German scientists developed the lightest than energy as much as 230 WH/kg of lithium battery system

Germany Saxony - thuringia lightweight release information R&D alliance, the alliance has developed the world's light The lithium battery System, and from the system level, the specific energy is as high as 230 WH/kg.

From the German city of dresden (Saxony) researchers have developed the world's most light of the application of lithium-ion technology The battery System. Lightweight dresden university of technology and synthetic materials technology research institute, a branch office, called Scaba. Sebastian Prengel Scaba director said, they have successfully on the basis of the structure of space, into the bit Tesla car more than 30% of the battery cell. The research project is with (thuringia) world Envites Energy institutions the colla boration. The alliance by Scaba cooperate with Envites Energy, wanting to apply research results and on the standardized mass production of the battery, so that customers can freely select the battery type and battery manufacturers.

In a lightweight design patents, on the basis of Lithium electricity Pools are assembled into a variety of different geometric shapes. The lightweight design of the structure of the cell structure is novel, and a high safety factor. So the lithium battery is not only the geometric shapes and variable voltage level. In addition, the founder of institute of Scaba Marco Zichner said: "our skilled safely handle with the rated voltage 1000 v high voltage battery technology", and the battery system than energy has proved the 230 WH/kg.

Active and passive safety are higher high voltage battery systems

In order to reduce the types of parts and improve production efficiency, the alliance is used in production of mixed plastic and metal parts are finished in advance. And in the development of high voltage battery systems, automotive active safety and passive safety is the most need of tried to think about it. Union spent a lot of energy to research and development, for example, a fault current can be away for the fiber composite materials shell of intrusion detection. Alliance developed with insulation fault detection and intermediate circuit of voltage monitoring system has been meet ASIL - D and SILLevel3 standards.

In addition, there is a kind of independent research and development of interdisciplinary security design scheme is also obtained the patent. Adopts the patent technology can in the case of necessary, safely and quickly to cut off the high voltage. Another kind of integration results is developed by the Envites Energy company "Dry Cloud system". The system can eliminate the extreme battery fire danger. Scaba institute believes that this kind of flexible lithium ion high-voltage battery system can be applied to electric vehicles, automobile and medical equipment of the grid.
