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.

In this seminar you will learn about all technical aspects of battery management systems (BMS). Operation management strategies for the individual battery technologies are presented. The following topics will be covered:

  • Concepts for battery management systems in the automotive sector (lithium ion battery)
  • Hardware implementation of subsystems such as cell monitoring units, module and pack management units, balancing system
  • Functionalities and status determination (SOC, SOH, SOF, RUL, SOS) of the battery
  • Internal and external battery communication
  • Optimised charging and operational management strategies
  • Intelligent thermal management
  • National and international standardisation

On the topic

Every battery system (accumulator) requires a battery management system (BMS). The aim is to make optimum use of the battery 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):

  • Ladezustand (State of Charge, SOC)
  • State of Ageing (SOH)
  • Restlebensdauer (Remaining Useful Life, RUL)
  • State of Safety (SOS)

These states are determined using sophisticated algorithms that are either model-based or data-based. An operating strategy is derived from the measurement data determined by modules subordinate to the BMS and the states determined and predicted in the BMS. It is implemented by controlling the charging management, the thermal management, the inverters and the balancing system of the battery storage.

But even the design of the system, from the hardware concept of the housing to the contacting and the arrangement of the cells, influences the final performance of the overall system. Overall, the building blocks such as condition determination, measurement technology, the wiring concept, the balancing system, thermal management and the fundamental concept form the basis of a functioning battery management system.

Agenda

Online seminar, 09:00 to 16:30

  • Basics and terminology of batteries incl. Ageing and characterisation
  • System concepts and hardware implementation including balancing and therm. Management
  • Condition determination (SOC, SOH, SOF, measurements and model-based)

Objective

The aim of the seminar is to teach the basics of a battery management system at software and hardware level and additionally to address current trends in research. By participating in the seminar, they are able to take part in technical discussions on the topic of battery management systems.

Circle of participants

The event is aimed at everyone involved in the topic of battery management systems. Special focus is placed on the automotive sector.
