from chemistry to pack
Battery engineering draws from more disciplines than almost any other field in engineering. A complete battery system requires electrochemistry, thermal engineering, power electronics, embedded software, mechanical design, materials science, and systems integration — all working together, all constraining each other. Most engineers arriving in the field are already expert in one or two of these … Read more
AION Engineering INC In lithium-ion battery technology, optimizing cell performance and safety requires careful consideration of multiple parameters. Among these, the cut-off voltage is critical for balancing energy density and ensuring cell longevity and stability. While cathode chemistry often guides cell classification, variations in anode materials significantly impact the appropriate cut-off voltage setting. Influence of … Read more
When designing a battery pack / system it is important to think about and describe the safety concept. This needs to be considered in a systematic way and needs to cover: In each of these we need to look at the lifetime of the battery and the safety of it when being handled and used: … Read more
A look at the 2021 VW ID 4 82kWh battery pack. This battery pack architecture is used across a number of vehicles under the VW family umbrella and in a number of sizes. Hence, although this says the ID 4, this is the 82kWh battery design used by Skoda and Seat amongst others as this … Read more
If you’re assessing a pack supplier what do you need to think about? What questions should you ask? This list needs to have all of your requirements, be very clear on what you have to have and where you can change. Break it then into functions and components: You will see that the questions are … Read more
A good way of thinking about battery pack design is to look at components and functions. Even better if you have the luxury of having component owners and independent function owners. I think in terms of the five function headings: This post has been built based on the support and sponsorship from: Eatron Technologies, About:Energy, AVANT Future Mobility, Quarto … Read more
