Electric environment: The charging pile needs to be connected to the power grid for charging, so there needs to be a stable and reliable power supply. The installation site should have reliable power equipment and power lines to meet the electricity demand of the charging pile. Infrastructure: Charging pile installation requires appropriate infrastructure, including parking lots or parking Spaces. The parking space where charging piles are installed should have certain space and convenience to facilitate the parking of vehicles and access to charging equipment.
Ground conditions: The ground for installing charging piles must be smooth, solid, and have good drainage conditions. This is to ensure the stability and safety of the charging pile. Building conditions: If the charging pile is installed inside or near the building, there needs to be enough space to place the charging pile equipment, and the problems of cable wiring and heat dissipation should be taken into account.
What are the installation conditions of charging piles? The installation conditions of the charging pile include the following: Confirm the charging conditions: First confirmWhether there is a fixed parking space in the community, and whether the parking space can be connected to the national grid line. If the community does not allow the installation of charging piles, other conditions do not need to be considered. Property consent and cooperation: The installation of charging piles requires the consent of the property, which requires communication between the owner and the property.
- Installation vertical inclination: not more than 5%. - Equipment installation location: there shall be no explosive dangerous media, and the surrounding media shall not contain harmful gases and conductive media that corrode metal and destroy insulation. Dc charging pile installation standard: - Power input voltage: three-phase four-wire 380VAC±15%, frequency 50Hz±5%. - Charging object: Meet specific battery standard requirements.
2, among them, for the need for new energy vehicles, the person in charge of the document office of the Shenzhen Municipal Legal Affairs Office said that to open a network car, there must be a pure electric vehicle. 3, from the point of view of operating costs, the cost of pure electric vehicles is much lower than that of fuel vehicles, but the factor to be considered is whether the charging facilities can meet daily needs. However, with the improvement of charging facilities and the strengthening of vehicle endurance, it is believed that more cities will introduce similar regulations in the near future.
4, fuel vehicles can not be changed to operate, Shenzhen's operating taxis have all been cutSwitch to new energy electric vehicles. It is a trend that fuel vehicle operating vehicles are gradually replaced by pure electric operating vehicles. The cost of using pure electric vehicles is much lower than that of fuel vehicles. In order to reduce their operating costs, many drivers will take the initiative to choose to use pure electric vehicles to operate.
5, oil change and other maintenance, and the maintenance cost of pure electric vehicles is relatively low. In short, pure electric vehicles have become the preferred model of online car booking, which is the direction of sustainable development of urban transportation in the future. Their environmental protection, quiet, energy saving and other advantages also meet the needs of modern people for comfort and environmental protection. With the continuous improvement of battery technologyWith the improvement of charging facilities, the market demand for pure electric vehicles will become more vigorous and become the mainstream of urban rental services.
1, the first battery life is false. Although the range of new energy vehicles is getting higher and higher, in fact, the range marked by many manufacturers has a great difference with the actual range, especially for the northern region.
2, the virtual label is serious. First of all, we know that the official pure electric vehicle NEDC range is the range obtained under certain conditions, which is not suitable for all automotive environments. It is equivalent to the theoretical mileage data on the frame, which is far from the actual mileage. [2] People's anxiety actually comes from uncertainty about the future. The petrol car has 20 litres of fuel, that is to say, there is 20 litres of fuel in the tank, 100% sure.
3, electric vehicles have broken through 800km, or can not eliminate mileage anxiety, which is why? There's no place to charge it all the time,The battery of an electric vehicle has many uncertainties, which will cause the car to be unable to start because of the cold weather, leading to the reduction of the battery life, and will cause the battery to explode and burn in the summer because of the high temperature, which is life-threatening, and the battery has no good stability, so it is not suitable for long-distance driving. In addition to the problem of charging conditions, many people will be anxious about the remaining power of electric vehicles in the end. The least trustworthy thing in the world, besides a man's mouth, is probably the remaining battery power of an electric car. Of course, the remaining power is not accurate for a reason, and is too complicated by various factors. One is to form a batteryThe material is too complex, different materials of course have personality, the standard of electricity measurement is difficult to tune.
5, if the fuel truck pile endurance, pile to 5,000 kilometers are no problem, but that is a problem, and the safety factor is also reduced. The security here is not only the safety of gasoline, mainly it is also easy to steal oil. The big truck has an 800L tank, so the truck has too many gas rats. Therefore, there is a conclusion here, that is, even if the tram can travel more than 1000 kilometers, in the endurance, it is not better than the oil car.
6, in addition to charging conditions, many people on the remaining power of electric vehiclesAccuracy is also a concern. The accuracy of the remaining battery capacity is affected by many factors, including the battery material, the battery pack measurement error, and so on. At present, only a few electric vehicle companies can accurately calibrate the remaining battery power. Due to environmental factors, especially the halving of the winter range, consumers are skeptical about the range of electric vehicles.
