Abstract

The invention discloses a relay detection and control device for an AC charging pile. The relay detection and control device comprises a relay detection module, a detection control switch, an optocoupler isolation output module and a main control chip, wherein the relay detection module is respectively connected with the optocoupler isolation output module and at least one detected relay, the maincontrol chip is respectively connected with the optocoupler isolation output module and the detection control switch, the detection control switch is used for controlling the relay detection module to be powered on or powered off, and the relay detection module is used for controlling the optocoupler isolation output module to output a detection signal; and the main control chip acquires the on-off state signal of the detected relay in real time, judges whether the on-off state signal and the detection signal accord with a preset relay state matching relationship or not when entering a contact adhesion detection mode, and sends a cut-off instruction to the air switch if the on-off state signal and the detection signal do not meet the preset relay state matching relationship. The relay action can be detected and disconnection of the relay can be effectively controlled so that safety and reliability of the charging pile can be enhanced and user safety and vehicle charging safety can beguaranteed.

Description

technical field [0001] The invention relates to the technical field of electric vehicle charging, in particular to an AC charging pile relay detection and control device and an AC charging pile. Background technique [0002] With people's emphasis on green travel, electric vehicles are becoming more and more popular, and there are more and more charging equipment such as charging piles. The charging safety and reliability of these charging equipment are also attracting attention. The inventor conducted investigation and research on the existing charging piles and found that the AC power supply relay of the AC charging piles had a phenomenon of contact adhesion and could not be quickly tripped under high current working conditions, which resulted in the failure of the charging piles to control the normal power failure and Maintenance is required, and more seriously, there is a risk of electric shock to the operator and overall loss of control when other failures occur at the ...
