Abstract
A smart, integrated charging device for electric vehicles is provided. The alternating current input module is connected to an electricity metering module via an alternating current input switch. The charging module is connected to the electricity metering module via a module alternating current switch and an alternating current bus, and is connected to an output monitoring module via a direct current bus. The output monitoring module is connected to the monitoring and general control module (13). The direct current output module is connected to the output monitoring module (4) via a direct current output switch. The lightning protection module is connected to the direct current bus. The charging module utilizes smart power combination and multiple output coordination to enable output with current sharing and the automatic balance control technology.
