The main function of AC charging pile (AC charging pile) is to provide slow charging service for electric vehicles. Its working principle is to charge the battery pack of electric vehicles through AC power. The specific process is as follows:
Charging principle: AC charging pile provides AC power, and the on-board charger (OBC) built into the electric vehicle converts AC power into DC power, and then supplies it to the battery for charging.
Charging speed: Since the power of AC power is low, usually between 7KW and 22KW, the charging speed is slow, and it usually takes 4-8 hours to fully charge an electric vehicle. The specific time depends on the battery capacity of the vehicle and the power of the charging pile.
Applicable scenarios: AC charging piles are suitable for small-scale charging scenarios such as home, community, and office areas. Due to its simple installation and low cost, it is particularly suitable for users with fixed parking spaces, and is suitable for use at night or for long-term parking.
Advantages: AC charging piles have low cost, simple structure, do not require complex power conversion equipment, have good compatibility, and are suitable for various electric vehicles. In addition, it has low requirements for the power grid and is easy to install, which is particularly suitable for old communities and remote areas.
From the above functional description, it can be seen that AC charging piles play an important role in electric vehicle charging, especially in home and daily use.
