Start with the two ends of the charging connection
“AC charging gun” can mean the vehicle connector, the cable assembly, or a complete EV supply product. A useful selection begins with both ends: the connector that mates with the vehicle inlet, and the plug or fixed connection that interfaces with the site supply or charging equipment. Confirm each end for the destination market and the exact equipment configuration before comparing appearance or price.
This guide is a procurement worksheet for AC EVSE and cable configurations. It does not approve a building circuit, prove vehicle compatibility, or replace the applicable regional standard, installation assessment, or manufacturer documentation.
Map the connection before naming a connector
| Boundary | Record before quoting | Why it matters | Evidence to request |
|---|---|---|---|
| Destination market | Country or region, intended channel, and applicable product variant | Connector conventions and regulatory obligations vary by market | Market-specific configuration and compliance documents |
| Vehicle side | Exact vehicle models or approved inlet families, model years where relevant, and inlet evidence | A family name or a vehicle brand alone may not establish the actual inlet variant | Manufacturer documentation or an approved vehicle fitment record |
| Supply side | Portable or fixed equipment; intended supply interface and site conditions | The supply-side plug and the vehicle connector are different interfaces | Product configuration drawing and installation requirements |
| Electrical envelope | Available voltage, phase, current limit, and the supported equipment configuration | A connector shape or cable rating does not establish what the source, EVSE, or vehicle can deliver | Nameplate, configuration matrix, and model-specific operating limits |
| Use and handling | Indoor/outdoor exposure, frequency of movement, storage, and who manages the cable | These needs affect the product arrangement and validation questions, not just connector choice | Intended-use statement and relevant construction documentation |
| Delivery evidence | Required declarations, test reports, markings, and traceability for the market | A logo or generic certificate title does not establish scope for the exact model | Complete document with issuer, model/configuration, standard edition, and validity scope |
For standardized AC accessories, IEC 62196-2 describes dimensional compatibility requirements for plugs, socket-outlets, vehicle connectors and vehicle inlets. Its published page also names a 2025 edition as newer than the 2022 edition. That is a reason to check the current edition and its applicability for the target market—not a claim that one interface is accepted everywhere. IEC 62196-2 publication record
Match the vehicle end to the market
Start with the exact inlet specification for the vehicle population you intend to serve. If a fleet mixes models, list them separately and record the source for each inlet. Do not infer a connector from a vehicle badge, a sales-region assumption, or a photograph alone. Where adapters are in scope, treat each adapter as a separate configuration requiring its own compatibility and approval evidence.
Regional examples must stay regional. The US Department of Energy's Alternative Fuels Data Center describes SAE J1772 and NACS for US charging contexts; those descriptions do not establish compatibility or market requirements in other countries. Its consumer guidance also tells buyers to check connector compatibility for the vehicle under consideration. DOE AFDC connector guidance
If the buyer cannot provide an exact vehicle list, write down the uncertainty as an open fitment question. A proposed connector family can be used to request a quotation scenario, but should not be presented as confirmed fitment.
Check the supply end and the power path
The vehicle connector alone does not define a complete charging product. Record whether the product is a portable cordset, an in-cable control-and-protection device, a socketed EVSE, or a tethered unit. Identify its supply-side plug or fixed wiring arrangement separately from its vehicle connector.
For AC charging, the vehicle's onboard charger converts incoming AC energy for the traction battery. The Department of Energy explains this distinction in its federal fleet EVSE material. As a result, the usable configuration depends on more than the cable label: the supply, EVSE limits and vehicle onboard charger all matter. DOE Federal Fleet EVSE overview
Use this comparison only as a data-collection aid:
| Check | Configuration A | Configuration B | Selection rule |
|---|---|---|---|
| Destination market and vehicle list | Record source | Record source | Stop if the intended vehicles or market are unresolved |
| Vehicle connector and inlet | Exact variant and evidence | Exact variant and evidence | Match each intended vehicle; do not rely on a broad label |
| Supply interface | Plug or fixed connection | Plug or fixed connection | Confirm against the actual site or use case |
| Voltage, phase and current | Manufacturer-stated limits | Manufacturer-stated limits | Use the narrowest applicable system limit; confirm with qualified site professionals where installation is involved |
| Product construction | Cable assembly, control unit, enclosure and storage arrangement | Same fields | Compare documented configurations rather than marketing names |
| Market evidence | Document, issuer, edition, model and scope | Same fields | Require evidence that names the offered configuration and intended market |
Do not multiply a connector's headline current by a nominal voltage and call the result a guaranteed charge rate. The source, EVSE configuration, vehicle limit, installation and operating conditions may impose lower limits. A calculation is meaningful only after the compared ratings are defined for the same configuration and boundary.
Turn a preference into a quote-ready request
Before requesting samples or a commercial offer, send a concise configuration record:
- Destination country or region and intended sales channel.
- Vehicle makes, models and verified inlet information, or a clear note that fitment is still unknown.
- Portable, socketed or tethered product arrangement, plus the separately identified supply-side interface.
- Intended supply conditions and the electrical limits already confirmed by the responsible site professional.
- Expected handling and storage context, including whether the cable is moved routinely or remains at one location.
- The exact documents needed for the market, with the required model/configuration and standard edition identified.
- Sample checks that will be performed against the approved drawing, labels and document set.
Ask the supplier to identify unanswered fields explicitly. “Universal,” “compatible,” “certified,” or a connector photograph does not close a missing model, market, electrical or evidence question. Do not request or accept a broad claim where the actual configuration remains unnamed.
Frequently asked questions
Is the vehicle connector enough to select an AC charging cable?
No. Also identify the supply-side interface, equipment arrangement, intended market and electrical configuration. Then confirm the exact vehicle fitment and required evidence.
Can I use one AC connector type worldwide?
Do not assume that. Connector use and compliance depend on the target market and intended configuration. Confirm the applicable regional requirements and vehicle population before fixing a product variant.
Does a higher cable current rating mean faster charging?
Not by itself. The complete system and vehicle limits matter, and an electrical installation must be assessed for its actual conditions. A cable rating does not guarantee delivered charging power.
What should I send for an initial configuration review?
Share the destination market, intended vehicle models or inlets, supply-side arrangement, use case and the documents you need. If a field is unknown, label it as unknown instead of guessing.
Discuss an AC charging configuration with SUPERGENIE. Share only authorized, non-sensitive configuration information. A review request does not itself establish compatibility, compliance or installation suitability.
