Conventional charging
(1) Scale of typical conventional charging stations
According to the data of conventional charging of electric vehicles, generally 20~40 electric vehicles are equipped with a charging station. This configuration takes full advantage of late valley electricity for charging, but the disadvantage is low utilization rate of charging equipment. If charging is also considered during peak hours, 60~80 electric vehicles can be used to prepare a charging station. The disadvantage is that charging cost increases and peak load increases.
(2) Typical power matching configuration of charging station (the premise is that charging cabinet has harmonic processing function)
Plan a:
The construction distribution station designs two 10KV cable intakes (with 3*70mm cables), two 500KVA transformers, and 24 380V outgoing lines. The second route is dedicated outlet for quick charging (with 4*120mm cable, 50M long and 4 loops), the second route is mechanical charging or standby outlet, and the rest are conventional charging (with 4*70mm cable, 50M long and 20 loops).
Plan b:
Design two 10KV cable lines (with 3*70mm cable), set two 500KVA user box transformer, each box transformer with four 380V outlet (with 4*240mm cable, 20M long, 8 loop), each outlet set a 4-loop cable branch box to supply power to the charging cabinet (with 4*70mm cable, 50M long, 24 loop).
