Optimizing Battery System Module Assembly with Structural Adhesives
Electric vehicles (EVs) are charging ahead and transforming the automotive industry. The lithium-ion battery packs used to power EVs now not only match the strength and reliability of internal combustion engines (ICE), but are expected to exceed ICE performance. Because of these demands, EV batteries, which are the driver of the EV propulsion system, present a variety of challenges:
- Overall weight concerns
- Joining dissimilar substrates
- Noise and vibration concerns
- Protecting battery components from the environment
- Thermal management
With global automakers making battery electric vehicles (BEV) a top priority, the key to accelerating the lagging consumer adoption rate is addressing end consumer demands such as longer battery ranges, lower EV prices and quieter interior cabins.
By applying advanced adhesive technologies, car manufacturers will be able to reduce investment and operating cost, improve battery life and long-term performance, protect critical electronics and enable lightweighting, thereby meeting consumer demands. Indeed, chemistry solutions help overcome key challenges through bonding, sealing, coating and thermal management at the individual cell level all the way through the battery pack, continuing to the power conversion systems and control units. For battery system modules in specific, adhesives play an integral role in the construction and ensuring durability. This is because they provide significantly higher resistance to fatigue than riveted or welded assemblies while at the same time enabling the use of down-gauged and lightweight substrates.
Henkel offers a variety of adhesives that provide greater and more consistent connectivity throughout the battery ecosystem while protecting components from the harsh conditions in which EV batteries operate, including noise and vibration, extreme external temperatures and the particles and contaminants that can infiltrate the battery pack during normal driving conditions. To learn more, join us for the upcoming webinar: Advancing Battery System Module Assembly with Structural Adhesives on Thursday, Feb. 21, 2019 at 2:00 p.m. EST. In this webinar we will take an in-depth look into cell, cooling plate, and cover plate assembly adhesives, to address the challenges introduced above by examining thermal properties, strength vs. product usage and optimizing joint design
