Abstract
Abstract The invention provides an electronic monitoring device for a battery which is constructed from a plurality of units. A separate measuring circuit module is provided for each unit, and a serial databus connects the respective measuring circuit modules to one another. A central data processing unit arranged outside the battery is connected to the serial databus. Data acquisition and storage electronics are thus integrated in the battery, while the electronics for evaluating the data are arranged external to the battery, and remain when the battery is changed.
