Direct Answer
Wi-Fi and app control on AC EV chargers are configuration options rather than default features. Before ordering, buyers should confirm six things - which connectivity is actually built in, whether the app is supplier-hosted or customer-branded, which protocol the charger uses to communicate with a backend, how user access is managed, whether firmware can be updated remotely, and whether the wireless module changes the certification route for the target market.
In YIYANG SHENDA product documentation, smart functions such as APP, Wi-Fi, Bluetooth, 4G, OCPP, DLB, MID and PEN are treated as function-direction items rather than fixed features. Each one therefore has to be confirmed by specific model and configuration before it is presented as a standard product capability.
Key Takeaways
- Local wireless link. Wi-Fi or Bluetooth, used for setup, current adjustment, or local monitoring.
- Wide-area link. 4G or Ethernet/LAN, used when the charger is not on a managed Wi-Fi network.
- Platform protocol. A protocol such as OCPP, which determines whether the charger can be operated by a charging management system, often shortened to CSMS.
- User identification. A mobile app account, an RFID card, or both.
- Firmware updates. Whether over-the-air updates are supported, and who controls them.
- Metering. Whether billing-grade measurement is required, which is a separate question from app features.

Detailed Answer
"Connected charger" is a broad label. Several layers can be present or absent independently, and each layer should be confirmed by specific model and configuration -
A charger can support Bluetooth without an app. It can support an app without OCPP. It can support OCPP without Wi-Fi, using 4G or LAN instead. Buyers who treat these as one bundle often order the wrong configuration.
YIYANG SHENDA product data illustrates the point. The wallbox range lists Bluetooth/Wi-Fi as optional and includes OTA plus a 4.3-inch display among its listed key benefits, while one YIYANG SHENDA portable EV charger model lists Bluetooth as available and APP control as not available. Portable and wallbox products do not carry the same connected feature set, and even within one product family the features remain configuration-dependent.

FAQ
Is Wi-Fi standard on all wallbox chargers?
No. YIYANG SHENDA product data lists Bluetooth/Wi-Fi as optional on the wallbox range. Availability should be confirmed per model and configuration.
Do I need OCPP if I have an app?
Not necessarily. An app can control a charger locally or through a supplier cloud service without OCPP. OCPP matters when a third-party charging management system needs to operate the charger. YIYANG SHENDA product documentation states that OCPP support depends on the selected wallbox model and configuration.
Can the app carry our own brand?
App branding is a customization topic. It should be reviewed together with the model, market, quantity, and certificate implications rather than assumed.
Does an RFID reader mean the charger is networked?
Not automatically. RFID is a user authentication function; it does not by itself confirm remote connectivity or backend integration.
Will adding Wi-Fi change our certification?
Wireless modules can bring radio equipment requirements into scope. The current certificate documents should be reviewed by model and target market to confirm what is covered.
What should we test on the proof?
Pairing and account setup, network behaviour on the buyer's own router, offline charging behaviour, RFID if applicable, and, for operator projects, connection to the intended backend.
Who supports the app after delivery?
This should be defined in writing before ordering. It is common for first-line support to sit with the distributor, with escalation to the factory or platform provider.
Can a portable charger be app-controlled?
It depends on the model. Some YIYANG SHENDA portable models list Bluetooth but not APP control. Buyers should check the specific model rather than the category.
