High-Voltage Reliability: Advanced Ceramic Seals for EV Battery Systems

As the automotive industry transitions to 800V+ platforms, the demand for superior electrical insulation and hermetic sealing has never been higher. At Shunda Electronic Ceramics, we provide specialized ceramic-to-metal sealing components designed to ensure the safety, longevity, and efficiency of EV power batteries and high-voltage distribution units (PDU).

Critical Components for Electric Mobility

Our technical ceramics are integrated into the heart of the EV powertrain:

Battery Terminal Insulators: High-purity Alumina seals that prevent electrical leakage and withstand internal battery pressure.

High-Voltage Relays & Contactors: Metallized ceramic envelopes for arc quenching and hermetic gas filling.

Sensor Housings: Protecting thermal and pressure sensors in the battery management system (BMS) from corrosive electrolytes.

Cooling System Isolators: Ceramic components that maintain dielectric integrity in liquid cooling circuits.

Technical Advantages in EV Environments

Metallization & Joining Expertise

For power battery applications, we offer advanced Mo-Mn (Molybdenum-Manganese) metallization followed by Nickel or Gold plating. This ensures:

Vacuum-Tight Seals: Leak rate less than $1 \times 10^{-9}$ mbar·l/s.

Superior Solderability: Compatible with laser welding and braze-on assembly lines.

Mechanical Strength: Robust joints that survive the vehicle’s 15-year service life.

Quality Compliance for Automotive

We understand the rigor of automotive supply chains. Our manufacturing processes are aligned with:

RoHS & REACH: Environmentally friendly materials.

PPAP Support: Production Part Approval Process documentation for Tier 1 audits.
