Abstract:
The application relates to a system for charging a battery of an electrical vehicle. The electrical vehicle charging system of the present application is helpful for decreasing the converter capacity while maintaining the charging capacity and electrical vehicles with various nominal voltages can be charged simultaneously. In one aspect the system for charging an electrical vehicle includes: a plurality of central converters, at least one switch electrically connected to the central converters, at least one transformer electrically connected to an external AC power supply, at least one distributed converter for supplying at least one distributed DC voltage with a level below that of the central converter, and a controller connected to the at least one switch.
