Breaking Down Electric Vehicle Batteries: From Cells to Modules to Packs!

Hello everybody, welcome to Monroe Live! My name is Tom Pre, and I’m the director of electrification for Monroe. If you don’t know who we are, we are a lean design consultancy specializing in new product development, with a focus on EV products, costing benchmarking, and tear downs. Today, we’re going to talk about batteries and their configurations as they relate to electric vehicle applications.

Behind me, I have a table full of different types of batteries, including cylindrical, pouch, and prismatic cells. Each type of battery has its unique features and designs, such as tabbed vs. tabless designs, cooling systems, and thermal management strategies.

We discussed the importance of understanding Ohm’s law in vehicle electrification, as it is critical for safety and understanding how the systems work. We also delved into the different types of battery modules, their configurations, and how they affect the overall performance of the battery pack.

Furthermore, we explored the concept of battery management systems (BMS) and their role in monitoring cell voltages, temperatures, and balancing functions. We also touched on the importance of cooling systems in battery packs, including bottom cooling, thermal interface materials, and the use of foam for expansion and contraction management.

Additionally, we discussed the calculation of energy content in battery packs, the difference between power and energy, and how packs are rated in terms of kilowatt hours. We also highlighted the dynamic capabilities of certain battery packs, such as the ability to change voltage configurations for fast charging.

Overall, understanding the intricate details of battery technology is crucial for the advancement of electric vehicles and sustainable transportation. If you have any further questions or topics you’d like us to explore, please feel free to leave a comment. Thank you for joining us today, and we look forward to your continued engagement in the world of electrification.
