Energy Storage Pack Design for Safety and Flexibility: Techniques to Tackle Variant Cell Technologies – A Common Cabin Platform
Abstract
This work aims to address variations in cell technology in the energy storage domain, such that the end application does not require re-planning for safety, and provides flexibility in a common cabin platform. Designing a battery pack involves choosing high-quality lithium chemistry suitable for electric vehicle (EV) or electric power storage systems (EPSS) applications. Common options include lithium iron phosphate (LiFePO4) for its stability and safety, or NMC (nickel manganese cobalt oxide) for higher energy density. The factors that mainly impact battery pack design are cell selection, cell balancing and thermal management, BMS functionality for overall protection, custom design for space and safety, particularly suiting the retrofit vehicles, cell monitoring and data logging. Implement continuous monitoring and data logging capabilities using the Internet of Things to track the battery’s health, which can help with early detection of potential issues. Ensure that the battery pack design complies with industry and safety standards specific to EV OR EPSSs, such as ISO 26262 and UN ECE R100, with rigorous testing and certification, and also adhering to environmental regulations and guidelines that include recycling or disposal, providing a user manual for comprehensive understanding. This effort includes collaborating with experienced engineers and experts in battery technology, and EPSS design is essential to get real-world usage feedback to create a safe and efficient lithium-ion battery pack that can meet the rigorous demands of space and safety requirements. Additionally, staying up-to-date with the latest advancements in battery technology and safety standards is crucial for ongoing improvements in design.
