General-type charging connector converter of electric bicycle

Abstract

The invention discloses a general-type charging connector converter of an electric bicycle. The general-type charging interface converter comprises a small-power bridge rectifier module, a power supply module, a photoelectric coupler module, a relay module, an LED (Light Emitting Diode) lamp module and a large-power bridge rectifier module. After the converter is connected into a charging connector of the electric bicycle, the photoelectric coupler module acquires information of an interface mode of the electric bicycle from an electric bicycle connector, and then the relay module is controlled, so that a relay skips to a corresponding connector mode; current output by a charger passes through the relay module and then is communicated to the electric bicycle; finally, a process from conversion to charging is finished. The general-purpose charging connector converter of the electric bicycle has the beneficial technical effects that chargers with different charging connectors can be used for charging electric bicycles with different charging connectors, and the technical problems that the connector mode is not compatible so that the electric bicycles cannot be charged or the charger is damaged and the like are solved.

Description

technical field [0001] The invention belongs to the field of power converters, and in particular relates to a universal charging interface converter for electric bicycles. Background technique [0002] With the rapid development of society and people's increasing emphasis on environmental protection, many cities have introduced policies to prohibit motorcycles from being used on the road, and the electric bicycle industry has thus developed rapidly. Electric bicycles have been recognized by people for their superior convenience and comfort, and have become the best product to replace motorcycles. [0003] As electric bicycles are used by more and more people, the brands of electric bicycles have also increased from the initial few to dozens. While the increasing number of electric bicycle brands bring convenience to consumers' purchase choices, they also throw an important problem to users: the charging interfaces or chargers between different brands of electric bicycles ar...
