3M™ Battery Enhancement Material, BEM 1807S, 1.52 m x 50 m

Greater range. Faster charging times. Extended xEV battery life.
Managing temperature is a critical consideration for automotive OEMs as they strive to increase driving range and optimize EV performance. Heating a battery in cold environments can require a large amount of power — much more than is required to keep it cool. Yet excessive temperatures can permanently impair the battery’s storage capacity and shorten its life.

Our 3M™ Battery Enhancement Material 1807S (PDF, 169.00 Kb) is an excellent solution. Our testing has shown that using this material to help manage ambient temperatures can prevent outside temperatures from heating the battery by as much as 33%. It can also help warm the battery as much as 20% faster in colder temperatures. This results in a reduction in power draw, meaning less battery power is required to keep the battery operating at its optimal temperature. The material can also add from 10% to 20% range depending on battery design, environmental and interior vehicle temperatures and consumer driving habits.

Properties of 3M Battery Enhancement Material
Thin and much lighter (less than 300 gsm basis weight) than most current battery thermal management solutions, 3M BEM ideal for cavity filling and for adding insulation to areas where using thermal management materials wasn’t possible before. It features an advanced fiber technology that combines low thermal conductivity with excellent compressibility and recovery properties. It performs under extreme temperatures (tested at -40°C for 24 hours; 150°C for 168 hours; and 120°C for 500 hours.) It also delivers UL 94 V-0 flame resistance.

3M BEM is a stable roll good that can be converted into shapes and configurations for design flexibility and installation efficiency. It is available slit, laminated, die-cut and edge-sealed to individual customer specifications.

Recommended Applications:

• Gaps between xEV battery pack and pack lid
• Bottom, top or wrapped around the battery pack within the battery case
• Commonly used under cooling plates
• Various types of xEV battery pack constructions

Why 3M Battery Enhancement Material?
xEVs can lose overall range when operated at cold and hot environmental temperatures, without even using the HVAC system. Managing this ambient temperature is crucial to keep xEV batteries operating within optimal temperature ranges and optimize performance and battery life.
