Frequently Asked Questions

What makes these EV terminals more sustainable than standard ones?

Our terminals are manufactured using 95.7% recycled copper tracked via blockchain and produced with a zero-process-water manufacturing cycle, significantly reducing the environmental footprint.

How does the liquid cooling integration work?

The terminals feature laser-sintered microchannels (200μm) compatible with glycol/water mixtures, allowing for 4.2kW of heat dissipation during high-speed charging.

Are these terminals reliable in extreme cold weather?

Yes, they are TÜV SÜD certified for extreme climates down to -60°C. The nanocrystalline grain structure prevents material embrittlement that typically occurs in cryogenic conditions.

What safety measures are in place for battery fire prevention?

The TFS-900 series includes intumescent seals that expand at 150°C to contain fire propagation, and they provide an 8.3-minute thermal runaway delay according to GB/T 40432 standards.

What is the expected lifespan in corrosive environments?

With our specialized graphene and plating coatings, the terminals offer a 25-year corrosion lifetime even in harsh marine environments, as validated by ISO 9227.

Can these terminals handle high-voltage DC systems?

Absolutely. They are designed with a 2000V DC isolation rating and can support 780A continuous current density, making them ideal for modern high-performance EV architectures.
