20120313560 | HIGH-CURRENT BATTERY SYSTEM AND METHOD FOR CONTROLLING A HIGH-CURRENT BATTERY SYSTEM - 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. For each bypass battery module, the battery system monitoring electronics unit incorporates a module monitoring unit which monitors the associated battery module and detects a fault state of the module. Upon detection of a fault state of a battery module by one of the module monitoring units, the battery system monitoring electronics unit measures the current flow in the operating current line and switches the bypass switch of the battery module in question from the normal operating position into the bypass position at a time at which the current flow in the operating current line is less than a predetermined limit value. | 12-13-2012 |
