Control method of electric car-mounted charging device

Abstract

The invention provides a control method of an electric car-mounted charging device, and the control method comprises following steps of step A, inputting a preset charging parameter into a controller module; step B, detecting whether a power factor correction circuit and a resonance oscillation circuit have abnormality or not by utilizing the controller module, displaying error information if abnormality exists, and executing a step C when no abnormality exists; step C, controlling and starting a charging device to enter a charging status by utilizing the controller module so as to charge a storage battery, utilizing a controller to monitoring the entire charging process, immediately stopping the charging or adjusting the charging status when abnormality is discovered, and executing a step D when no abnormality is discovered; and step D, when detecting that the storage battery is fully charged through the controller module, and controlling the charging device to stop charging. Due to the adoption of the control method, the difficulties that the traditional charging device is insufficient for protecting an electric network and the controller area network (CAN) communication has safety potential danger can be solved, and simultaneously the charging efficiency can be improved.

Description

technical field [0001] The invention relates to a method for controlling a charging device, in particular to a method for controlling a vehicle-mounted charging device for an electric vehicle. Background technique [0002] Due to its environmental protection, energy saving, low noise and other advantages, electric vehicles have gradually become an effective and safe means of transportation. The construction of charging stations plays an important role in the development of electric vehicles. An excellent charging mode for electric vehicles will play a greater role in the popularization of electric vehicles. big boost. [0003] At present, the electric vehicle charging device and its control system have not yet been popularized, and the national standard on the charging interface has not yet been released. The charging devices introduced by some manufacturers, mainly charging connectors, have inconsistent structures and are expensive. The system itself is not very efficient....
