Abstract

The invention provides a host fault processing method and system and a charging pile. The method comprises the following steps: when a host detects that the receiving of the host is abnormal, closing the sending function of the host; and after other machines detect that the host is disconnected, one slave machine is selected from the other machines to serve as the host through master searching, and the other machines are charging modules which are connected to the same CAN bus with the host. By closing the sending function of the host which receives abnormally, the host which receives abnormally quits the host election, all other hosts carry out host searching operation, and the unique host is determined, so that the fault processing mode is simple, and the system runs stably.

Description

technical field [0001] The invention relates to the technical field of electric vehicle charging control, in particular to a host fault handling method, system and charging pile. Background technique [0002] Generally, multiple charging modules are installed in the electric vehicle charging pile, so as to charge multiple electric vehicles that come to charge, reduce the queuing time of electric vehicles, and improve charging efficiency. At present, multiple charging modules generally use the master-slave current sharing method for charging, that is, the master is accurately found, the master issues a current sharing command, and the slave outputs current according to the current sharing command. [0003] At present, when host duplication occurs, that is, there are multiple hosts, if one of the hosts has an abnormal reception failure, usually the charging module that receives the abnormality exits the host, and the other host performs host duplication detection, exits the ho...
