Analyzing and controlling performance in a composite battery module

A non-transitory, computer readable medium having computer readable instructions stored thereon that, when executed by a computer, implement a method for performance analysis and use management of a battery module in an electric vehicle, wherein the battery module comprises a multitude of interconnected battery cells and a battery management system with a plurality of dedicated analysis/control units (ACUs) that analyze performance of the battery module, the ACUs being assigned to individual battery cells and the ACUs being assigned to battery blocks of the battery module, wherein the method comprises:

• measuring current and voltage of one or more of an individual battery cells and one or more battery blocks;
• calculating a charge removal from the one or more of the individual battery cells and one or more of the battery blocks;
• calculating a charge increase of the one or more of the individual battery cells and one or more of the battery blocks;
• determining the remaining charge of the one or more of the individual battery cells and one or more of the battery blocks based on the charge removal and the charge increase;
• performing failure monitoring of the one or more of the individual battery cells and one or more of the battery blocks by comparing the remaining charge and the charge removal with references levels to determine if the one or more of the individual battery cells and one or more of the battery blocks has reached a predefined level of degradation;
• based on a determination that the remaining charge of the one or more of the individual battery cells and one or more of the battery blocks is below a threshold value, activating one or more of a spare battery cell and a spare battery block of the battery module to extend the range of the electric vehicle;
• and
• transmitting a signal identifying the ACU of the battery block and the battery cell, wherein the signal is transmitted wirelessly, wherein the plurality of dedicated ACUs communicate over a same RF channel using a time domain multiple access scheme.
