Design of High-Power and Low-Power Three-Phase AC Charging pile Based on Magnetic Latching Relay

Jiang Yan-huan，Pan Jia

[Abstract]A three-phase AC charging pile with high power and low power consumption was designed based on bipolar magnetic holding relay. This charging pile has the characteristics of low power consumption， small volume and low cost. It also supports functions such as card swiping operation， touching screen operation， power detection， emergency stop switch and CP signal control and detection.The main structure of charging pile and the hardware circuit structure are designed.It mainly includes magnetic holding relay control circuit， power consumption detection and CP signal control and detection circuit.The prototype test shows that the designed three-phase AC charging pile can charge electric vehicles under the state of low power consumption for a long time， making the system safer and more reliable for charging electric cars. It has the characteristics of low power consumption， small volume and low cost， and can be applied to the field of new energy electric vehicle charging.
