Electric Car Charging Piles

The function of electric car charging piles is similar to that of gasoline pumps at gas stations. They can be fixed on the ground or wall and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and community parking lots or charging stations, and can be used to charge various types of electric vehicles according to different voltage levels.

The input end of the charging pile is directly connected to the AC power grid, and the output end is basically equipped with a charging plug to charge electric vehicles. Most charging piles are equipped with conventional charging and fast charging. You can use a specific charging card to swipe the card on the human-machine interface provided by the charging pile to do the corresponding charging mode, charging time, data printing and other operations. The charging post display can show the charging amount, charging time and other data.

④ For IT system distribution lines, when the first ground fault occurs, an acoustic or light signal shall be issued by the insulation monitoring device, and the faulty circuit shall be cut off by the overcurrent protection appliance or leakage current action protector when the second heterogeneous ground fault occurs;

⑤ In the lighting distribution system, lighting and socket circuits should not be supplied by the same circuit. The power supply side of the socket circuit shall be equipped with a residual current action protection device with a rated action current of 30mA;

5,Security protection function

① The AC charging pile shall be equipped with an emergency stop switch, which can be used to stop charging in an emergency by means of manual or remote communication;

② AC charging pile should have leakage protection on the output side;

③ AC charging pile should have output side over-current and short-circuit protection function;

④ AC charging posts shall be flame retardant;

6,IP protection grade

The AC charging post should comply with IP54 (outdoors) and be equipped with the necessary rain and sun protection;

7,Anti-corrosion (anti-oxidation) protection

Charging pile iron shell and exposed iron bracket, parts should take double layer anti-rust measures, non-ferrous metal shell should also have anti-oxidation protective film or anti-oxidation treatment;

8,Anti-theft protection

Anti-theft locks should be installed on the stake enclosure door, and bolts securing the AC charging stake must be installed or removed only after the enclosure door has been opened;

Q:How much time does it take a car to charge?

A:The charging time for an electric car is dependent on the size of the car's battery and the charging speed of the carport. The bigger your car's battery, the longer it takes to charge from empty to full.

A typical electric car with 60kWh battery takes about 8 hours to charge from empty to full with a 7kW charging point.

Q:The Difference Between EV Charging Stations and EV Charging Piles?

A:Electric car charging stations are stations where electric cars are charged, which are similar to gas stations today. Charging stations can be divided into four sub-modules according to their functions: distribution system, charging system, battery scheduling system and charging station monitoring system. Charging stations are generally divided into three ways to charge cars: ordinary charging, quick charging and battery replacement. The regular charging is AC charging using 220V or 380V voltage. The quick charging is mostly DC charging. The main equipment of the charging station includes charging machines, charging piles, active filter devices and power monitoring systems.

Public electric car charging stations and electric car charging piles are two concepts. Electric car charging piles are fixed on the ground, and they provide AC electric energy for electric cars with on-board chargers by using special charging interface and conduction mode. They have corresponding communication, charging and safety protection functions.
