Monitoring system of one-machine four-pile charging pile system

Abstract

The invention discloses a monitoring system of a one-machine four-pile charging pile system, and belongs to the technical field of charging pile monitoring. The monitoring system comprises a fault monitoring module, a signal conversion module, a main control module and a protection module which are connected in sequence. The charging pile system comprises a second power supply module, a battery pack and a discharging module which are connected in sequence. The fault monitoring module is connected with the output end of the second power supply module, the protection module is arranged on a circuit between the battery pack and the discharging module, and the protection module is connected with the output end of the main control module. Oervoltage, undervoltage and overcurrent faults of the power supply circuit of the charging pile system can be monitored in real time, and when the faults occur, the discharging circuit of the discharging module of the charging pile system can be disconnected in time to prevent safety problems.

Description

technical field [0001] The invention relates to the technical field of charging pile monitoring, in particular to a monitoring system for a one-machine four-pile charging pile system. Background technique [0002] With the increasing shortage of energy, new types of vehicles marked by energy saving and environmental protection are about to emerge. Countries around the world are enthusiastic about new energy vehicles such as electric vehicles. Models and their supporting facilities. [0003] In order to promote the popularization of electric vehicles in the world, in addition to technological breakthroughs and unified standards, related infrastructure construction must also be carried out simultaneously. In recent years, with the country's vigorous development of new energy vehicles, new energy vehicles have developed by leaps and bounds, but the corresponding charging facilities have become the biggest shortcoming that restricts the rapid advancement of new energy vehicles,...
