6 FAQs about [New Energy Battery Chassis Protection]
Why is pack design important for solid-state batteries?
Pack design will be critical for future solid-state batteries Solid-state batteries are touted as the endgame for battery technology, boasting high energy density and improved safety. However, pack design will still be crucial to making them viable.
What is an EV battery enclosure?
(Novelis) EV battery enclosures are a hotbed of subsystem design, materials innovation, and vehicle integration. Whether you call them packs, boxes, or trays, the structures that envelop and protect EV battery cells and their supporting electrical and thermal-management hardware are among the industry’s top subsystem priorities.
Can NMC cells be used as a battery pack?
Of course, the same structure could be applied to NMC cells, leading to an even smaller battery pack, or one could increase the number of cells in the same space to increase vehicle range. The cell-to-pack approach has made the LFP pack much more viable as an option in terms of fitting the necessary battery capacity in a vehicle.
Are low-cost battery chemistries affecting EV range?
This has seen many turning to lower-cost battery chemistries like LFP (lithium iron phosphate). In fact, IDTechEx found that 33% of the global EV market used LFP cells in 2024. However, the trade-off comes in a loss in energy density (and hence vehicle range). So, what can be done at the pack level to balance these trade-offs?
Are EV batteries a 'battle for the box'?
The “battle for the box” has kicked off a new wave of creativity among engineers and materials scientists. Roughly 80% of current EVs have an aluminum battery enclosure, but engineers are quick to note that the field is wide open for alternatives, based on vehicle type, duty cycles, volumes, and cost.
What are thermoplastic EV battery trays?
Engineers’ interest in thermoplastic EV battery trays began with GM’s 1990 Impact concept car. The EV-1 production car that followed used a tray made of glass-filled polypropylene (PP). SABIC’s latest innovation aims directly at one of aluminum’s weaknesses — its very high thermal conductivity.
