Product Overview

At Zhenshi Composite Materials, we believe that the foundation of safety, stability, and performance in any advanced energy storage system lies in reliable protection.

Our PCM Battery Cover represents the next generation of battery protection solutions — designed with high strength, flame retardancy, excellent insulation, and dimensional stability as its core principles.

Developed through advanced polymer composite molding and high-temperature curing technology, the PCM Battery Cover offers superior mechanical endurance, thermal management, and fire resistance.

It’s specifically engineered to meet the demanding requirements of new energy vehicles (NEVs), energy storage systems (ESS), industrial power batteries, and intelligent equipment housings — where safety, lightweight design, and long service life are critical.

Product Functions and Uses

The PCM Composite Base Plate serves as the load-bearing and protective foundation of a battery pack system, integrating mechanical support, electrical insulation, and thermal management functions in one lightweight, high-performance component.

Its primary role is to secure and protect battery cells, maintain structural rigidity, and resist deformation under vibration, impact, or thermal cycling. The composite design not only ensures long-term stability of the battery pack structure but also provides excellent dielectric properties that eliminate the risk of electrical leakage or short circuits.

Additionally, the PCM base plate offers fire-retardant and heat-barrier performance, effectively preventing thermal propagation in case of cell malfunction — a vital safety feature for lithium-ion and solid-state battery systems. In applications such as electric vehicles, energy storage stations, and backup power modules, the PCM base plate enhances both mechanical protection and system safety, ensuring reliability throughout the battery’s operational lifespan.

Product Features

Each PCM Composite Base Plate combines Zhenshi’s advanced composite formulation with precision molding and structural reinforcement. The result is a product that excels in both function and reliability:

High Strength and Stiffness: The PCM base plate features mechanical strength and rigidity far exceeding traditional metal or plastic bases. It maintains structural stability under heavy compression, vibration, and mechanical load, ensuring long-term durability of the entire battery assembly.

Fire Retardancy and Flame Resistance: Formulated with UL94 V-0 grade resin and high-temperature fiber reinforcement, the base plate effectively blocks flame spread and resists ignition even under severe thermal conditions, providing critical protection against battery thermal runaway.

Electrical Insulation: The material exhibits excellent dielectric strength and volume resistivity (>10⁹ Ω·cm), ensuring absolute electrical isolation between battery cells and metal enclosures. This helps prevent short circuits and enhances system safety.

Heat Resistance and Dimensional Stability: The PCM composite maintains structural accuracy even above 200°C, with a low coefficient of thermal expansion that minimizes deformation during long-term temperature fluctuations.

Lightweight Design: Compared with metal base plates, the PCM composite structure reduces overall system weight by 40–60%, contributing to greater energy efficiency in vehicles and portable energy systems.

Corrosion and Chemical Resistance: The base plate resists corrosion from electrolytes, salts, oils, and industrial cleaners, maintaining mechanical integrity in harsh environmental conditions.

Customization Flexibility: Available in flat, ribbed, or hollow-core configurations, the PCM base plate can be customized to specific design requirements for various battery module sizes and load conditions.

This unique combination of strength, insulation, and flame retardancy makes the PCM Composite Base Plate the trusted choice for modern high-performance energy systems.

Product Instructions

For optimal performance and reliability, proper handling and installation of the PCM Composite Base Plate are essential:

Storage: Store horizontally in a dry and clean environment. Avoid prolonged direct sunlight or moisture exposure before installation.

Machining: The base plate can be cut, drilled, or milled using standard composite tools (diamond or carbide). Maintain clean, low-vibration operations for best edge quality.

Assembly: It can be assembled using mechanical fasteners, structural adhesives, or hybrid joining methods. Ensure surfaces are free from oil and dust for proper bonding.

Thermal Management Integration: PCM materials are compatible with various thermal interface pads and insulation layers. Apply heat-conductive materials only where specified by the system design.

Maintenance: The base plate requires minimal maintenance. Periodic visual inspection for surface cracks or impact damage is sufficient. Clean with mild, non-corrosive agents.

By following these guidelines, users can maximize mechanical integrity, electrical insulation, and fire safety performance throughout the product lifecycle.
