The charging pile is so built, can the electric car be safely eaten?

The pile is outside, the car is at home, and the car has to find a pile. There is a mismatch between supply and demand. No matter how many charging piles are built, it will not make electric vehicles easy to use, but will only increase empty piles.

The latest data shows that the number of new energy vehicles in China exceeds 4.5 million, and the number of public charging piles is 1, 4 1, 000. Although the vehicle-pile ratio did not reach the desired 1: 1, it also reached 3: 1, which should be a comfortable support for new energy vehicles. However, in fact, most of us think that charging piles are not enough and charging is troublesome. Is this a subjective illusion? I don't think so.

A while ago, we went out to do a field survey in a city of 10, and found that there are several common pain points in the construction of charging piles in some big cities:

1, charging and parking charges are separated and charged repeatedly. Most trams are required to leave immediately after charging and then stop charging;

2. The matching degree between supply and demand of electric piles is low.

3. The management of electric piles is not in place, the oil trucks in busy places occupy a serious position, the places that are not busy are not positioned accurately, and the environment is dirty.

These three factors add up. In the actual car use, the car mainly takes time to charge, and there is a risk that it can't find a place to charge. After charging, it will drive away, and the experience will naturally not be good.

This mode is the same as our fuel car, which leads us to hope that the charging speed is as fast as possible, and some people even suggest that it will be full in 5 minutes! In fact, at least the current technology and power supply strength are not allowed.

Then let's see if we can find a more suitable charging mode for electric vehicles.

Recently released "202 1-2035 New Energy Automobile Industry Plan" not only mentioned speeding up the construction of charging and replacing infrastructure, but also emphasized the scientific layout of infrastructure, strengthened construction planning and overall coordination, and introduced the concept of system.

The direction of charging pile construction guided by planning has changed, giving up the pursuit of charging pile matching ratio and turning to scene-based energy supplement guidance. In the city, develop a charging service mode in residential areas with slow charging as the mainstay and emergency quick charging as the supplement, that is, charge wherever commuting stops at ordinary times to improve convenience; In expressway and expressway, accelerate the formation of a charging network that is moderately advanced, fast charging first, supplemented by slow charging, and public in urban and rural areas to meet the needs of long-distance driving; Of course, technological innovation will continue, and the research and development of new charging technologies such as intelligent and orderly charging, high-power charging and wireless charging will be strengthened.

If you have an electric car, what is the comfortable charging experience? Usually commuting in the city, you can use the slow charging pile in your home or unit parking lot to charge, without taking time out to charge. This usage saves more time and money than a fuel truck. When traveling far away, first charge slowly all night, and on the way, use a high-speed fast charging pile to replenish the power to solve the mileage anxiety. When you arrive at your destination, fill it with a slow charging pile, and the basic experience is close to that of a tanker.

If this effect is achieved, can the electric car be safely eaten? You might say that we still have to solve the problems of battery safety and resource recovery. Let's put these aside for a while, and today we will only discuss the charging infrastructure. The problem is that there is still a long way to go from the status quo to the ideal effect. The difficulty lies in improving the matching degree between supply and demand of charging piles, including the orderly use of fast charging piles in expressway during rush hours and the popularization of slow charging piles in cities.

At present, expressway adopts the way of supporting service areas, and the number of four charging piles in each service area can be handled at ordinary times. Once the travel peak, even the service area can't get in, how to solve the demand for quick replenishment? On the one hand, increase the proportion of supporting facilities, on the other hand, can intelligent data management be used to promote charging reservation and alleviate the congestion of power renewal?

At present, the popularization progress of slow filling piles is much lower than the construction speed of public charging piles. For example, the number of charging piles in Xiamen exceeds 6,000, while the number of charging meters used by residents in the community is only 809. In order to promote the popularization of slow filling piles, the policy should be more detailed and stick to the ground. At present, there are still many places where the property management of residential buildings and office buildings has not been opened, and the application for privately installed electric piles has been blocked; In the case that the proportion of parking spaces owned by individuals is not high, it is the basic condition to realize the enjoyment of one car and one car, but the supporting mechanism has not yet begun to land. In Fuzhou, we conducted a field survey on a large-scale new building that was delivered on 20 19. It is 100, which does not meet the requirement of Fujian Province that the proportion of non-fixed property rights and public parking spaces is not less than 20%. 7kW slow charging pile is not a mandatory requirement for manufacturers to sell cars. Some manufacturers are equipped with 220V chargers, which have low charging efficiency and no charging lock protection. Every problem is a mountain, and the state is different in different places, so it can't be cut across the board.

In fact, I personally think that 100% is difficult to solve the above problems. According to different resource conditions, urban solutions and new energy routes should be different. In short, we should avoid the past one-size-fits-all and one-party management.

Switching from a fuel car to an electric car, although the product form is still four wheels and a sofa, the actual use mode may need to be adjusted. We should also look at electric vehicles with a rational eye, actively explore the correct opening mode of electric vehicles, and avoid indirectly denying the value and advantages of electrification by the standard of fuel vehicles.
