AC nabíjanie hromady môžem tiež be volaním pomalým nabíjaním, ktorý vyžaduje an na palube nabíjačka na transformáciu a opravu na výstup DC napájanie. The AC nabíjanie hromada iba poskytuje napájanie výstup a má nie nabíjanie funkciu. It potrebuje na byť pripojené k nabíjať nabiť elektrický vozidlo. It je ekvivalentný k len prehrávanie a rolu v ovládanie napájanie napájanie.
Because the on-board charger is relatively small, the power is low, and the charging process is slow. Taking the commonly used 7KW household charging pile as an example, according to the formula of charging capacity (W)=power (P) × charging time (t), we can calculate that it takes about 8 hours to fully charge a 56KW new energy vehicle. Therefore, it is used in scenarios that do not require fast charging, such as private charging piles and underground garages. The structure of the AC charging pile is relatively simple and the cost is low. It is mainly composed of control board, power input and output circuit, charging connector, human-computer interaction unit and other components. The main board accounts for nearly 30 percent of the cost, followed by the gun cable and the housing, which also account for about 30 percent of the cost. The main board plays the role of metering and protection, the shell provides support and human-computer interaction, and the charging gun is responsible for charging.
