The invention describes a charge equalizer which connects a strong with a weak cell directly via a multiplexed DC-bus and a DC/DC-converter. Due to the direct connection the energy dissipation is much lower compared to systems where the energy is only transferred from one neighbour to the next.
The direct connection only requires low voltage components which simplifies the circuit design, reduces its costs and increases the efficiency. By additional implementation of an energy buffer, the technical complexity of switching cells with differing voltage levels can be reduced and hence the design of the multiplexed DC bus can be simplified.
Researchers at the Karlsruhe Institute of Technology (KIT) have developed a novel, simple and potentially cost-saving production process for macro-porous ceramics. The process is based on the use of the capillary effect in a three phase suspension of nano- to micro-sized solid particulates. In this manner, it is possible to fabricate ceramics and polymer foams with macro-pores of diameter 50 nm or greater and narrow pore size distribution.
The presented technology is a newly developed sucrose supported synthesis of transition metal doped zinc oxide nanoparticles, which can be used as active material for the fabrication of high capacity anodes for lithium-ion batteries. The general formula of these materials is TMxZn(1-x)O (0.02 ≤ x ≤ 0.14), with the transition metal TM being, for instance, Fe or Co. The obtained nanoparticles show a homogenous particle size distribution between 20-30 nm. Anodes made of such material exhibit specific capacities exceeding 900 mAh/g,an enhanced cycling stability, as well as an improved high rate capability, particularly after applying a carbonaceous coating. Extended laboratory tests have already demonstrated the advantages of the invented material for use in lithium-ion battery anodes. Further improvement is currently under development at the MEET battery research center. PROvendis offers licenses for this invention to interested companies on behalf of the University of Muenster, Germany.
