There's a lot going on inside an EV battery pack, and things can get pretty hot!

Battery cells, electrical connections, and high-voltage components all generate heat during operation. Keeping that heat under control is a big part of making sure EV batteries perform safely and reliably.

That's where Essex Brownell comes in.

We supply thermal management materials that help move heat away from critical components, along with electrical insulation and thermal barriers that provide protection where it's needed most.

And with our custom converting capabilities, we can turn those materials into components designed to fit specific battery applications for our customers.

A lot goes into building an electric vehicle, aircraft, or EV charging station. And we're not just talking about the major components.

Behind every finished product are countless critical materials and components, from electrical insulation and adhesive tapes to custom die-cut parts and protective barriers. Sourcing, preparing, and organizing those materials takes time, and every additional step can impact production efficiency.

That's where Essex Brownell's kitting services make a difference.

We supply the materials, customize them to your specifications through our value-added capabilities, and then package the components together into assembly-line-ready kits.

That means fewer individual parts to manage, less time spent gathering materials, simplified inventory management, and a more streamlined assembly process. By reducing unnecessary handling and preparation, kitting can also help lower labor costs and improve overall production efficiency.

We're making it easier for our customers to focus on what they do best: building the products that move industries forward.

Flexible insulation plays an important role in automotive safety, performance, and reliability.

Insulating papers, films, tapes, and sleeving each serve a unique purpose in protecting critical electrical components. These materials help prevent electrical shorts, protect wiring from heat and abrasion, and maintain electrical isolation in demanding automotive environments.

As automotive technology continues to evolve, manufacturers need insulation materials that meet increasingly complex electrical and thermal requirements.

At Essex Brownell, we offer a broad portfolio of flexible insulation materials from trusted supplier partners, along with value-added capabilities like die cutting, laminating, kitting, and custom part forming to help meet specific application needs.

Electric vehicles rely on high-voltage electrical systems, powerful batteries, and advanced electronics to deliver the performance drivers expect. But behind these technologies is something that doesn't always get the attention it deserves: electrical insulation.

Here's why it matters:

1. Prevents Electrical Shorts
EVs contain tightly packed electrical components, making effective insulation essential. Materials like electrical tapes, films, and insulating papers separate conductive surfaces, helping prevent unintended electrical contact.

2. Helps Limit Heat Propagation
EV batteries generate heat during operation, and thermal runaway presents a serious safety concern. Specialized materials, including mica-based barriers and flame-resistant insulation, can help slow heat transfer and reduce the risk of thermal runaway spreading between cells.

3. Protects High-Voltage Systems
EV electrical systems operate at significantly higher voltages than traditional automotive systems. Insulating materials with appropriate dielectric strength help prevent electrical breakdown and isolate high-voltage components, including busbars, connectors, battery assemblies, and power electronics.

4. Supports Long-Term Reliability
EV components face continuous exposure to temperature fluctuations, vibration, electrical stress, and demanding operating conditions. Properly selected insulation materials help maintain electrical integrity, reduce premature degradation, and support consistent performance throughout a vehicle's service life.

At Essex Brownell, we supply a broad portfolio of electrical and thermal insulation materials from trusted industry-leading manufacturers. Combined with our value-added capabilities, including die cutting, laminating, and custom part forming, we help customers find solutions tailored to their specific EV applications.

You probably expect to find magnet wire in an EV motor. But that’s not the only place it’s working behind the scenes.

Magnet wire can also be found in onboard chargers and DC-DC converters, helping move, convert, and manage electrical power throughout the vehicle.

Swipe through for a closer look at three places magnet wire helps keep an EV moving, charging, and powered.
