Conventional charging:

① 典型常规充电站的规模

The scale of typical conventional charging stations

根据目前电动汽车常规充电的数据资料，一般以20~40辆电动汽车来配置一个充电站，这种配置是考虑充分利用晚间谷电进行充电，缺点是充电设备利用率低。在高峰时也考虑充电，则可以60~80辆电动来配制一个充电站，缺点是充电成本上升，增加高峰负荷。

According to the current data of conventional charging of electric vehicles, a charging station is usually configured by 20~40 electric vehicles. This configuration is to consider fully utilizing the night valley electricity to charge, and the disadvantage is that the utilization rate of charging equipment is low. When the charging is considered at the peak, a charging station can be made by 60~80 electric vehicles. The disadvantage is that the charging cost is rising and the peak load is increased.
