particular to an on-vehicle charging system based on networking control. Background technique

[0002] A common car charger is composed of a protection circuit and a charging chip. The interface generally uses a cigarette lighter port, and the other side is a USB charging interface. This kind of car charger can only charge one device at a time. It is mainly suitable for scenes with a small number of passengers such as cars, and is not suitable for public transportation equipment with a large number of passengers. Contents of the invention

[0003] The purpose of the invention is to design a vehicle charging system based on networking control for the current situation that the public transportation system cannot charge multiple mobile handheld devices. The charging system can provide charging services for multiple devices at the same time. The specific technical solution yes:
