Battery management systems for automotive applications

The means of transport of the future will be electric (electromobility). Electric vehicles with lithium-ion batteries are currently in vogue. The use of battery systems (batteries) is therefore becoming increasingly widespread, particularly in the automotive sector. Every battery system (accumulator) requires a battery management system (BMS), the aim of which is to optimise the use of the battery storage system in order to achieve the greatest possible range and a long service life. To achieve this goal, the BMS determines various states of the battery system (the battery cells), from the State of Charge (SOC) to the State of Health (SOH) to the Remaining Useful Life (RUL) or the State of Safety (SOS) of the battery.

Digital twins in battery cell production

The seminar deals with the use of digital twins over the product life cycle of a battery cell or battery system. The contents include today’s potentials, current solutions and future challenges.

Dealing with accident-damaged electric vehicles and defective batteries

Based on the structure of EVs and their components and systems, the main hazards and safety measures in case of accidents with electric cars are covered. This covers electrical safety, battery fires and chemical hazards as well as the basics of firefighting and deactivation of energy storage devices.

Green batteries through Computational Life Cycle Engineering

You will receive an overview of the state of research in the ecological assessment of traction batteries and battery electric vehicles over the life cycle. An introduction to the methodology and modelling of computational life cycle engineering as well as a consolidation of findings and discussion of paths for the further development of sustainable traction batteries (recycling) round off the agenda.

Thermal runaway and thermal propagation in lithium-ion batteries

The seminar will discuss the basics of thermal runaway and thermal propagation in lithium-ion batteries and present testing and simulation options. In addition, the standards and legal situation for thermal propagation is examined and aspects of functional safety in connection with thermal propagation are addressed (hazard and risk analysis according to ISO 26262:2019). Information on detection possibilities and the correct handling of lithium-ion batteries round off the seminar.

Check and test batteries correctly

Electric cars are vehicles without a combustion engine but with a large battery (traction battery) instead of a fuel tank. The seminar will first briefly and succinctly discuss the functioning and structure of the various electrochemical energy storage devices (rechargeable batteries) in order to be able to understand the requirements for testing. This includes in particular topics such as voltage (e.g. high voltage), performance, capacity, safety, designs and operating conditions.

Basic knowledge batteries

In this seminar you will acquire expertise in lithium-ion batteries in traction batteries. In addition to the materials used, the technology for production and the criteria for evaluation are discussed.

Ageing and post-mortem analyses of lithium-ion cells

In the first part, general aspects of battery ageing are discussed, followed by the methodology of post-mortem analyses based on current literature as well as examples from everyday laboratory work. Special attention is paid to which ageing mechanism can be detected with which method. In the second part, known ageing mechanisms are discussed. Finally, possibilities are shown how the service life of lithium-ion cells can be specifically extended. The seminar contents shown are based on the speaker’s own experience as well as on current literature.

Lithium Ion Batteries – Safe Handling in the Work Environment and Daily Practice

In this online seminar, practice-relevant and field-tested measures and procedures in the fields of logistics, use, testing, storage, service, occupational health and safety, occupational safety and repair in the field of lithium-ion batteries are presented and discussed. Implementation options and variants are presented or jointly developed. The topics presented and developed can then be implemented 1:1 in the participants’ own environment.

Tempering lithium-ion batteries correctly

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 (electric cars). 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.
