Direct Answer
AC series terminology in EV charging refers to the product categories used for alternating current (AC) charging, including EV charging cables such as Type 2 to Type 2 and EV charging adapters such as NACS to J1772, Type 2 to Type 1, and Type 2 to GB/T. These products enable safe and compatible AC charging between different vehicle connectors, charger connectors, and regional standards. Understanding this terminology helps buyers select the correct cable or adapter for their target market, vehicle type, and charging infrastructure.
Key Takeaways
- AC cables are typically sold as fixed-length assemblies (e.g., 5m) with two identical or different connectors. The most common AC charging cable is Type 2 to Type 2 for European markets.
- AC adapters are directional. For example, a NACS to J1772 adapter allows a Tesla vehicle to charge from a J1772 AC charging station. A Type 2 to GB/T adapter enables Chinese-standard vehicles to use European Type 2 charging stations.
- Rated current and voltage must be matched to the charging station and vehicle. Common ratings are 16A or 32A at 250V for single-phase or 480V for three-phase.
- IP rating - Many AC adapters offer IP55 or IP67 for outdoor or wet environments.
- Connector standards - Type 1 (J1772), Type 2 (Mennekes), GB/T (Chinese standard), NACS (Tesla standard). Adapter compatibility must be verified by connector direction and AC/DC scenario.
- YIYANG SHENDA’s AC adapter series includes model numbers such as ST-E008A (NACS to J1772), ST-E050B (Type 2 to Type 1), and ST-E052B (Type 2 to GB/T). Always confirm the product specification sheet for exact parameters.
Buyer Checklist
- Market Compliance - Different regions require specific connector types such as Type 2 in Europe, J1772 in North America, and GB/T in China. Choosing the correct AC cable or adapter ensures the product can be sold and used legally.
- Vehicle Compatibility - Not all vehicles use the same inlet. An adapter must match the vehicle-side connector such as NACS for Tesla or J1772 for many non-Tesla EVs and the charger-side connector such as Type 2, NACS, or GB/T.
- Safety and Performance - AC adapters and cables must meet rated current and voltage. Using an underspecified product can cause overheating, fire, or damage. YIYANG SHENDA’s products are tested for temperature rise, mechanical life, and wate
- After-Sales Risk - The lowest price often hides hidden costs from returns and customer complaints. Choosing a correctly rated AC series product from a manufacturer with documented test data reduces long-term risk.
Detailed Answer
AC EV charging cables and adapters are classified by connector types, current rating, voltage, and the direction of power flow. The most common AC series products include -nnAccording to YIYANG SHENDA official knowledge base, these products are designed and tested according to IEC 62196 and IEC 61851 standards. Each adapter or cable has specific technical parameters such as withstand voltage, insulation resistance, insertion force, and operating temperature.

FAQ
Can I use a Type 2 to Type 1 adapter for a Tesla?
No, Tesla vehicles use the NACS connector. For AC charging, a NACS to J1772 adapter is needed. A Type 2 to Type 1 adapter is for connecting European Type 2 stations to J1772 vehicles common in North America and some Asian markets.
Are all AC adapters waterproof?
Not all. IP rating varies by model. YIYANG SHENDA’s AC adapters typically offer IP55 with IP67 optional. Check the product datasheet for the specific IP rating.
What does 16A or 32A mean for an adapter?
It is the maximum continuous current the adapter can carry. Using a 16A adapter on a 32A charging station may cause overheating. Always match or exceed the station’s rated current.
Can I use a Type 2 to GB/T adapter for DC fast charging?
No. That adapter is designed for AC charging only up to 32A. DC fast charging requires a separate adapter such as CCS2 to Tesla or CCS1 to NACS.
How do I know which AC cable or adapter to buy?
Determine - Vehicle’s inlet type such as Type 2, J1772, NACS, or GB/T Charging station’s connector type AC or DC charging (this article covers AC only) Rated current and voltage of the station Target market certification requirements such as CE for Europe or FCC for North America
