  • Joint Project
  • Partner: Colibri Energy GmbH
  • Funded by BMWi
  • Duration of the project: 01.11.2020 – 21.10.2023
  • Subprojects: Implementation of a thermal cell and cell module model, optimization tool for the temperature control of battery modules in context of aging


The simplification of industrial vehicles is crucial for using them economically. The usage of Lithium-Ion Batteries brings some key advantages, like better environmental sustainability, safety and efficiency, compared to powertrains using diesel or lead-acid batteries. Unfortunately, this kind of transformation requires a big effort in development, since the existing vehicles need to be adapted. Therefore, it is a key point to consider the small sale volumes of such vehicles compared to private used electric cars.

Goals and Requirements

The main goal of the CUBE project is the creation of a modular energy storage system, to achieve a maximum in flexibility and to use this configuration in many different industrial vehicles. Here, different environmental conditions and other effects of individual stress on the battery cell should be evaluated. In this project, a thermal battery model will be implemented, to gain a deeper knowledge of the processes inside a battery module in different climate zones. Therefore, realistic measurements and aging data of the specific battery cells will be used. Subsequent to the gained information, an optimization tool is to be used to calculate and design an ideal temperature control for the used cell modules.


Further an optimized distribution of temperature sensors inside the battery will be possible, by using the data and information gained in the models. In addition, to achieve a more efficient temperature control of the cells according to the operational lifetime expectancy and the heating or cooling effort needed, the environmental and economical compromises between different methods for temperature controlling is to be be shown.
