Abstract

The invention relates to a voltage judging device for an electrical automobile charging control guidance system. The voltage judging device is composed of a main control unit, a threshold value generating module, a voltage comparison module, a voltage conversion module and an Ethernet interface module, wherein the main control unit is in one-way connection with the voltage conversion module and in two-way connection with the Ethernet interface module, the threshold value generating module is in one-way connection with the voltage comparison module, and the voltage comparison module is in one-way connection with the voltage conversion module. The main control unit is in two-way connection with a charging control guidance module, and the charging control guidance module is in one-way connection with the voltage comparison module and an electric automobile charger. The voltage judging device provided by the invention has such two charging modes that a background monitoring system regulates the output power of a vehicle-mounted charger and the background monitoring system does not regulate the output power of the vehicle-mounted charger, provides a reliable and practical voltage judging device for judging the charging connection state of the electric automobile, and prevents misplug of a charging interface of the electric automobile.

Description

technical field [0001] The invention relates to a voltage judging device of an electric vehicle charging control and guidance system, which belongs to the field of communication control. Background technique [0002] The charging interface is a device that connects the active cable in the charging device and the electric vehicle, and charges the electric vehicle by means of electrical conduction. The electric vehicle charging control and guidance system is the part that realizes the communication connection between the charging device socket and the electric vehicle charging interface. The device is currently available for the maximum continuous current rating to adjust the electric vehicle charger output power. The existing electric vehicle charging guidance system adopts a single charging mode that adjusts the output power of the on-board charger, without considering the sufficient power supply of the power supply equipment and the fact that the on-board charger does not ...
