Electric vehicle charging system with transformer, converter, and charging apparatus
A recently granted patent (Publication Number: US11772506B2) describes an electric vehicle (EV)-charging system that aims to efficiently distribute power to charging apparatuses installed on utility poles. The system includes a transformer connected to a distribution line, a converter that converts power from the transformer into charging power, and a charging apparatus installed on a first utility pole to receive and supply the charging power to the EV.
The system features a first port that provides charging power directly to the EV and a second port that provides the charging power converted by the converter. A blocking unit is included to switch the path between the first and second ports. A control unit is responsible for receiving load amount information of the transformer linked to the distribution line. If the load amount information exceeds a standard load amount, the control unit opens the path between the first and second ports.
The converter in the system consists of a first converter that converts power from the transformer into slow charging power and a second converter that converts power into quick charging power. The first converter supplies the slow charging power to the EV-charging system, while the second converter supplies the quick charging power. The converter is installed on a second utility pole, while the first utility pole is connected to the distribution line.
In addition, the patent mentions that the converter is installed at a higher position than the charging apparatus on the utility pole or the second utility pole. Furthermore, the transformer is installed on the second utility pole.
The system also includes an underground cable for electrically connecting the converter and the charging apparatus. This underground connection ensures a reliable and efficient transfer of power between the two components.
Overall, this patented EV-charging system offers a solution for effectively distributing power to charging apparatuses installed on utility poles. By utilizing multiple converters and a control unit, the system can optimize power distribution based on the load amount of the transformer. The inclusion of an underground cable further enhances the reliability and efficiency of the system.
