The function of the new energy vehicle charging pile is similar to the fuel dispenser in the gas station. It can be fixed on the ground or wall and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. The voltage level of charging various models of electric vehicles. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging the electric vehicle. Charging piles generally provide two charging methods: conventional charging and fast charging. People can use a specific charging card to swipe the card on the human-computer interaction interface provided by the charging pile to perform operations such as corresponding charging methods, charging time, and cost data printing. The charging pile display can display data such as charging amount, cost, charging time and so on.
Did you know that charging piles for new energy vehicles are universal?
With the progress of people’s life, consumers have higher and higher requirements for automobiles, especially new energy vehicles. When consumers buy new energy vehicles, the first thing they should pay attention to is the battery and battery life of new energy vehicles. , and then there is the issue of car charging. The core of the charging national standard revision plan officially released this year is to standardize and unify the charging piles of new energy vehicles, and the charging sockets of different models will be unified.
According to the new national standard, the standard of charging plugs for different models in the future will be the same. Xu Xinchao said, “Although there will be differences in voltage and power, they can theoretically be used in the same charging pile. In addition, the new national standard attaches great importance to the safety of charging piles, which has always been the top priority. The standardized new energy The car charging pile will automatically power off after charging, and make breakthroughs in insulation in rainy days and avoid electric shock, so as to avoid unnecessary dangers for new energy vehicle owners during the charging process.”
However, the introduction of new standards could lead to the obsolescence of a large number of existing charging facilities. Because it involves the interests of many enterprises, it has also become the reason for the difficulty in introducing the new national standard.
In 2006, China issued the “General Requirements for Electric Vehicle Conductive Charging Plugs, Sockets, Vehicle Couplers and Vehicle Jacks” (GB/T 20234-2006). This national recommended standard specifies the charging current as 16A, 32A, The connection classification method of 250A AC and 400A DC mainly draws on the standard proposed by the International Electrotechnical Commission (IEC) in 2003, but this standard does not specify the number of connection pins, physical size and interface definition of the charging interface. In 2011, China launched the GB/T 20234-2011 national recommended standard.
my country’s electric vehicle charging interface and communication protocol standards GB/T 20234-2011 include: GB/T 20234.1-2011 “Electric Vehicle Conductive Charging Connection Device Part 1 General Requirements”, GB/T 20234.2-2011 “Electric Vehicle Conductive Charging Connecting Device Part 2 AC Charging Interface”, GB/T 20234.3-2011 “Connecting Device for Electric Vehicle Conductive Charging Part 3 DC Charging Interface”, GB/T 27930-2011 “Off-Board Conductive Charger and Battery for Electric Vehicles” Communication Protocols Between Management Systems. The release of these four standards marks that my country’s charging interface has achieved a unified standard at the national level.
After the release of the national standard, the newly built charging facilities have been manufactured and installed in accordance with the national standard, and the original charging facilities are gradually updating the interface to achieve the unification of the standard.
