OEM odm electric vehicle plug in stations manufacturer factory

The electric vehicle charging station is a station for charging electric vehicles. With the popularization of electric vehicles, electric vehicle charging stations will become the focus of the development of the automobile industry and energy industry. The electric vehicle charging station can better solve the problem of fast charging, energy-saving, and emission reduction.

Conventional charging

1. Size of typical conventional charging station

According to the data of conventional charging of electric vehicles, a charging station is generally configured with 20~40 electric vehicles. This configuration is to take full advantage of the valley power at night for charging. The disadvantage is that the utilization rate of charging equipment is low. If charging is also considered during peak hours, 60~80 electric vehicles can be used to configure a charging station. The disadvantage is that the charging cost increases and the peak load increases.

1. Typical configuration of charging station power (provided that the charging cabinet has harmonic and other processing functions)

Scheme A: build the distribution station, design two 10kV cable inlets (equipped with 3*70mm cables), two 500KVA transformers, and 24 380V outlets. Two of them are dedicated outgoing lines for fast charging (with 4*120mm cable, 50m length and 4 circuits), two are mechanical charging or standby outgoing lines, and the rest are conventional charging outgoing lines (with 4*70mm cable, 50m length and 20 circuits)

Scheme B: two 10kV cables (equipped with 3*70mm cables) are designed, two 500KVA user box transformers are set, each box transformer is equipped with four 380V outgoing lines (equipped with 4*240mm cables, 20m long and 8 circuits), and each outgoing line is equipped with a 4-circuit cable branch box to supply power to the charging cabinet (equipped with 4*70mm cables, 50m long and 24 circuits).

Fast charging

1. Size of typical fast charging station

According to the data of rapid charging of electric vehicles, a charging station is generally configured to charge 8 electric vehicles at the same time.

1. Typical configuration of charging station power

Scheme A: build the distribution station, and design two 10kV cable inlets (equipped with 3*70mm cable), two 500KVA transformers, and ten 380V outlets (equipped with 4*120mm cable, 50m length, and 10 circuits).

Scheme B: two 10kV cables (equipped with 3*70mm cables) are designed, and two 500KVA user box transformers are set. Each box transformer is equipped with four 380V outgoing lines for charging power station (equipped with 4*120mm cables, 50m long, 8 circuits).

Mechanical charging

1. Size of mechanical charging station

Small mechanical charging stations can be considered in combination with the construction of conventional charging stations, and transformers with larger capacity can be selected as required. A large mechanical charging station is generally configured with 80~100 sets of charging batteries at the same time. It is mainly applicable to the taxi industry or battery rental industry. It can charge 400 sets of batteries without interruption.

1. Typical configuration of charging station power supply (large mechanical charging station)

Two 10kV cable inlets (equipped with 3*240mm cable), two 1600KVA transformers and ten 380V outlets (equipped with 4*240mm cable, 50m length and 10 circuits) in the distribution station.

Portable charging

1. Villa: with three-phase four wire meter and independent parking garage, the existing residential power supply facilities can be used to put a 10mm2 or 16mm2 line from the residential distribution box to the special socket in the garage to provide portable charging power.

1. General residence: it has a fixed centralized parking garage. Generally, it requires an underground parking garage (for charging safety). It can be transformed by using the original power supply supporting facilities of the community. It must be considered according to the existing load capacity of the community, including the load of valley power. The specific scheme shall be determined according to the power supply facilities, scheme and building environment of the community.
