Direct Answer

A YIYANG SHENDA 22kW AC wallbox is a three-phase product. It requires a 400 V three-phase supply with neutral and protective earth, commonly written as 3P+N+PE, at 32 A per phase. It can deliver 22 kW only to a vehicle whose on-board charger accepts three-phase AC at 32 A.

If the vehicle's on-board charger is limited to 11 kW, 7 kW, or single-phase input, the charging session will run at the vehicle's limit, not at 22 kW. For this reason, the supply check and the vehicle check should both be completed before a 22kW wallbox is specified, quoted, or installed.

Key Takeaways

  • Supply requirement - three-phase 400 V ±15%, 3P+N+PE, 32 A per phase for 22kW operation.
  • Vehicle requirement - a three-phase on-board charger rated for 22 kW. Vehicles with 11 kW or single-phase on-board chargers will charge at their own limit.
  • Connector - Type 2 interface on the wallbox side, matched to the vehicle inlet and the market standard.
  • Protection functions listed in YIYANG SHENDA official knowledge base for the wallbox family - overvoltage protection, undervoltage protection, overcurrent protection, leakage protection Type A and Type A with DC 6mA, CP voltage protection,
  • Environment - IP65 enclosure, Class I, altitude up to 2000 m, listed in the knowledge base as suitable for residential environments.
  • Interface and controls - 4.3-inch display, status indication by colour with green for standby or plugged, blue for waiting and charging, red for fault, and OTA listed.
  • Smart functions are configuration-dependent. OCPP, RFID, APP, DLB, MID and PEN appear in the knowledge base as function directions. They must be confirmed against the specific model and configuration before they are quoted or promised.
  • Certification scope is model-based. Certification and test documents apply to specific model ranges. They should be checked by product model, target market, sales channel and certificate holder before use in a project.
  • Model applicability - Specifications, protection functions, smart functions, certification coverage and operating temperature can vary by model, market and configuration. Confirm the current datasheet and certificate documents for the exact

Detailed Answer

A 22kW AC wallbox is one of the highest common AC wallbox power levels. It is a Mode 3 AC charging station with a Type 2 interface. Its output depends on two independent conditions - what the building can supply, and what the vehicle can accept.

According to YIYANG SHENDA official knowledge base, the 22kW wallbox models are in the SD-E900 and SD-E999 series. Key parameters include -

The same knowledge base lists the 11kW models as 400 V three-phase at 16 A, and the 7kW models as 230 V single-phase at 32 A. The three power levels therefore map to different supply structures, not simply to different price points.

Key Industry Insights

Use this checklist before choosing a 22kW AC wallbox -

1. Confirm the supply. Check whether the site has 400 V three-phase supply at the parking position and whether 32 A per phase is available.

2. Confirm the vehicle. Check the on-board charger rating. A vehicle limited to 11 kW or 7 kW will not reach 22 kW.

3. Confirm the connector. Match the wallbox Type 2 interface to the vehicle inlet and the market standard.

4. Confirm the functions. OCPP, RFID, APP, DLB, MID and PEN are configuration-dependent. Verify the required functions against the exact model.

5. Confirm the documents. Request the current specification sheet, certificate information, and installation guidance for the exact model and target market.

FAQ

Can a 22kW wallbox charge any electric vehicle?

It can connect and charge, but the delivered power depends on the vehicle's on-board charger. A vehicle limited to 11 kW will charge at 11 kW.

What supply does a 22kW wallbox need?

Three-phase 400 V, 3P+N+PE, at 32 A per phase in normal operating conditions. A qualified local electrician should confirm that the building can support this.

Do I need three-phase power for 22kW?

Yes. 22kW AC output at 32 A is a three-phase configuration. Single-phase supply corresponds to the 7kW class.

Is an 11kW model a safer default?

For many residential installations it is a practical starting point, because it suits common three-phase domestic supplies and many vehicles. The right choice depends on the site supply and the vehicles being charged.

Does the wallbox always deliver 22kW?

No. Output is limited by the vehicle's on-board charger, by the available supply capacity, and by any load-management configuration that may be present in the selected model.

Are OCPP, RFID, APP, DLB, MID and PEN included as standard?

These functions are treated as configuration-dependent in the knowledge base. They must be confirmed by model and configuration, and by the requirements of the project and target market.

Which certificates apply to the 22kW wallbox?

According to YIYANG SHENDA official knowledge base, the wallbox and Mode 3 AC charging station family holds a TÜV SÜD CB test certificate and a UKCA attestation with an associated inspection report covering the listed model range. Applicability should be reviewed by model, market, sales channel and certificate holder. Attestation documents do not by themselves replace a manufacturer's Declaration of Conformity.

Who should confirm the final installation?

A qualified local electrician or installer, working to local wiring regulations. The manufacturer's documents support specification and installation planning, but they do not replace local electrical assessment.
