Direct Answer

A 7kW wallbox EV charger is a wall-mounted AC charging station typically rated at 7kW, delivered through a single-phase 230V supply at 32A. It is one of the most widely used AC charging capacities for homes, apartments, and light commercial installations in markets that operate on single-phase electricity.

In short - 7kW wallbox = Mode 3 AC charging station, single-phase 230V, 32A, suitable for overnight and everyday charging where a three-phase supply is not available or not required.

Key Takeaways

  • 7kW AC wallbox = single-phase 230V, 32A, Mode 3 charging station.
  • Standard structural references - IEC 61851-1 and IEC 62196 series for connector compatibility.
  • Protection functions such as overvoltage, undervoltage, overcurrent, leakage, overtemperature, lightning, grounding, and relay sticking protection.
  • Leakage protection options including Type A and Type A + DC 6mA.
  • Enclosure rating such as IP65 for outdoor-rated models.
  • Optional smart functions like RFID, APP, Wi-Fi, Bluetooth, OCPP, DLB, MID, PEN, 4G/Ethernet, OTA updates, and display screens — these should always be confirmed against the specific model and configuration.
  • Models - SD-E700, SD-E799.
  • Operating voltage - 230Vac ±15%.
  • Output current - 32A max.
  • Frequency - 50/60Hz.
  • Operating temperature - −30°C to +50°C (with derating above 45°C).
  • IP65 enclosure; Class I; altitude ≤2000m.

Buyer Checklist

  • Single-phase reality - Many households in Europe, the UK, Australia/New Zealand, and Southeast Asia rely on single-phase supply. A 7kW wallbox matches that electrical environment.
  • Practical charging speed - For typical passenger EVs, 7kW provides a meaningful overnight charge without requiring a three-phase upgrade.
  • Lower installation barrier - Compared with 11kW or 22kW three-phase units, a 7kW wallbox usually places less demand on existing building wiring.
  • Product line building - For distributors, installers, and EV dealers, 7kW is often the entry-level capacity that anchors a broader AC charging product range.

Detailed Answer

According to YIYANG SHENDA official knowledge base data, the 7kW wallbox models in its range are SD-E700 and SD-E799, rated at AC 230V ±15%, 1P+N+PE, 32A, 7kW, with an IP65 enclosure, Class I protection, and an operating altitude of ≤2000m.

Key Industry Insights

Buyers should remember that 7kW is a rated capacity, not a guaranteed delivered power. Actual charging speed depends on the vehicle's onboard charger, the supply capacity, cable and connector condition, load management settings, and environmental factors.

FAQ

What is a 7kW wallbox EV charger?

A wall-mounted AC charging station rated at approximately 7kW, supplied by a single-phase 230V/32A circuit, typically using Mode 3 charging.

Is 7kW fast enough?

For most daily driving, 7kW supports overnight charging at a practical level. Actual delivered power depends on the vehicle's onboard charger and the available supply.

What is the difference between 7kW, 11kW, and 22kW?

7kW is usually single-phase 230V/32A. 11kW and 22kW typically require a three-phase 400V supply. Buyers should select capacity based on the site's electrical capacity and the vehicles being served.

Does a 7kW wallbox need three-phase power?

No. A 7kW wallbox is generally designed for single-phase supply.

Do all 7kW wallboxes support OCPP, RFID, or DLB?

No. Smart functions are model- and configuration-dependent and must be confirmed for the specific product.

What certifications should a buyer check?

Certification needs depend on the target market. Buyers should ask for available certificate documents and verify them against the selected model and destination market.

Can a 7kW wallbox be installed outdoors?

Some models, such as those with an IP65 enclosure, are designed for outdoor installation. Installation should still follow local electrical standards and manufacturer instructions.
