New Energy Power truck parts Power battery pad B 2120214-TE8A0

Built as the core buffer component between the battery pack and chassis, this pad delivers exceptional shock absorption performance using high-density EPDM (ethylene propylene diene monomer) rubber with a shore hardness of 50±5. It can compress 30% under 500N load and quickly rebound to original shape, effectively absorbing road vibrations (5-2000Hz) generated during truck operation—reducing battery pack vibration amplitude by 60% compared to standard rubber pads. The pad’s multi-cell internal structure disperses impact energy evenly: in 10J impact tests (equivalent to a 50kg object falling 2cm), it prevents direct force transmission to the battery casing, avoiding damage to internal cells or BMS (Battery Management System) modules. This buffering effect extends battery service life by 25% in rough-road operations

Designed to withstand the harsh under-chassis environment of commercial NEVs, the pad exhibits exceptional resistance to corrosion and aging. The EPDM rubber material is impervious to road salt, battery electrolyte (lithium hexafluorophosphate), diesel fuel, and cleaning agents—with no volume change (≤2%) after 72-hour immersion in alkaline solution. It resists UV aging, maintaining elasticity after 2000-hour QUV testing (ASTM G154) without cracking or hardening. The pad operates stably in extreme temperatures from -40℃ (northeast China winters) to 85℃ (desert regions), passing 500 thermal cycles (-30℃ to 100℃) with no performance degradation. Additionally, it resists mold growth (GB/T 24346-2009 Class 0) in humid environments, ensuring long-term reliability for over 8 years/400,000km

Engineered to maintain battery pack stability during dynamic truck operation, the pad integrates precision positioning and anti-slip features. The 4 integrated positioning bosses (diameter 30mm, height 10mm) fit into the battery pack’s bottom recesses, ensuring lateral positioning accuracy within ±1mm and preventing battery shifting during sharp turns or emergency braking. The upper surface features a diamond-patterned anti-slip texture (groove depth 2mm) that increases friction coefficient to 0.85 between the pad and battery casing, eliminating relative sliding even under 0.5g lateral acceleration. The pre-drilled mounting holes are chamfered (1mm) to guide bolt installation, avoiding cross-threading, while the pad’s uniform thickness (tolerance ±0.5mm) ensures even force distribution across the battery pack’s bottom surface

Optimized for efficient NEV fleet maintenance, the pad features a user-friendly design and environmental safety attributes. It is lightweight (3.2kg) and flexible, simplifying handling and installation—two technicians can position and secure it in 20 minutes using the included M10×35 galvanized bolts (grade 8.8) and lock washers (torque requirement: 35-40N·m). No specialized tools are needed, as the pad’s flexibility allows it to adapt to minor chassis deviations. The EPDM material is RoHS-compliant, containing no heavy metals (lead, mercury) or harmful plasticizers, ensuring environmental safety during production and disposal. The pad’s maintenance-free design (no cleaning or replacement of auxiliary components) and low cost make it an economical choice for fleet operators, while its high durability reduces the frequency of battery system overhauls
