Wireless EV charging (inductive charging) is moving from pilot projects into real deployments in public parking, fleet depots, buses, logistics hubs, and smart roads. The value is clear: smoother user experience, fewer exposed contacts, and reduced wear from repeated plug-in cycles.

But even when power transfer is wireless (coil-to-coil), the system still uses connectors across multiple modules:

• AC input & power conversion (cabinet/inverter/rectifier sections)
• Ground pad module power (aux power, coil module wiring, internal distribution)
• Control & communication (controllers, interlocks, monitoring)
• Sensors (temperature, alignment, foreign object detection, diagnostics)
• Maintenance/service (fast swap modules, sealed outdoor interfaces )

That’s why connector selection becomes critical—especially outdoors, where water, dust, vibration, and UV exposure are constant.

Where Connectors Are Used in a Wireless EV Charging System

Wireless EV charging requires both power connectors and signal/sensor connectors, designed for outdoor reliability. A typical wireless EV charging deployment includes three main zones:

Power cabinet/roadside control box

Where grid power enters and is managed. Connectors commonly support:

• Power feed to pad modules
• Cabinet wiring access and internal connection points
• Monitoring, communication, and service interfaces

Ground pad (charging transmitter)

Even though the pad transmits power wirelessly, it still needs wiring for:

• Pad module power and grounding
• Temperature sensing and status signals
• Enclosure interfaces and maintenance access

Vehicle-side receiver and harness interfaces

The receiver coordinates charging and system safety. Connectors support:

• Low-voltage control and diagnostics
• Sensor signals and safety interlocks
• Robust harness connections under vibration and road splash

What Matters Most for Wireless EV Charging Connectors

Common requirements include:

• IP67/IP68 waterproof sealing (rain, washdown, road spray)
• Anti-vibration locking (vehicles, pads, roadside cabinets)
• Fast installation & maintenance (module replacement, field work)
• Multi-pin and hybrid connections (power + signal + control integration)
• Cable protection (strain relief, overmolding, long-term durability)
