With the rapid increase of the penetration rate of new energy vehicles, the number of charging piles is far less than that of new energy vehicles. As a "good medicine" to solve the anxiety of new energy vehicle owners, many new energy vehicle owners only know "charging" about the charging pile. The following is the knowledge about charging piles.
●What is a charging pile？
The function of the charging pile is similar to that of the fuel dispenser in the gas station. It is a kind of equipment for daily energy supplement of electric vehicles. The charging pile can be installed on the wall for small power and on the ground for large power according to the power and volume. The equipment is commonly used in public places (public buildings, shopping malls, public parking lots, etc.), parking lots in residential areas and professional charging dedicated parking lots. At present, most of the common charging equipment are equipment that meet the new national standard in 2015. The charging guns are of uniform specifications and can charge electric vehicles of different brands and models. According to the output power, the charging pile is generally divided into two charging modes: AC slow charging and DC fast charging. The user can use the specific charging card provided by the manufacturer to swipe the card on the charging pile, or scan the QR code on the pile through a professional app or small program. In the charging process, users can query the charging power, cost, charging time and other data through the human-computer interaction screen on the charging pile or the mobile phone client, and conduct the corresponding cost settlement and parking voucher printing after the charging is completed.
●How to classify charging piles?
1.According to the installation method, it can be divided into floor type charging pile and wall mounted charging pile. The floor type charging pile is suitable for installation in the parking space not close to the wall. The wall mounted charging pile is suitable for installation in the parking space near the wall
2.According to the installation location, it can be divided into public charging pile and special charging pile. The public charging pile is a charging pile built in a public parking lot (garage) combined with a parking lot to provide public charging services for social vehicles. The special charging pile is the charging pile used by the internal personnel of the construction unit (enterprise) in its own parking lot (garage). The self use charging pile is a charging pile built in the self owned parking space (garage) to provide charging for private users. The charging pile is generally constructed in combination with the parking space of the parking lot (garage). The protection level of the charging pile installed outdoors shall not be lower than IP54. The protection grade of the charging pile installed indoors shall not be lower than IP32.
3.According to the number of charging interfaces, it can be divided into one charging and one multi charging.
4.According to the charging mode, the charging pile (plug) can be divided into DC charging pile (plug), AC charging pile (plug) and AC / DC integrated charging pile (plug).
●Safety requirements for charging pile
1. The substation shall be provided with safety fence, warning board, safety signal lamp and alarm bell。
2. Warning signs of "Stop, High Voltage Danger" shall be hung outside the high voltage distribution room and transformer room or on the safety column of the substation. The warning signs must face the outside of the fence.
3. The high-voltage power distribution device shall have obvious operation instructions. The grounding point of the equipment shall be clearly marked.
4. There shall be obvious signs of "Safe Passage" or "Safe Exit" in the room.
