Meaning
Mechanical structural frameworks hold and position discrete battery modules within an electric vehicle pack assembly. A battery module carrier secures multiple prismatic or pouch module blocks against shock and vibration while providing mounting locations for cooling plates and high-voltage interconnects. Fabrication typically uses extruded aluminum alloys or stamped high-strength steel to balance structural rigidity against total vehicle mass.
The carrier defines the physical boundary of the module tier inside the pack architecture and isolates structural loads from sensitive electrochemical cells during vehicle motion.
Mechanical Load
Dynamic acceleration and chassis twisting transfer forces into the enclosure during transit. Structural analysis of a battery module carrier measures deflection under crash loads and resonant frequencies to prevent fatigue failure of electrical connections. Fastener torque specs and structural adhesive bonds lock modules into position.
Shear stresses transfer into primary vehicle crossmembers.
Interface Integration
Thermal interface materials sit between module bottom plates and the carrier floor. The design of a battery module carrier incorporates pathways for coolant lines and low-voltage wiring harnesses. Dimensional tolerances control air gaps that would impair heat transfer to liquid cooling channels.
Production Sourcing
Stamping and extrusion tolerances drive manufacturing yield during pack assembly. Automotive procurement contracts for a battery module carrier evaluate dimensional repeatability across automated robotic welding cells. Component cost tracks raw material index prices for aluminum or steel alloys.
Quality audits verify weld penetration and anti-corrosion coating thickness.
