Shandong charging pile manufacturer evcome New Energy Co., Ltd. focuses on charging pile research and development/design/production/sales/one-stop service, providing customers with professional and comprehensive Shandong charging pile charging equipment and charging operation station construction integrated solutions, for you Introduce the product classification of Shandong charging pile in detail, including the usage, model, range, pictures, news and price information of all charging pile products. Charging piles are charging equipment for electric vehicles, which are divided into AC charging piles and DC charging piles. DC charging piles are fixedly installed outside the electric vehicle and connected to the AC grid to provide high-power DC power supply for the electric vehicle power battery. The DC charging pile adopts a three-phase four-wire power supply system, which can provide sufficient power, and the output voltage and current adjustment range is large (suitable for the voltage requirements of passenger cars and buses), and fast charging can be realized. DC electric vehicle charging station, commonly known as“fast charge”, it is a power supply device that is fixedly installed outside the electric vehicle and connected to the AC power grid to provide DC power for the power battery of the off-vehicle electric vehicle. The working principle of the DC charging pile: the three-phase 380V AC power enters the three-phase four-wire ammeter after passing through the EMC and other lightning protection filter modules, and the three-phase four-wire ammeter monitors the actual charging power of the entire charger when it is working. And according to the actual charging current and charging voltage, the chargers often need to be used in parallel, so the charger is required to have the function of current sharing output, and the output of the charger can directly charge the power battery through the charging gun. When the DC charging pile is working, the auxiliary power supply supplies power to control systems such as the main control unit, display module, protection control unit, signal acquisition unit, and card swiping module. In addition, during the charging process of the power battery, the auxiliary power supply supplies power to the BMS system, and the BMS system monitors the status of the power battery in real time.
