Product Overview

The In-Vehicle Wireless Charging Module is an embedded phone-charging assembly installed beneath or within vehicle interior trim. It is used in center consoles, armrests, storage trays, and rear-seat modules for passenger cars, commercial vehicles, and interior upgrade projects.

Key Advantages

Three-Coil Charging Area with 2 to 4 mm Working Distance

The three-coil layout provides a wider phone placement area than a single-coil design. When the module is installed beneath leather, trim plastic, or a thin tray surface, a 2 to 4 mm charging distance allows the charging face to remain hidden while reducing alignment sensitivity.

Automatic 5 W to 15 W Power Selection

The control system selects 5 W, 7.5 W, 10 W, or 15 W according to the connected phone and maintains charging efficiency up to 80%. This prevents a fixed-power module from overdriving low-power devices or underusing compatible fast-charging phones.

Defined Foreign-Object and Thermal Protection

Foreign-object detection blocks charging when keys or coins are placed on the pad. Thermal protection trips at 65°C ±5°C and recovers at 55°C ±5°C, while undervoltage and overvoltage cutoffs act below 4.5 V and above 13.5 V to prevent repeated overheating or unstable restart cycles.

Customization Capabilities

Charging Surface and Coil Layout
Coil position, active charging area, installation depth, and the upper trim structure can be adjusted for consoles, armrests, trays, and hidden charging surfaces.

Harness, Indicators, and Housing
Input connector, cable length, mounting holes, housing outline, LED location, light-pipe shape, and ready/charging/fault indicator behavior can be matched to the vehicle interior module.

Power and Protection Calibration
Charging profiles, temperature thresholds, fault lock time, foreign-object detection sensitivity, and firmware behavior can be calibrated for the selected trim material and thermal environment.

Quality Control

Installation Sample Verification
Approved samples are tested through the specified leather or trim cover at several phone positions. Coil alignment, indicator behavior, connector fit, and charging continuity are confirmed before the module and upper trim structure are released for production.

Protection and Recovery Verification
Keys and coins are placed on the charging area, and electrical and thermal faults are introduced to confirm cutoff, fault indication, the 10-minute lock period, and recovery after the condition is removed.

Continuous Charging and Final Inspection
Validation includes a 1,000-hour continuous charging test to check temperature rise and uninterrupted operation. Production units receive a final charging, LED-status, connector, and housing inspection before packing.
