Car Wide Voltage Isolated Long-distance Fast Charging Car Phone Charger Transmitter Coil Wireless Charging Module

1.Product Description

This is a wireless charging transmission module designed specifically for in car environments. Its core feature is wide voltage input to adapt to fluctuations in the car power supply, and electrical isolation is achieved through physical or circuit design to enhance safety. It supports mainstream Qi fast charging protocol and can actively match mobile phones to achieve fast charging. The module integrates multiple coils or large-sized precision transmitting coils, allowing stable charging within a certain vertical distance and lateral offset range, and is equipped with critical foreign object detection (FOD) function to ensure safe use. The overall system adopts industrial grade components and compact packaging to meet long-term reliable operation under harsh conditions such as high temperature and vibration inside the vehicle.

1. Core energy conversion: Its primary function is to convert and amplify the car power supply (such as 12V DC output from a cigarette lighter) into high-frequency AC power through the built-in inverter circuit, driving the transmitting coil to generate a high-frequency alternating magnetic field, thereby achieving contactless transmission of electrical energy.

2. Intelligent communication and control: The module acts as the "brain" and communicates bidirectionally with the receiving coil inside the phone through a magnetic field (following the Qi protocol). It actively identifies the connected device model, negotiates the maximum safe charging power supported by both parties (such as 5W, 10W, 15W fast charging), and controls the start stop of the entire charging process.

3. Comprehensive security protection: This is its key function. It continuously monitors the charging status, and once it detects metal foreign objects (FOD) such as coins or keys in the magnetic field, or senses abnormal temperature, voltage and current overload, it will immediately stop power supply to prevent overheating damage or risk.

4. Tolerant charging experience: By optimizing coil design (such as multi coil arrays), it expands the effective charging area. This allows the phone to start and maintain stable charging without precise alignment, even if there is a phone case separated by a certain distance or slightly tilted, improving the convenience of in car use.
