The invention provides a remotely-controlled electric car alternating current charging pile and an application method. The charging pile comprises alternating current charging pile bodies, mobile phone clients and an Internet-of-Vehicles platform. The owner of each alternating current charging pile body installs the alternating current charging pile body by the road, an electric car owner and the owner of each alternating current charging pile body each has a mobile phone client, the Internet-of-Vehicles platform is installed in a power grid operating company, signals emitted by the mobile phone clients act on the signal receiving end of the Internet-of-Vehicles platform, the signals output by the signal output end of the Internet-of-Vehicles platform act on the signal input ends of the mobile phone clients and the signal input end of each alternating current charging pile body, the signal output by the signal output end of each alternating current charging pile body acts on the signal receiving end of the Internet-of-Vehicles platform, and the Internet-of-Vehicles platform can monitor the working states of multiple alternating current charging pile bodies in real time through a display screen. The owner of the alternating current charging pile can achieve profitability, convenience is brought to the car owner, and the alternating current charging pile has positive significance for promoting development of the electric industry.
