Description

A method for charging and using a charging pile system with a bluetooth interface

technical field

The invention relates to the field of charging piles, and more specifically, to a method for charging and using a charging pile system with a Bluetooth interface.

Background technique

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.

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 will inevitably increase the hardware cost. At the same time, the GPRS module communication needs to pay a service fee every month. In the long run, this ratio cannot be ignored. cost.

However, as 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 the charging pile 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 trouble for subsequent maintenance and unified management of the charging pile. Back up the data inside the charging pile, so as to smoothly diagnose and repair the charging pile equipment, and prevent data loss caused by repairing the charging pile.

At the same time, since the same electric vehicle charging pile often has multiple charging interfaces, when the power of the charging pile is limited, 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.

On the other hand, as 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 communication between the charging pile and the background control system will be impossible, so that the transmission will not be possible. Internal data of the charging pile. 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 trouble for subsequent maintenance and unified management of the charging pile. Back up the data inside the charging pile, so as to smoothly diagnose and repair the charging pile equipment, and prevent data loss caused by repairing the charging pile.
