Power battery cascade utilization will become industry hotspot

  With the explosive growth in new energy vehicles, 4, 5 years later, will no doubt have a lot of retired power battery. Accompanied by is, the electric car with power battery cascade utilization also into industry hotspot gradually.
  Four years later, a large number of power battery will be retired cascade utilization needs to be broken
  Under the time background of green environmental protection, new energy vehicles into rapid development. In 2015, the annual cumulative production of new energy vehicles in China, 379000, year-on-year growth of 4 times.
  With the explosive growth in new energy vehicles, 4, 5 years later, will no doubt have a lot of retired power battery. Accompanied by is, the electric car with power battery cascade utilization also into industry hotspot gradually.
  Power battery cascade use of the space is larger
  Reporters from the Chinese chemical and physical power industry association, 2015 local production about 16 gigawatts of power battery, is expected to reach 32 gw at the end of 2016.
  According to forecast of China automotive technology research center, in 2020, our country electric power battery scrap amount will reach 120000-170000 tons scale. If these retired directly used for recycling batteries, not wasteful. And the function of the effective ways to play to the largest is the cascade utilization, then as a resource recycling.
  As the Chinese academy of engineering academician Yang said: "these useless power battery manufacturing process is advanced, even scrapped after security and performance of remains high, it is necessary to adopt the way of cascade utilization to realize the maximization of the resource utilization of waste power battery."
  It is understood that at present domestic has quite a few old power battery after detection, restructuring, applied to the cases in the field of energy storage. Previously, new energy material and technology laboratory of Peking University doctoral tutor the professor lu told reporters that hundreds of electric buses, the 2008 Olympic Games was put into operation after 3 years for wind power and solar energy storage.
  Interview, many people think that, given the strong development tendency of the future electric cars, also will bring power battery of cascade utilization of blue ocean.
  Battery recycling remained technical barriers
  Power battery according to the national standard in service life, the new energy car break down, and the use of great capacity and a broad space. Will be retired power battery application in energy storage, in terms of both economy and environmental protection, is a good choice.
  Retired batteries, however, is not like imagination, the combination can, there are some obstacles in technology. Cascade utilization, the battery consistency difference compared with new batteries, the use of group has caused great obstacles. At the same time, the battery capacity, voltage, resistance and so on in cascade utilization will bluff type formed under a few cycles fall, caused great difficulty for later use.
  In order to promote the cascade utilization of power battery, in addition to the national policy level to encourage support, many local governments are actively exploring.
  Policies, such as Shanghai auto enterprises power battery recycling government subsidy 1000 yuan/set; Shenzhen set up power battery using and recycling system, each car manufacturer sold out 600 yuan, the government took out 300 yuan, used for recovery of power battery, preliminary set up the system of battery recycling.
  It is understood that at present, including the state grid, local governments, such as battery enterprises are carrying out a research into the rundle power battery recycling. Such as its Chinese henan electric power company was built in 2013 micro grid system, and build a set of power battery sorting, assessment, with the standardization of the process. Public information, the project is located in zhengzhou city jianshan true type transmission line test base, is the first domestic real mixed micro grid system based on former power battery, the current system is running in good condition.
  "Retired battery recycling in the smaller family storage battery, UPS (uninterruptible power system) is feasible." Chinese academy of sciences, institute of electrical energy storage technologies Chen Yong led the team of her said, "but for large energy storage power station, want to consider circulating sex, security, among them there are nonlinear changes, can increase the probability of accident, at the same time management costs will be high. However, cascade utilization of power battery is not the ultimate solution, we also need to actively to develop a new type of environmentally friendly power battery recycling easily."
