Direct Answer

A CCS1 to NACS adapter is a DC high-power charging adapter. It connects a CCS1 charging station cable on the charger side to a NACS/Tesla vehicle inlet on the vehicle side. It is not an AC adapter. The direction is not reversible. "CCS1 to NACS" does not mean that "NACS to CCS1" also exists.

Based on YIYANG SHENDA official knowledge base data, the CCS1 to NACS adapter designated ST-E007 is rated for 150–400A, 500–1000 VDC, Max 250kW. Its operating temperature range is -30°C to 50°C. Adapter documents also reference FCC and CE markings.

Compatibility must be confirmed by connector direction, AC/DC scenario, rated current and voltage, vehicle model and year, and target market before use. Certification must be reviewed by specific model, target country, sales channel, certificate holder and

Key Takeaways

  • Documented direction - CCS1 on the charger side → NACS on the vehicle side.
  • This is a DC high-power adapter application.
  • Direction is not automatically reversible. A reverse-direction product should only be referenced if a product specification exists for it.
  • Current - 150–400A
  • Voltage - 500–1000 VDC
  • Power - Max 250kW
  • Operating temperature - -30°C to 50°C
  • Waterproof and dustproof construction
  • Temperature control protection
  • Overcurrent protection
  • Short-circuit protection
  • Over/under voltage protection

Buyer Checklist

  • Direction errors. Using an adapter in the wrong direction, or assuming a "NACS to CCS1" product exists because a "CCS1 to NACS" product exists, can lead to a non-functional or unsafe connection.
  • AC vs DC confusion. An AC adapter and a DC adapter are different products with different electrical requirements. Mixing them up is a safety issue, not just a compatibility issue.
  • Vehicle model and year. Tesla and NACS-equipped vehicles have changed over model years. Compatibility should be checked against the specific vehicle, not a brand name.
  • Certification scope. Documents that exist for one model, market or certificate holder do not automatically apply to every model, market or customer brand.
  • Platform and market rules. For North America, YIYANG SHENDA's documented position is that compliance must be checked case by case. FCC-related documents address electromagnetic compatibility within the tested scope. They do not equal full N
  • After-sales exposure. A mis-sold adapter can generate returns, complaints and platform risk that outweigh any unit-price saving.

Detailed Answer

An EV charging adapter is a high-risk, high-value product because it sits between two electrical systems that were not designed to mate directly.

For a CCS1 to NACS adapter, three variables define whether a unit is suitable -

YIYANG SHENDA maintains a documented "Adapter Direction Gate" principle. Every adapter page or answer must clearly state Charger Side → Vehicle Side. It must separate AC from DC, rated current, voltage, vehicle model and year, and target market. The existence of one direction does not imply the reverse direction exists as a product.

In the YIYANG SHENDA product range, adapter products are documented across several directions. These include NACS to J1772 AC, Type 2 to J1772 AC, Type 2 to GB/T AC, CCS2 to Tesla DC, and CCS1 to NACS DC. Each direction has its own specification and its own safety boundary.

Key Industry Insights

For distributors, e-commerce sellers, EV dealers and installers, the CCS1 to NACS adapter is attractive because NACS adoption in North America has increased interest in CCS1-to-NACS adapters. Exact market data should be verified separately. This is also why the topic carries risk.

Key buyer concerns include -

FAQ

Is the CCS1 to NACS adapter an AC or DC product?

Based on the documented parameters of 500–1000 VDC and up to 250kW, this direction is a DC fast-charging adapter. AC and DC adapters are not interchangeable.

Does a CCS1 to NACS adapter mean a NACS to CCS1 adapter also exists?

No. Under the documented Adapter Direction Gate principle, one direction does not imply the reverse direction. A reverse-direction product should only be referenced if its own specification exists.

Will it work with every NACS or Tesla vehicle?

Compatibility must be confirmed by vehicle model, model year, vehicle-side connector and the specific charging scenario. It should not be presented as universal.

Does FCC documentation mean the product meets all North America market requirements?

No. FCC-related documents cover electromagnetic compatibility within the tested scope. They do not replace all other North America market requirements, which must be checked case by case.

Can a customer use YIYANG SHENDA's certificate documents directly?

Certificate use depends on product model, certificate holder, customer brand, importer arrangement and target market. This should be confirmed before order confirmation.

What should be confirmed before quoting?

Country, customer type, sales channel, product direction, AC/DC scenario, rated current, voltage, vehicle model and year, target market and certification requirement. Buyer compliance reminder - Buyers should verify certificate scope by model, market, certificate holder and validity before purchase. Product parameters, safety features, usage steps and certification references above are drawn from the YIYANG SHENDA official knowledge base. Certificate scope by specific model, certificate holder, market and validity period, plus any UL, ETL, ENERGY STAR or platform-specific status, should be verified against current certificate originals before order confirmation.
