The promotion and development of electric vehicles in China has been unsatisfactory. Among them, the charging problem of electric vehicles has always been the main factor restricting the development of new energy vehicles. The problems faced by charging pile manufacturers and the entire charging pile industry:. 1. Low utilization rate: The utilization rate of public charging piles is less than 10%. The current utilization rate of State Grid Corporation is only 5. The charging pile manufacturers rank 3%, and the utilization rate of expressway charging piles is even less than 1%. 2. The failure rate of charging equipment (modules) is high: the current installed charging equipment (module new energy charging pile manufacturers) is no longer than three years (far lower than the 10-15 years required by the bidding), high temperature, high humidity, high The module failure rate in the salt environment is higher. In addition, the charging pile manufacturer does not maintain it in time, and the overall equipment life is short. 3. The charging experience is poor, and it is generally reflected that charging is difficult: the installation rate of private charging piles is low, and it is difficult to realize sharing. Automobile charging pile manufacturers have lower utilization rates in highways, remote areas, and higher operation and maintenance costs. DC fast charging piles in urban public charging stations It is relatively small (28% of the total), and the service efficiency of car charging piles is low. First of all, we need to clearly know which work needs to be prepared before using the car charging pile, as shown below. One: Daily inspection, check whether there are flammable items around the charging pile of pure electric vehicles. Two: Check whether the charging pile is normal, and then check the display screen (the display screen will show when the device fails). Charging pile solution. Three: Check whether the charging cable is suitable for the model. If you are using a car with the old national standard, don’t worry about it, because the new national standard is compatible with the old national standard, and it can be used for OEM charging piles without accidents. If you are using a car with the new national standard , Of course, most of them are new national standards now. At this time, you need to look at the gun head. The gun head will have an electronic lock. In addition to checking whether the charging pile is customized to check whether the gun head matches, you should also pay attention to it. Do not use the charging gun with a dirty core. Charging piles, using such charging piles is easy to cause charging short circuit, so the charging pile ODM will greatly damage the charging port of the car. Four: Be sure to read the charging process of the charging pile carefully before charging. The charging process of each manufacturer’s charging pile is different. Read the charging process carefully to prevent charging failure. Before charging, make sure that the gun is actually plugged into the socket and the gun head It matches the socket, as long as you plug it in hard, it can generally be plugged in, and the charging pile is OEM.
