Tempering lithium-ion batteries correctly

The seminar language is German. The performance and ageing behaviour of the battery systems (battery cells) is of central importance for the range, charging time and service life of electric vehicles. Lithium-ion batteries (LIB) have established themselves as storage technology for e-mobility due to numerous advantages. The performance of these battery systems is significantly influenced by temperature. Low temperatures lead to a loss of performance and can trigger degradation processes (ageing) that reduce the service life. Elevated temperatures also cause various side reactions and degradation processes.

On the subject:

Thermal management is crucial for the performance and ageing behaviour of lithium-ion batteries. Established system solutions and innovative processes are presented. Good thermal management increases the range of the electric vehicle and extends the service life of the battery.

In this seminar you will learn about

  • the importance of temperature for performance and ageing behaviour
  • The reasons why thermal behaviour is so complex and so crucial
  • Solutions for thermal management systems and how they can be evaluated
  • the importance of cell design for thermal behaviour and thermal management
  • Tools that can form the basis for thermal management designs

For optimum operation in the vehicle, thermal management systems are therefore used to regulate the temperature of the battery. Efficient cooling concepts are in demand. Especially for critical operating scenarios such as fast charging, a powerful system is necessary to compensate for heat release. This tempering of the battery induces gradients and inhomogeneous temperature distributions within the cells or in the battery pack. The temperature distributions in turn influence the local electrical cell behaviour and can thus also potentially have a negative impact on the performance and ageing of battery systems. This creates a complex interplay between the electrical-thermal behaviour of the battery cells and the external temperature control application in the vehicle.

For the design of efficient thermal management systems, it is therefore not only crucial to have a sound understanding of battery behaviour, but also of the effect of different temperature control options on the temperature distribution in the battery system. With the help of this understanding, optimisations can be made to the thermal cell and pack design and an improvement in the performance and service life of the battery system can be achieved. The holistic consideration of the thermal behaviour of the battery system in the vehicle offers the possibility of releasing previously unused potential for reducing costs and increasing performance.

  • Summary and conclusion

Objective

In the seminar, participants learn the importance of temperature for the performance and ageing behaviour of lithium-ion batteries. Based on the thermal fundamentals, the application of thermal management is presented. By comparing established system solutions and innovative processes, an orientation and evaluation basis for different requirements is made possible. The seminar is completed by the presentation of basic tools for the design and optimisation of thermal management systems and thermal cell design.

Circle of participants

The seminar is aimed in particular at developers and managers from the fields of thermal management systems, cell and pack design, battery systems and battery ageing. The focus is on the automotive application of lithium-ion batteries as energy storage in electric vehicles.

However, the basic knowledge imparted is also transferable to the areas of stationary application as well as when used in Powertools. The target group is companies in the automotive industry, both OEMs and suppliers, as well as the power tool market.

In particular, SMEs as suppliers to the automotive industry can also gain an introduction to the thermal management design of lithium-ion battery systems through the contents taught.
