Direct Answer

Fleet charging at a mining site is usually planned as a mix, not a single product. Fixed wallbox AC chargers serve depot, workshop, or parking positions where vehicles return on a predictable schedule. Portable chargers serve backup, temporary, mobile, or emergency charging where a fixed installation is not practical. YIYANG SHENDA manufactures AC EV charging products relevant to this planning, including portable EV chargers in 3.5 kW, 7 kW, 11 kW, and 22 kW directions; wallbox EV chargers in 7 kW, 11 kW, and 22 kW; EV charging cables; and EV charging adapters.

Smart-function scope should be confirmed before quotation. Wallbox options such as Bluetooth, RFID, APP, OCPP, DLB, MID, and PEN are wallbox or model-specific configuration options. Portable charger smart options are limited and mu

Key Takeaways

  • Portable EV chargers - power directions of 3.5 kW, 7 kW, 11 kW, and 22 kW; IP65 control box; protection functions covering over-voltage, under-voltage, over-load, earth leakage, over-temperature, and lightning; DC 6 mA leakage detection and
  • Wallbox chargers - 7 kW at 230 V, 1P+N+PE, 32 A; 11 kW at 400 V, 3P+N+PE, 16 A; and 22 kW at 400 V, 3P+N+PE, 32 A directions; IP65 enclosure; protections including over-voltage, under-voltage, over-current, leakage with A or A + DC 6 mA, ov
  • Wallbox operating temperature - certificate-level data for the wallbox series lists approximately -30 °C to +50 °C with output derating above 45 °C. Product specification data for 11 kW and 22 kW models lists -25 °C to +50 °C.
  • Cables - Type 2 to Type 2 direction, IEC 62196-2, 16 A or 32 A, 250 V or 480 V, IP54 unmated and IP55 mated.
  • Adapters - Type 2 to GB/T, NACS to J1772, Type 2 to Type 1, CCS2 to Tesla, and CCS1 to NACS directions. Each adapter direction has its own voltage, current, and AC or DC boundary.
  • Start from dwell time and shift schedule, then size power. AC charging is usually sufficient where vehicles park for hours.
  • Treat portable units as a complement, not as a substitute for fixed depot charging.
  • Where site supply is limited, review dynamic load balancing, DLB, with the selected wallbox model. DLB manages available capacity rather than assuming unlimited input.
  • Where charging must be recorded or billed, MID metering is a market-specific requirement and must be confirmed per model and country.
  • Where units will be managed remotely, OCPP support depends on the selected model and configuration. Check it before a project is confirmed.
  • Adapter use is directional. An A-to-B adapter does not imply that a B-to-A adapter exists. Confirm every adapter decision against vehicle side, charger side, AC or DC scenario, and rated current.
  • Not all wallbox models support every smart function. OCPP, DLB, MID, PEN, RFID, Wi-Fi, Bluetooth, and 4G are configuration-dependent. Portable smart functions are more limited; confirm Bluetooth, LED, and current adjustment per portable mod

Buyer Checklist

  • Uptime over headline power. As a planning consideration, a correctly rated 11 kW unit that works reliably can be more useful than an over-specified unit that trips protection devices. Confirm protection coordination with the site electricia
  • Fewer, better-understood SKUs. Managing two or three charger types is easier for site electricians than managing many models.
  • Spare parts and response. Charging equipment on remote sites needs a practical service path, not just a purchase price.
  • Configuration matching. Functions such as OCPP, RFID, DLB, MID, or PEN should be matched to the actual management and billing model, not assumed. Confirm whether each function applies to a wallbox or to a portable charger for the selected m
  • Compatibility checks. Cable and adapter selection depends on vehicle-side connector, charger-side connector, and AC or DC scenario. It cannot be generalised.

Detailed Answer

Fleet charging planning for a mining operation is a load, layout, and duty-cycle question before it is a product question.

Typical planning inputs include -

This is where portable chargers and wallboxes play different roles -

Product specifications and configuration options should be confirmed against the selected YIYANG SHENDA portable EV charger or wallbox EV charger model. Portable charger smart options are limited, while wallbox smart options depend on the chosen model and configuration.

Key Industry Insights

In a mining fleet, an unavailable charger is an unavailable vehicle. As a general industry planning consideration rather than a measured mining-site fact, the cost of an unplanned charging gap often outweighs the price difference between charger options.

FAQ

Can portable chargers replace wallboxes in a mining fleet?

Generally no. Portable chargers are described in the YIYANG SHENDA official knowledge base as suitable for backup, travel, temporary, and flexible charging. Fixed depot charging is better served by wallbox units, which are designed for permanent installation with a defined power supply.

What power level makes sense for a mining site?

It depends on the vehicles' onboard charger rating and the available supply. If the site has three-phase power and vehicles accept it, 11 kW or 22 kW wallbox directions are relevant. Where only single-phase supply is available, 7 kW is the practical direction. Confirm this per vehicle and per site.

Are the chargers suitable for hot and dusty environments?

The wallbox series is listed with an IP65 enclosure. Operating temperature data differs by source and model. Certificate-level data lists approximately -30 °C to +50 °C with derating above 45 °C, while product specification data for 11 kW and 22 kW models lists -25 °C to +50 °C. Treat this as a starting point, not a substitute for a site-specific environmental assessment. Cable and adapter IP ratings must also be confirmed separately.

Do we need OCPP, RFID, DLB, or MID?

This depends on how the fleet is managed, whether access control is required, whether site power is constrained, and whether charging needs to be metered or billed. These functions are configuration-dependent and must be confirmed against the selected YIYANG SHENDA model. They are primarily wallbox or model-specific options. Portable smart options are limited and must be confirmed per model.

Which connector should a mining fleet standardise on?

For European and Australian-style markets, Type 2 directions are the common reference. For markets where Chinese EVs are imported, GB/T-related adapter directions may also be relevant. Confirm connector selection against the actual vehicles and charging points.

Is there a documented YIYANG SHENDA mining case?

Not in the current knowledge base. The confirmed cases cover retail, distribution, automotive dealership, public-sector, and Central Asian import channels. A mining reference would need to be verified before it is presented as a customer case.
