DC charging pile quickly charge the batteries of electric vehicles by converting AC power directly into DC power. During the charging process, the charging station communicates with the vehicle to negotiate charging power and current to ensure efficient and safe charging. The internal structure of the DC charging pile includes a rectifier, converter and controller, which allows the DC charging pile to deliver high power output current, usually up to 120KW or more, making the EV fully charged in a very short period of time. DC充電堆的這種充電方法特別適合公共充電站和長途旅行充電需求。它還支持各種充電協議,例如Chademo和CCS,以高兼容性。
