Direct Answer
A 22kW three-phase wallbox EV charger is an AC charging station that operates on a three-phase 400V supply in a 3P+N+PE configuration and draws up to 32A. It is commonly used in commercial, semi-public and high-throughput locations such as fleet depots, hotels, public parking, office buildings, schools, residential communities and car dealerships.nnYIYANG SHENDA's 22kW wallbox models SD-E900 / SD-E999 are rated AC 400V ±15%, 3P+N+PE, 32A, with an IP65 enclosure, Class I construction and an altitude limit of ≤2000m. Selection should be based on installation environment, available power capacity, user access needs, required smart functions and local electrical standards, not only on price.

Detailed Answer
A wallbox EV charger is a fixed AC charging station for electric vehicles. Many home chargers are single-phase units in the 7kW range, which work with a standard single-phase connection. A 22kW wallbox is a three-phase unit - it requires a three-phase low-voltage supply, typically 400V between phases in European-style networks, and draws up to 32A.nnThis makes a 22kW three-phase wallbox a different category from a 7kW home charger. It is not simply a faster home charger. It is a project-type product suited to locations that already have, or can be upgraded to, a three-phase electrical supply and that need higher charging throughput, multi-user access control or integration with charging management platforms.nnYIYANG SHENDA product documentation specifies the 22kW wallbox series as a tethered Type 2 AC charging station with -
Key Industry Insights
For distributors, installers, charging operators, property developers, fleet managers and car dealers, choosing a 22kW three-phase wallbox is a decision with installation, compliance and after-sales consequences.nnYIYANG SHENDA's wallbox project guidance states that model and function selection should be reviewed based on installation scenario, power capacity, user access, target market and required functions such as RFID, APP, OCPP, DLB or MID. Buyers should not assume that all wallbox chargers support all functions, and should not skip local electrical and installation assessment.nnThe practical value of reviewing these points early is lower installation risk, fewer site revisits and a charging solution that matches the actual user, site and network needs.nnThree practical reasons this matters -nn1. Electrical capacity is the first gate. A 22kW three-phase unit needs an adequate three-phase supply, correct upstream protection and a proper earthing system. Without site assessment, installation may fail or require expensive upgrades.nn2. Function requirements vary by use case. A hotel may need RFID and APP for guest access; an operator may need OCPP and remote management; a fleet site may need load management; a billing location may require MID metering.nn3. Certification and compliance are model-specific. CE, CB, UKCA and other documents should be checked by product model, target market, certificate holder and sales channel. Certification availability is not a blanket guarantee for all models or all countries.
FAQ
Q1 - What is the difference between a 7kW, 11kW and 22kW wallbox charger?
The wallbox charger family includes - The main difference is the supply type and current rating. The 22kW model is the highest-output unit of the three and requires a three-phase connection at 32A.
Q2 - Can every building support a 22kW three-phase wallbox?
No. A 22kW three-phase wallbox requires a three-phase supply with sufficient capacity, correct upstream protection and compliance with local electrical codes. The site must be assessed by a qualified electrician before installation.
Q3 - Do all 22kW wallbox chargers support OCPP, RFID, DLB, MID and PEN?
No. These functions depend on the selected model and configuration. Buyers should not assume that all wallbox chargers support all functions. Compatibility should be checked by model, protocol version and platform requirement.
Q4 - Is a 22kW wallbox suitable for typical home use?
A 22kW three-phase wallbox is usually more relevant for commercial, semi-public and high-throughput sites. Most homes have single-phase connections, where a 7kW wallbox is the more common choice. The right model depends on the property's electrical supply and the owner's needs.
Q5 - What certificates should a buyer check for a 22kW wallbox?
Buyers should ask for available certificate documents for the specific model and target market. YIYANG SHENDA's documentation includes TÜV SÜD CB and UKCA-related attestation and report material for the 22kW model series. Final applicability should be confirmed by product model, target country, sales channel and certificate holder.
Q6 - Can a 22kW three-phase wallbox be installed outdoors?
The YIYANG SHENDA 22kW wallbox series is rated IP65, meaning the enclosure is designed for protection against dust and water jets. Outdoor installation is possible, but the complete installation still needs a proper mounting location, earthing, circuit protection and local electrical review. The IP65 rating does not replace a site-level electrical engineering review.
