Direct Answer
For European public EV charging projects, the first step is usually not price, but documentation review, certificate verification by product model and target market, proof testing, and model selection. YIYANG SHENDA supports portable EV chargers and wallbox EV chargers with available certificate documents, specifications, manuals, function lists, and proof review for selected models, based on the company's official knowledge base. Project evaluation criteria, local electrical standards, installation practice, and acceptance approval remain with the buyer, importer, installer, and the responsible authorities.
Key Takeaways
- Public project support is described in the official knowledge base as documentation, configuration review, proof testing, and delivery support — not as a guarantee of tender award or regulatory approval.
- Certificate applicability must be confirmed by product model, target country, sales channel, certificate holder, authorization method, and validity period.
- Wallbox model selection should follow installation scenario, power capacity, user access method, and required functions such as RFID, APP, OCPP, DLB, or MID.
- Functions such as OCPP, DLB, MID, and PEN are handled as model-and-configuration checks in the official knowledge base, not as defaults across all wallbox models.
- A documentation package for project review typically includes certificates, inspection reports, specifications, manuals, a function list, and factory introduction material.
- proof testing or a small pilot batch is the recommended step before a bulk delivery in project-type cooperation.
- Installation, wiring, local electrical standards, and site acceptance remain the responsibility of the local installer and the responsible authorities.
- Project timelines and delivery planning should be confirmed after the model, function set, quantity, and documentation requirements are fixed.
- Public project participation requires careful handling of entity naming - legal entities and certificate holders should be quoted as they appear on the original documents.

Detailed Answer
European public projects — power companies, municipal or government-related buyers, construction projects, public parking, and similar infrastructure — typically run a long procurement chain with several participants - end user, technical specifier, purchasing department, installer, and sometimes an energy service company.
According to YIYANG SHENDA official knowledge base, the practical support scope for such projects is a review-and-supply scope rather than an approval scope. It normally covers -
Product-side, the knowledge base describes two main categories used in this type of project -
The documented wallbox model groups in the official knowledge base are -
Common documented characteristics for these wallbox groups include operating temperature −30°C to +50°C with derating above 45°C, Class I protection, IP65 enclosure, and altitude ≤2000m. Project-specific configuration still needs to be confirmed case by case.
Key Industry Insights
Public procurement risk is rarely about a single unit price. It is about whether the documents hold up at every stage of the chain.
If a certificate is submitted for the wrong model, wrong market, or wrong certificate holder, the problem often appears late — during tender review, import registration, installation, or acceptance — when correction is expensive.
According to YIYANG SHENDA official knowledge base, several certificate types used in European markets are attestations or voluntary verification documents, and they do not by themselves replace a manufacturer's Declaration of Conformity or automatically permit CE or UKCA marking. Examples documented in the knowledge base include -
The knowledge base also states clearly that a VoC is a voluntary basis and does not mean all essential requirements of a Declaration of Conformity are automatically satisfied, and that an Attestation does not replace a national Declaration of Conformity.
For project buyers, this means the useful question is not "do you have certificates?" but "which certificate document applies to this exact model, in this exact country, for this exact sales and installation channel?"
FAQ
What documents are usually requested at the first project review stage?
According to YIYANG SHENDA official knowledge base, a typical package includes available certificate documents for selected models, inspection reports, product specifications, manuals, a function list, and basic factory information. The exact list depends on the tender or technical requirement document provided by the project side.
Can the same certificate be used for every European country?
No blanket answer applies. The official knowledge base states that certification documents should be reviewed by product model, target market, sales channel, certificate holder, and authorization method. Additional national requirements may apply even where an EU-level document exists.
Does every wallbox model support OCPP, DLB, MID, or PEN?
No. The official knowledge base treats these as configuration-dependent items that must be confirmed for the specific model and project. Buyers should not assume that a function listed as a product direction is included on every unit.
Do attestations and VoC documents allow CE or UKCA marking by themselves?
According to the official knowledge base, an Attestation does not replace an EU or UK Declaration of Conformity and does not itself permit CE or UKCA marking. A VoC is a voluntary basis and does not automatically mean all essential requirements are met. Technical documentation and a manufacturer's Declaration of Conformity are still needed.
How should adapter and connector compatibility be handled in a public project?
Adapter compatibility must be reviewed by vehicle-side connector, charger-side connector, AC or DC scenario, rated current, voltage, vehicle model, and target market. Direction matters - the existence of one adapter direction does not imply the reverse direction is available.
Is there a reference case for European public projects?
The official knowledge base describes a desensitized case involving European public project customers, where portable and wallbox chargers moved through project scoping, technical document review, proof testing, certification confirmation, and batch delivery, for applications such as public parking, fleets, residential buildings, and energy service projects. Client identity details are withheld, and the outcome should not be treated as a general promise for other projects.
What still needs to be checked before publishing project-facing material?
Dynamic external items must be verified against official or authoritative sources at the time of publication, with a Last Updated note. These include European regulatory and market-access topics such as AFIR, ISO 15118, Eichrecht, §14a EnWG, BS 7671, national registration schemes, and any subsidy or tender-specific rule. The knowledge base classifies these as dynamic external evidence and does not treat them as stable company facts.
