Watema three yuan battery technology and battery recovery system have long been reserved

Watma has been exploring the secondary use of the power lithium-ion battery in 2012, which uses the retired electric vehicle power lithium-ion battery, and built a 3MW lithium iron phosphate ion battery energy storage power station. Similarly, from 2012 Start investment in three yuan material batteries. According to the development of new energy vehicles, it is estimated that by 2020, pure electric vehicles and plug-in hybrid vehicles have reached 2 million, with more than 5 million units.

Under the huge incremental space, with the end of the lithium-ion battery life, the power lithium ion battery on the electric vehicle will be placed in a large number, how these batteries are dealing with a large problem facing the industry, as well How is the Watma planning? Battery recycling system has long been reserves deputy general manager of Shenzhen Watma Battery Co., Ltd. (the Institute Dean) Rao Minmin said in the introduction of the first electric network, in fact, Watma has already explored dynamic lithium in 2012.

The route, method of the ion battery, using the retired electric vehicle power lithium-ion battery, built a 3MW lithium iron phosphate ion battery energy storage power station, laid the foundation for the tradenses of the waste power storage battery. At the same time, Watma has also vigorously develops energy storage products in the process of pushing new energy vehicle power lithium-ion batteries. In addition to the development of the energy storage power station, Watma has also successfully developed 1200kwh, 750kwh, 640kWh mobile filling tram (used for electric vehicles, energy storage capacity, etc.

). In the future, it is considered to use waste dynamic lithium-ion batteries to mobile supplementary vehicles, and further explore the application of waste power lithium ion batteries in the energy storage system. On the other hand, Watma will use advanced production technology, short-range, efficient recycling of elements such as nickel, cobalt, manganese, lithium in the battery, and then through the company's original "directional circulation" model and the world's leading "reverse product positioning design" Techniques, adjust the multi-element component matching ratio by formulation reduction technology, supplemented by the synthetic solution, and realizes the "directional circulation" from the waste battery to the battery material, thereby producing the battery from manufacturing, consumption to the recovery of the entire circulation Organic integration.

Taking into account the battery safety and energy density exploration of the three-yuan battery technology since 2008, Watma has accumulated more than 7 years of new energy vehicle operations related experience, equipped with Watma battery more than 30,000 Taiwan set, single operation mileage is 430,000 km. In terms of battery fast charge, Watema phosphate ion battery has also been charged for 10 minutes to charge 80% power, and it has been operated in a large range. The same is based on safety, the current basic all of Watma's basics is a lithium iron ion battery, but in terms of three-yuan materials, Rao Minmin said that the advantage of energy density is actually Watma.

From 2012, I started to invest in research and development for many years, but I have not widely promoted, and I will have a wide range of improvement. Similarly, he also said that Watma uses a composite material as a battery positive and negative electrode material to enhance the battery energy density of about 20%. At present, Watema phosphate ion battery monomer energy density can reach 180-200 kWh / kg, 100KWH / kg can be achieved after the battery is set.

In terms of security, Watema's power lithium-ion battery produced from the monomer, module to the grouping system until the installed operation, forms a full range of detection, through large data platform, monitoring each car. At present, the Watma cylindrical ferric lithium ion battery structure introduces the joining ventilation center tube, solving the balance problem of battery internal pressure, prevents the explosion of the battery; new security valves in combination cap, effective control of the internal pressure of the battery in normal safety Within the range value, prevent explosion risk; the battery pack uses specially designed composite panels and PCB protection circuits, even if the battery's use environment also allows all batteries in the same environment, even balanced increases the resistance to make the battery. The load being carried is the same, and there is an environmental difference between the battery.

In addition, Watma low temperature battery is not only successful in Xinjiang Urumqi, but has passed the authority of the Information Industry Department of Chemical Physics Power Product Quality Supervision and Inspection Center, indicating that my country's northern region promotes pure electric cars have preliminary Technical solution. Break through the limit of charging and discharge of less than 20 degrees above zero, can be realized at minus 35 degrees normal discharge and zero 20 degrees normal charging. Finally, when I talk about the new national standard of the battery, Rao Dingyi believes that the implementation of the new national standard has added high temperature and low temperature and soaking of the battery cell module, in fact, this improves the battery access standard, the battery safety Demand.

But the healthy development of the industry is also advantageous, and the use of the industry's standardization is also very large.
