Top ten brands of charging piles, which brand of charging piles is better? Which brand of charging pile is good? How to choose a charging pile brand? According to the statistical analysis of the top ten brands of charging piles, Shenzhen evcome New Energy Co., Ltd. specializes in R&D and production of charging piles. It is a national high-tech enterprise. Charging piles can be fixed on the ground or walls and installed in public buildings ( Public buildings, shopping malls, public parking lots, etc.) and residential area parking lots or charging stations, charging various types of electric vehicles according to different voltage levels. There are two charging methods: constant current charging and constant voltage charging. 1. The constant current charging method is a charging method that keeps the charging current intensity constant by adjusting the output voltage of the charging device or changing the resistance in series with the battery. The control method is simple, but because the acceptable current capacity of the battery gradually decreases with the progress of the charging process. In the later stage of charging, the charging current is mostly used for electrolyzing water, generating gas, and causing excessive gas output. Therefore, the stage charging method is often used. 2. The voltage of the charging power source maintains a constant value during the entire charging time, and the current gradually decreases with the gradual increase of the battery terminal voltage. Compared with the constant current charging method, its charging process is closer to the optimal charging curve. Fast charging with constant voltage, because the electromotive force of the battery is low at the initial stage of charging, the charging current is very large, as the charging progresses, the current will gradually decrease, so only a simple control system is needed. How to choose a charging pile? 1. Know in advance the power, voltage, charging time, whether there is a password lock, charging fees, and settlement methods of the charging equipment; 2. What procedures and materials need to be prepared, and which organizations need to be coordinated; 3. Whether the charging pile is free and installed Is it free, what are the conditions for free installation, and will there be any other additional costs; 4. Whether the parking area meets the installation conditions, and whether the service provider can survey in advance; 5. Who is responsible for the quality assurance of the charging piles? Find someone to solve.
