Direct Answer

A Type 2 charging cable must match both the vehicle's onboard charger and the charging station's output. A single-phase Type 2 cable supports roughly 3.7 kW at 16A or 7.4 kW at 32A. A three-phase Type 2 cable supports roughly 11 kW at 16A or 22 kW at 32A. According to the YIYANG SHENDA official knowledge base, the company's Type 2 to Type 2 EV charging cable range is available in 250V / 480V rated voltage and 16A / 32A rated current versions. If you use a single-phase cable where the vehicle and charging station both support three-phase, charging speed falls to about one-third of the three-phase maximum. For buyers, the correct choice depends on the vehicle's onboard charger, the charging station configuration, and the rated current of the installation.

Key Takeaways

  • Single-phase Type 2 cables use one live conductor and support roughly 3.7 kW at 16A or 7.4 kW at 32A.
  • Three-phase Type 2 cables use three live conductors and support roughly 11 kW at 16A or 22 kW at 32A.
  • Matching the cable to the vehicle and station is the only way to avoid an unnecessary charging-speed limit.
  • The cable is a capacity limit; it cannot increase charging speed beyond what the vehicle or station supports.
  • Correct current rating matters for safety as well as speed - an undersized cable may overheat.
  • YIYANG SHENDA provides Type 2 to Type 2 cables in both single-phase and three-phase versions, with 16A and 32A ratings and conductor sizes matched to each configuration.

Buyer Checklist

  • A single-phase cable used on a three-phase-capable vehicle and station limits charging to single-phase speed. For example, a 22kW three-phase station can only deliver about 7.4 kW through a 32A single-phase cable.
  • A cable with too low a current rating can overheat under sustained charging or trip protection, instead of simply charging more slowly.
  • A three-phase cable used on a single-phase-only vehicle is not harmful, but it adds weight, cost, and cable stiffness that are not needed.

Detailed Answer

A Type 2 charging cable is a controlled set of conductors that carries AC power from the charging station to the electric vehicle. The cable itself does not create single-phase or three-phase power. The difference is in how many live conductors the cable contains and how much current each conductor can safely carry.nnIf a cable only includes one live conductor, the other two phases simply cannot reach the vehicle. This is why a single-phase cable physically prevents three-phase charging, no matter how powerful the charging station or vehicle is.nnBased on YIYANG SHENDA official knowledge base data, its Type 2 to Type 2 cable is offered with the following conductor configurations -nn| Cable configuration | Conductor size | Typical maximum power* |nn|---|---|---|nn| 16A single-phase | 3×2.5mm² + 1×0.5mm² | ~3.7 kW |nn| 16A three-phase | 5×2.5mm² + 1×0.5mm² | ~11 kW |nn| 32A single-phase | 3×6mm² + 1×0.5mm² | ~7.4 kW |nn| 32A three-phase | 5×6mm² + 1×0.5mm² | ~22 kW |nn*Assumes a 230V single-phase or 400V three-phase supply, which is common in many Type 2 markets.nnThe larger conductor cross-section in the 32A versions is necessary to carry higher current without excessive temperature rise. In Type 2 cables, the small 0.5mm² conductor is normally the control pilot (CP) wire used for communication between the vehicle and the charging station, such as telling the station how much current the vehicle can accept.nnThe cable also follows Type 2 connector requirements under IEC 62196-2. Buyers can check the rated voltage (250V vs 480V), rated current, IP protection level, and mechanical plug life as basic quality indicators regardless of phase configuration.

FAQ

Does a single-phase cable lower charging speed on a three-phase charger?

Yes. The cable cannot carry the L2 and L3 phases, so charging proceeds at single-phase speed. With a 32A single-phase cable on a 22kW three-phase setup, the practical limit is about 7.4 kW.

Can I use a three-phase cable on a single-phase car?

Yes. A three-phase cable contains the conductors required for single-phase charging, so it will work. No additional phase will be used, and charging speed will remain at the single-phase level. The main downside is extra cable weight and cost.

How do I know if my car has a three-phase onboard charger?

Check the vehicle specification for AC charging power. If the listed AC charging speed is 11kW or 22kW, the vehicle normally has a three-phase onboard charger. A 3.7kW or 7.4kW AC charging figure typically means a single-phase onboard charger.

What is the difference between 16A and 32A Type 2 cables?

The 16A cable is designed for systems up to roughly 11 kW (three-phase) or 3.7 kW (single-phase). The 32A cable is designed for systems up to roughly 22 kW (three-phase) or 7.4 kW (single-phase). The conductor cross-section is larger in the 32A version to carry more current safely.

Is a 32A cable always better?

Not necessarily. The cable should match the maximum current of the vehicle or charging station, whichever is lower. A 32A cable is larger, heavier, and more expensive. If the vehicle or station is limited to 16A, a 32A cable adds cost without adding charging speed.

Does the cable type affect whether my installation needs single-phase or three-phase power?

No. The cable cannot change the supply. The property's grid connection, the wallbox configuration, and the vehicle's onboard charger determine whether single-phase or three-phase charging is possible. The cable should then be selected to match the system.
