This course on the fundamentals of batteries and battery systems is designed for engineers and technicians who work in the field of battery development or who use batteries as part of their systems and want to gain a better understanding of the design and control of battery systems. There are a variety of areas where battery systems are used, for example, engineers working in e-mobility or renewable energy will benefit from this specific expertise. As the course provides a general introduction, it is suitable for all types of battery systems.
What are Battery Systems?
A battery system typically consists of one or more battery cells that chemically store electrical energy. These cells are usually housed in an enclosure and can be connected in series or parallel to provide the desired voltage and capacity.
A battery management system (BMS) monitors the charging and discharging of the batteries to ensure that they operate efficiently and safely. It regulates the flow of energy, protects the batteries from overcharging and deep discharging, monitors temperature development and ensures optimal use of the battery capacity.
Why are Battery Systems Needed?
Battery systems are needed for various applications. They are used in electric cars, hybrid vehicles and electric two-wheelers to store electrical energy for propulsion. This also applies to many power tools such as drills, lawn mowers, vacuum cleaners, and other household appliances. Solar power systems require battery systems to store excess solar energy and retrieve it when needed. Battery systems are needed as backup power sources to provide uninterruptible power supply for critical infrastructure e.g. in hospitals, data centers, and telecommunications facilities. Large battery storage systems are used in power grids to balance peak loads, integrate renewable energy, improve grid stability, and optimize power supply efficiency.
How are Battery Systems Related to Embedded Systems?
To control and manage battery systems a battery management system is needed. A BMS is a customized embedded system specifically designed to meet the needs of battery monitoring, control and diagnostics.
A BMS includes both hardware and software components that are tightly coupled and work together to ensure the safe and efficient operation of the battery.
What can you Learn about Battery Systems in the Embedded Academy E-Learning?
In the first e-learning, we get to know the battery cell itself in more detail. We learn what materials it can be made of and how it works when it is charged and discharged. At the end, we will look at the parameters that influence the battery’s performance.
The second e-learning is about the battery system of an electric vehicle, different cell types and battery safety. We take a look at the 48V battery as an example.
