Charging method for charging pile system achieving precise payment

Abstract

The invention relates to a charging method for a charging pile system achieving precise payment. The charging pile system comprises a public network cloud, a communication controller, charging piles, relays and electric quantity measuring chips, 10-32 minimum charging units are connected to a principal line of the communication controller in series, all the minimum charging units are connected together in series through RS-485 principal lines, all the RS-485 principal lines are merged into a principal line of the communication controller at a garage entrance, and the communication controller is internally provided with GPRS modules; each minimum charging unit comprises one charging pile with eight output lines and the relay and the electric quantity measuring chip which are connected with the charging pile in series. Accordingly, a WeChat account is bound with ID of one charging pile through a WeChat official account, a user can conduct mobile terminal recharging on a recharge card, the trouble that the user queues up in a sales network to conduct recharging is omitted, and the purpose that recharging is conducted anywhere or anytime without being limited by the environment and the time is achieved.

Description

technical field [0001] The invention relates to the field of charging piles, and more specifically, to a method for charging and using a charging pile system with accurate payment. Background technique [0002] Some communities adopt the method of fixed parking spaces. Cars can only park in designated parking spaces, and only one car can be parked in one parking space, so as to prevent one card from being swiped multiple times to park multiple cars. It is difficult to charge reasonable parking fees for the parking spaces of electric vehicles. Some people do not need to charge for parking, and some people often charge for parking. [0003] At present, the charging piles of many companies in the market use 5-10 charging piles to share a GPRS module, and use a GPRS module to communicate between the 5-10 charging piles under its jurisdiction and the background cloud server. If an underground garage needs to install 200 charging piles, then 20-40 GPRS modules are needed, which w...

Problems solved by technology

[0004] However, when the number of charging piles increases, the probability of failure of the GPRS module of the charging pile will also increase. Once a failure occurs, the charging pile will not be able to communicate with the background control system, so that the transmission of charging piles will not be possible. internal data

If the maintenance personnel directly open the charging pile for repair, it is very easy to cause the data inside the charging pile to be lost, which will cause troubles to the subsequent maintenance and unified management of the charging pile. Therefore, there is an urgent need for a maintenance personnel. Back up the data inside the charging pile, so as to smoothly diagnose and repair the charging pile equipment, to prevent data loss caused by repairing the charging pile

[0005] At the same time, since the same electric vehicle charging pile often has multiple charging interfaces, when the power limit is imposed on the charging pile, only the power of each charging interface on the charging pile will be controlled. It is often impossible to charge, or when multiple charging piles supply power at the same time, it is easy to exceed the total power that the input line can carry, so these charging piles can no longer meet the needs of users
