Characteristics of charging station cable products
The function of a charging station is similar to that of a gas dispenser in a gas station. It can be fixed on the ground or walls, installed in public buildings (such as public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. It can charge various models of electric vehicles according to different voltage levels. The input end of the charging station is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles. There are two types of cable charging methods for charging stations: AC and DC.
AC charging station cable
1. Environmental condition requirements
① Rated working voltage: 450/750V
① Working environment temperature: -40 ℃~+50 ℃;
② Relative humidity: 5% to 95%;
③ Altitude: ≤ 1000m;
2. Structural requirements
① The cable sheath of the AC charging station should be sturdy and wear-resistant;
② Structurally, it is necessary to prevent exposure in areas that are easily touched by hands;
④ The sheath shall be made of materials with strong impact resistance, good anti-theft performance and aging resistance;
⑤ The non insulating material casing should be reliably grounded;
3. Power requirements
① Input voltage: single-phase 220V;
② Output power: single-phase 220V/5KW;
③ Frequency: 50Hz ± 2Hz;
④ The allowable voltage fluctuation range is: single-phase 220V ± 15%;
4. Electrical requirements
① After confirming the correct connection between the plug and socket, the circuit with load can be opened and closed to achieve power supply to the socket;
② The leakage protection device should be installed on the incoming side of the power supply cable and connected to the auxiliary line;
③ The protection of low-voltage distribution equipment and lines should comply with the relevant provisions in the Design Code for Low Voltage Distribution (GB/50053);
④ When charging the charging station cable, when the first grounding fault occurs, the insulation monitoring device should emit an audio or light signal through the control line. When the second out of phase grounding fault occurs, the fault circuit should be cut off by the overcurrent protection device or leakage current action protector;
DC charging station cable
1. Environmental condition requirements
① Rated working voltage: 1.0 KV
① Working environment temperature: -40 ℃~+50 ℃;
2. Structural requirements
① The cable housing of the AC charging station should be sturdy;
② Structurally, it is necessary to prevent hands from easily touching exposed parts;
③ The charging station cable should have good shielding function against electromagnetic interference;
④ The sheath shall be made of materials with strong impact resistance and aging resistance;
4. 3. Power requirements
① Input voltage: three-phase four wire 380VAC ± 15%
② Frequency: 50Hz ± 5%;
2) The charging station cable should meet the charging needs of electric vehicles;
3) The cable output of the charging station is DC, and the output voltage meets the battery standard requirements of the charging object;
4) The maximum output current of the cable meets the charging requirements of the charging object's battery standard 1C and is compatible downwards;
5) There are two types of charging methods: conventional and fast. The conventional method is 5-hour charging, while the fast method is 1-hour charging (charging station cables should meet the charging environment for different charging methods);
The main uses of charging station cables
1) The charging station cable provides range capability for electric vehicles.
2) Provided feasibility for the popularization of electric vehicles.
3) The signal line in the charging station cable should have corresponding alarm and protection functions for abnormal states during the charging process;
4) The charging station cable control line monitors the battery status during the charging process, automatically adjusting the charging curve, charging current, and charging pressure based on the battery's temperature and voltage.
As a charging station cable used for the charging side of the power grid, its unique structure determines that the charging characteristics are convenient connection, fast charging, and safe and convenient.
