The development of battery systems requires a detailed understanding of the requirements. Detailed requirements will help to avoid misunderstandings in development. The process of requirement analysis includes negotiation, documentation, and discovery. The process is aimed at defining the characteristics that the final product should have. The requirements are the determining factor in the development of a battery system. This is because they must be satisfied to be a success.
After defining the product requirements and defining its functionality, concept development begins. 21700 This process involves identifying and assessing customer needs and analyzing feasibility. This phase of the process also involves the development of a business plan. Once the concept is chosen, detailed battery engineering activities are carried out. This includes designing the module’s interior and exterior components.
The thermal management of a battery system is critical for the long-term efficiency of the system. Often, battery systems require additional energy to maintain their operating temperatures. Therefore, the system should be designed with thermal management in mind. Fraunhofer ISE’s thermal engineering specialists can help battery manufacturers to design and optimize their cooling systems. They also develop state-of-the-art thermal modeling techniques.
During the development process, a team of designers and engineers will work with the customer to identify the best way to create a battery system that meets their specific requirements. The process is interdisciplinary and agile. It involves the structural design, E/E architecture, thermal management, and modularisation. The team will also perform market analysis and provide project management.
Using different materials can optimize the battery’s energy density and service life. The main components of a battery cell are the anode, cathode, and separator. The electrodes are made of silicon or graphite and are applied in layers.
A battery system management system is a vital part of modern lithium-ion battery systems. These systems must be able to shut off in the event of an error. This is why functional safety is essential. Fraunhofer ISE can advise on the functional safety of a battery system and prepare a corresponding overall concept for certification.
Users vary significantly in their driving habits, influencing long-term energy usage and battery system efficiency. Creating models based on user-specific driving patterns can help design and develop battery systems. They can be used to predict various user behaviors, including the type of speed limit, road conditions, and more.
Using state-of-charge estimations in battery systems is crucial for the safety and performance of these devices. These measurements’ accuracy depends on the battery’s capacity and charging rate. The correct estimation of SOC prevents overcharging, which can result in battery death.
