EVCOME EV charging stations for better life---Top EV charging stations manufacturers & suppliers in China.
There are a few things to keep in mind when purchasing an electric vehicle charging pile. 1. Production process - including the raw materials or parts used in the production process and the basis of assembly inspection technology, etc., a good production process of the charging pile manufacturer can promote the stable performance of the charging pile during use. 2. Charging speed - it can shorten the time for customers to wait for charging and improve the user's charging experience without delaying the use of charging pile manufacturers. Therefore, it is necessary to choose products from car charging pile manufacturers with intelligent technology and high performance and fast speed. 3. Warranty period-Regular manufacturers will have a certain warranty period for charging pile products, so users should pay attention to the length of warranty period provided by the manufacturer for charging piles when choosing, which can directly affect the user's installation. The security after use and the implementation of professional maintenance measures. 4. Whether the types are complete - for example, according to different installation methods, it can be divided into wall-mounted or floor-mounted charging piles. According to different installation locations and usage occasions, there are public car charging pile manufacturers and special types. One pile one charge or one pile multiple charge form. Those who are using electric vehicle charging piles know that electric vehicle charging piles will leak electricity. Electric vehicle charging pile leakage current is generally divided into four types, namely: semiconductor component leakage current, power supply leakage current, capacitor leakage current and filter leakage current. 1 Pure electric vehicle charging pile, semiconductor original leakage current, very small current flowing through the PN junction when it is cut off, D-S is forward biased, G-S is reverse biased, after the conductive channel is opened, D to S will have The current charging pile solution flows, but in fact due to the existence of free electrons, the attachment of free electrons to SIO2 and N+ causes D-S to have a leakage current. 2. The leakage current of the power supply. The switching power supply is manufactured for the charging pile to reduce interference. According to the national standard, an EMI filter circuit must be installed. Due to the relationship between the EMI circuit, there is a slight drop to the ground after the switching power supply is connected to the mains. Current, this is the leakage current. If it is not grounded, the computer case will have a voltage of 110 volts to the ground, and it will feel numb when touched by hand, and it will also affect the work of the computer. 3 Charging pile ODM, capacitor leakage current, capacitor medium is impossible.. non-conductive, when the capacitor is applied with DC voltage, the capacitor will have a leakage current, if the leakage current is too large, the capacitor will be heated and damaged, except for electrolytic capacitors, The leakage current of other capacitors is extremely small, so the insulation resistance parameter is used to represent its insulation performance, while the electrolytic capacitor has a large leakage current, so the leakage current is used to represent its insulation performance (proportional to the capacity), charging pile OEM.
