Patent number: 8981683Abstract: The present invention relates to a high power battery system having a battery system monitoring electronics and battery modules being electrically connected in series via an operating current line. At least one battery module is a bypass battery module comprising a bypass switch and a bypass line for electrically bypassing the battery module. For each bypass battery module a module monitoring unit of the monitoring electronics monitors the assigned battery module and detects a fault state. In the fault state, the battery system monitoring electronics measures the current flow in the operating current line connecting the battery modules and switches the bypass switch of the bypass battery module concerned from a normal operating position to a bypass position at a time when the current flow in the operating current line is lower than a predetermined limit value.Type: GrantFiled: February 8, 2011Date of Patent: March 17, 2015Assignee: Alevo Research AGInventors: Guenther Hambitzer, Joachim Heitbaum, Markus Borck, Christiane Ripp

Publication number: 20120313560Abstract: The present invention relates to a high-current battery system in which a high operating current flows, in particular for vehicle drives. The high-current battery system has a battery system monitoring electronics unit and a plurality of battery modules, each module including at least one rechargeable battery cell and being electrically connected in series by means of an operating current line such that an operating current flows through the operating current line during operation. At least one of the battery modules is designed as a bypass battery module which comprises a bypass switch and a bypass line, which are designed and disposed such that the battery module is electrically bridged by the bypass line after the bypass switch is switched from a normal operating position into a bypass position, so that the operating current flows through the bypass line.Type: ApplicationFiled: February 8, 2011Publication date: December 13, 2012Applicant: fortu Intellectual Property AGInventors: Guenther Hambitzer, Joachim Heitbaum, Markus Borck, Christiane Ripp

Patent number: 5656391Abstract: Electromechanical alkali metal cell with a positive electrode (6), which has a metal substrate (4) and an active mass (5) connected to the substrate, the active mass (5) containing a complex metal oxide with the general formula A.sub.x M.sub.y O.sub.z, in which A denotes the alkali metal, M a transition metal and O oxygen. With simple manufacture high long-term stability of such an electrode is achieved by the fact that the positive electrode (6) is a composite electrode, in which the active mass (5) is connected without an organic binder directly to the substrate (4), the active mass and its connection to the substrate being produced by heating an electrode base containing the transition metal M in contact with an inorganic compound of the alkali metal with conversion of a surface layer of the base with the alkali metal compound to the complex metal oxide (FIG. 4 ).Type: GrantFiled: May 24, 1995Date of Patent: August 12, 1997Inventors: Gunther Hambitzer, Joachim Heitbaum

Patent number: 5087373Abstract: In a process of removing complexly bound titanium and/or zirconium from acid aqueous solutions the solution which contains the complexly bound titanium and/or zirconium is conditioned in that its pH value is raised to at least 8, any precipitate thus formed is removed and the solution thus treated is passed through an ion exchange plant comprising a cation exchange material and an anion exchange material. The solution is preferably passed through an ion exchange plant which contains the cation exchange material in the H.sup.+ form and the anion exchange material in the OH.sup.- form. The process is particularly intended for the treatment of solutions obtained by the chemical treatment of surfaces preferably of metals, which solutions contain titanium and/or zirconium in the form of fluoro complexes.Type: GrantFiled: May 29, 1991Date of Patent: February 11, 1992Assignee: Metallgesellschaft AktiengesellschaftInventors: Thomas Kolberg, Horst Gehmecker, Joachim Heitbaum
