In places where space resources and electric vehicle ownership are contradictory in first-tier cities, it is difficult to realize a vehicle and the shared charging outlook is infinitely optimistic.
However, this kind of ideal based on the existing open charging resources of individual charging piles or enterprises and institutions still requires some people to pay for expensive charging equipment. In order to realize the shared intelligence of piles, the public need behind the complex systems including payment, ease of use, interconnection and other technical support, and the accompanying increase in costs.
Introduce a low cost.
Recently, we found in the Shuangqing Building where the Tsinghua Energy Internet Research Institute was located that six "energy Internet" outlets were actively installed in the office parking lot. The outlets are similar in appearance to ordinary outlets but can be used to charge electric vehicles.
We contacted the inventor of the socket, Zhang Luoping, a researcher at the Tsinghua Energy Internet Research Institute. According to its introduction, the energy Internet socket works in the same way as a slow-charged 3.5-kilowatt pile and supports the slow charging of an electric car 16A. Electric car owners can use their own portable electric car charger to achieve charging.
Unlike ordinary sockets, this small socket integrates metering functions. In order to save the hardware cost, the electricity meter screen mostly saves, but after scanning the two-dimensional code on the socket, can also see the on-off state of the electricity meter, voltage, electric current, power, charge quantity and so on information. After the online payment is successful, the outlet starts to power on.
According to Zhang Luoping, because each "energy Internet outlet" can only be limited to charging an electric vehicle, it is guaranteed that no fire will be caused by overloaded electric wires.
The electric vehicle portable charger has been used as a supplement to electric vehicle charging piles in the past. When the owner encounters a nearby pile, he or she can access the air conditioning outlet (usually 16A) of the street shop to achieve emergency power supply.
However, Zhang Luoping believes that the plug-in model should be the mainstream of shared charging. This model can solve the current difficult to install charging piles difficult to achieve profitability, "cost is 30 times lower, profitability is equivalent to increase 30 times," and the current charging pile installation Coordinating parties and high electrification requirements are high. In the installation process, the outlet “because the power is small, is almost the power of an air conditioner, and the dispersed installation does not require power line modification†and can be quickly rolled out.
Tsinghua Energy Internet has always been committed to energy-related Internet-related hardware and software innovations. The innovation of the energy internet outlet is also inseparable from the energy internet cloud platform supporting its operation. The socket owner can formulate a variety of charging rules through the Tsinghua Energy Internet cloud platform to easily realize the operation of charging facilities.
Zhang Luoping stated that since the power usage of each “Internet power outlet†is monitored by the cloud platform, if the power supply capacity is insufficient, the “energy internet outlet†can help the power grid control shut down some power loads that are not needed, and improve the dynamic balance of the power grid. ability. Therefore, the number of outlets can even be "infinitely more", and the charging convenience experience will become better and better.
The president of the Tsinghua Energy Internet Research Institute once stated that in the operation of the energy internet platform, their goal is to establish energy “Taobaoâ€, reduce market barriers, and cultivate market players.
Therefore, compared with charging operators, Zhang Luoping is more willing to address each owner who owns an outlet as a “retail power†shop owner, “solving the problem of small-paying users’ use of power resources, and realizing self-service power consumption services in public places. New business model for increasing load and increasing electricity sales."
In addition to the 16A electric vehicle sharing socket, Zhang Luoping also developed a 10A socket product for two-wheel electric vehicles and mobile phone charging, completing the upgrade iterations of the products on the market that require manual control of the power switch.
Zhang Luoping also said that just yesterday, Guilin High-tech Zone decided to adopt this new technology, carry out demonstrations, and install "energy Internet outlets" charging facilities, including bicycle shelters, for each parking space in the High-tech Zone.
Shared charging requires new innovations. From the perspective of the development of any shared things, the most fundamental possibility is to lower the cost of carriers first. Therefore, some people chose to jump out of the "pile" carrier.
This product response time is shorter than resistive tonch screen's with a good touch.It is widely used to Phone,Tablet,E-book,gaming device by hands holding,Touch Monitor,GPS,All-In-One and so on.GreenTouch projected capacitive touch technology is with fast and sensitive response, the design with frame (without frame is optional) makes it looks professional and generous. The model is designed for high-intensity and high-frequency business environments.
