Flow card is an essential part of charging pile, because the existence of flow card can ensure that charging pile can play a very important role and meet the needs of consumers. The flow card empowers the charging pile and can accurately locate it. When the owner needs to charge the electric vehicle, it can quickly help the owner find the location and ensure the endurance of the owner. The distribution area of charging piles is uncertain and scattered, so it is difficult for unfamiliar car owners to find charging piles. The charging pile itself is a precise electronic instrument with complex internal structure, which is prone to failure. Only managers can find faults by on-site investigation, and the management fee is time-consuming and laborious. Intelligent charging piles are connected to the Internet of Things flow card, and relevant information is collected by sensors and uploaded to the Internet of Things, so as to realize the functions of charging pile positioning, charging and discharging control, charging pile state monitoring, charging pile surrounding environment monitoring, and unified management of multiple charging piles.
