虽然三级快速充电主要是直流，但也有交流版本。与充电桩的共同之处在于较少的电源管理（转换）和更多的能量监测、诊断和通信，这些功能对于商业应用是不可或缺的。这使得提供为客户充电站的商业场所（如办公楼或餐馆）的所有者能够为车辆快速充电，以更好地优化电费并对充电车主收取适当的费用。

While level 3 quick charge mainly dc, but also a communication version. Common with the charging pile in less power management (conversion), and more energy monitoring, diagnosis, and communication, these functions are indispensable for commercial applications. Which provide for the customer charging station business places, such as office building or restaurant owners can recharge vehicle quickly, in order to better optimize the electricity to charge the owner the appropriate fee.

最后，要注意这些系统被认为是工业解决方案。建造充电站和充电桩所需的组件不必须是汽车级版本。汽车级解决方案需要更严格的资质，因此建造更耗时和昂贵。

Finally, attention should be paid to these systems is considered to be industrial solutions. Components needed to build the charging station and charging pile version don't have to be auto level. Auto level solutions need to be more strict qualification, so build more time-consuming and expensive.
