PacificAutomotive.com Generally this situation is caused by abnormal communication of the charging equipment, such as the local network is not good and other reasons. It is necessary for the charging station operator to send technicians to deal with the scene, and it is more difficult for the user side to solve the problem. Once found this situation is best to inform the charging station operation and maintenance personnel in a timely manner, if there is someone on duty is better. If no one is on duty, there is usually a customer service phone number to call, which is free of charge.
Charging pile background communication module offline problem rectification program VIP agency copyright 2 points 211 read 3 download 2019-06-21 uploaded 2 pages charging pile background communication module offline problem rectification program from 2020 the country built 4.5 million charging piles plan to move forward for another year, but the number of public **** charging piles is still less than 250,000 and the utilization rate is not high, and its pile communication The problem of pile communication is particularly prominent.
In 2016, many companies transformed charging pile of the big wave of the past, what are the gains and losses worth learning first look at a more prominent problem: background communication drop. In fact, whether it is paid settlement or basic operation and maintenance, keep the pile and background communication is a basic requirement, but in the national network charging pile does not meet this basic requirement of the pile accounted for as high as 10%: Figure 1 charging pile drop problem rectification recommendations according to the national network released three months of operation data, charging piles offline time is not lack of more than 1,000 hours, converted into the number of days of operation month for one month.
Figure 2: Statistical table of offline time of charging piles in Shanghai Part of how to determine the background communication abnormality According to the State Grid's investigation, the main cause of the offline problem is that the dialing logic of the TCU's hardware manufacturer is defective, and it needs to be standardized in order to avoid it, which coincides with the situation of the back-end offline problem encountered by Zhengyuan at the early stage of the development of the TCU, and it proposes the process of preventing and controlling the offline problem that is similar to the idea of the next State Grid: Figure 3: Overall flow chart of the dialing logic issued by the State Grid. The overall flow chart of the dialing logic promulgated by the State Network, in which the SIM card is judged to be in position for the two-layer test, and only when two acquisitions fail is it judged to be out of position, and if it is in position, the SIM card with better communication quality is selected for dialing, and then the link stability quality is judged by the questions of "whether the PPP device is in position, whether the IP address is correct, and whether the traffic is generated during the cycle" and "whether the link quality is stable". Then further by "whether the PPP device is in position, whether the IP address is correct, whether traffic is generated during the cycle" to determine the link stability quality, if unstable then need to restart the device.
