New energy vehicle bus "greening" Tianjin


Clean, tidy, no noise, and comfortable inside the cabin... On the morning of April 3rd, 2014, the reporter took an air-conditioned new energy bus from Tianjin 638 Road to experience. It is understood that after the 120 kilometers of the new energy electric bus operation, it needs to replace the battery. In Tianjin Haitai electric vehicle charging and swapping station, the reporter saw that the station uses automatic changing robots to achieve accurate positioning and rapid and efficient battery replacement.

In 2015, Tianjin promoted 12,000 new energy vehicles. “At present, the city has cumulatively operated 1,319 energy-saving and new energy vehicles, operated 10 stations for charging and changing, and 471 charging stations.” said Li Pengyue, chief engineer of the Tianjin Science and Technology Commission. After Tianjin was approved in 2013 for a new round of pilot cities for the promotion and application of new energy vehicles, the municipal government has set a total target of promoting 12,000 new energy vehicles in eight areas by 2015. "Up to April, 220 pure electric buses were operated on 8 bus routes." Li Pengyue said that in 2014, it will fight for 600 additional pure-electric buses, bringing the total to 800. The field of postal express delivery actively promoted new energy vehicles to replace motorized tricycles and organized Qingyuan to develop a mini pure electric postal van for five months. On March 21st, the first batch of 20 vehicles has been put into trial operation, and it will gradually scale up after May 1st to expand the number of applications. "Enterprises and private purchases of new energy vehicles also achieved a zero breakthrough."

Li Pengyue stated that Tianjin has already established a policy of subsidizing local car purchases in accordance with state subsidies 1:1. At present, according to the target of 12,000 promotion and application, a budget of 2.2 billion yuan has been implemented for local financial subsidies, and it is actively studying subsidies for the operation of infrastructure.

It is understood that in recent days, Tianjin has implemented the implementation of the minibus total control and vehicle limit line, which clearly defined the new energy vehicles directly on the card, the new energy postal car unlimited line of related policies.

A single charge can ensure that the bus travels 120 kilometers. On the morning of April 3, 2014, the reporter saw at the Haitai electric vehicle charging and replacing station in Binhai Hi-tech Zone, Tianjin that two “workers” are “changing robots”. Replace the battery for the bus.

"After the bus enters the track, the two power-switching robots will start simultaneously." According to Cheng Xinxin, a staff member of the Tianjin Electric Power Company, along the linear track laid between the vehicle and the charging rack, the robot will be installed on the battery The sensor signal on the box removes the charged battery on the charging rack, and then removes the battery box that needs to be charged from the opposite side of the charging rack, and automatically rotates the battery box 180 degrees to send the battery box that is fully charged. Into the car battery box location, the other side of the need to charge the battery box into the charging stand for charging. "Every electric bus has 9 batteries per vehicle. The entire battery replacement process takes about 8 to 10 minutes. A single charge can ensure that the bus travels 120 kilometers."

"The company adopts the battery lease settlement mode. The users pay the lease fee in installments according to the power consumption. The battery life is directly linked to the rental income." Zou Yufeng, deputy general manager of Tianjin Lishen Power Battery System Co., Ltd. introduced the battery used up by the car. There is usually 80% of energy, and other customers can also use the cascade. "Leading the battery can save the cost in 4 years. Generally, it can be used for 7 to 8 years. Of course, the customer's use conditions are different and there is no absolute value. That is, long battery life can make money."

It is understood that Tianjin has gathered Lieshen, BAK, Gateway, Zhongju and other well-known battery companies, as well as foreign-funded enterprises in the United States, Japan, South Korea, and Europe. The total number of foreign-funded enterprises has reached more than 10, and the degree of industrial aggregation in the country is relatively high. Bamo, Baterui, Jinniu, Dongjiu and other enterprises can provide all the supporting materials for battery materials. The output value of lithium-ion battery industry is nearly 10 billion yuan.

At present, Tianjin New Energy Automobile has applied Yutong, Ankai, BYD, Jianghuai and other 10 companies' products, and the market share of other provinces and cities has reached more than 90%.

2015, Tianjin electric buses will reach 2000 <br> <br> It is understood, August 8, 2012, the first batch of Tianjin Bus Group 40 change in electric buses put into demonstration operation. From August 8, 2012 to the end of February 2014, 40 pure electric buses operated for a period of one year. Their total mileage exceeded 3.6 million kilometers, carrying 7.5 million passengers, and the maximum mileage of bicycles exceeded 100,000 kilometers. 40 pure electric buses save more than 1 million liters of fuel and reduce carbon emissions by 7.8 million tons.

According to Zhang Yaguang, deputy general manager of Tianjin Public Transport Group, according to the plan, by 2015, the scale of Tianjin pure electric buses will reach 2,000. According to the technical route of "replacement, integration, adaptation to local conditions, recharging, recharging, and replacement," this year, the power company will build two replacement stations and increase the number of bus-changing buses. At the same time, charging stations will also be built according to local conditions to meet the demand for the development of pure electric buses in Tianjin.
