The "black technology" of the World New Energy Automobile Conference gathers facilities such as fast power exchange and automatic charging.

  Haikou, September 17th, Zhongxin. com (Fu Yuqun) has a battery life of 10 kilometers in 40 seconds, a brand-new rapid power exchange technology, and two-way charging and discharging piles … At the technical exhibition of the 3rd World New Energy Vehicle Conference held in Hainan, a number of refreshing "black technologies" appeared at the exhibition site, involving technologies such as charging and power exchange of new energy vehicles, which attracted many people to watch and consult.

  At the current World New Energy Vehicle Conference, TELD New Energy Co., Ltd. brought intelligent flexible charging bow products, which mainly provide automatic charging for electric buses operated in cities. The product is divided into two parts: charging device and power receiving device. The charging device is installed above the bus stop, and the power receiving device is installed on the top of the bus. When the electric bus enters the bus stop, the retractable charging device can automatically charge the power receiving device.

  "This product has a relatively high charging power and a relatively fast charging speed, and the battery can be fully charged within a few minutes." Xia Xiaolong, manager of automatic charging product line of TELD New Energy Co., Ltd., introduced that in view of the problem of building charging piles in large cities at present, this product can be installed on both sides of the road by using the characteristics of fast charging to realize the combination of bus stations and charging stations. The maximum charging power of the charging bow can reach 1200kw, and the electric bus can last for 10 kilometers after charging for 40 seconds. At the same time, it can be used normally in bad weather such as typhoon, rainstorm and dust, which is very convenient.

  There is no need to get on the bridge or lift the vehicle to change electricity. The robot automatically looks for the battery to change electricity, and it can change electricity in less than 5 minutes. This is the "fully automatic miniature power exchange station" exhibited by SAIC-GM-Wuling at the 3rd World New Energy Vehicle Conference. Its light and convenient power exchange method has attracted many people to watch.

  "At present, the mainstream power exchange station on the market mainly adopts the container structure, and we use small intelligent power exchange equipment. It only takes up the space of two standard parking spaces and can be moved flexibly, which saves space very much. Power-changing vehicles do not need to go to the bridge and stop accurately. The power-changing robot can accurately identify the battery pack through visual recognition and laser positioning technology. " Huang Zupeng, senior manager of smart energy in SAIC-GM-Wuling Technology Center, said that the single power exchange time of the power exchange station is 3-5 minutes, and the use experience is equivalent to that of traditional car refueling. If the battery pack of the model on the market matches the power exchange station, it can also be applied.

  The construction of charging station is a key link to promote the development of new energy automobile industry. At the technical exhibition of the conference, State Grid exhibited a new technology, which can realize the bidirectional flow of electric energy between electric vehicles and the power grid through the intelligent interactive service platform of vehicle network, relying on bidirectional charging and discharging piles (V2G).

  "Simply put, the grid can supply power to the car, and the car can also return the electricity to the grid." According to the staff of State Grid, this V2G technology uses the mobile energy storage characteristics of the power battery to realize the charging and discharging of the vehicle-mounted power battery according to the power grid demand through bidirectional charging and discharging piles, that is, to guide users to discharge at the peak of the power grid load and charge at the low load, so as to reduce the use cost of new energy vehicles for users.
