MPP foam, a type of closed-cell foam derived from polypropylene
beads, offers a range of benefits that make it highly suitable for
insulation in NEV batteries. The unique properties of MPP foam,
including its thermal insulation, temperature stability, and fire
protection capabilities, contribute to the optimal performance and
safety of NEV battery systems.
With its exceptional thermal insulation properties and low thermal
conductivity, MPP foam effectively regulates and maintains stable
operating temperatures within NEV batteries. This is crucial for
preserving battery performance and preventing overheating, which
can lead to reduced efficiency and potential safety hazards. By
minimizing heat transfer, MPP foam ensures that the battery
operates within the desired temperature range, enhancing its
overall functionality and longevity.
One of the advantages of MPP foam is its versatility in density
options and customization. This flexibility allows manufacturers to
tailor the foam to meet the specific thermal protection
requirements of different NEV battery applications. By selecting
the appropriate density, NEV manufacturers can effectively optimize
temperature management, ensuring that the battery remains in an
ideal operating condition.
In addition to its thermal properties, MPP foam boasts excellent
fire protection capabilities. It is classified as UL94 V-0,
indicating its outstanding resistance to ignition and
non-propagation of flames once the ignition source is removed. This
fire-resistant characteristic makes MPP foam an ideal material for
NEV battery applications, as it helps prevent the spread of fire
and improves overall safety. In the unfortunate event of a fire,
MPP foam can contain the flames and aid in extinguishing them,
minimizing potential damage and reducing the risk of injury.
Overall, MPP foam offers a reliable solution for NEV battery
insulation, ensuring stable operating temperatures and providing
fire protection. Its thermal insulation properties, temperature
stability, and fire-resistant nature contribute to the efficient
and safe performance of NEV batteries. By incorporating MPP foam
into battery systems, NEV manufacturers can enhance the reliability
and safety of their vehicles, promoting the advancement of electric
mobility while prioritizing customer satisfaction and peace of
mind.
Thermal management is the term used to describe the ability to
control the temperature of a battery array. Batteries tend to heat
quickly when they are running at full capacity or during fast
charging. The main objective of battery pack thermal management is
to reduce uneven temperature distribution, or, put another way, to
maintain the temperature within the battery pack in a narrow range
(usually between 3° C to 4° C in ambient conditions that range from
-35° C to 50° C).
There are two different options in dealing with the heat generated
from the inside of a battery pack. One is to evacuate the heat,
which can be complex because it involves a cooling system
incorporating a cooling plate and cooling fluids (circulating a
glycol-based fluid through the cooling plate). The second option is
to insulate each battery component from each others using a thermal
material, usually an elastomeric foam with intrinsic heat
resistance properties.
