Direct Answer
A 22kW AC wallbox with a Type 2 connector is a three-phase AC charging unit designed around a 400V, 3P+N+PE supply and a 32A maximum output, as described in YIYANG SHENDA official knowledge base data for the SD-E900 / SD-E999 models.
When selecting one, buyers should evaluate four things together rather than separately - the electrical platform (three-phase 400V, 32A), the display and user interface, the protection set, and the connectivity options actually confirmed for the specific model.
Display, protection and connectivity features are configuration-dependent.
Key Takeaways
- Confirm the electrical platform first. 22kW corresponds to three-phase 400V, 3P+N+PE, 32A in the SD-E900 / SD-E999 configuration.
- Treat the display as a usability feature, not a compliance feature. The listed 4.3-inch HCI display supports status visibility and on-unit interaction.
- Read the protection list line by line. Overvoltage, undervoltage, overcurrent, leakage (Type A / Type A + DC 6mA), CP voltage, overtemperature, lightning, relay sticking and grounding are listed for the family; confirm what applies to the e
- Verify connectivity by model and configuration. OTA and Bluetooth/Wi-Fi optional are listed; RFID, OCPP, DLB, MID, PEN, APP, 4G and Ethernet must be checked for the specific unit.
- Check certificate scope, not certificate presence. YIYANG SHENDA official knowledge base lists a TÜV SÜD CB Test Certificate (SG PSB-EH-00179 / CBS 135824 0002 Rev. 00) covering tethered models SD-E900, SD-E999, SD-E800, SD-E899, SD-E700, S
- Match enclosure and environment. The certificate index lists IP65 enclosure, Class I, altitude ≤2000m and residential environments, with declared operating range around −30°C to +50°C and derating above 45°C. The product specification sheet
- Check dimensions and cable lengths. Listed body size is approximately 295 × 195 × 95.5 mm, input line 1 m, output line 5 m.
- Design standard reference. IEC 61851-1 and IEC 62196-2 are the referenced design standards in the wallbox specification index.
Buyer Checklist
- Installation fit - A 22kW unit requires a three-phase supply and adequate site capacity. Installation scenario, power capacity and local electrical standards are review points before confirmation, per YIYANG SHENDA official knowledge base g
- After-sales pressure - Protections such as residual current handling, overtemperature management and grounding behaviour influence field behaviour and service load.
- Project and platform requirements - For operators and project buyers, OCPP version and back-end compatibility need checking by model, protocol version and platform requirement.
- Documentation - Certificate scope must be matched to the exact model, target country, sales channel and certificate holder.
Detailed Answer
"22kW" describes a power class, not a complete specification. Several other parameters determine whether the unit fits a given installation and market.
Power and supply basis
This means a 22kW wallbox is a three-phase product. A single-phase 230V supply corresponds to the 7kW class in the same product family.
Display and interface
Protection set
The specification index in the YIYANG SHENDA official knowledge base lists overvoltage protection (≥270V), undervoltage protection (≤85V), overcurrent protection (≥110% of rated output), leakage protection (Type A, or Type A + DC 6mA), CP voltage protection (≥±1V), overtemperature protection (85°C protection / 65°C resumption), lightning protection, relay sticking protection and grounding.
Connectivity
Key Industry Insights
The same "22kW Type 2 wallbox" label can cover units with different protection architectures, interface levels and communication capabilities. Buyers who compare only power class and price may end up with a unit that does not match the installation, the back-end, or the local documentation requirements.
FAQ
Does a 22kW wallbox need a three-phase supply?
Yes, in the configuration described by YIYANG SHENDA official knowledge base - 22kW is listed as AC 400V ±15%, 3P+N+PE, 32A. Single-phase 230V corresponds to the 7kW class in the same family.
Does every 22kW Type 2 wallbox support OCPP, RFID, DLB, MID or PEN?
No such blanket statement should be made. According to YIYANG SHENDA official knowledge base, these are function directions that must be confirmed for the specific model and configuration, and OCPP compatibility should be checked by protocol version and platform requirement.
Is the display standard?
The listed configuration includes a 4.3-inch HCI display. Display type and interface details should be confirmed against the current model specification.
Which certificates apply to the 22kW models?
The knowledge base lists a TÜV SÜD CB Test Certificate and a TÜV SÜD UKCA Attestation covering the tethered SD-E900, SD-E999, SD-E800, SD-E899, SD-E700 and SD-E799 group, under the trademark TIMEYES. Applicability still depends on product model, target market, sales channel, certificate holder, authorization method and validity period.
Will a 22kW charger always deliver 22kW?
Not necessarily. Output depends on the vehicle's onboard charger limit, the available supply, load management settings, and thermal derating. The knowledge base notes derating behaviour above 45°C for the covered certificate configuration.
What should be verified before ordering?
Supply type and phase count, site capacity and installation review, required protections, display/interface level, connectivity and back-end compatibility, certificate scope for the destination market, enclosure rating and cable length, and the latest specification sheet. *Fact-check note - The knowledge base lists different operating temperature ranges for the 22kW wallbox in the certificate index (−30°C to +50°C, derating above 45°C) and in the product specification sheet (−25°C to +50°C). Confirm the current specification sheet, and confirm which connectivity and protection features apply to the exact model, before final selection. Market-specific regulatory statements should be verified against current official sources at the time of purchase.*
