The accelerating growth
of electric-powered
vehicles puts pressure
on vehicle and battery
makers to deliver more
robust, compact and
powerful battery modules.
Battery module designs
vary widely by
manufacturer and specific
end application, and with
advanced battery modules for
EVs and public transportation
containing thousands of individual
cells, it increases complexity of
the system.
To meet growing industry
demands, battery design engineers
are seeking out more robust and
adaptable interconnect technologies
for the increasing variety of battery
module sizes and designs.
Cell-PLX technology, created by
Interplex, addresses this need with
customized battery interconnect
systems tailor-made for specific
application requirements. It is
suitable for use with cylindrical,
prismatic or pouch battery cells,
it supports various current densities
and cell array configurations, with
robust packaging formats to uphold
battery module durability in
high-vibration environments.
Interplex’s design expertise and
vertically integrated in-house
production can help businesses
accelerate their battery interconnect
system’s time-to-market. Cell-PLX
provides maximum configurability
for di erent form factors, sizes and
performance requirements, with a
wide range of material options and
plating finishes.
Cell-PLX’s high-precision current
collectors maintain the tight
tolerances needed for reliable and
long-lasting performance.
Thicknesses can be customized to
match current density requirements.
Positive and negative cell
connection terminals can be formed
down to cell level for laser welding
or wire bonding to the battery cells.
In applications that require
positive and negative terminals to be
on the same side of the battery cell,
Cell-PLX can be configured with
two current collectors separated by
a dielectric layer, or
a single thicker current collector.
Using advanced high-speed
manufacturing processes, the
terminals can be thinner than the
current collector itself. This assures
ease of welding to the battery cells
while maintaining strength and
structural integrity across the entire
current collector. Customized
designs also enable optimal
positioning of the terminals for
mating with the cells.
This, combined with options for
configurable and secure battery
cell holders, improves connection
quality and robustness. Cell holders
also have the ability to incorporate
the bottom dielectric layer, which
can then be attached to adjacent
layers by heat staking instead of
pressure-sensitive and thermal
activated adhesives.
Cell-PLX technology also allows
integration of custom-designed
overmolded lead frames to connect
Battery Management System (BMS)
control boards to the current
collectors. Various connection
options between battery modules are
possible, such as nut/bolt, pin/socket
and other custom configurations.
Other interconnect design
options allow for passive and active
component placement for safety
and cell monitoring such as fuses,
thermistors, most positive and
negative interconnects, cell holder
designs, signal interconnects or
harnesses/circuits connecting to
the control board.
To cater to the growing range of
advanced battery applications, the
underlying interconnect
implementation technologies must
deliver both durability and
adaptability for application-specific
requirements. The customizability
of Cell-PLX battery interconnect
systems enables this technology
to be applied to an extensive range
of applications, such as aerospace
(electrification of civil aviation);
automotive (EVs); commercial
transportation; maritime vessels;
personal mobility; energy (wind
and solar energy storage).
Robust, customizable battery interconnect systems
