[0022] The modular wireless interconnection socket system of this utility model includes a transmitter and a receiver, and its specific structure is as follows:

[0023] Transmitter structure: It is a modular socket body containing an energy transmission module (inverter circuit, transmission coil, positioning auxiliary components, 3.3kW-11kW power regulation unit), a data communication module (Wi-Fi / Bluetooth 5.0, protocol adapter module), a main control module (STM32 series MCU and coordination circuit), and an expansion interface module (standardized interconnection interface), which can be expanded with the required functions.

In electric vehicle scenarios, the positioning components and the separation detection circuit enable "stop and go".

[0027] Example 1: Electric Vehicle Charging Scenarios

[0028] Transmitter installation: The transmitter is embedded in the garage floor, with an IP65 waterproof shell and fluorescent positioning stripes on the surface. The power cord is a shielded flame-retardant cable, with an 8cm distance between it and the energy transmission coil. It also includes a built-in silent fan and foreign object detection sensor.

[0029] Receiver structure integration: The receiver is integrated into the Wuling Hongguang MINIEV vehicle BMS. The energy receiving module is adapted to a 36V battery and is equipped with a CAN bus interface to connect with the vehicle system.

[0030] Working process: The electric vehicle stops by passing the fluorescent stripe (with an error of 10cm). The infrared positioning sensor at the transmitter detects the vehicle, and the energy detection circuit starts charging at 3.3kW after confirming the match. The charging status is synchronized to the vehicle's instrument panel via the CAN bus, and the progress can be viewed on the mobile APP. When a metal foreign object is detected, the protection circuit cuts off the power, and the APP pushes an alarm. When the vehicle leaves, it automatically cuts off the power after being removed from the detection circuit.
