Guide EV tech explained: Why do EVs restrict the amount of battery
For example, a 125 Ah battery limited to 80% DoD is equivalent to a 100 Ah battery drained to 100% DoD, but at, say, 250 A, the 125 Ah pack is operating at 2 C compared to 2.5 C for the 100 Ah pack. Since the internal resistance of any type of battery tends to go down as its capacity goes up, a larger-capacity pack will waste less energy as heat at the same

6 Frequently Asked Questions about “Why can t the battery pack be filled with glue ”
Why do batteries need adhesives & sealants?
The adhesives need to allow the manufacturing as well as the structural and crash-durable joining of the battery enclosure. Adhesives and sealants are used to seal the battery from external environments and protect the cells and electronic parts inside the battery.
What is a battery adhesive?
Courtesy of Dupont. Some adhesives for battery assembly serve a multifunctional role, providing structural joining, thermal management, and support for dielectric isolation. Adhesives in this class offer thermal management and medium strength that supports the stiffness and mechanical performance of the battery pack.
Why should you use a crash-durable adhesive for a battery enclosure?
The crash-durable adhesives with a high modulus and high strength allow the construction of battery enclosures with an excellent structural stability and stiffness, so that the battery is also protected in case of a crash. An additional advantage is that the adhesive is not only bonding the substrates together but is also sealing the enclosure.
What makes a good battery adhesive?
On top of the thermal conductivity the adhesive further needs to show a good structural strength paired with a high elongation at break to maintain the mechanical structure over the lifetime of a battery also under load (e.g. vibration).
Why do EV batteries need adhesives?
An essential contribution of adhesives to EV battery design is that they allow for greater simplicity. For example, adhesives help reduce or eliminate mechanical fasteners, reducing battery complexity. Some formulations eliminate the need for primer, reducing the materials needed in production and VOCs associated with primer use.
How long do battery pack sealants last?
For vehicle longevity, OEMs need sealants for battery pack assembly that are both durable and serviceable. Today's sealants are reliable for the life of a vehicle—typically 15 years. The most advanced formulations are designed for serviceability by allowing seals that can be easily cut through to gain access and re-sealed after repair.
