Alternating current charging pile

Abstract

The invention relates to the field of electric automobile charging, in particular to an alternating current charging pile which comprises a main MCU (micro-control unit) unit. The main MCU unit is respectively connected with a card reading unit, a charging loop unit, an input unit, a display unit, a metering unit, an electromagnetic warehouse unit, a voice guide unit, a standby power supply unit, a lightning protection leakage unit, a communication unit and a dip angle detection unit through a total data line, and the display unit comprises an operation display module and an equipment state display module. The alternating current charging pile has the advantages that charging completeness is maintained, charging complaint caused by power failure is reduced, the standby power supply unit can be circularly charged when power is supplied again, and the service lives of the standby power supply unit and a vehicular battery are prolonged.

Description

technical field [0001] The invention relates to the field of electric vehicle charging, in particular to an AC charging pile. Background technique [0002] Cars were once hailed as machines that changed the world. While bringing us fast transportation, they also created a series of problems such as energy security, environmental pollution and global warming. At present, energy conservation and emission reduction have become the top priority of the global auto industry, and the development of new energy vehicles has become the strategic direction of the global auto industry. New energy vehicles are expected to become machines that will change the world again. [0003] As an outstanding representative of new energy development, electric vehicles have become an important development direction to replace traditional power vehicles and lead the new era of the automotive industry. At present, the world's automobile industry is actively participating in the development and promoti...
