The price differences of 120kW DC charging station enclosures mainly manifest in the following aspects:

Material:

- Metal materials: Stainless steel has strong corrosion resistance, while aluminum alloy is lightweight and has good heat dissipation. Both have high strength and can adapt to harsh environments, but they come with higher costs and prices. For example, a 120kW DC charging station with a stainless steel enclosure will be more expensive due to its corrosion resistance and quality.

- Plastic materials: Common plastics like polycarbonate and ABS resin are cost-effective, lightweight, and have good insulation. However, they have lower strength and heat dissipation compared to metals, making them suitable for cost-sensitive products at relatively lower prices.

- Composite materials: Materials such as fiberglass-reinforced plastic and carbon fiber composites offer excellent weather resistance, insulation, and mechanical properties. However, their complex production processes and higher costs result in higher prices.

Protection Rating:

Higher protection ratings like IP54 or IP65 require additional sealing, waterproofing, and dustproofing measures in design and manufacturing to ensure reliable operation in harsh environments. These measures increase production costs, leading to higher prices. For instance, a 120kW DC charging station intended for outdoor use with an IP65 rating will have a more expensive enclosure than one with a standard rating.

Process and Brand:

- Process: Enclosures made with high-precision molds and fine surface treatments are aesthetically pleasing and reliable in quality. However, their lower production efficiency and higher costs result in higher prices. Designs that prioritize scalability, with more interfaces and slots for future upgrades, also contribute to higher prices.

- Brand: Well-known brands invest heavily in R&D, production management, and quality control, ensuring product consistency and stability. They also offer reliable after-sales service, which may lead to brand premium and higher prices.
