Direct Answer
A 22kW portable EV charger should be judged by its protection design first, not only by its power rating. For YIYANG SHENDA buyers, the practical checklist is - over-voltage protection, under-voltage protection, over-load and over-current protection, earth leakage protection with DC residual current handling, over-temperature protection and temperature monitoring, lightning and surge protection, grounding or earth continuity monitoring where included, a sealed control box with an IP rating, and a durable enclosure with safe connector and cable behaviour.
According to the YIYANG SHENDA official knowledge base, the portable EV charger range covers 3.5kW, 7kW, 11kW and 22kW output power directions.
Key Takeaways
- Distributors and retailers - a weak protection set can turn into a stream of returns and installation complaints.
- E-commerce sellers - leakage and thermal issues tend to appear in reviews rather than in lab tests.
- Installers and electrical contractors - protection behaviour, earth monitoring and residual current design must fit local wiring rules.
- EV dealers and fleet buyers - portable chargers are often used as backup or delivery accessories, where misuse and rough handling are common.
- Project and public buyers - documentation of protection functions and test evidence is usually part of the review file.

Detailed Answer
A portable EV charger is a power electronics product that a driver may connect to an everyday socket, a CEE outlet or another AC supply. Protection features exist to manage three risk groups -
For a 22kW rating, these risks matter more than on a small unit because current levels and thermal load are higher. In practice, a 22kW portable charger usually relates to a three-phase supply rather than a single-phase household socket. Buyers should verify input voltage, phase configuration and plug type together with the protection list.
According to the YIYANG SHENDA official knowledge base, the Model 2 portable EV charger listing shows an input voltage range of 100V–240V or 185V–480V, output power of 3.5kW / 7kW / 11kW / 22kW, output current of 16A / 32A, IP65 operating environment, an operating temperature of -25°C to +50°C, and natural air cooling.
Key Industry Insights
Protection features affect the cost of ownership more than the price tag suggests. They influence returns, warranty claims, installation costs and, in some channels, whether the product can be sold at all.
Protection also interacts with certification. Many portable EV chargers with an in-cable control box fall under Mode 2 / IC-CPD, but the exact charging mode should be confirmed by model. According to the YIYANG SHENDA official knowledge base, the IC-CPD certificate series lists test standards including EN IEC 62752:2024 and IEC 62752:2024, and EMC-related testing under EN IEC 61851-21-2:2021.
FAQ
Does a 22kW portable charger need the same protection as a wallbox?
Not necessarily the same configuration. Wallbox and portable charger product categories have different construction and different use cases. According to the YIYANG SHENDA official knowledge base, wallbox specifications list protection items such as over-voltage, under-voltage, over-current, leakage protection with A / A + DC 6mA options, CP voltage protection, over-temperature with protection and resumption temperatures, lightning protection, relay sticking detection and grounding. Portable charger specifications should be read from the portable model data, not copied from the wallbox list.
Is IP65 enough for outdoor use?
IP65 is a starting point and covers dust and water jet exposure for the enclosure. Actual suitability depends on installation position, weather exposure and local rules. Confirm the rated position rather than assuming full outdoor operation.
Can a 22kW portable charger run on a normal household socket?
A 22kW output implies high current and usually a three-phase supply. Buyers should confirm the input voltage range, plug type and required circuit protection for the target market. This is a selection decision, not a marketing claim.
Are all YIYANG SHENDA portable models covered by the same certificates?
No blanket statement should be made. The knowledge base lists IC-CPD certificate coverage for a defined model series SD-Eaaa through SD-Eggg with specific parameters. Coverage must be checked model by model, and certificate use depends on the certificate holder, target market and sales channel.
Do protection features replace professional installation or a local electrical check?
No. Protection features manage defined fault conditions. They do not replace local electrical assessment, correct circuit design or installer judgement.
What should a distributor ask first?
Start with three questions - which exact model, which market and plug type, and which certificate scope applies. Protection values, temperature limits and IP ratings should then be read from that model's specification sheet.
